Dryer External Connections

Once assembled, installation requires connection of: pneumatic air line, electrical, intake and output material lines.

Compressed Air Connection

Connect an air supply to the air regulator’s IN port using a female 1/4” NPT pipe fitting.

An operating air pressure of 80 psi (5.5 bar) while the vacuum generator is running is required for proper operation of the Dryer. Setting the air pressure to 85 psi while the machine is idle will usually attain the desired 80 psi while the vacuum generator is running.

If your air supply has oil in it, add an oil separator (coalescing filter). Oil in the air will combine with dust drawn from the Vacuum Chamber forming a paste inside the vacuum generator. It will stop working and require cleaning.

Observe the air pressure gauge to be sure the pressure maintains 80 psi (5.5 bar) while the vacuum generator is running as you check and adjust the regulator. If pressure drops below 80 psi, adjust the regulator. If the pressure cannot be maintained at 80 psi (5.5 bar) while the vacuum generator is running, then the air supply line is not adequate.

Do not supply Dryer with a lubricated air supply. Damage to Dryer may result. Use only a clean, dry, oil-free air supply.

Pinch Hazard - Keep fingers clear of seal deck, the mating surface above the Vacuum Chamber seal.

When air pressure is turned on and the Vacuum Chamber Lift Switch is flipped up, air cylinders lift the Vacuum Chamber off of the slider rails and up to the seal deck closing the gap between the top of the Vacuum Chamber and the seal deck.

Confirm Correct 3-Phase Electrical Connection

THREE PHASE Unit - CONFIRM proper 3-Phase power connection prior to loading material. Failure to confirm proper 3-phase connection can result in reversed blower rotation and damage to blower if the blower sucks in material from heating hopper rather than blow heated air into heating hopper.

To confirm proper 3-phase connection following these instructions:

Turn power on using main power switch.

There are two methods to confirm proper 3-phase connection:

Incorrect 3-phase connection will result in reversed blower rotation. Both methods for checking correct 3-phase connection involve testing the blower rotation.

Method one requires the disconnecting the 2-inch hot air hose from the heating hopper and manually turning on the blower. The air from the blower should blow out of the 2-inch hose. Air should not suck into the hose. If air does not blow out and sucks in, the 3-phase connection is NOT correct.

Method two requires the removal of the left side panel to view the blower and confirm blower rotation on power up. Rotation must be clockwise as indicated by the red arrow.

1. From the Main Screen press to highlight Manual Operations. Press ENTER.

2. Press to select Operate Outputs. Press ENTER.

3. Press

to select Blower. Press ENTER to start blower. Press ENTER again to stop blower.

Startup and Operation

This section will help you understand what the dryer is doing during operation from a cold start. There are 3 concurrent operations. Heating, Vacuum and, Retention. Cold startup begins with Preheat. Preheat only occurs before the first cycle of the dryer’s initial startup, otherwise each cycle begins with material heating. The vacuum operation pulls and holds a vacuum on the material for at least the Vacuum Time Set-point (or longer if material remains in the Retention Hopper). The Retention operation holds the dried material in the Retention Hopper, blanketing the material with hot, dry air, until the material is conveyed away.

Important: Inspect the VBD, verify that machine is clear of all material from heating hopper, Vacuum Chamber and Retention Hopper. To facilitate a Clean Out, use the Clean Out function accessible from the home screen.

Startup and Operation Instructions

1. ENSURE HATCH IS CLOSED. There is a hatch located on the upper

Heating Hopper. Ensure all 3 latches are closed. Also be sure the removable Lower Retention Hopper is in place.

2. Load material into the Upper Heating Hopper. Wait for the Heating Hopper to fill with material before starting the Dryer.

3. Turn on Main Power by rotating the 25 AMP Main Disconnect Handle to the Red ON position. This powers up the VBD-150 Dryer.

On initial power up of the VBD, the Control Panel powers ON automatically. If the main power is ON but the Control Panel is OFF, press and hold the Red Power Button located on the Control Panel for 2 seconds. (Note: The VBD’s Control Panel can be powered OFF without powering down the Main Power by pressing and holding the Red Power button for 4 seconds).

4. After material has been loaded into the Heating Hopper, select Run Dryer and press the ENTER button.

5. The display will show the Pre-Start screen. On this screen is:

Setpoint Temp – This is heat hopper inlet temperature. By the end of

the preheat cycle time, all material in the Heating Hopper will be heated to this temperature. By default, the Setpoint temperature is set to 150 °F. See Recommended Heat Temperatures on page 19 for general temperature recommendations or contact the material manufacturer.

Preheat Time – This is the duration of heating from a cold start.

Vacuum Time – This is the minimum duration of a vacuum cycle.

Actual vacuum cycle times will vary according to the throughput. The default vacuum time is 20 minutes. In the vast majority of drying operations, this time is adequate and does not need to be adjusted. Special circumstances may require different vacuum times. Please consult a Maguire Dryer Technical for additional information.

By default, START is selected (location of cursor). If the settings you desire have been entered previously, simply pressing ENTER once more will start the machine. Otherwise use the arrow buttons to navigate to the desired settings for adjustment, then press ENTER. The display will highlight the adjustable digit.

Rev. August 31, 2016 – VBD-150

BD® - Vacuum Dryer®

Maguire Products, Inc.

What is happening when the dryer is running:

During the Pre-heat operation material in the heating hopper is brought up to temperature (T1s). Preheat time is determined by the specified Preheat Time on the Pre-Start screen (timed preheat, default 35 minutes) or by the Preheat Setup Auto option, which sets an inlet to outlet temperature delta and a minimum preheat time.

After pre-heat, approximately one third of the material in the heating hopper is dispensed into vacuum chamber, and the first vacuum cycle begins. Each vacuum cycle has a minimum vacuum time, set on the Pre-start screen, or the main run screen (VTs). (default is 20 minutes).

The loader loads the Heating Hopper with new material as the Vacuum Chamber receives the heated material and heating cycle begins concurrent to vacuum cycle (the first vacuum cycle is timed). The new batch of material in the upper portion of the heating hopper will take less time to heat. Minimum time in the heating is dictated vacuum time.

After first vacuum cycle, material is then dispensed into retention hopper ready for use. Material in the retention hopper is blanketed with dry air.

The rate of consumption of dried material from the retention hopper ultimately dictates the amount of time that the material will be preheated and under vacuum. Examples: If it takes 25 minutes to deplete the retention hopper, the vacuum cycle will run past its 20 minute setpoint (pre-start screen) to 25 minutes. This is normal operation. However if the retention hopper is depleted in 15 minutes and the vacuum time is set to 20 minutes, there will be a 5 minute window where no material is available. This indicates that the throughput of the dryer has been exceeded. If the Throughput Alarm is enabled (Alarm Setup), a Throughput Alarm (Alarm Code 20) will be triggered.

Parameters

All Maguire VBD controllers operate according to certain internal PARAMETERS. Because customer requirements vary widely, we have made parameters accessible for change through the keypad. In most cases, these parameters will never need to be changed. Some parameters that are routinely adjusted values are adjustable from the main display. To access and edit the parameters, see Changing Parameters in this section:

Changing parameters can have an impact on the Dryers performance. It is highly recommended that a supervisor change the default Program Mode password to protect the values. Prior to making any changes, make sure you understand what you are doing. If in doubt contact a Maguire Dryer Technician before making changes to your dryer.

Vacuum Chamber High Level – weight - 00035

Amount of material dispensed into the Vacuum Chamber from the heating hopper. Also known as the “Fill Weight”.

Vacuum Chamber Low Level – weight - 00005

Two conditions are triggered by VTL. When in Clean Mode, the Vacuum Chamber fill valve will be open when the amount of material in the Vacuum Chamber is at or below this weight. When starting in Auto Cycle, the “material in Vacuum Chamber” warning will be triggered when the amount of material is at or above this level.

Retention Hopper High Level – weight - 00035

Amount of material (the high level) dispensed into the Retention Hopper from the Vacuum Chamber.

Retention Hopper Low Level – weight - 00005

Three conditions are triggered by RTL. When in Clean Mode, the Vacuum Chamber dump valve will be open when the amount of material in the Retention Hopper is at or below this weight. When starting an Auto Cycle, the “material in Retention Hopper” warning will be triggered when the amount of material is at or above this level. When in Auto Cycle, the amount of material in the Retention Hopper must be at or below this level in order for the Vacuum Chamber to dump.

Vacuum Fill Adjust (Retries, percent) – 00310

Two part parameter. The first three digits are the number of retries to fill the Vacuum Chamber (default 3 retries). Last two digits are the minimum allowable percent under the targeted maximum fill weight of the Vacuum Chamber (VTH parameter). After the third failed retry the “Low Batch” alarm is generated while the VBD continues to retry.

Heat Hopper Dump Delay - Seconds - 0004

Delay in seconds between the heating system shutdown and material dump from the heating hopper to the Vacuum Chamber. This delay allows time for the blower to stop.

Controls the Vacuum Chamber Dump Alarm. Format: XXXYY - XXX = percentage, YY = number of retries When the vacuum chamber dumps material into the retention hopper, if less than 50% of the material that should have dropped is detected in the retention hopper, a dump retry will occur. After 3 failed retries a VC DUMP alarm will trigger.

Residence Alarm – pounds / minutes - 05120

When the Residence Alarm is enabled, this parameter will determine when a residence alarm will occur. This parameter contains two variables. The first two digits are weight (in lbs or kgs) and the last three digits are minutes. For example, if after 120 minutes there are less than 5 lbs (or kgs) of material removed from the retention hopper, the Residence Alarm will sound (if enabled, see the Alarm Setup menu).

Batch Mode – weight (lbs/kgs) – 00000

The amount of material in pounds or kilograms that will be dried during a batch run.

Loader Trip Point – weight (1/10 pound or kilogram) – 00005

Heating Hopper Volume – 10ths of cubic feet or 10ths of liter.

The amount of material that the heating hopper can hold taking into account dead space at the top and how far the loader hangs into the heating hopper. This parameter is used to calculate the beginning of an auto shutdown when loader #1 is set to auto. Installation of an optional heating hopper extension would necessitate changing this parameter.

Heating Hopper High Level (%) – 00095

The level, expressed as a percentage, that the heating hopper will be filled to when Loader #1 is set to AUTO (and the heating hopper loader signal cable is wired in series to the Loader #1 control relay). Note that the deadband is is 5%.

Maintenance

Drain and purge Air Filter / Regulator

The purpose of the air filter is to remove moisture and contaminants from the air supply and protect the air components of the Dryer. The air filter must be periodically purged of moisture.

Do not supply Dryer with a lubricated air supply. Damage to Dryer may result. Use only a clean, dry, oil-free air supply.

Maguire Products, Inc.

Air Pressure Adjustments

Air Pressure

Air pressure affects the ability to draw a high vacuum. We recommend a pressure setting of 85 PSI while the dryer is resting idle. Air is used when the vacuum generator is running so observe the PSI while the Dryer is drawing a vacuum. The gauge should continue to read this setting even when the vacuum unit is on. If it does not maintain pressure your supply line is not sized properly.

The ZERO point of the load cells is now set properly. FULL weight calibration may also be done at this time, however, it probably is NOT NECESSARY. When load cell readings shift due to rough handling, the entire range of readings from ZERO to FULL shift together. The ZERO weight calibration routine resets the full range of the cells and, therefore, corrects FULL weight readings as well.

Full Weight Calibration

When SETTING FULL WEIGHT, BE SURE you know the exact weight (in grams or pounds) that you are adding to the chamber. Place this weight in the chamber.

Enter the EXACT weight that you have placed in the chamber. Weigh units are in tenths of a pound or tenths of a kilogram depending on the weigh units set in LOAD Cell Setup menu. The weight should be close to 35.0 lbs or 16.0 kilograms.

After FULL weight calibration, if the display says (BAD CELL), the weight you are using does not match the weight you entered, the chamber is not free to move, OR the load cells are bad.

Full Weight Calibrations - Full weight calibration will be done on both the Vacuum Chamber and Retention Hopper. It is recommended to use a known weight of material for the Full Calibration. Place approximately 35 lb of material into the Heating Hopper. Using Manual Operations, Operation Outputs, Vac Cham Fill, dispense the material from the Heating Hopper to the Vacuum Chamber prior to entering the Full Calibration Routine.

If material totals are being observed loadcell full weigh calibration is recommended periodically (approximately every six months).

Clean Out Procedure

Clean Out dumps the Heating Hopper or the Vacuum Chamber or both at the same time. The following explains how to perform these procedures.

HEATING HOPPER HOT SURFACES:

As with all dryers, there are HOT SURFACES to avoid. Temperatures can reach 350F, (180C). Typically these surfaces are not at dangerous temperatures, however all hot surfaces should be avoided.

Do Not Perform a Clean Out Unless VBD-150 Dryer is First Properly Shut Down.

For proper shutdown proceedure, see Startup and Operation on page 19.

During the Clean Out, keep hands and tools clear of all valves. DO NOT reach into machine during Clean Out.

Using the Heating Hopper Dump Chute (Optional)

For easy cleanout, material in the Heating Hopper can be evacuated using the included Heating Hopper Dump Chute. The Heating Hopper has a front side door for access to the full internal height of the Heating Hopper. The Heating Hopper is non-removable. Prior to opening the front access door, removal of all material is recommended. To evacuate material from the Heating Hopper using the Heating Hopper Dump Chute, use the following procedure.

Note: use of the chute is optional. Material can be dumped into the vacuum chamber, then into the retention hopper and conveyed away from the VTA at the base of the dryer.

Lower the Retention Hopper sealing collar located at the bottom of the Vacuum Chamber. The sealing collar is attached to the base of the Vacuum Chamber with magnets. Detach the sealing collar by pulling down.

Lower the Vacuum Chamber by switching down the Vacuum Chamber Lift Switch.

Alarms - Cause and Solution

Typically problems are indicated by an alarm condition on the Dryer controller’s display with an audible alarm and a flashing strobe light. The following alarm troubleshooting chart will describe the alarm condition and possible causes and solutions.

*** ALARM:03 ***

SETPOINT EXCEEDED

Press Any Button To SILENCE alarm

NO HEAT

Troubleshooting:

Problem: The blower is not running.

Motor contactor overload relay has tripped. See wiring diagram on page 73 for Blower Motor Contactor. Item # 3, overload relay on wiring diagram. This alarm will trigger a dryer shutdown.

Solution: Reset contactor. Check that blower motor shaft is not locked. Check line voltage to machine; make sure voltage is not too low which can cause an increase in amperage. Check that power source has not lost a phase.

Problem: No heat or inadequate heat detected by the Heating Hopper inlet RTD.

This alarm is triggered by the NH1 parameter. NH1 parameter is the maximum time limit, in seconds, after the heat cycle begins, during which one of the following two conditions must be detected: Either the temperature must climb 20 degrees, or the temperature must move at least 20 percent toward the target temperature. If neither condition is met the “NO HEAT” alarm will sound. Such an occurrence would signal a failure of either the heater or the airflow from the blower. This parameter and consequent alarm protects the heater from burn out in the event the blower fails or airflow is blocked.

Solution: Check for airflow from the blower. Check blower inlet obstruction, check that 2” air duct from blower to heater is not detached, obstructed or perforated. Check 2” air duct from top of heater to heating hopper inlet for detachment, obstruction or perforation. Check resistance across heater. Disconnecting heater from circuit is not necessary to measure resistance. Measurement should read 80 ohms. See wiring diagram on page 73. If the dryer’s heater shorted, the result would be a trip of the breaker or fuse supplying power to the VBD-150 dryer.

Problem: The heating hopper air inlet temperature has exceeded set-point by an excessive amount.

If the Heating hopper air inlet temperature (T1a sensor) goes 20F over setpoint (PTS parameter), this fatal alarm is triggered.

Problem: The heating hopper air inlet temperature has drifted above set-point.

If the Heating hopper air inlet temperature (T1a sensor) is over the degrees specified in parameter OT1 (default 6° F or 6° C) for a time greater than the time in seconds specified in OT1, then the alarm is triggered and the heater output will drop by 20%. The alarm will occur but the machine will keep running. See OT1 parameter for more information.

Solution: No solution is necessary under normal circumstances as the dryer is alerting to a temperature adjustment. If this alarm continued to repeat, contact Maguire Technical Support.

Problem: The dryer failed to pull a vacuum after three attempts.

Dryer attempted to pull a vacuum 200mm below atmosphere within 45 seconds (default). Dryer attempted three times (number of default retries). After each attempt vacuum was equalized and vacuum gates were opened and closed in an attempt to reseal the Vacuum Chamber (possible debris or pellets preventing adequate seal). Defaults are controlled the NVT parameter (retries and seconds). This alarm is non-fatal. Dryer will continue to reseal after alarming.

Solution: If Dryer continues to alarm, check: compressed air connection and pressure (dryer’s regulator should be reading 85psi). Check for debris in seals above and below Vacuum Chamber.

Retention Hopper Not Present

If retention hopper loadcell is reading 6.6 pounds (3000 grams) below tare during AUTO run, this alarm is triggered and Dryer stops (fatal). This alarm is generally caused by a missing Retention Hopper but may also be caused by dryer Retention Hopper load cells having been zero calibrated while material was in the Retention Hopper, or faulty loadcells.

Solution: If Retention Hopper is missing replace Retention Hopper. If Retention Hopper is in place, ensure the tank is empty and zero calibrate the load cells. If load cells are damaged, a zero calibration may detect this.

Problem: RTD (temperature sensor) reading is above or below max/min reading

RTD Sensor is probably disconnected or damaged. Check temperature display reading in a cool state. Temperature should display room temperature. If reading is below -25C or above 450C RTD sensor has failed.

Solution: Contact Maguire Technical Support for a replacement RTD Sensor.

Problem: Maximum Fill Time (VFT parameter) has been reached before target material weight (VTH parameter) has been achieved.

This alarm is triggered when the VFT parameter has been reached (Vessel Fill Time) before the VTH (Vacuum Chamber High level), indicating shortage of material in heating hopper or possible valve jam. The outcome of this alarm is controlled by the Material Shortage Alarm settings. See page 27.

Solution: Check material supply. Check Vacuum Chamber fill valve located at the base of the heating hopper.

Problem: Air pressure sensor has detected air pressure below 50 psi.

Solution: Check exhausting lockout valve located on the front lower left

side of VBD-150. Ensure that the valve is open. Check pressure of air supply.

Problem: The temperature safety switch has opened due to an overheat condition.

Located on the top of the Heater Tube is a Temperature Safety Switch. If the temperature of the heater exceeds the safety switch maximum, this switch opens, shutting down the entire dryer (FATAL Alarm).

Solution: Allow the dryer to cool. Open the left side panel of the dryer and locate the Heater Tube Safety Switch on the upper side of the stainless steel heater tube. Press the red safety switch button to reset the Temperature Safety Switch. If problem occurs repeatedly, contact Maguire Technical Support.

Problem: The Vacuum Chamber is missing.

If Vacuum Chamber load cell is reading 4.5 pounds (2000 grams) below tare during AUTO run, this alarm is triggered and Dryer stops (fatal). This alarm is generally caused by a missing Vacuum Chamber but may also be caused by the dryer Vacuum Chamber load cells having been zero calibrated while material was in the Vacuum Chamber.

Solution: If Vacuum Chamber is missing replace Vacuum Chamber. If Vacuum Chamber is in place, ensure the chamber is empty and zero calibrate the load cells. If load cells are damaged, a zero calibration may detect this.

Problem: The Retention Hopper is missing.

If Retention Hopper load cell is reading 6.6 pounds (3000 grams) below tare during AUTO run, this alarm is triggered and Dryer stops (fatal).

Problem: The throughput of the dryer has been exceeded.

This is an optional alarm (under alarms menu), defaulted to enabled. This alarm is triggered when the Retention Hopper low level has been reached before the vacuum timer has elapsed. This means demand for material has exceeded dried material supplied. This alarm is non-fatal, dryer continues to run.

Solution: This is cause by exceeding material demand.

Problem: Dryer failed to pull vacuum down to target vacuum pressure set in VPL parameter.

Dryer attempted to pull a vacuum down to target vacuum pressure within 120 seconds (default value in LVT parameter).

Possible causes and Solution: If dryer alarms, check: compressed air connection and pressure (dryer’s regulator should be reading 85psi). Check for debris in seals above and below Vacuum Chamber. Alarm may also have been caused by a vacuum leak. Contact Maguire technical support if cause is not found.

Problem: Material has been in the retention hopper too long.

This alarm is triggered by the RAL parameter. When the Residence Alarm has been enabled, this alarm will sound if not enough material has been removed from the retention hopper in the time specified in the RAL parameter. For more information, see the RAL parameter on page 32.

Solution:

To prevent this alarm: decrease fill weight, or turn on Fill Weight Adjust (Material Setup menu).

Batch is complete

This alarm triggers at the end of a batch run, the end being defined as the time at which the retention hopper is depleted to the HHL parameter level after the final vacuum chamber dump of said batch run.

Material Shutdown

This alarm triggers if the Material Shortage alarm is set to "SHUTDOWN" and is it determined that the heating hopper has been fully depleted of material via the VFA parameter criteria. When this alarm triggers, the VBD enters a Shutdown state automatically. This alarm can be useful. For example: at the end of the day, one can intentionally run the heating hopper empty (by turning off its feed loader) and have the VBD automatically initiate a shut down at the appropriate time.

Material Ready

If the Material Ready alarm is enabled under the "Alarm Setup" menu, this alarm will trigger after the first and only first batch of material has completed a full vacuum cycle. After 15 seconds, the audible portion of this alarm will automatically silence. The first batch of material will remain under vacuum indefinitely until this alarm is cleared. There are two main purposes of this alarm:

1. To alert the operator that dry material is ready for the process.

2. To act as a hold-back, when necessary, giving the operator additional time to prepare the process.

Auto Shutdown

This alarm triggers when an Auto Shutdown, that is, a shut down at a predetermined time, has commenced. "Commencement" is defines as the time at which the final vacuum chamber fill has occurred.

Heating Hopper Material

On VBD's with an optional Heating Hopper Level sensor, this alarm triggers when the "HH Mat. Level" alarm is enabled under the "Alarm Setup" menu and the level in the heating hopper has dropped below the HHA parameter value.

Material Temperature Alarm

When the Material Temp alarm is enabled under the "Alarm Setup" menu, during any instance where the Heating Hopper is called upon to dispense material into the vacuum chamber and the T2 (heating hopper exit) temperature is below the ESM parameter level, this alarm will trigger. Its purpose is to alert the operator that insufficient heating has occurred, most likely from a process throughput that exceeds the capacity of the VBD.

VC Dump Failure

When the VC Dump alarm is enabled under the Alarm Setup menu, vacuum chamber dumping is monitored. When is has been determined that the vacuum chamber has failed to dump sufficient material into the retention hopper after a certain amount of retries as defined by the VDR parameter, this alarm will trigger. The vacuum chamber will continue dump attempts indefinitely, until the "successful dump" criteria is satisfied, at which point this alarm will auto-silence.

Theory of Operation / Performance

THEORY OF VACUUM DRYING

Water boils at 212 F (100 C) degrees. However, this is only true at sea level, which is to say at standard atmospheric pressure, which is 14.7 pounds/sq in (1 bar), also expressed as 29.92 inches (760mm) of Mercury (Hg).

At lower pressures the boiling point of water is reduced.

Standard atmospheric pressure can support a column of Mercury 29.92 inches (760mm) high. If we pull a perfect vacuum above a column of Mercury, the mercury will rise in that column 29.92 inches and, for that reason, the number we can expect to read on the vacuum gauge, at full vacuum, is 29.92 inches. Lesser vacuums read lower numbers. No vacuum reads zero.

When water is subjected to a vacuum level of 25 inches (635mm) of mercury, it will boil at 133F (56C) degrees. When plastic pellets are heated to 160F (71C) degrees, or greater, and subjected to a vacuum of 25 inches (635mm), the water vapor within wants very much to boil. This increased molecular activity within the pellet and the greatly reduced pressure surrounding the pellet drives the moisture from the pellet in a remarkably short time. This then is the reason for the remarkable short drying time of a vacuum dryer.

PERFORMANCE

The true measure of a dryer's performance is determined by the moisture content of the resin after the dryer has done its job. Resin moisture content, however, is not easily measured, so dryer manufactures use other criteria to assure performance.

Conventional "desiccant" dryers use DEW POINT as a measure of performance. This is a measure of the dryness of the air passing over the resin, but not the dryness of the resin itself.

For example, for a particular resin, experience may tell us that 180f (82c) degree air dried to minus 40 dew point, and passed over the material for 4 hours, is sufficient to reduce the moisture content of that resin to the required level of dryness.

Since our VBD Dryer does NOT use dry air, we have no "dew point" to measure.

In our case, for the same resin, experience tells us that a vacuum of 25 inches (635mm) applied for 20 minutes to material that has been heated to 180f (82c) degrees, is sufficient to reduce the moisture content of that same resin to the correct level of dryness.

Therefore, just as desiccant driers assure dry material by measuring temperature and DEW POINT over time, we assure dry material by measuring temperature and VACUUM over time.

When we assure that a certain temperature has been reached and a certain vacuum level achieved for a correct length of time, we can then be assured the material is dry.

You may visually assess performance by monitoring temperature and vacuum levels yourself. Of course, the final test is in the quality of the product you manufacture. We welcome your comments and observations.
