Stackable LCC/LCD Oven Owner’s Manual THEORY OF OPERATION

Danger!

Use care when working with nitrogen. Nitrogen presents an asphyxiation hazard. Handle nitrogen according the safe handling procedures listed in the material safety data sheet.

Figure 1. Stackable LCC/LCD Series Oven.

Version 1.1 15

3. Theory of Operation

3.1. The Stackable LCC/LCD Series Oven

The Stackable LCC/LCD Series Oven (Figure 1) offers HEPA (High Efficiency Particulate Air) filtration for processes where minimized contamination is essential. The removable HEPA filter is designed to provide a constant flow of 99.97% clean air to the product being heated. The HEPA filter with silicone seal provides 99.99% filtration.

The oven operator interface is located on the hinged control panel at the front of the oven (Figure 1). Power components are located on the equipment panel, behind the hinged control panel, for easy access (Figure 8). Electrical components are either touch-proof or are shielded with Lexan7 material to prevent accidental exposure during maintenance and troubleshooting.

The cooling fan is controlled on/off by an event relay in the Protocol 3 Control. The cooling fan is used for rapid cool-down at the end of the process cycle, or to maintain low temperature setpoints during process cycle. It may also be turned on at the start of a process cycle to assure that starting temperature is less than 70°C.

The nitrogen models have stainless steel water coil which permits rapid cool down and lower temperature operation. The nitrogen oven comes with an adjustable flowmeter a for adjusting purge rate, and needle valve for setting maintain rate, separate solenoid valves for purge and maintain operation and a pressure relief exhaust port. An exhaust fan which powers ON whenever the oven is running maintains consistent chamber pressure control with varied exhaust stack conditions.

The oven has a type 304-2B stainless steel interior and a type 304-#4 stainless steel interior. All interior seams are continuously welded on the insulation side. This protects the work chamber from contaminated air and permits chamber washing without damaging the insulation. Interior

THEORY OF OPERATION Stackable LCC/LCD Oven Owner’s Manual



Stackable units are available in air or nitrogen atmosphere models. Nitrogen atmosphere models are noted with an N suffix. Model numbers beginning with “LL*1-*” do not use a HEPA filter.

Figure 2. Protocol 3 Operator Interface.

ductwork may be easily removed for cleaning. Heater frame, fan wheel and motor shaft are constructed of stainless steel.

Two electropolished stainless steel wire shelves are provided. The shelves are removable and adjustable on two inch centers.

The LCC/LCD series design offers a stackable oven body. Multiple oven systems of two or three oven stack options are available. When operating multiple ovens, network the Despatch Protocol 3 controllers together with a Modbus communication option. Use the optional Despatch Protocol Manager software to enable customer PC control of multiple ovens.

3.2. The Protocol 3 Controller

The Protocol 3 is a microprocessor based digital temperature controller designed for simple and flexible oven operation (Figure 2). The Protocol 3 controller operates as a dual-functioning controller/high limit instrument. The control portion utilizes a time-proportioning voltage signal to control heating devices with minimal temperature fluctuations.

The high limit portion protects the product and/or the oven from overheating. If the product being processed has a critical high temperature limit, the high limit setpoint should be set to a temperature somewhat below the temperature at which the product could be damaged. If the product does not have a critical high temperature limit, the high limit setpoint should be set 5 to 15 degrees higher than the maximum programmed setpoint at which the oven will operate.

The Protocol 3 controller provides three primary operating modes:

 Manual: Oven operates continuously at a fixed temperature until turned off.  Timer: Oven operates at a fixed temperature for a user-selected time period, and then

automatically turns off.

 Profile: Temperatures

increase or decrease as defined by 255 segments that can be allocated to 64 ramp and soak profiles. The profiles can be linked to provide additional temperature combinations.

Stackable LCC/LCD Oven Owner’s Manual THEORY OF OPERATION



Each LCC/LCD oven uses one of two types of HEPA filters,

depending on the oven’s maximum temperature. Ovens that can

be heated to 260°C (500°F) use the Standard HEPA filter. Ovens that can be heated to 350°C (662°F) use the High-Temperature HEPA filter.

However, customers requiring a higher ramp rate while operating equipment below 260°C (500°F) may still choose to use the high-temperature HEPA filter:

 Standard HEPA filter ramp rate: 1.25°C (34.25°F)/minute  High-Temperature HEPA filter ramp rate: 5°C

3.3. HEPA Filters

The Stackable LCC/LCD Ovens use HEPA (High Efficiency Particulate Air) filters limit particulate size in the work chamber to 0.3 microns or less. Two different types of filters are typically used. While both filters are high-temperature filters in that they are designed for use in

thermal processing equipment, the “standard” HEPA filter is rated to 260°C ( 500°F) while the “high-temperature” HEPA filter is rated to 350°C (662°F).

3.3.1. Definitions

 Binder: Organic substance used in filter construction to provide the media with structural

strength

 Burn-Off: Process for eliminating the binder and D.O.P. contained in the filter from the

manufacturing and testing function.

 D.O.P.: Dioctyl Phthalate - Aerosol particles of submicron size used in testing phase to spot

defects or measure filter efficiency.

 HEPA: High Efficiency Particulate Air

Filter Packaging, Shipping and Handling

Packaging practice varies among the filter unit manufacturers. Filter units are typically packaged in cardboard cartons with varying approaches for strengthening the container and making it impactresistant. Shipping cartons are typically marked with a vertical arrow and "This Side Up" (Figure 3). A filter unit is placed in the carton so the pleated folds are vertical (running from top to bottom), versus side to side.

THEORY OF OPERATION Stackable LCC/LCD Oven Owner’s Manual

Caution!

Despatch does not recommend D.O.P. filter testing.



Ship, handle, store and install HEPA filters with pleats positioned vertically. Horizontally-positioned pleats risk breaking at the adhesive line of the filter medium. Horizontally-positioned pleats also collect

entrapped material on “shelves.” The accumulated weight of the

entrapped material may cause sag and lead to early failure of the filter unit.

18 Version 1.1

The filter is typically shipped in the original carton or package provide by the filter manufacturer. This carton or package provides good storage and maximum protection from dirt and moisture. Store and move HEPA filters upright in the shipping carton. Minimize handling of the filter. During installation, remove the filter from the shipping carton and install directly into the oven.

If an unpackaged HEPA filter unit must be placed with its face on the floor or other surface, clear the surface entirely of every object or irregularity which might damage the filter pack.

3.3.2. HEPA Filter Validation Testing

Despatch Industries guarantees the HEPA filters will meet specified efficiency ratings when the following recommendations are followed:

 The filter is properly installed  The filter is run at or below 200°C, at a constant temperature  The filter is run before burn-in

3.3.2.1. D.O.P. Testing

D.O.P. testing uses aerosol particles of submicron size to spot defects or measure filter efficiency. Degenerative by-products of this test are distributed throughout the oven chamber upon heat-up. Despatch does not recommend D.O.P. filter testing.

3.3.2.2. Class 100 Testing

Despatch guarantees a Class 100 environment within the oven. This classification is based on measurement of the particulate level within the oven work chamber.

All rights reserved. No part of the contents of this manual may be reproduced, copied or transmitted in any form or by any means including graphic, electronic, or mechanical methods or photocopying, recording, or information storage and retrieval systems without the written permission of Despatch Industries, unless for purchaser's personal use.

Stackable LCC/LCD Oven Owner’s Manual THEORY OF OPERATION Version 1.1 19

Class 100 testing may be performed before or after a proper filter burn-in procedure has been performed. Despatch guarantees Class 100 condition measurements based on two methods of test. The direct method employs an extraction-type particulate analyzer. The indirect method involves particle settling over a specified period of time onto a clean disk.

3.3.2.3. Validation Testing

Despatch recommends the following test sequence for pharmaceutical Class 100 ovens.

1. Proper installation of the HEPA filters (Section 0).

2. Ambient air challenge to determine integrity of oven chamber and filter gaskets.

3. Proper filter burn-off procedure.

4. Class 100 testing inside the work chamber.

3.3.2.4. HEPA Filter Burn-off Process Not Necessary

HEPA filters contain a binder material which protects the filter media during production and shipping. Smoke produced from burning this binder at elevated temperatures is undesirable during normal oven operation. Burning off the binder will ensure a clean process at elevated temperatures. However, when the binder is burned out of the filter media, the filter becomes very fragile: too fragile to withstand normal shipping and handling. For this reason, Despatch does not perform the burn-off procedure. The burn-off process is not necessary at temperatures under 200°C.

3.3.3. HEPA Filter Unit Replacement

Periodic replacement the HEPA filter unit due to:  Resistance, or pressure drop, across the filter unit. Maximum level of resistance in inches

(water gauge) will vary depending upon the operation of the filter and the available fan capacity. Adequate fan capacity must be available.

 Loss of efficiency (leakage), determined from air-sampling measurements made downstream

of the filter unit.

 Visible damage or rupture of the filter media in a unit.  Change in process application.  Excessive build-up of lint or combustible particulate matter on the filter unit.  Water droplets in airstream through filter, free water (RH = 100%), will saturate filter very

quickly and may cause burnout or holes in burned off filter media.

 High level of radiation in the vicinity of the filter unit.

3.3.4. HEPA Filter: Magnehelic Pressure Gauge

The LCC Series oven is equipped with a Magnehelic pressure gauge which measures the pressure in front of the HEPA filter (Figure 4). As the filter becomes dirty, pressure increases. Despatch

recommends changing the filter when the pressure is 1” w.c. greater than when the filter was first installed (Refer to section 4.3 for filter replacement).

Since pressure can be affected by many factors involved in the installation, it is important to record the pressure of a new filter as a baseline. Recorded pressure readings allow for new readings to be periodically checked against this baseline. Use Table 2 for recording this information (See Section 8.1 for a blank worksheet).

For a nitrogen atmosphere oven, pressure readings also give an indication of the integrity of the seals. If the pressure recorded in Columns D or E decrease over time, inspect the oven seals.



Each LCC/LCD oven uses one of two types of HEPA filters,

depending on the oven’s maximum temperature. Ovens that can

be heated to 260°C (500°F) use the Standard HEPA filter. Ovens that can be heated to 350°C (662°F) use the High-Temperature HEPA filter.

However, customers requiring a higher ramp rate while operating equipment below 260°C (500°F) may still choose to use the high-temperature HEPA filter:

 Standard HEPA filter ramp rate: 1.25°C (2.25°F)/minute  High-Temperature HEPA filter ramp rate: 5°C (9°F)/minute

Warning!

Make certain power is disconnected from the oven before removing or replacing the HEPA filter. Observe all applicable safety procedures.

Caution!

The HEPA filter is fragile and care must be taken to avoid damage during installation. If a filter unit is dropped, whether in the carton or not, examine it carefully for damage.

Caution!

The HEPA filter must be installed so that unfiltered air cannot leak past the unit.

Refer to installation instructions provided by filter manufacturer for additional details..

4.3. HEPA Filter Installation

Not all LCC/LCD ovens come equipped with a HEPA filter. This HEPA filter installation section applies only to ovens designed for ISO Class 5 (Class 100) use, which are equipped with a HEPA filter. For a complete explanation of model numbers, refer to Section 1.5.1.

Two different types of filters are typically used. While both filters are high-temperature filters in

that they are designed for use in thermal processing equipment, the “standard” HEPA filter is

rated to 260°C (500°F) while the “high-temperature” HEPA filter is rated to 350°C (662°F).

4.3.1. HEPA Filter Burn-Off

4.3.1.1. HEPA Filter Burn-Off Process

The burn-off process takes place in any equipment where a new HEPA filter is used at temperatures above 180°C / 356°F. Expect smoke, possibly a pungent odor and a light residue on interior surfaces. This results from oxidation of the binder. Most of the binder will leave the filter after running at a temperature of 260°C/500°F for 48 hours. Check the oven for particles or the exhaust for smoke and odor to determine that the process is finished.

4.3.1.2. Location of HEPA Filter Burn-Off Process

Select a location for the burn-off process where generated smoke and odor will be ventilated with the least amount of interruption and inconvenience. Ideally this will be in the final location for the oven. However, it may be a receiving dock, some well ventilated space or even outside if the weather is acceptable. If this location is a very clean area, pay special attention to an exhaust hook-up that fully captures the smoke and odor produced. The post-Burn-off cleaning (that is, oven wipe down) may also generate dust. So take care if in a clean room.

4.3.1.3. Recommended HEPA Filter Burn-Off Process

1. Locate the equipment exhaust opening where chamber air is being expelled. a. If the oven filter is burned off in a clean area, be sure to handle the equipment exhaust

appropriately.

b. If the equipment is large and the exhaust stack is a permanent service connection, connect

the equipment and exhaust stack before the burn-off process.

c. If the equipment is small with no permanent exhaust duct required, arrange a temporary

connection out of the clean area that will handle the maximum temperature of the equipment. Direct the smoke and odor outside, or to a highly ventilated area.

2. Set the temperature control at the maximum process temperature. a. Silicone: Ramp at 1.25°C/min to 260°C and soak for 48 hours. b. Media Pack: Ramp at 1.25°C/min to 260°C and soak for 48 hours. c. High-temperature (Figure 14):

i. Option 1: Ramp at 1.7°C/min (or up to 5°C/min) to 350°C and soak for 48 hours.

ii. Option 2: Ramp to process temperature and soak for three consecutive three-hour

segments over 48 hours.

If the equipment must be moved after the burn-off process, use considerable care.  The binder which strengthened new filters is now burned-off

and the media is very fragile.

 Rough handling of either the filter alone or the equipment

with the filter installed is not recommended as it may tear the media and lead to reduced filter efficiency.

 Removal of the filter after heating can also result in damage

to the frame seal, and is only recommended when replacing the filter.

Stackable LCC/LCD Oven Owner’s Manual MAINTENANCE Version 1.1 43

6. Maintenance

Do not attempt any service on this oven before opening the main power disconnect switch.

6.1. Checklist

 Keep equipment clean. Gradual dirt accumulation retards airflow. A dirty oven can result in

unsatisfactory operation such as unbalanced temperature in the work chamber, reduced heating capacity, reduced production, overheated components, and the like. Keep the walls, floor and ceiling of the oven work chamber free of dirt and dust. Floating dust or accumulated dirt may produce unsatisfactory work results. Keep all equipment accessible. Do not permit other materials to be stored or piled against it.

 Protect controls against excessive heat—particularly controls, motors or other equipment

containing electronic components. Temperatures greater than 51.5°C (125°F) should be avoided.

 Establish maintenance and checkup schedules. Do this promptly and follow the schedules

faithfully. Careful operation and maintenance will be more than paid for in continuous, safe and economical operation.

 Maintain equipment in good repair. Make repairs immediately. Delays may be costly in

added expense for labor and materials and in prolonged shut down.

 Practice safety. Make it a prime policy to know what you are doing before you do it. Make

caution, patience, and good judgment the safety watchwords for the operation of your oven.

 Inspect oven seals if pressure readings decrease over time (Refer to Section 3.3.4 as well as

Table 2, Columns D and/or E)

6.2. Lubrication

Fan motor bearings are permanently lubricated. All door latches, hinges, door operating mechanisms, bearing or wear surfaces should be lubricated to ensure easy operation.

6.3. HEPA Filter Replacement

Refer to section 4.3 for filter replacement.
