Observe the safety instructions of the pump manufacturer.

The mixtures extracted from the inner chamber must be carried away making sure that there is no danger by ignition of these atmospheres. Otherwise, use flame arresters (flame flash-through barrier). For installing a flame arrester, please contact the BINDER INDIVIDUAL team.

In case of an explosion, the flame can be suctioned into an in-house vacuum system thereby resulting in further explosions.

VDL (E2.1) 04/2014 page 15/107

DANGER

Danger due to flame flash-through with in-house vacuum system.

Danger of death.

 We recommend installing a flame arrester (flame flash-through barrier) according to EN

12874 between the VDL vacuum drying oven and the in-house vacuum system.

Sparking in the pump motor or the switching elements, electrostatic discharges, as well as hot pump parts can ignite solvent vapors in the event of an error. To minimize this risk, use an ATEX (Directive 94/9/EC) compliant vacuum pump suitable for suction from Zone 0 or 1 and, if appropriate, from the zone of its installation site.

DANGER

Ignition of emerging solvent vapors due to sparking in the pump motor or the switching elements, electrostatic discharges, hot pump parts.

Explosion hazard.

Danger of death.

 Use only suitable, explosion-proof pumps  Operate the pump in a stationary position and secure it so it is immobile.  Install a fixed and conductive suction line to the vacuum connection (13).  Install a fixed and conductive exhaust pipe in case it may conduct ignitable solvent con-

centrations. This should be avoided by sufficient solvent condensation e.g., in an exhaust waste vapor condenser

 When using ATEX (Directive 94/9/EC) non-compliant pumps: Provide a current-

dependent, delayed protective device for the pump (for the triggering time of this protective device, see the manufacturer’s specifications). The protective and monitoring device must not be able to turn on independently again or be released.

 When using ATEX (Directive 94/9/EC) non-compliant pumps: Install the switch gear box

outside the hazardous area or provide it with explosion protection.

 Assure equipotential bonding between the pump housing and the housing of the VDL

vacuum drying oven by the connected equipment grounding conductors of both units.

The ATEX (Directive 94/9/EC) compliant pumps offered by BINDER provide an integral protective device.

The ATEX (Directive 94/9/EC) compliant pumps offered by BINDER provide an integral explosion proof switch.

Confirm that the vacuum source is designed for a gas inlet temperature corresponding to the used drying temperature, or take appropriate measures to cool down the extracted vapor before it enters the vacuum source.

VDL (E2.1) 04/2014 page 16/107

The ATEX (Directive 94/9/EC) compliant vacuum pumps offered by BINDER are designed for a gas inlet temperature of 40 °C / 104°F max. Do NOT exceed this temperature. If the gas inlet temperature is

1.6 Intended use

The VDL vacuum drying ovens are suitable for drying and heat treatment of solid or pulverized charging material, as well as bulk material, using the supply of heat under vacuum.

During this process, the contained solvent may be able to form an explosive mixture with air under normal conditions. Generation of an explosive atmosphere and its ignition are prevented in the VDL vacuum drying ovens by various safety measures. The drying temperature with standard safety factor must lie below the ignition temperature and below the sublimation point of the charging material.

The temperature class of the inner chamber according to IEC 60079-14 can be T1, T2, or T3. Insert only substances with an ignition temperature that is higher than 135 °C / 275°F. The unit is not suitable to dry substances with an ignition temperature below 135 °C / 275°F. Substances falling under ignition group IIC are not permitted (e.g. carbon disulfide, hydrogen).

The VDL vacuum drying ovens are NOT suitable for the heat treatment of hazardous dusts or fibrous materials, which tend towards exothermal decomposition, or for materials that come under the legal definition of explosives. Dangerous chemical reactions must not occur during the drying process.

Following the instructions in this operating manual and conducting regular maintenance work (chap. 16) are part of the intended use.

The charging material shall not contain any corrosive ingredients that may damage the machine components made of stainless steel and aluminum. Such ingredients include in particular acids and halides. Any corrosive damage caused by such ingredients is excluded from liability by BINDER GmbH.

2. Description of the equipment

The VDL vacuum drying oven has been inspected by the TÜV Product Service GmbH in accordance with all safety-relevant guidelines and bears the TÜV-Mark P mark. Consequently, it is also expressly approved for drying materials with unlimited quantities of organic solvents.

The regular model is equipped with an explosion proof inner chamber. The Ex classification of inner chamber according to ATEX Directive 94/9/EC is

protection on the type plate determines the classification. Maximum temperature of the inner surfaces: 320 °C / 608°F. The temperature class of the inner chamber acc. to IEC 60079-14: depends on the setting of the tempera-

ture safety device and can be T1, T2 or T3. The temperature class of the entire unit equals the temperature class of the inner chamber.

All functions of the multifunctional program control can be set simply and conveniently via the easy to understand function keypad of the RD3 temperature program controller. This controller is equipped with touch function keys and a digital display and permits exact temperature setting and programming temperature cycles. The VDL provides almost unlimited possibilities of adapting to individual customer requirements based upon extensive programming options and on the week program timer and real time clock of the controller.

II -3G IIB T3-T1 Gc X. The description of explosion

The inner chamber is made of especially corrosion resistant stainless steel V4A (German material no.

1.4404 2B, US equivalent AISI 316L) micro-polished. The rack holder and all of the unit's vacuum connections and valves are made of especially corrosion resistant stainless steel V4A (German material no.

1.4571, US equivalent AISI 316Ti). The housing is RAL 7035 powder-coated. All corners and edges are also completely coated. When operating the chamber at temperatures above 150 °C / 302°F, the impact of the oxygen in the air may cause discoloration of the metallic surfaces (yellowish-brown or blue) by natural oxidation processes. These colorations are harmless and will in no way impair the function or quality of the unit.

The vacuum drying ovens in the APT.line™ are jacket-heated. The APT.line™ preheating chamber technique ensures a completely homogeneous jacket temperature, ensuring uniform heat transfer into the inner chamber. The low-loss heat transfer to the material uses the patented aluminum vacuum expansion racks (or optionally available in stainless steel V4A, 1.4571). The elastic-mounted safety glass window reliably compensates any overpressure or explosions that may occur. The additional polycarbonate panel ensures proven and effective splinter protection in the event of an implosion.

All VDL units provide an inert gas connection, a compressed air connection for sweeping the area for electrical equipment, and a measuring connection serving to connect a measuring access port.

The VDL vacuum drying oven is equipped with a serial interface RS 422 for computer communication, e.g. via the communication software APT-COM™ 3 DataControlSystem (option, chap.15.6). For further options, see chap. 19.3.

All installable items, such as racks and rack holders, can be easily removed. The completely smooth inner chamber with its rounded corners and internally welded seams is easy to clean.

The minimum working temperature of the VDL vacuum drying oven is approx. 15 °C / 27 °F above room temperature. The maximum temperature is 200 °C / 392°F.

Vacuum pumps with a suction capacity of 1 m The permissible end vacuum is 10

2.1 Safety equipment

• Pressure control device The VDL vacuum drying oven is equipped with a pressure control device with atmospheric pressure

compensation and has a set switch point of 125 ± 25 mbar / 3.69 ± 0.74 inHg). In the event of malfunction, some procedures would become an ignition source. Due to monitoring by the pressure control device such actions will only initiate if the pressure in the drying chamber is not higher than 125 ± 25 mbar / 3.69 ± 0.74 inHg.

The heating is released when a vacuum of 125 ± 25 mbar / 3.69 ± 0.74 inHg) or below is obtained. It will activate only then.

• Safety device class 2 This safety device protects the VDL vacuum drying oven, its environment and the charging material

against impermissible excess temperatures. When correctly set to the maximum permissible drying temperature it prevents exceeding the maximum drying temperature in case of a fault (chap. 12).

• Sweeping the area for electrical equipment and the preheating chamber with compressed air The area for electrical equipment and the preheating chamber are protected against explosion by a

technical ventilation system, which reliably prevents the penetration of explosive atmosphere to electrical or electronic parts of the VDL safety vacuum drying oven (protection against solvent-containing ambient air).

• Flame protection gasket In case of an explosion, the flame protection gasket prevents any flames from emerging directly

through the door gap..

4. Installation and connections

4.1 Vacuum expansion racks

The low-loss heat transfer to the material occurs via the patented aluminum vacuum expansion racks (also available in stainless steel as an option). The strong tension causes the racks to fit tightly against the interior wall and their largesurface contact area ensures rapid and effective heat transfer.

The removable rack holders allow for easy positioning. You can also remove the expansion racks for easy cleaning.

Do not remove them too often in order to prevent wear.

Figure 12: Using the expansion racks

• Pushing the locking lever: The expansion rack is released and can be removed.

• Pulling the locking lever: The expansion rack is pressed against the inner chamber walls.

Following each new tightening of an expansion rack, check that the lateral parts of the rack fit closely over their whole surface to the inner chamber wall. This is necessary in order to ensure the specified temperature exactitude.

For this purpose, the vacuum connection (13) with small flange DN16 must be connected to the back of the unit at the top with the vacuum pump or domestic vacuum system via a vacuum suction hose. For connecting to the unit, BINDER recommends the connection kits VP4 (Art. no. 8012-0621) or VP5 (Art. no. 8012-0622), (chap. 15.1).

With the option “stainless steel tubing” between the vacuum oven and vacuum module, the vacuum connection is already located inside the vacuum module.

Vacuum pumps with a suction capacity of 1-30 m³/h are suitable for the VDL vacuum drying oven. Permissible end vacuum: 10

For use of vacuum pumps in the European Union, note the following points:

• Pertaining to units that will be operated in potentially explosive areas, the requirements of ATEX Di-

rective 94/9/EC have to be met as of July 1, 2003.

• If combustible solvent will be introduced into the inner chamber, the vacuum pump must be construct-

ed in a suitable explosion-proof manner. The mixtures extracted from the drying chamber must be carried away making sure that there is no danger by ignition of these atmospheres. Otherwise use flame arresters.

Follow the safety instructions of the pump manufacturer.

In case of an explosion, the flame may be suctioned into the in-house vacuum system and result in further explosions.

DANGER

Danger due to flame flash-through with in-house vacuum system.

Danger of death.

 We recommend installing a flame arrester (flame flash-through barrier) according to EN

12874 between the vacuum drying oven and the in-house vacuum system.

For installing a flame arrester, please contact the BINDER INDIVIDUAL team. In the event of an error, sparking in the pump motor or the switching elements, electrostatic discharges,

as well as hot pump parts can ignite solvent vapors. Minimize this risk by using an ATEX (Directive 94/9/EC) compliant vacuum pump suitable for suction from Zone 0 or 1 and, if appropriate, from the zone of its installation site.

Connect the inert gas supply to the inert gas connection (adapter with hose olive diameter 8 mm / 0.31 in) via a pressure reducer. Screw the enclosed adapter with hose olive on the thread (11) at the unit rear. Set the pressure reducer to a pressure slightly above ambient pressure. Make sure that the pressure reducer will open. Do not alter this setting in order to avoid perturbation inside the oven and the release of large quantities of inert gas after flooding the VDL.

CAUTION

Overpressure in the inner chamber.

Turbulence of the charging material.

∅ Do NOT modify the atmospheric pressure setting.

4.4 Compressed air / inert gas connection for sweeping the area for electrical equipment

The compressed air flows through the area for electrical equipment as well the preheating chamber, which prevents a possible concentration of a solvent-containing atmosphere in the area for electrical equipment. You can alternatively connect inert gas or nitrogen to the compressed air connection. Use only dry gas.

In order to avoid that any oil coming from the compressed-air piping enters the vacuum drying oven, the compressor of the compressed air system must be equipped with an oil separator, or the compressed air system must be constructed oil-free. The condensate separator of the compressed air connection separates water and soil from the compressed-air piping, thus leading to compressed air quality class 4 acc. to ISO 8573-1. However, it does not prevent oil penetrating from the compressed air system, e.g. the compressed air compressor, into the compressed-air piping. The condensate separator is equipped with a manual condensate outlet (chap. 16.1).

air unit must be connected on the right side of the unit (hose olive ∅ 8 mm) to a compressed air line (compressed air system) or to an inert gas supply. There must be an overpressure of at least 1.5 bar / 44.3 inHg in the supply network. The maximally permitted pressure is 7 bar / 206.7 inHg.

Immediately after connecting the compressed air or inert gas supply, the area for electrical equipment of the oven will be swept at 5 liters per minute. This air or inert gas quantity is used and then released into the surrounding atmosphere permanently; compressed air or inert gas connection on the building side should be equipped with a stop valve that can be used to cut off the gas supply, after having operated the drying oven.

If solvent-containing air penetrates the electrical area of the unit, explosions may result.

VDL (E2.1) 04/2014 page 38/107

Explosion hazard.

∅ Do NOT take the air for the compressed air supply from explosive atmospheres.

If the unit is not connected to the compressed air supply, or if the specified overpressure is not reached, it is impossible to start the VDL vacuum drying oven.

4.5 Electrical connection

• The VDL vacuum drying oven comes with a fixed power connection cable that has a length of 1800

mm / 5.9 ft. and a shockproof plug. The socket must also provide a protective conductor.

• Unit fuse 10 Amp

• Power supply voltage 230 V (1N~) ± 10 %, 50/60 Hz

• Prior to connection and start-up, check the power supply voltage. Compare the values to the specified

data located on the unit’s type plate (left side of the unit, bottom right-hand, chap. 1.4).

• When connecting, please observe the regulations specified by the local electricity supply company as

well as the VDE directives (for Germany)

• Pollution degree (acc. to IEC 61010-1): 2

• Over-voltage category (acc. to IEC 61010-1): II

CAUTION

Danger of incorrect power supply voltage. Damage to the equipment.

 Check the power supply voltage before connection and start-up.  Compare the power supply voltage with the data indicated on the type plate.

DANGER

Solvent-containing air penetrating and concentration in the electrical area of the unit.

Explosion hazard.

 Before turning on the unit via the key switch (1), sweep the area for electrical equipment

at least 15 minutes with compressed air or inert gas. Sweeping the area for electrical equipment must take place during the entire operation, as otherwise the VDL vacuum drying oven will shut off at all poles.

After connecting the supply lines (chap 4) and checking all safety instructions and conditions of installation and safe operation, turn on the unit via the key switch (1):

• Position 0: Oven is not operating

No consumption of compressed air or inert gas in the area for electrical equipment. If the fine dosage valve (6) is open, inert gas may be used and can reach the ambient air.

• Position I: Oven is operating

If no indication appears in the display of the program controller RD3, the compressed air supply is probably not properly connected.

Warming chambers may release odors in the first few days after commissioning. This is not a quality defect. To reduce odors quickly we recommend heating up the chamber to its nominal temperature for one day and in a well-ventilated location.

5.1 Settings at the RD3 program controller

After turning the unit on with the key switch (1) the controller is in Normal Display / Fixed value operation mode.

8. Program editor

8.1 Selecting between set-point ramp and set-point step

You can program various kinds of temperature transitions. In the user level (chap. 10) you can select between the settings “Ramp” (default setting) and “Step”.

Setting “Ramp” allows programming all kinds of temperature transitions. With setting “Step” the controller will equilibrate only to constant temperatures; programming

ramps is no longer possible.

Switching between settings “Ramp” and “Step” will influence all programs. Please note that this can cause the time courses of existing programs to change significantly.

8.1.1 Programming with setting “Ramp” (default setting)

Set-points always refer to the start of a program section, i.e., at the beginning of each program section, the entered set-point is reached. During program section operation, the temperature gradually passes to the set-point entered for the subsequent program section.

You can program all kinds of temperature transitions by the appropriate design of the program section timing:

• Gradual temperature changes “set-point ramp“

The set-point gradually moves from one set-point to the one of the following program section during a given interval. The actual temperature value (X) follows the continually moving set-point (W) at any time.

Temperature ramps can be programmed in order to extend the heating up times. This may be necessary in order to avoid temperature stresses in the material during the heating up phase. Heating up times can be considerably slowed down by the use of temperature ramps.

• Program sections with constant temperature

The initial values of two subsequent program sections are identical; therefore the temperature remains constant during the whole time of the first program section.

• Sudden temperature changes “set-point step”

Steps are temperature changes (ramps) that occur during a very short interval. Two program sections with an identical set-point are followed by a section with a different set-point. If the duration of this transitional program section is very short (minimum entry 1 min), the temperature change will proceed rapidly in the minimum amount of time.
