Pertaining to units that will be operated in potentially explosive areas, the requirements of ATEX Directive 94/9/EC have to be met as of July 1, 2003.

If combustible solvent is introduced into the drying chamber, the vacuum pump must be constructed in a suitable explosion-proof manner.

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 concentrations. 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 currentdependent, 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 too high and then becomes even warmer by compression in the pump, the resulting temperature (of the gas-solvent mixture inside the pump) could exceed the solvent’s temperature class and ignition temperature.

DANGER

Exceeding the gas inlet temperature.

Exceeding the ignition temperature of the solvent.

Risk of ignition and explosion.

Damage to the vacuum pump.

Danger of death.

Do NOT exceed a set-point temperature of 40 °C / 104 °F.

With set-point temperature > 40 °C / 104 °F, take appropriate measures to cool down the extracted vapor before it enters into to the vacuum pump.

1.5.3Safety instructions on the charging material

The temperature class of the inner chamber according to IEC 60079-14 can be T1, T2, or T3. Only introduce substances with an ignition temperature that is higher than 135 °C / 275°F. You can use a solvent which would form an explosive mixture with air under normal conditions.

This 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).

DANGER

Inappropriate charging material.

Explosion hazard.

Danger of death.

Do NOT introduce any substance with an ignition temperature below 135 °C / 275 °F into the oven.

Do NOT introduce hazardous dusts or fibrous materials, which tend towards exothermal decomposition into the oven.

Do NOT introduce materials that come under the explosive substance law into the oven.

If the ignition temperature of a solvent contained in the drying material is exceeded during the drying process, there is an immediate risk of fire and explosion.

DANGER

Formation of explosive solvent-air mixtures.

Fire and explosion hazard.

Danger of death.

The ignition temperature of the contained solvents must NEVER be reached. For safety reasons, you must provide a safety gap.

VDL (E2.1) 04/2014

page 17/107

If the following precautions are not followed, the vapors resulting from heating of the solvent can ignite on the hot walls of the inner chamber.

Required measures:

• The maximum drying temperature is a result of the lowest ignition temperature of the introduced solvent or solvent mixture. Take the ignition temperature from the safety specifications of the solvent. Determine the maximum drying temperature according to the information panel “Temperature setting” (chap. 2.5) on the unit front. Do NOT exceed this temperature when presetting the set point on the RD3 temperature controller.

•Before starting the drying process, set the temperature safety device to the maximum allowed drying temperature according to the information panel “Temperature setting” (chap. 2.5). This will ensure that even in the event of error or an incorrect increase of the temperature set point on the RD3 controller the maximum permissible drying temperature is not exceeded. It is NOT sufficient to directly adjust the maximum temperature of the temperature safety device to the maximum temperature of the solvent’s temperature class.

•During the drying process, use only those solvents for which the temperature setting has been performed.

•In the case of solvent mixtures, use the ignition temperature of the material with the lowest ignition temperature. For the correct ignition temperature, refer to the safety specifications of the solvent.

•Let the oven cool down to ambient temperature before you start a new drying process with a modified ignition temperature.

Familiarize yourself with the physical and chemical properties of the charging material, as well as the contained moisture constituent and its behavior with the addition of heat energy and changes in pressure. No dangerous chemical reactions must occur during the drying process.

Familiarize yourself with any potential health risks caused by the charging material, the contained moisture constituent or by reaction products that may arise during the drying process. Take adequate measures to exclude such risks prior to putting the VDL vacuum drying oven into operation.

1.5.4 Safety instructions on operating the vacuum drying oven

Note the following points before starting up the oven:

• When loading the unit and possibly at the moment of removal, also in the context of intended use, an explosive mixture may form in the working space. Define a safety area of at least 1m from the unit front.

•Ensure that at no time any solvent vapors could enter in the area of the electrical installation room and the operating panel.

•Provide additional security measures in the area of the vacuum pump stand, particularly in the areas of the glass flask (when emptying it) and the exhaust air of the vacuum pump.

•The accessible area in front of the equipment must be designed conductive. Provided cyclic measurements.

•The personal protective equipment (PPE) of the operating personnel must be implemented ESD protected.

VDL (E2.1) 04/2014

page 18/107

DANGER

Electrical hazard. Danger of death.

The oven must NOT become wet during operation or maintenance.

CAUTION

The inner chamber will become hot during operation. Danger of burning.

Do NOT touch the inner surfaces or the charging material during operation.

When operating the VDL vacuum drying oven with inert gas, correctly follow the technical ventilation measures, as described in the guideline BGI/GUV-I 850-0 on safe working in laboratories (formerly BGR/GUV-R 120 or ZH 1/119 laboratory guidelines issued by the employers’ liability insurance association) (for Germany).

Do not start up the unit without technical ventilation.

During operation with inert gas, the unit is supplied with an oxygen displacing gas (e.g. N2). Inert gases in high concentrations are hazardous to health. They are colorless and almost odorless and therefore practically imperceptible. Inhalation of inert gases can cause drowsiness up to respiratory arrest. When the O2 content of the air decreases below 18%, there is risk of death from lack of oxygen. Any gas that might escape has to be led out via good room ventilation or a suitable exhaust system.

WARNING

High concentration of inert gas.

Risk of death by suffocation.

Do NOT set up units in non-ventilated recesses.

Ensure technical ventilation measures.

Respect the relevant regulations for handling these gases.

When decommissioning the vacuum drying oven, shut off the inert gas supply: Close valve (6).

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

DANGER

Solvent-containing air penetrating the electrical area of the oven.

Explosion hazard.

Do NOT take the air, which will be used to supply the unit with compressed air, from a potentially explosive atmosphere.

Avoid the solvent accumulation in the vacuum module (option) as this would cause the vacuum module to become an explosive area (Zone 0 or 1 or 2). The VDL vacuum drying oven located on top of the module is not explosion-proof constructed in regards to its surroundings.

VDL (E2.1) 04/2014

page 19/107

DANGER

Operation with material containing solvent that may be able to form an explosive mixture with air.

Explosion hazard.

Follow the measures required for operation with solvent-containing materials that can form an explosive mixture with air.

Measures required for operation with solvent-containing materials that can form an explosive mixture with air:

•Only trained personnel with key-authorization can work on the VDL vacuum drying oven

•Sweep the area for electrical equipment with compressed air or inert gas for at least 15 minutes. Sweeping must take place during the entire operating cycle; otherwise the vacuum drying oven will shut off at all poles.

•Only after at least 15 minutes of sweeping, use the key switch to put the unit in operation.

•Determine the maximum drying temperature in relation to the ignition temperature of the solvent according to the information panel “Temperature setting” (chap. 2.5). Do NOT exceed this temperature when presetting the set point on the RD3 temperature controller.

•In the case of solvent mixtures, use the ignition temperature of the solvent with the lowest ignition temperature. For the ignition temperature, refer to the safety specifications of the solvent.

•Before starting the drying process, set the temperature safety device to the maximum allowed drying temperature according to the information panel “Temperature setting” (chap. 2.5). It is NOT sufficient to directly adjust the maximum temperature of the temperature safety device to the maximum temperature of the solvent’s temperature class.

•Introduce the drying material and turn on the vacuum pump.

•Start the drying process. The heating unit is only released when a vacuum of 125 ± 25 mbar / 3.69 ±0.74 inHg) or below is reached.

•The duration of the drying process can be determined by means of the analogue pressure display on the oven. When the pressure drops to pump pressure, the drying process is finished.

•Stop the drying process.

•Ventilate the vacuum drying oven using the aeration valve for ambient air (5) or inert gas

(6).

•Remove the charging material. Turn the key switch to position 0 (OFF) and remove the key to prevent unauthorized operation of the oven.

•Sweep the area for electrical equipment at least 15 minutes with compressed air or inert gas.

•Let the oven cool down to ambient temperature before you start a new drying process with a modified ignition temperature.

1.6Intended 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 II -3G IIB T3-T1 Gc X. The description of explosion 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 temperature 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.

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 m3/h to 30 m3/h are suitable for the VDL vacuum drying oven. The permissible end vacuum is 10-2 mbar / 0.0003 inHg.

VDL (E2.1) 04/2014

2.1Safety 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..

•Spring-mounted safety glass panel and splinter protection

The VDL vacuum drying oven is equipped with a large-surface area safety valve.

The inspection window, consisting of ESG glass (toughened safety glass), is spring-mounted and serves as a safety valve in the event of explosion. The additional plastic panel provides splinterprotection.

2.5“Temperature setting” information panel (ignition temperature vs. drying temperature)

Temperatureinstellung VDL

Adjustment of temperature VDL

This information panel is mounted to Ajustement de température VDL the door of the VDL vacuum drying

oven and shows the maximum permissible drying temperature depending on the ignition temperature of the solvent.

The reading graph reflects the fact that the inner chamber walls will become warmer than the expansion racks, especially during the heatingup phase, and will thereby exceed the set-point temperature.

Figure 9: Temperature setting information panel

You must observe the indicated safety margin between ignition temperature and drying temperature.

According to IEC 60079-14, you must introduce only substances with an ignition temperature which is higher than 135 °C / 275°F. This unit is NOT suitable to dry substances with an ignition temperature below 135 °C / 275°F.

If the ignition temperature of a solvent contained in the drying material is exceeded during the drying process, there is an immediate risk of fire and explosion.

DANGER

Exceeding the ignition temperature of a solvent.

Risk of fire and explosion.

Danger of death.

The ignition temperature of a contained solvent must NEVER be reached. For safety reasons, always ensure that there is a safety margin.

Required measures:

• Determine the maximum drying temperature in relation to the ignition temperature of the solvent in accordance with the “Temperature setting” information panel (chap. 2.5). Do NOT exceed this temperature when presetting the set-point temperature at the temperature controller RD3.

•Before starting the drying process, set the temperature safety device to the allowed maximum drying temperature according to the information panel “temperature setting” chap. 2.5), so that even in the event of error or incorrect increase of the temperature set-point on the RD3 controller the maximum permissible drying temperature is not exceeded. It is NOT sufficient to directly adjust the maximum temperature of the temperature safety device to the maximum temperature of the solvent’s temperature class.

•(continued)

VDL (E2.1) 04/2014
