Danger of death.
∅ Do NOT operate the chamber in potentially explosive areas.
KEEP explosive dust or air-solvent mixtures AWAY from the chamber.
The vacuum drying ovens were constructed in accordance with the applicable VDE regulations and were
routinely tested in accordance with VDE 0411-1 (IEC 61010-1). The production underlies an internal
monitoring according to ATEX Directive 2014/34/EU appendix VIII.
For the user there is no risk of temporary overvoltages in the sense of EN 61010-1:2010.
Even when the equipment is used properly, there exists a residual risk of explosion that cannot be excluded, particularly in relation to the environment of the chamber. To minimize this risk, strictly observe
the legal regulations about how to select an appropriate location.
DANGER

through barrier) according to EN
1.5.2 Safety instructions on vacuum supply
Within the European Union, units that will be operated in potentially explosive areas have to meet the
requirements of ATEX Directive 2014/34/EU.
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.
DANGER
Danger due to flame flash-through with in-house vacuum system.
Danger of death.
We recommend installing a flame arrester (flame flashISO 16852:2010 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
2014/34/EU 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 2014/34/EU 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 2014/34/EU 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.
VDL (E2.1) 05/2016 page 11/108
The ATEX Directive 2014/34/EU compliant pumps offered by BINDER provide an integral
protective device.
The ATEX Directive 2014/34/EU 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.
The ATEX Directive 2014/34/EU 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.
1.5.3 Safety 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 chamber 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.

∅ The ignition temperature of the contained solvents must NEVER be reached. For safety
reasons, you must provide a safety gap.
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 chamber
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” (
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 ex-

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 VDL vacuum drying oven is explicitly approved for drying of materials with unlimited amounts of organic solvents. The VDL is equipped with an explosion-proof inner chamber.
The temperature class of the inner chamber according to IEC 60079-14 can be T1, T2, or T3. It depends
on the maximum operation temperature inside the oven. Depending on the ignition temperature of the
flammable substance, this temperature and can be adjustably set on the temperature safety device according to the “Temperature setting” information panel (chap. 2.5).
Insert only substances with an ignition temperature that is higher than 135 °C / 275 °F. The chamber 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. Such substances must not be introduced into the oven. Dangerous chemical reactions must not occur during the drying process.
VDL vacuum drying ovens are not suitable for use in conjunction with explosive dust atmospheres or
hybrid mixtures.
Do not use the week program timer when using explosive substances.
Other applications are not approved.
The chambers are not classified as medical devices as defined by the Medical Device Directive
93/42/EEC.
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 2014/34/EU is
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 chamber 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 real time clock of the controller.
II -/3G c IIB T3-T1 Gc X. The description of
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 chamber'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 chamber.
The vacuum expansion racks allow for low-loss heat transfer to the material. The strong tension causes
the racks to fit tightly against the interior wall and their large-surface contact area ensures rapid and effective heat transfer.
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 chambers 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.

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 penetration of
explosive atmosphere by a technical ventilation system (1.8 bar overpressure). This is monitored by a
pressure sensor with a fixed switching threshold. Pressure loss results in turning off the entire oven.
This reliably prevents explosive atmosphere to reach 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..
