Danger of death.
∅
Do NOT introduce any substance into the oven which is combustible or explosive at
working temperature.
∅NO explosive dust or air-solvent mixture in the inner chamber.
∅Do NOT use the vacuum
drying oven for drying or heat treatments leading to release of
combustible vapors able to form an explosive mixture with air.

VD (E2.1) 07/2017 page 10/96
Any solvent contained in the charging material must not be explosive or inflammable. I.e., irrespective of
the solvent concentration in the steam room, NO explosive mixture with air must form. The drying
temperature must lie below the flash point or below the sublimation point of the charging material.
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.
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 chamber into operation.
DANGER
Electrical hazard.
Danger of death.
∅The oven must NOT become wet during operation or maintenance.
The chambers were produced in accordance with the relevant VDE regulations and were routinely tested
in accordance to VDE 0411-1 (IEC 61010-1).
During and shortly after operation, the temperature of the inner surfaces almost equals the set-point.
CAUTION
The inner chamber will become hot during operation.
Danger of burning.
∅Do NOT touch the inner surfaces or the charging material during operation.
In the case of operation with inert gas, the chamber is supplied with an oxygen-displacing gas (e.g. N2).
The gas emerging from the system must therefore be removed from the installation area by means of a
suitable extraction system (see technical ventilation measures in the DGUV guidelines 213-850 on safe
working in laboratories (formerly BGI/GUV-I 850-0, BGR/GUV-R 120 or ZH 1/119, issued by the
employers’ liability insurance association) (for Germany).
With use of a vacuum system or a vacuum pump, observe the permitted gas inlet
temperature. Observe the safety instructions of the pump manufacturer.

VD (E2.1) 07/2017 page 11/96
1.6 Intended use
The VD 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. The solvent content must not
be explosive or flammable. A mixture of any component of the charging material with air must NOT be
explosive. The drying temperature must lie below the flash point or below the sublimation point of the
charging material. Any component of the charging material must NOT be able to release toxic gases.
Other applications are not approved.
The chambers are not classified as medical devices as defined by the Medical Device Directive
93/42/EEC.
Observing the instructions in this operating manual and conducting regular maintenance work
(chap. 17) is 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.
DANGER
Explosion or implosion hazard.
Danger of poisoning.
Danger of death.
∅Do NOT introduce any substance combustible or ex
plosive at working temperature into
the chamber, in particular no energy sources such as batteries or lithium-ion batteries
∅NO explosive dust or air-solvent mixture in the inner chamber.
∅Do NOT introduce any substance which could lead to release of toxic gases.
In case of foreseeable use of the chamber there is no risk for the user through the integration of the
chamber into systems or by special environmental or operating conditions in the sense of EN 61010-
1:2010. For this, the intended use of the chamber and all its connections must be observed.

VD (E2.1) 07/2017 page 12/96
2. Description of the equipment
Vacuum drying is used for special drying problems, for which conventional drying methods cannot offer a
solution due to physical limitations.
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 VD 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 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 chambers 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). 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 VD chambers provide an inert gas connection and a measuring connection serving to connect a
vacuum controller or a measuring access port.
The chambers are equipped as standard with a large-surface safety valve. The toughened safety glass
window is elastic-mounted and in the event of explosion serves as a safety valve. The additional plastic
panel provides splinter protection.
The chambers are equipped with a serial interface RS 422 for computer communication, e.g. via the
communication software APT-COM™ 3 DataControlSystem (option, chap.16.8). For further options, see
chap. 20.3.
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 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 VD vacuum drying oven.
The permissible end vacuum is 10-2 mbar / 0.0003 inHg.

temperature and is completely dry.
3.4 Location of installation and ambient conditions
Set up the VD vacuum drying oven on a flat, even, and non-flammable surface, free from vibration, in a
well-ventilated, dry location. Align it using a spirit level. The site of installation must be capable of
supporting the chamber’s weight (see technical data, chap. 20.2). The chambers are designed for setting
up inside a building (indoor use).
CAUTION
Danger of overheating.
Damage to the chamber.
∅Do NOT set up chambers in non-ventilated recesses.
Ensure sufficient ventilation for dispersal of the heat.
•Permissible ambient temperature range during operation: +18 °C / 64°F to +32 °C / 90°F.
The ambient temperature should not be substantially higher than the indicated ambient
temperature of +25 °C / 77°F to which the specified technical data relate. Deviations from the
indicated data are possible for other ambient conditions.
•Permissible ambient humidity: 70 % r.H. max., non-condensing.
•Installation height: max. 2000 m / 6562 ft above sea level.

VD (E2.1) 07/2017 page 18/96
When placing several chambers of the same size side by side, maintain a minimum distance of 250 mm /
9.8 in between each chamber. Wall distances: rear 100 mm / 3.9 in, sides 135 mm / 5.3 in. Spacing
above and behind the chamber of at least 100 mm / 3.9 in must also be maintained.
CAUTION
Danger by stacking.
Damage to the chambers.
∅Do NOT place vacuum drying ovens on top of each other.
To completely separate the chamber from the power supply, you must disconnect the power plug. Install
the chamber in a way that the power plug is easily accessible and can be easily pulled in case of danger.
For the user there is no risk of temporary overvoltages in the sense of EN 61010-1:2010.
Do not install or operate the vacuum drying oven VD in potentially explosive areas.
DANGER
Explosion hazard.
Danger of death.
∅Do NOT operate the chamber in potentially explosive areas.
KEEP explosive dust or air-solvent mixtures AWAY from the vicinity of the chamber.
The maximum permissible ambient temperature of the vacuum pumps delivered by BINDER is 40 °C /
104°F.
Notes when using inert gas:
When operating the VD vacuum drying oven with inert gas, correctly follow the technical ventilation
measures, as described in the DGUV guidelines 213-850 on safe working in laboratories (formerly
BGI/GUV-I 850-0, BGR/GUV-R 120 or ZH 1/119, issued by the employers’ liability insurance association)
(for Germany).
For operation with inert gas, the chamber 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 O2content 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 chambers 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
valves (4) or (6).

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 large-
surface 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 7: 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.
CAUTION
Invalid calibration.
∅Do NOT change between aluminum and stainless steel racks
Use the delivered expansion racks only
4.2 Vacuum connection
Always connect the VD vacuum drying oven to a vacuum pump or to a domestic vacuum system. For this
purpose, the vacuum connection (13) with small flange DN16 must be connected to the back of the
chamber at the top with the vacuum pump or domestic vacuum system via a vacuum suction hose. For
connecting to the chamber, BINDER recommends the connection kit VD, Art. no. 8012-0146.
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 VD vacuum drying
oven. Permissible end vacuum: 10-2 mbar / 0.0003 inHg.
4.3 Inert gas connection
When operating the VD vacuum drying oven with inert gas, correctly follow the technical ventilation
measures, as described in the DGUV guidelines 213-850 on safe working in laboratories (formerly
BGI/GUV-I 850-0, BGR/GUV-R 120 or ZH 1/119, issued by the employers’ liability insurance association)
(for Germany).
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 (12) at the chamber
rear. Set the pressure reducer to a pressure slightly above ambient pressure. Ensure that the pressure
reducer will certainly open. Do not alter this setting in order to avoid perturbation inside the oven and
release of big quantities of inert gas after flooding the VD.
