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 or-
ganic 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 ac-
cording 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 defi-
nition of explosives. Such substances must not be introduced into the oven. Dangerous chemical reac-
tions 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 ma-
chine components made of stainless steel and aluminum. Such ingredients include in particu-
lar acids and halides. Any corrosive damage caused by such ingredients is excluded from
liability by BINDER GmbH.
