BINDER VD 23 - Manual (Page 17)

VDL (E2.1) 04/2014 page 17/107
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 tempera-
ture.
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 intro-
duce 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 pro-
cess, 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.
