BDP
Oil recovery unit
Automatic oil return using hot gas.
The WITT BDP oil recovery unit is collecting the refrigerant oil before it is returned via hot gas back to the compressor. This way valuable refrigerant oil is re-used and remains in the refrigeration cycle.
Re-using the refrigerant oil eliminates the need to drain it manually, as such avoiding associated accidents. In addition the refrigerant oil recovery safes operating costs (maintenance, oil disposal, oil-refill) and protects the environment.
We offer with the BDP a proven, standardised solution. The housing is designed for up to 40 bar and can be opened for easy access.
The optional oil sensor enables a demand controlled oil return.

ATEX
The BDP2 without optional level sensor has no ignition sources and therefore it does not meet the definition of
devices according to the ATEX Directive 94/9 / EC.
The basis for this is an risk assessment of ignition sources according EN 13463-1, chapter 5.2. Even during possible occurring malfunctions there are no own potential ignition sources present.
