Central receiver for refrigerant oil from the entire refrigeration system.
The WITT HDB can be used in different ways:
When used as an oil receiver the HDB3 does not require insulation, as the ambient heat is used to evaporate remaining liquid refrigerant. If the ambient temperature is not sufficient, an electric heating element can be mounted via the existing thermowell. Manual oil draining is executed via a combination of service stop valve and quick acting valve (dead man valve) WITT SSV6.
When used as a distribution vessel the HDB3 is used in an automatic oil management system in combination with the oil recovery unit (BDP) to distribute the returned refrigerant oil throughout several compressors.
When the HDP3 is used as supplementary oil dome it acts as a pre-collector in an automatic oil return system.
The HDB3 stainless steel oil receiver is manufactured in accordance with AD2000 and the Pressure Equipment Directive. It comes with all required connections, i.e. level control or optional oil sensor.
The HDB3 stainless steel oil collector consists of:
