The range of GVN OS.D oil separators designed for use in screw compressors. Oil separators are available with tank volume range from 50 to 550 litres, dedicated to refrigerants HCFC, HFC, R290 (propane), and R717 (ammonia). They can operate with a maximum working pressure (PS1) of 33 bar. They have been manufactured in accordance with the CE Directive 2014/68/EU [PED] concerning pressure equipment.
The purpose of oil separators for screw compressors is to properly separate oil from the discharged refrigerant and to ensure the most effective return of oil to the compressor. It is recommended to use a safety valve and an oil level sensor. Connections for the oil level sensor, oil heaters, and oil thermostat are available as standard on the oil separator.
GVN OS.D series oil separators are installed on the discharge line of screw compressors. They feature a two-stage housing design. The first part is the separation section, which functions to separate oil from the discharge gas coming from the compressor. The second part is the chamber section, which serves to collect the separated oil. At the outlet of the OS.D oil separators, a gas check valve is installed.
