INTRODUCTION
The main use of the oil separator is in the refrigeration systems, with the goal to separate lubricating oil
from refrigerant after compressor discharge; oil concentration reduction guarantees maintaining chiller
performance.
The main use of liquid receiver is to store liquid refrigerant, according to the load required by the evaporator.
Furthermore, it ensures that expansion valve is feeded with only liquid refrigerant, working as trap for non-
condensable.
The standard construction materials of PROVIDES oil receivers and tank consist in: carbon steel for header,
shell and refrigerant connections and support brackets.
On request other materials can be used.
3. Refrigerants
It is possible to use HCFC, HFO, HFC, NH3 and propane and others provided they are compatible with
construction materials and certification.
