The task of the helical oil separators is to separate oil from the discharge refrigerant correctly and ensure oil return to the compressor most effectively. The purpose is maintaining crankcase oil level and increasing the efficiency of the system by minimizing the excessive oil circulation. Helical oil separators are designed for high pressure oil management systems, they can be used in various systems and multiple compressors. The products are designed for use with scroll and piston compressors, they are not recommended for screw or rotary vane compressors.
