When it comes to managing refrigeration systems, one of the main concerns is to keep the compressor lubricated while maintaining a high level of heat transfer and energy efficiency by removing as much oil as possible from the refrigerant. This requires sophisticated oil management devices.

Emerson Climate Technologies' oil controls monitor oil levels throughout the refrigeration systems. The line includes:

• Oil Separators (OS.Series) remove the oil from the gaseous refrigerant coming from the compressors outlet. 
• Oil Level Management Systems (OM3/OM4) check the oil level in the compressor’s crankcase and control refill of oil through a built-in solenoid valve. They are for use with HCFC, HFC, mineral, synthetic and ester oils. Maximum allowable pressures (PS): OM3: 31 bar. OM4: 45 bar.
• Acid test kits (AOK) is a quick and easy means to check refrigerant oil for access acid.
