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. OW4 OilWatch is a monitoring system without active oil balancing, providing alarm indication and compressor cut-off. They are for use with HCFC and HFC refrigerants, CO2, mineral, synthetic and ester oils. Maximum allowable pressures (PS): OM3: 35 bar. OM4/OW4: 60 bar.
- Acid test kit (AOK) is a quick and easy way to check the acid number of refrigerant oils.
