Ammonia Compressor Lubricants
NEXT Lubricants supplies compressor lubricants for industrial ammonia (R717) refrigeration systems, covering screw and reciprocating compressor types across cold storage, food processing, freezing, dairy and industrial cooling applications. Product selection is based on compressor type, operating temperature range and system design.
Knowledge
Lubrication Considerations for Ammonia Refrigeration
Ammonia (R717) has specific characteristics that directly influence compressor lubricant selection. Understanding these factors helps identify the right product for your system.
Refrigerant Miscibility
Ammonia (R717) has very low miscibility with most lubricant types. Lubricant selection must account for this to support effective oil separation and control oil circulation through the refrigerant circuit.
Low Temperature Fluidity
Ammonia systems can operate at evaporating temperatures well below -40°C in two-stage configurations. Lubricant pour point and low-temperature viscosity must be matched to the low-side conditions of the specific installation to ensure oil return and adequate bearing protection.
Discharge Temperature Stability
At the compression ratios typical of industrial ammonia systems — particularly in single-stage operation at low evaporating temperatures — compressor discharge temperatures can be elevated. Lubricant thermal stability at these conditions influences oil service life and deposit formation risk.
