Summit RPS Series are specially formulated polyalkylene glycol (PAG) synthetic ammonia compressor lubricants designed to function in ammonia refrigeration systems utilizing direct expansion (DX) evaporators and rotary screw compressors. Summit RPS Series is unique in its optimum miscibility with ammonia allowing easier oil return to the compressor with no oil accumulation inside the system. Minimal oil carryover guarantees improved thermal efficiency and productivity gains with reduced maintenance downtime.
In addition, Summit RPS Series offers superior lubricity and wear protection due to a high viscosity index, non-foaming characteristics and high chemical stability in the presence of ammonia.
