RHA Series Synthetic Refrigeration Compressor Oils

RHA Series refrigeration compressor oils are highly refined, hydrotreated compressor oils specially designed to function under the stringent requirements of refrigeration systems. Besides providing value-added benefits in the areas of improved system efficiency and higher productivity, the performance advantages of RHA Series oils versus naphthenic oils include:

• Reduced oil carryover
• Superior cleanliness
• Superior chemical and thermal stability
• Enhanced wear protection
• Lower foaming tendency
• Extended oil drain interval capability
• Less oil make-up

RHA Series refrigeration compressor oils are exceptionally well-suited for rotary screw and reciprocating compressors in ammonia or R22 service. They are compatible with naphthenic and other hydrotreated paraffinic-based  compressor oils for similar service, as well as PAO and alkylbenzene-based  products. They are compatible with all seal elastomers commonly used in these  systems including Buna-N, NBR and Neoprene. RSHA-32A is suitable for HCHC refrigerants including R22. Please consult Simmons Synthetics representative on special requirements for special applications.

Benefits

• An ammonia refrigeration compressor oil designed for low temperature evaporator and refrigeration compressor applications.
• Formulated from highly refined hydrotreated paraffinic base stocks to provide performance advantages over naphthenic oils.
• RHA remains in the compressor and is not carried down stream with the ammonia into the cold side of the system where it can interfere with the cooling efficiency of the unit.
• Reduces power consumption by reducing friction and promoting system efficiencies.
• Lower foaming tendency.
• Excellent thermal and chemical stability.
• Reduced lubricant consumption and extended oil drain intervals.
• Improves cleanliness and system efficiency.

Recommended applications

• Rotary screw and reciprocating compressors for ammonia service.
• Can be used with R22.

Materials Compatibility

RHA Series refrigeration compressor oils are compatible with other hydrotreated paraffinics based compressor oils for ammonia and R22 service as well as all seal elastomers commonly used in these compressor types including H-NBR, M-NBR, Neopreme and Viton.
