M&M Refrigeration/Sabroe reciprocating compressors are all heavy duty compressors designed for the toughest industrial and marine applications. Suitable for most refrigerants, including HCFC, HFC, hydrocarbons, ammonia, and carbon dioxide, they are well-proven, safe, and reliable. The basic design concept was introduced in 1954. All subsequent design improvements are compatible with early compressor models — a feature which ensures that older compressors can be upgraded to the latest design with improved efficiency.

This process of continuous research and development has resulted in a product line which is superior to any competitor in the market with regard to:

• Compressor range
• Flexibility
• Reliability
• Operating efficiency
• Environmental safety
• Operating safety
• Maintenance
