Saying that it offers an efficient solution for demanding refrigeration applications, with its unique scroll design and manufacturing process flexibility, Danfoss has released its new range of MLZ Refrigeration Compressors. The series includes 11 models of medium temperature scroll compressors designed for commercial refrigeration applications.

According to Danfoss, the compressors are purpose-engineered for refrigeration, and offer customers the possibility to specify cooling capacities from 3,800 to 30,000 watts and to select from global voltages and frequencies as well as any of the common refrigerants (404A/134a/507/22). The MBP scroll compressor range will complement the company’s existing line of MT/LT hermetic reciprocating compressors, condensing units and package units, and will be available in compressor, condensing unit, and package unit designs.

The manufacturer claims that the compressors reduce overall costs in the following manner:

• The hybrid-wrap scroll design will reduce energy cost in normal operating conditions and deliver high capacity and an optimised pressure ratio for refrigeration applications.
• In varying cooling cycles (such as ice machines or during pull down), the Danfoss patented Adaptive Control system Danfoss ensures that the scrolls will have continuous optimum axial pressure, thus reducing leakage, while minimising friction.
• A patented overload protection system will reduce the system’s down time.
• Its multi-refrigerant smaller and lighter design and local/global availability will help reduce installation costs.
• Reduced noise due to a check valve design translates into less cost for lownoise applications.
