MULTI REFRIGERANTS CORE SENSE Multi Refrigerant One Compressor - Multiple Applications At Best Efficiency SOUND Today’s most commonly used refrigerant is R404A. Improving system architectures, changing compressor technology or moving to a refrigerant with a lower Global Warming Potential (GWP) can significantly improve the carbon footprint of an installation. Efficiency Comparison Moving from R404A to R134a is one of many ways to reduce the GWP (from 3922 to 1430). While this requires a compressor of bigger displacement for the same capacity, the GWP is reduced by 64% and the system’s...

Modulation SOUND One Compressor - Two Modulation Options There is a common goal shared by many in refrigeration: preserve and display food at safe temperatures and reasonable operating cost. Varying the capacity available to meet the load is the most significant way to achieve this objective. This ability leads to a more stable temperature in the refrigerated areas and does so at favorable power consumption since producing excess capacity is avoided. What It Means To You All Stream compressors are released for applications using inverter technology. In addition, and in an effort to give...
