Environmental impact and energy consumption is at the center of every discussion relating to sustainable refrigeration. Retailers face important challenges as they strive to find the right balance between ecological and economical aspects. Therefore energy efficiency is always under scrutiny as it impacts both the carbon footprint and the costs relative to an installation. Conventional Compressor With “Reed” Valve Technology Stream Compressor With Discus™ Valve Technology By leveraging and improving the Discus valve technology, the new Stream features a series of design characteristics that...

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...

Modulation SOUND Our Digital Technology - Your Benefits Apart from these benefits digital modulation offers significiant additional advantages as described to the right. Features & Benefits êê o specific precautions are necessary with respect N to oil return as Stream Digital runs at constant speed just like a standard compressor Noise Emissions - A Serious Concern Cycle Time The compressor capacity is controlled by modulating the solenoid valve input over time. Example 1 : •  Cycle time: 20 sec •  Valve active/open: 10 sec •  Valve inactive/closed: 10 sec •  Resulting capacity: 50% The...
