GEA has launched new versions of its Red series of heat pumps with all models available with an ammonia cascade evaporator making them compatible with any refrigeration system, and the RedAstrum series now has a total of seven models.
The new GEA Red heat pump cascade version allows clients to add the heat pump onto any existing refrigeration system while using one single ammonia cascade heat exchanger that works as the condenser for the chiller stage and as the evaporator for the heat pump stage.
The chiller can condense at lower temperatures while the heat pump evaporates at higher temperatures resulting in increased efficiency of up to 10% and eliminating the need for two separate heat exchangers and the hydraulic cycle.
The GEA RedAstrum series previously included four Grasso M series screw compressor models. Now there are three further sizes which include two smaller Grasso M models and the larger Grasso LT model.
The swept volume range of available screw compressors, and so the capacity range of the RedAstrum series, has increased by 80% (depending on operating conditions).
