The new GEA Blu-Red Fusion is said to be suited for combined cooling/refrigeration and heating demands at low heat source temperature levels and high temperature lifts between heat source and heat sink. Models are based on the existing Blu chiller and Red heat pump family, which are configured and combined according to manual selection or depending on the capacity, heat source and heat sink temperature requirements.

Heat source outlet temperatures are supplied between +15 and -15°C while the maximum supply temperatures at the hot side reach up to 70°C (reciprocating compressor-based heat pump stage with GEA RedGenium); and up to 80°C (screws compressor based heat pump stage with GEA RedAstrum).

Cooling capacities range from 300 to 1,800 kW with heating capacities of 450 to over 2,400 kW (sec. refrigerant at +12/+6°C, heat carrier at +50/+70°C).

The intermediate stage is equipped with a single ammonia-ammonia ’cascade’ heat exchanger which reduces capital investment and makes an intermediate liquid cycle redundant which reduces the differential pressure of both stages and does not waste power on glycol or water pumps. The efficiency benefit is said to easily reaches 10% and more.
