GEA raises heat pump temperature to 95ºC
18th October 2021
GERMANY: The use of a new Grasso V XHP reciprocating compressor has enabled GEA to raise the temperature supply capability of its RedGenium low-charge ammonia heat pump to 95ºC.
The brand-new GEA Grasso V XHP reciprocating compressor series will be available in four sizes from 2022. They provide twice the capacity than the existing types and a maximum supply temperature of +95°C.
Thanks to the large temperature and pressure lift that V XHP technology allows, the series is suitable for combined refrigeration and heating applications as well as for heating only using low-temperature heat sources, from cold environments for example.
The GEA RedGenium is a compact heat pump range of 11 models for small to medium and up to slightly higher heat loads. They can use any liquid heat source up to +50°C, for example wastewater, surface water and ground water, or with a liquid secondary refrigerant for combined cooling and heating applications.
The GEA Grasso V HP and the new V XHP models even allow heat sources below zero providing secondary refrigerant outlet temperatures down to -10°C for combined refrigeration demands.
Alternatively, all GEA RedGenium heat pumps can be equipped with a cascade evaporator, directly charged with hot ammonia gas from a refrigeration plant, to efficiently recover waste heat.
