GEA RedGenium (North America)
One of the most efficient solution for heating temperatures up to 203 °F / 95 °C. ASME/UL/CSA certified.
Looking for our CE-certified RedGenium heat pump?
The GEA RedGenium is a compact heat pump for small to medium heat loads. At its heart are now three different reciprocating compressor series completing a total range of 7 models.
The brand-new GEA Grasso V XHP reciprocating compressor series features four super-efficient sizes. They provide twice the capacity than the existing types and a maximum supply temperature of 203°F / 95°C making the GEA RedGenium the only standard reciprocating heat pump to reach this temperature level. Thanks to the large temperature and pressure lift that V XHP technology allows, the series is fit for combined refrigeration and heating applications as well as for heating only using low-temperature heat sources, from cold environments for example.
The existing, efficient GEA Grasso V HP reciprocating compressor line remains available in three different sizes – the perfect, cost-effective match for medium capacity applications up to 158°F / 70°C supply temperature.
Aligned to the successful GEA BluGenium (North America) chiller design and equipped with heat exchangers configured and optimized according to each project’s requirements, the GEA RedGenium utilizes low ammonia charges and occupies a small footprint while delivering optimal efficiency.
Thanks to the enhanced supply temperature and capacity range, GEA RedGenium heat pumps are used in industrial applications where process heat is needed or fed into a local or district heating network.
Every GEA RedGenium can use any liquid heat source up to 122°F / 50°C (V XHP models up to 140°F / 60°C inlet), 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 +14°F / -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.
Highlights and Technical Features
- Energy-efficient solution carries the GEA Add Better Label. The GEA RedGenium V HP and V XHP standard reciprocating heat pump slashes electric consumption by an average of 25% compared to its previous solution. This translates to annual savings in energy and CO₂ emissions depending on the electric mix by the same percentage.
- Future-proof with the natural refrigerant ammonia (R717)
- Heating capacity range approx. 1,700 to 10,200 MBH / 500 to 3,000 kW*)
- Heat carrier supply temperatures up to 203°F / 95°C
- Heat source temperature range between +14°F / -10°C (minimum outlet liquid heat source or sec. refrigerant medium) and up to 122°F / 50°C (maximum supply temperature, V XHP models up to 140°F / 60°C)
- Combined cooling and heating possible
- Ammonia cascade evaporator option for efficient “add-on” set-up to existing refrigeration systems
- Fully welded shell & plate heat exchanger
- Various plate materials available, all common liquids supported
- Efficiency-optimized configuration with minimized energy costs and CO₂ emissions
- Minimum footprint, comes in one piece
- Unit ready for connection, easy installation, minimum maintenance
- Stepless capacity control via frequency inverter (variable speed range 500 – 1500 rpm) and cylinder switch-off
- Industry-leading control technology with GEA Omni control panel
