Industrial add-on heat pumps with reciprocating compressors
GEA open type heat pumps are optimized for recovering heat from ammonia refrigeration plants. The hot gas from the refrigeration plant is cooled in an open gas cooler vessel, minimizing the superheat and pressure drop and so establishing perfect conditions for the efficient booster heat pump operation.
The heat pump series is equipped with GEA Grasso 5 HP (50 bar), GEA Grasso V HP (39 bar) or GEA Grasso V XHP (63 bar) reciprocating compressors in either a single or duplex arrangement. It can be selected in different configurations with desuperheater and/or subcooler for optimized efficiency and reduced energy costs depending on the temperature difference of the heat carrier circuit. Adding a desuperheater allows supply temperatures up to +95°C / +203°F with V XHP compressor, +82°C / +180°F with 5 HP compressor and +70°C / 158°F with the V HP compressor technology.
GEA open type heat pumps are commonly added to ammonia refrigeration plants condensing between +20 and +40°C / +68 and +104°F. The heat pump series is supplied with a highly efficient oil separator which minimizes the oil carry-over to less than 5 parts per Million (ppm) and helps eliminate the mixing of oil between the refrigeration plant and the heat pump.

Customized heat pumps are designed for optimized efficiency and a wide range of temperatures and capacities. They serve all common industrial applications and district heating. They are applied when special conditions or requirements outstrip the limits of our standard heat pumps.
A proven performer becomes even better:
Higher temperatures, an enhanced capacity range, best-in-class efficiencies, increased sustainability at lower total costs – the new GEA RedGenium heat pump has it all.
GEA RedAstrum is the standard ammonia screw compressor heat pump that meets the increasing demand for efficient heating. The series is known for its wide capacity and temperature range. It features high-end components and a sophisticated, compact design.
The GEA Blu-Red Fusion is a combination of the successful GEA Blu chillers (low stage) and GEA Red heat pumps (high stage).
CE certified.

What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
The 2022 CO2 shortage forced breweries to review their dependency on global supply chains. Many were forced to close, unable to carbonate their products. At its breweries in Germany, OeTTINGER GETRÄNKE is turning its own CO2 into a powerful lever for independence and sustainability – with the help of CO2 recovery technology from GEA.
