Heat to cool - Using GEA heat pumps to cool our warming planet
Explore our products
Heat accounts for more than half of the global total final energy consumption, mostly produced from fossil fuels. If the ambitious targets set in the historic Paris Agreement are to be achieved, we need to accelerate heat decarbonization and create a better world for our future generations. In the drive for a carbon-neutral future, energy-efficient heat pumps are rapidly becoming the technology of choice. Using heat pumps to cool our warming planet makes a lot of sense.

Customized GEA heat pumps
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.
GEA Blu-Red® Fusion
The GEA Blu-Red® Fusion is a combination of the successful GEA Blu chillers (low stage) and GEA Red heat pumps (high stage).
GEA open type heat pumps
Open type GEA heat pumps are designed for the direct connection to a refrigeration plant. They use condenser heat as the heat source by efficiently recovering the heat with minimum pressure loss using a compact open intercooler. They can provide heat for any industrial process and are commonly used in food and dairy plants.
GEA RedAstrum
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.
How do heat pumps work?
A GEA heat pump upgrades readily available heat source — i.e. air, water, geothermal, and waste heat—into valuable energy. Using a natural refrigerant, it efficiently reaches temperatures up to 90°C for district heating, hot water, process heating, or steam. The cycle repeats seamlessly, cutting energy costs and boosting efficiency.
In industry and commerce, the requirements for heating and process heat are highly specific. Heat pumps can very often satisfy these needs. Thanks to their efficiency and short amortization period, they represent an environmentally friendly and economically attractive alternative to conventional heating systems. A heat pump raises heat from its surroundings – water, or waste process heat – from a lower temperature level to a higher.
Whatever application may interest your company for a heat pump, it will – when its overall life cycle is considered – amortize quickly by a reduction in energy consumption and emissions that affect the global climate. In addition, emphasis is placed on using natural refrigerants such as ammonia wherever possible.

GEA Heat pumps - Products and applications
4 reasons to choose heat pump technology
1. It lowers your energy consumption
Heat pump solutions, either combined with energy-efficient refrigeration systems, or stand alone can improve your heating performance significantly.
2. It decreases your operating costs
By replacing the fossil fuel based-heating system with a highly efficient heat pump, you will lower your operating costs.
3. It reduces your carbon footprint
By reducing or eliminating the use of fossil fuel, a heat pump can help you pave the way towards your zero-emission target.
4. It meets your sustainability goals
A heat pump solution is a future-proof investment, especially in the face of ever-stricter guidelines on carbon emissions and environmental compatibility.
