Low GWP Heat Pumps

Air-to-water and water-to-water heat pumps have been designed to make a greater range of commercial buildings, from commercial offices to schools to hospitals, more sustainable. These heat pumps feature energy-efficient technology, such as electronic vapor injection (EVI) compressors, while using refrigerants with low global warming potential (GWP). When delivering heating and cooling simultaneously, such heat pumps can be five times more efficient than a boiler-chiller combination. Depending on the size of the building, multiple chiller types can be combined to meet the required load and performance.

Our award-winning team offers professional advice and support to help you achieve your energy reduction objectives, supporting you in reducing energy use, cutting running costs and carbon emissions.

When it comes to replacing equipment, we can provide unbiased advice on how to select the most efficient and reliable plant, that will go on saving you money and carbon emissions over its life-time. The Cooltherm team can provide advice and guidance on which refrigerant to use and also importantly on the HFC refrigerant phase-down.

R290, a natural refrigerant with a GWP of just 3, has gained significant attention due to its energy efficiency and low environmental impact. It is a suitable alternative to hydrofluorocarbon (HFC) refrigerants, which are currently being phased down globally due to their high global warming potential.

Our team can talk you through the application of R290 in commercial chillers, especially heat pumps, a product in high demand with the demise of the gas boiler for heating.
