Cooling and heating under control

    Whether in a hospital, chocolate factory or radio studio, or in a residential area or research laboratory: our air-conditioning units, (reversible) chillers, and industrial heat pumps ensure the right temperature in a wide variety of locations.

    Our product range at a glance

    We offer mass-produced or customised air-conditioning units, chillers and industrial heat pumps with a power range of between 6 and 4,000 kW. Choose between a water- or air-cooled cold water unit for internal or external installation. We use natural and synthetic refrigerants, such as propane, ammonia, hydrofluroolefins (HFOs), R32, and others. We will be happy to advise you – also when it comes to special functions, such as free cooling and heat recovery.
