DK heat exchangers heat recovery and water cooling systems

Beginning, with a simple idea of offering the refrigeration installers an efficient, flexible and safe system for using the waste heat from several refrigeration plants, to provide free heating. Since then, we have been supplying combinations of cylinders and heat exchangers that reliably and effectively save energy and protect the environment. DK are the industry’s specialist choice for energy efficiency in refrigeration technology.

Thanks to our flexible and handcrafted production, we offer solutions for refrigeration plants from 5 to 500 kW as well as for heating drinking and/or heating water. Continuous customer focused design solutions have added further products to our equipment range, such as the DK chiller and the DK suction gas heat exchanger.

Since 2008 we have been offering systems for waste heat recovery for transcritical CO2 refrigeration plants. More than 750 delivered systems with over 2,000 installed heat exchangers (as of March 2020) make us confident that we have found a good solution. The DK evaporator for CO2, which we have been offering for five years, is also becoming increasingly popular.

Ideal solutions for the concrete requirement with the highest flexibility in design and production. All components such as evaporators, vessels and stainless steel double tube coolers are manufactured at DK. Thus, we offer an individuality which cannot be found with suppliers of mass products.

For the safety of the compressor and to optimize the performance of the refrigeration system with a degree accurate evaluation of liquid subcooling and suction gas superheat.

Hot water at no charge - Use the waste heat from your refrigeration system for tap water warming and/or for heating
