Recovering heat

Standardized, ready-to-install solution for supermarkets to heat buildings or water using waste heat

June 2018

The Heat Recovery Unit provides the link between a cooling unit and the heating installation. Developed and designed for recovery of waste heat from refrigeration installations, where CO2 is used.

In Europe, around 2% of the total energy consumption for electricity is used for refrigeration in supermarkets, and within five years, 50% or European supermarkets will use CO2 as a refrigerant. If supermarkets in Europe were to use the waste heat from the CO2 refrigeration units to heat the spaces and water in their own building – generally not the best insulated places – it could lead to energy savings of EUR 1.8 billion annually.
