Heat pumps

 

Example:

Kraft-Foods Marabou

Kraft-Foods Marabou is a major producer of chocolate for the domestic and export markets.
Products need cooling and a refrigeration system assures correct temperatures in all rooms.
The excess heat from the refrigeration system is distributed to out-door air via cooling towers.

When a new heat pump was to be installed to reduce consumption of oil, this cooling tower circuit with its water basin was a good heat source for the heat pump.

Ref-Tech installed a heat pump that has performed very well for over 6 years.
Savings of fuel costs have been substantial and pay-back time for investment only 18 months.

IBM, Kista
