The supermarket chain Waitrose has a long tradition in using eco-friendly refrigeration.
For the sale point in Bromley, in the South of London, we developed the first HFO chiller in the world to be installed in a supermarket.
The project concerned two 180 kW air cooled chillers VHA with reciprocating compressors and HFO-1234ze refrigerant with low environmental impact.
The comparison of this plant with a sale point in Canterbury with a similar system using R290 as refrigerant has pointed out a reduction of 22% in energy consumption. It is a remarkable result for a cutting-edge project, awarded with the ACR News Awards 2012.
