ICA Sweden is the leading grocery chain in Sweden. Company set a high bar for its sustainability goals. It has focused on energy efficiency improvement and a gradual switch to renewable energy and refrigerants with a smaller carbon footprint. Between 2006 and 2020, greenhouse gas emissions in the group’s operations were reduced by 76%.
ICA stores chose propane-based waterloop solution
Several ICA Sweden stores underwent energy-saving renovations and were furnished with propane (R290) Green Wave line refrigerated display showcases, operating in Hydroloop system from Freor. Natural coolants glycol and propane have almost zero impact on ozone depletion and emit about 90 % fewer greenhouse gases than synthetic coolants. The installations were carried out by partner company Coolfors Sweden – a ‘green thinker’ with extensive expertise in refrigeration technologies.
Propane-based chillers and upright freezers were chosen for the meat, dairy, pre-packed product, and frozen food sections:
- Multidecks JUPITER – versatile refrigerated cabinets for meat, vegetables, dairy products, beverages, and pre-packed products.
-
Freezers ERIDA – upright freezer cabinets, ensuring perfect preservation of frozen produce and providing great visibility.
Cost-effective system
Hydroloop system is easy to install – multidecks, serve-over counters, freezers, and cold rooms can all be connected to the same system. When you connect all the cooling equipment to a single glycol liquid circuit, you get a system that requires minimal maintenance, little space (no machinery room is needed!), and is environmentally friendly. Very small refrigerant quantities are needed if compared with a non-autonomous system.
Pump station, manufactured by FREOR, ensures the circulation of glycol within the system. The residual heat is emitted through a dry cooler, usually located on the roof of the building. The waste heat from cooling units can also be used to heat your premises in cold months of the year.
