Cooler for storage rooms

Features

Air coolers are finned heat exchangers in which a working fluid heats up with heat absorption from the environment to be cooled, without changing the aggregate state. The units serve as components of a system, e.g. for conditioning the room air or cooling goods.

Evaporators are finned heat exchangers serving as components of a refrigeration system, in which liquid refrigerant evaporates with heat absorption from the environment to be cooled. The units are used e.g. in deep-freeze applications in food storage.

State-of-the-art refrigeration technology in La Lorraine’s deep-freeze bakery storage room

The Belgian family-run company La Lorraine uses Güntner HIGHSTORE coolers and thermowave plate heat exchangers in its new central deep-freeze storage room in the Czech Republic. The industrial bakery which has experienced rapid growth in recent years had the foresight to create impressive infrastructure north-west of Prague which boasts storage space for double the production capacity catered for in 2012. The fully automated high-bay deep-freeze storage room has around 27,300 pallet spaces.
