HVAC&R | Freezing Trawler Engenes Fiskeriselskap AS

Teknotherm was awarded the contract to supply the HVAC and refrigeration for a freezing trawler for Norwegian ship owner Engenes Fiskeriselskap AS.

Engenes Fiskeriselskap’s new vessel is designed for bottom trawling as well as pelagic trawling. It will have a modern factory deck arrangement to handle and freeze both white fish and shrimps, and ensure a high quality catch. The vessel is designed by Kongsberg and can accommodate up to 29 crew members.
