We have been created by integrating the companies Kulde­teknisk, FrioNordica, Kjøle­service Helgeland and Multi Kulde (Bodø).



Tromsø company Kulde­teknisk was founded in 2003 on the basis of refri­ge­ration solutions it had developed for the grocery, fishing, food processing and construction industries. The company has grown substantially, and has attracted much attention for devel­oping freezing technology which is 25 per cent more efficient than traditional solutions.

The company’s legal name is today PTG Kulde­teknisk AS

It develops and manufactures refri­ge­rated seawater (RSW) plants and heat pumps for the aquaculture and fishing industries in Norway, Europe and South America. Until its integration in PTG, its head office was at Malme­fjorden near Molde, with a branch in Grimstad and a subsi­diary in Chile.

The Norwegian company’s legal name is today PTG Frionordica AS.

Kjøle­service Helgeland was estab­lished in 2004 and offers products, service and mainte­nance, and design for refrigeration/freezing, water­borne heating, heat pumps and air conditioning.
