About us

Manufacturing in Norway and a compre­hensive service network allow us to look after customer require­ments for quality and delivery precision.



We help to cut energy consumption and increase profi­ta­bility for our customers in the marine, industrial, commercial and air conditioning markets.

We develop and deliver environment-friendly solutions for refri­ge­ration, freezing and enhancing energy efficiency. We are a substantial supplier to the grocery sector in northern Norway and to the seafood market natio­nally and internationally. 


Chilled and frozen with top taste and nutrient content 

We know that the end-product value increases when fish are chilled and frozen while at their freshest and when their nutrient content is at its best. Our solutions also improve operating economics by cutting fuel consumption and working time. In partnership with our customers, we identify the perfect tempe­rature and solutions which are cost-efficient and environment-friendly.

Our marine customers:
White fish vessels, pelagic vessels, well boats and suppliers of factories and processing plants.

The value of perfect temperature

We are dedicated and attract highly competent colleagues. 


We are predictable and profi­table, and deliver quality at every level. 


We are a complete supplier of sustai­nable tempe­rature and energy solutions.

We have taken the PTG name from the initials of our holding company, Perfect Tempe­rature Group, and adopted the group’s slogan – the value of perfect temperature.

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.


FrioNordica was estab­lished in 1983 and ranks as Norway’s leading supplier of refri­ge­ration technology for maritime appli­ca­tions. 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

Kjøle­service Helgeland was estab­lished in 2004 and offers products, service and mainte­nance, and design for refrigeration/freezing, water­borne heating, heat pumps and air conditioning. It covers the whole Helgeland region of northern Norway, with its head office in Mosjøen and branches in Mo i Rana, Sandnes­sjøen and Brønnøysund.

Multi Kulde

Multi Kulde in Bodø was estab­lished in 1998 and has long experience and broad expertise in design, project management and execution, assembly and construction of complex refri­ge­ration facilities. Multi Kulde AS has a 40 per cent interest in Ålesund-based Multi Kulde Vest, which is in turn the sole owner of Multi Kulde Nordvest in Molde. The company’s legal name is today PTG Multi­kulde AS. 

In December 2021, Norway’s biggest expert on cooling technology PTG became part of the Nordic Climate Group. Estab­lished in the spring of 2021, Nordic Climate Group is a holding company consisting of a network of Swedish and Norwegian refri­ge­ration enterprises.
