Teknotherm Marine AS

Teknotherm has a history dating back to 1926 as a designer, contractor and manufacturer of high quality refrigeration systems. Our strategy today is to be the preferred supplier of HVAC- and refrigeration systems for marine and offshore installations.

Being a partner to, among others, the international shipbuilding industry, part of our strategy is to be where the customers are. Thus we have established subsidiary companies in Gothenburg, Sweden, Wuxi, China, Szczecin, Poland, St. Petersburg, Russia and Seattle WA, USA – in addition to our Norwegian branches in Ålesund, Oslo, Bergen and Tromsø. Furthermore we have a well established network of agents and representatives in strategic markets all around the world.

We have our own in-house engineering and production. We design and build custom-made/tailor-made units, as well as our own control systems and switchboards, we do installation work and have a service- and spare parts department that will follow up your installation throughout its entire life time.

Customizing our units in response to the specific needs of our customers has made Teknotherm a flexible company, able to rapidly respond to changes in need or requirement. Furthermore, we have an organization that is alert to the latest changes and requirements within the industry, enabling us to position our company on the front line of development.

Our wide range of products covers i.a. any kind of refrigeration installation for freezing or cooling the catch at sea. A typical plant for installation onboard a fishing vessel includes one or several of the following options:

Plate-freezer systems

Teknotherm refrigeration plants for plate-freezing can be delivered in any size required, 

and supplied as vertical or horizontal models, with a variable number of freezing stations and station size. 

Air blast freezing system

Teknotherm air blast freezing plants can be supplied either for «Batch» or «IQF» freezing of the catch. 

Cargo holds

Teknotherm air-coolers for cargo holds can be supplied either for natural/gravity air-circulation, or forced air-circulation, directly or via ducted system.

RSW systems

Teknotherm RSW plants mean rapid chill down and storage of the catch close to the freezing point in Refrigerated Sea Water, by using our highly efficient RSW-chillers.

Teknotherm also supplies plants and systems for ice-making, special low-temperature plants, brine freezing plants etc., in addition to complete HVAC-systems and other refrigeration systems.
