The basic idea in our innovation project was to change the component that traditionally has made these kinds of systems unnecessary complex. Competing businesses used heat exchangers that historically was made for the oil- and gas industry. Proff Kulde has adapted the heat exchangers to meet the needs of the refrigeration industry, which enables a more compact design of the RSW-system and a cheaper production. The customers benefit through a better price.

The technical leader in Proff Kulde, Morten Andre Engen, explain some of the innovation: - Evaporators developed for oil- and gas industry is poorly suited for low flow (on the CO2-side) and draining of liquid and oil. Our new developed heat exchangers are adapted for this and allows us to halve the use of expensive high pressure refrigeration components.

Proff Kulde has developed a new type of evaporator for use in RSW-systems with CO2 as an eco-friendly refrigerant. An RSW-system is a chilling system that uses seawater to keep fish and other catch chilled on board fishing vessels until it gets delivered at the fish reception on land.

The authorities have enforced strict regulations for the use of gasses such as freon (R22) which was forbidden in 2015, and an increasing number of businesses choose to change into systems using CO2 as a refrigerant. Ammonia is sometimes used as a refrigerant in RSW-systems, but that´s usually in the bigger vessels. The compact and fitted design of Proff Kulde´s RSW-solution enables the use of RSW-systems for a larger part of the fishing fleet.

Review at Innovation Norway

Proff Kulde recieved a great review by Innovation Norway in the aftermath of the development project supported by the environmental technology scheme. In addition, the solution is published at the website The Explorer, which is Norway´s official marketing site for green technology.

Refrigeration technicians work on chilling-, freezing- and heat pump systems with piping, and electric and automized control systems. Therefore it´s important to possess high competence in refrigeration technology, construction, behavior, and uses of these systems. Mechanics, electronics, automatics, plumbing, and welding is a few of the areas our skilled technicians must master.

Proff Kulde regard itself as a spearhead on the automation area, and in most larger deliveries automation is included as a central part and is important to ensure energy effective operation of a chilling-/ heat pump system. Control systems used in chilling-/heat pump systems is an important part of our technological development work.

In recent years Proff Kulde has delivered new or upgraded automation solutions to many customers in the land-based fishing industry, and automation is an important part of both RSW-deliveries and other industrial chilling-/ heating systems we deliver.

Scale ice

We offer industrial scale ice machines that produces clean and fresh scale ice perfect for the food- and fishing industry. The ice is flat and thin, between 1,8 and 2,2 mm. The ice forms on the inside of a drum by pouring a film of water over it, then contact freezing it in to a thin sheet of ice and the ice is cracked off by a harvesting blade.

Granual ice

Granual ice varies in size from 10 mm to 15 mm and has no particular shape. Granual ice machines are made for commercial and industrial use and are regularly used in the fishing industry. The produced granual ice is sub-cooled to -1,5 ° C / -2 ° C. One of the advantaged of using granual ice is that it has an even chilling effect and a constant chilling temperature. It doesn´t melt easily and can be stored for a longer period, up to 30% longer than other types of ice.

We are able to install other types of ice machines on request, such as cube ice machines, slurry machines and block ice machines.

Proff Kulde offers different types of systems, from CO2 split-uniters and smaller cold- and frozen storages to big booster-systems for larger cold- and frozen applications. Both split- and booster-systems can be delivered for indoor and outdoor assembly. We also offer small compact-aggregates with R290 (propane).

Characteristics and benefits:

  • CO2 refrigerant has become a popular choice for use in cold- and frozen storage.

  • CO2 is well suited for heat recovery; the frozen storages can be delivered with heat recovery as an option.

  • CO2PRO_Systems can be projected and dimensioned to fit most needs.

Drying systems

Energy effective and eco-friendly drying systems based on CO2 and glycol for drying of for example fish products.

Climate-controlled storage

Control of temperature and humidity is essential for good quality on stored goods. A climate-controlled storage for example for stockfish will give you exact control of temperature and humidity and increase the quality and sales weight. A climate-controlled storage makes it possible to store and dry independently of the season.

CO2 as a natural refrigerant

Our main focus is on CO2 as a natural refrigerant. The reason for this focus is our very positive experiences concerning the relationship between real performance compared to theory. CO2 scores highest of all the refrigerants in this field. CO2 is also the easiest refrigerant to use for full heat recovery.

Combined solutions provide a higher COP and an increased environmental benefit

Most people have heard of the calculation of COP in heat pumps. It´s the relationship between produced KW heat and the used KW. But what if we need chilling? A heat pump or a chilling system is a technical solution that typically moves heat energy from one media with lower temperature to one with higher temperature. An example: An air-to-air heat pump retrieves heat from the air outside and adds it to the air inside. The temperature outside is relatively speaking getting colder and inside it gets warmer. If we use “the cold side” for chilling of for example a cold storage, the COP calculation expands. The expanded calculation looks like this: (KW produced heat energy + KW used in cold storage) / added KW to heat pump system => Higher COP

This is obviously eco-friendly solutions which also results in lower energy costs for you as a customer.

A CO2 chilling system is more similar to CO2 heat pumps than the systems for traditional refrigerants. Consequently, it is very easy to use the warm side of a CO2 chilling system (heat recovery). It is also easier to emit high media temperatures on the heat dissipation side. 60-80C hot water production is possible without the use of more compression steps.

All chilling systems emit huge amounts of heat which is a great advantage if you need heating. It can be used for heating of water or as part of the total heating of commercial buildings.

Proff Kulde also works with heat recovery from for example ammonia-systems.
