The KP‑25 Seawater cooler delivers up to 2150 liters per hour of seawater chilled from 10 °C down to 0 °C. A minimum salinity of 2.6 % NaCl is required; if higher salinity is needed, a brine system can be utilized. At a seawater temperature of 15 °C, water usage can reach up to 2500 liters per hour, with a 100‑micron filtration requirement.
Seawater Coolers from Kæling Víkurafl are the result of decades of development and real‑world use under demanding conditions in Icelandic waters and around the world. Our Seawater Coolers are built to the highest quality standards and designed for those who want to leverage modern cooling technology to maximize catch value.
The KP-25 Seawater Cooler has a capacity of up to 2150 liters per hour of chilled seawater at 0 °C. Minimum required salinity is 2.6% NaCl. If sufficient salinity is not available, brine systems can be used.
Seawater usage at 15 °C is up to 2500 liters per hour, and the required seawater filtration is 100 microns.

In the design and production of seawater coolers from Kæling Víkurafl, high-quality components and materials are selected based on availability and suitability at the time of manufacture.
A key distinguishing feature is the use of titanium plate heat exchangers, which significantly enhance both performance and durability.
With regular maintenance and system upgrades, an expected service life of up to 25 years — or longer — can be achieved.
Seawater coolers are commonly used on board fishing vessels, and in certain cases also for onshore processing facilities.
Seawater coolers are available in a wide range of standard configurations, as well as custom-designed solutions for all sizes of fishing vessels and onshore fish processing plants.
Chilled seawater is highly effective in maintaining the correct temperature of the catch at all stages, from the time it is hauled on board until storage cooling begins. Seawater Coolers enable the supply of chilled seawater at different controlled temperatures for each processing stage.
This ensures optimal cooling throughout the entire process and helps maximize catch quality. Proper cooling slows bacterial growth and reduces enzyme activity, both of which are critical for preserving freshness.
The surface temperature of the sea is often higher than the temperature at the depth from which the catch is harvested. Pumping sea water directly from the surface can therefore accelerate the loss of freshness.
In addition, sea water temperatures vary significantly by season, which directly affects the cooling capacity of Seawater Coolers. An advanced control unit with electronic sensors and valves ensures precise regulation of seawater flow, delivering the correct temperature for each specific process.
Seawater Coolers can be used to pre-chill the catch to −1 °C before it is transferred to the hold after gutting and washing. The hold is then typically maintained at 0 °C.
By cooling the catch immediately in tubs using chilled seawater, the amount of ice required is significantly reduced.
The colder the sea water, the higher the performance of Seawater Coolers equipped with the Max Flow functionality. The system uses software control to actively maintain a stable outlet temperature from the cooler, regardless of variations in incoming water flow.
As a result, flow capacity differs significantly depending on whether the seawater temperature is 5 °C or 20 °C. This seawater cooler is available with the Max Flow configuration.
Since seawater temperature can vary significantly between seasons, it is important to automatically control both flow and temperature in response to changing conditions. This is handled by a modern control system that ensures precise cooling regardless of seawater temperature.
The control panel can be installed in almost any location, and multiple displays can be added if needed.
Conventional seawater coolers are connected to the vessel’s electrical system, but Kæling Víkurafl also offers hydraulically driven models for vessels that are not equipped with a generator. Hydraulic technology is particularly useful in situations where access to 230V or 400V power is limited. The compressor on the cooler is powered by the ship’s hydraulic system, the seawater pump requires 24V electricity, and the control panels require 230V.
Seawater coolers are often used alongside slurry ice machines to improve energy efficiency and overall system performance.
Typically, the seawater is chilled to 0 °C before being pumped into the slurry ice machine. This enables higher ice production rates, faster processing, and significantly lower energy consumption compared to using unchilled seawater directly.
There are many factors to consider when selecting a seawater cooler, and it is essential to conduct a focused needs analysis. This includes, for example, the volume of catch that needs to be cooled over a given period and the seawater temperatures during the fishing season. Different fishing grounds and seasonal variations can have a significant impact on these requirements.
Don’t hesitate to get in touch with us. We take pride in providing outstanding service and only offer high-quality products we trust — products that we know contribute to increased catch value.
We offer a wide range of Seawater Coolers suitable for fishing vessels of all sizes.
