KP-6 Seawater Cooler
The KP‑6 Seawater cooler delivers up to 500 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 1,000 liters per hour, with a 100‑micron filtration requirement.
The KP‑6 seawater cooler is compact yet powerful
Delivering up to 500 liters per hour.
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.
KP‑6 seawater cooler at a glance
The KP-6 Seawater Cooler has a capacity of up to 500 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 1,000 liters per hour, and the required seawater filtration is 100 microns.
Durability and reliability
Expected service life of up to 25 years
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 for maintaining the correct temperature at every stage
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 seawater is often higher than the temperature of the catch
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 chill water down to as low as -1°C
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.
Sea water temperature affects performance
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.
Option for multiple chilled seawater outlets at different temperatures
Advanced modern control systems with remote access
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.
Remote service available
Option for electrically or hydraulically driven seawater coolers
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 and slurry ice machines work well together
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.

Our cooling specialists assist with system selection
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.
