Efficient cooling and freezing are essential to preserving catch quality from the moment it comes on board. With long experience in marine refrigeration, Teknotherm delivers robust RSW and freezing systems for rapid chilling, stable temperatures and reliable operation in demanding fishing vessel applications.


For fishing vessels, refrigeration is directly linked to product quality, capacity and value. Catch must be cooled or frozen quickly, handled correctly and kept at stable temperatures until landing or further processing. Our systems are designed to support efficient catch handling, high up time and consistent temperature performance at sea.
RSW systems provide rapid chilling of large catches in refrigerated seawater and are widely used for pelagic species such as mackerel, herring and horse mackerel. Cooling the catch quickly and evenly helps preserve quality and maintain product value from fishing ground to shore.
For vessels requiring frozen products, we deliver the full freezing solution — including brine systems and low-temperature cargo holds — tailored to the vessel’s catch profile, processing capacity, layout and operating requirements.
With long experience in ammonia refrigeration and natural refrigerants, Teknotherm provides robust, efficient solutions for high-performance fish cooling and freezing, delivering reliable capacity, stable operation and better conditions for preserving the value of the catch.
