Marine coolers

BLOKLAND U-type coolers, box coolers, and heat exchangers

Box coolers and heat exchangers are known for their reliability, long lifespan and short delivery times. All coolers are adjusted according to each particular case and the engines used. Apart from the traditional operation on cargo ships they are, among others, also installed on passenger ships, pushing boats as well as service vessels. An especially compact design is the box cooler. The supplied radiator housing allows an easy and space-saving fitting anywhere in the engine room. Tube bundle heat exchangers for oil and water as well as the repair of marine coolers complement our range of products.

FERNSTRUM keel coolers

Known as the GRIDCOOLER® this heat exchanger is installed as a "keel cooler" on the outside of the ship's hull. The great advantage of this indirect cooling lies in the fact that no seawater has to be passed through the engine room. By this corrosion and sedimentation within the cooling pipes are avoided.

Even in ice the GRIDCOOLER® works trouble-free. The installation is very easy to do. The special design and various fitting options result in very low water resistance. The flow-enhancing cooling ducts combine low pressure loss with high stability.

Additionally, costs are saved because of the omission of a seawater pump, heat exchanger, valves and filters as well as complex tubing.

The GRIDCOOLER® is available in over 8000 different models and delivered ready-to-install with screw fittings and premium quality gaskets made of neoprene. The close collaboration between shipyards and engine manufacturers ensures a perfectly designed construction as a whole.
