With a wealth of experience spanning decades, Weka Marine specializes in providing rugged heat exchangers capable of withstanding the harsh conditions of the open seas.
Engineered to cool
Keel Coolers
A keel cooler is a closed circuit cooling system mounted externally on the vessel’s hull below the waterline. The concept of keel cooling is similar to the application of a radiator on a car. Engine coolant is circulated through the keel cooler, which transfers heat from the coolant before it returns to the engine. The keel cooler is in constant contact with seawater allowing the cooling system to efficiently transfer heat between the coolant and seawater.
Efficient cooling systems
Steel Coolers
Steel coolers are efficient cooling systems designed for installation in several maritime, stationary and industrial applications. Steel coolers cooling the primary circuit using open water. A closed-circuit cooling system, which do not need any water-filters, valves, inboard heat exchanger, raw water pumps, seawater piping and strainers. The Steel coolers can be mounted externally as well as internally into the ship’s hull.
Omega Laser Plate
Laser Plate Heat Exchangers
The Omega Laser Plate is designed to maintain the temperature of fluids (oil, water, asphalts, etc.) in the cargo holds of a vessel and to also heat up fluids prior to reaching a port for ease of pumping-out. The Omega Laser plate consists of two (stainless) steel sheets that are laser welded together by welding a custom circle weld pattern. The outside perimeter of the laser plate is fully laser welded to create a pressure boundary. The laser welding process is a fully autogenous welding process where the Omega laser welding machines melts the materials together, no filler materials are being used this process.
