The Original box cooler
Steel Cooler
Steel coolers are efficient cooling systems designed for installation in several maritime, stationary, and industrial applications. Steel coolers cool the primary circuit using open water. A closed-circuit cooling system does not need water filters, valves, inboard heat exchangers, raw water pumps, seawater piping, and filters. The steel coolers can be mounted externally and internally into the ship’s hull.
Engineered to cool
Technology
The steel cooler is the original box cooler, built since the early days after the second world war. Its straightforward design can be adapted into various configurations and shapes to precisely fit available space and cooling demands.
A typical Steel (box) cooler features a rectangular-shaped tube bundle firmly welded together to guide the water flow. This bundle is installed into a specially designed mounting frame.
Redundancy Arrangements
Double Circuit
When the need arises to cool two distinct water circuits or when redundancy is a requirement, it becomes feasible to furnish the steel cooler with dual compartments. This configuration allows for two separate circuits to be accommodated within a single cooler, effectively minimizing the space constraints.
For the redundancy version, these two compartments can be operated either in parallel or in series, contingent upon the installation of supplementary piping and valves. The implementation of a dual circuit and redundancy design can be seamlessly applied to our box coolers, offering versatility and adaptability to specific operational demands.
Strong and solid cooling solution

Steel Coated
In some situations, a treatment of steel coolers with phenol heat-cured coatings is necessary. This is important for the protection against galvanic corrosion and combines this with high heat-conductivity properties.
Steel Galvanised
Galvanized steel cooler is built with regular steel tubes that have been coated in zinc to make them corrosion resistant. Regular steel is made of iron which will rust when exposed to (sea)water. Over time rust will corrode a steel part to the point of failure. To prevent this from happening Weka will provide a custom-made steel galvanized cooler.
