Bundled to perfection
Boxcoolers are efficient cooling systems designed for installation in most inland and sea-going marine applications. Boxcoolers cooling the primary circuit using seawater. A closed-circuit cooling system, which do not need any water-filters, valves, inboard heat exchanger, raw water pumps, seawater piping and strainers. The boxcoolers can be mounted longitudinal or transversal in the sea chest.
Engineered to cool
Openings in the bottom and upper side of the sea chest help to direct and focus the natural convection flow of seawater through the sea chest and across the boxcooler tubes. Additional cooling efficiency can be realized through forced circulation induced by the motion of the vessel.
Compared to an open circuit cooling system (inboard heat exchanger), a closed-circuit cooling system provides several distinct advantages. A closed-circuit cooling system eliminates the need for an inboard heat exchanger, raw water pumps, strainers, seawater piping, and the high maintenance associated with open circuit cooling systems. It also eliminates silt and sand build-up in the cooling circuit and protects the system from saltwater corrosion.
From an environmentally friendly perspective, our WME Program (including our Weka Cu/Ni 90/10 Boxcooler and circular economy service) provides a zero-discharge solution eliminating the possibility of contaminants entering the seawater.

The Selection of possible materials
The Weka Boxcooler is a completely assembled unit and is factory tested to ensure dependability. Depending on your application and situation the Weka sales and engineering team will assist you in selecting your material for your situation.
The copper-nickel Weka Boxcooler is crafted using 90/10 copper-nickel tubing. This alloy was selected based on its durability, heat exchange abilities, resistance to saltwater corrosion, and natural antifouling capabilities.
The aluminium brass boxcoolers are used throughout the marine market and is mainly used for its strength. Nonetheless this alloy needs a protective coating and protection system due to its inherent corrosion resistance to seawater and natural anti-fouling capabilities.
In some situations, a treatment of boxcoolers with phenol heat-cured coatings is necessary. This is important for the protection against galvanic corrosion and combines this with high heat-conductivity properties.
Copper-Nickel 90/10 Advantages
Amazing results after a 6 week feasibility study
This image illustrates a comparison between traditional aluminum brass tubes with hard baked coating (left side) and uncoated 90/10 copper-nickel tubes (right side). It’s the result of a six weeks feasibility test. The high copper content of the tubing provides natural anti-fouling capabilities, offering protection against marine growth. Copper alloys possess an inherent natural resistance to biofouling. Clearly, the 90/10 Cu-Ni alloy is resisting fouling from algae mussels and other marine growth. For clarification, the biofouling resistance of copper alloys is due to the copper in the protective oxide film; it is not from the leaching of copper ions.
