WEKA Boxcoolers® are constructed using uncoated 90/10 copper-nickel tubing. This alloy does not require a protective coating or ICAF (Impressed Current Anti-Fouling) system due to its inherent corrosion resistance to seawater and natural anti-fouling capabilities. To protect the uncoated boxcoolers against potential stray current corrosion, a WEKA Guard™ and WEKA Protector™ Type T system is applied. This exclusive design is successfully utilized in hundreds of vessels in fresh and saltwater applications worldwide.
WEKA Protector Type T and WEKA Guard
Exclusive to WEKA Boxcoolers are the WEKA Protector™ Type T and WEKA Guard™. This equipment helps to minimize potential damage to the units and hull from stray electrical currents and galvanic corrosion. The WEKA Protector Type T also allows the copper-nickel to maintain its anti-fouling capabilities, protecting the tubes from marine growth.
Our boxcoolers are constructed to be completely isolated from the hull during installation and in operation. Isolation from the ship’s hull combined with the WEKA Protector™ Type T allows the copper-nickel to maintain its anti-fouling capability.
Single or Multiple Heat Sources
A boxcooler can be designed to support single or multiple heat sources on one unit.
One Circuit—Single Heat Source
Multiple Circuits—More Than One Heat Source
A WEKA Boxcooler can be engineered to accommodate tight spaces by stepping the unit.
Bottom Mounted Boxcooler
WEKA Boxcoolers have been successfully applied in bottom mount applications, such as repower projects or when additional equipment requires cooling. In most cases, a boxcooler is installed in a top down fashion by lowering the unit into the mounting frame and welding the unit to the top of the sea chest. In a bottom mount application, a special top sea chest plate is pre-manufactured and secured to the unit’s mounting frame. The entire assembly is lifted from the bottom of the vessel through a hole cut in the hull and sea chest. The boxcooler is then fitted into the top of the sea chest and welded into place.
