Stay cool, Sail cool
Box Coolers
These parts are manufactured by VULKAN COUPLINGS, Germany pioneers in marine drive technology.
Furtermore, VULKAN components are used in powerplant facilities or in industrial applications as well.
VULKAN production program includes following types, most available from the manufacturing site in Germany but some common ones are also available from our warehouse in Moschato:
Coated Aluminium - Brass
Ultrasonic System
When biological fouling is an issue, the ultrasonic system can protect the box coolers against marine growth. Bio-fouling reduces its cooling efficiency, especially for low-temperature circuits on a non-moving vessel, or regions with rich marine creatures.
Technology
The versatility of the WEKA box cooler is equally matched by its cooling prowess. Its straightforward design can be adapted into various configurations and shapes to precisely fit available space and cooling demands.
A typical box cooler features a U-shaped tube bundle, firmly secured with a tube sheet and a waterbox to guide the flow of water. This bundle is fastened with a gasket to a mounting frame, anchoring the cooler to the vessel’s hull. This construction technique enables the removal of the waterbox while keeping the bundle fixed to the hull, preventing seawater from entering the vessel when the cooler is in use.
To cater to a broad spectrum of cooling requirements and diverse structural limitations, WEKA box coolers are available in multiple configurations, encompassing both round and rectangular designs.
Applications
WEKA Marine’s box coolers are the premier choice for small to medium-sized vessels, including a wide range of ships like tugboats, barges, fishing boats, carriers, dredgers, ferries, icebreakers, and tankers. These coolers provide versatile temperature control, supporting functions such as cooling main and auxiliary engines, bow thrusters, air conditioning, and hydraulic systems. Their design offers flexibility in size, shape, and configuration to meet specific cooling needs. A key application is the efficient dissipation of waste heat from diesel engines and other sources like charge air, lube oil, and gear oil coolers.
WEKA Marine is dedicated to innovation, with years of engineering excellence driving the development of these high-performance solutions. This ongoing commitment ensures that WEKA’s box coolers continue to meet the stringent demands of customers, market trends, and international classification standards.

Anti-fouling system for Coated Box Coolers/Box Cooler Protection
The ultrasonic anti-fouling system of WEKA Marine, ensures that Coated Aluminum/Brass remains free of algae, barnacles, and mussels, maintaining optimal cooling performance for critical onboard systems. Unlike impressed current systems, it requires no expensive anodes, no drilling of the box cooler lid, and no specialist installation. All components are installed on the dry side of the box cooler and sea chest compartment, eliminating the need for additional surveys or classification costs. This environmentally friendly solution releases no toxins or metallic compounds into the seawater.
