Coated Aluminium/Brass

Bundled to perfection

Coated Aluminium/Brass

The aluminum brass box coolers are used throughout the marine market and is mainly used for its strength. Nonetheless this alloy needs a protective phenol heat-cured coating and protection system due to its inherent corrosion resistance to seawater and lack of natural anti-fouling capabilities. Due to the coating the box  cooler is protected against galvanic corrosion and combines this with high heat-conductivity properties. A coated alu/bra box cooler needs an anti-fouling system to protect it against marine growth.

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.

Engineered to cool

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.

Strong and solid cooling solution

Applications

WEKA Marine’s box coolers stand as the optimal choice for small and medium-sized vessels, encompassing a broad spectrum of vessels, including tugboats, barges, fishing boats, carriers, dredgers, supply vessels, ferries, icebreakers, cargo freighters, tankers, and reefers. Box coolers provide versatile temperature control solutions, serving various functions from cooling main engines, auxiliary engines, and bow thrusters to regulating air conditioning and hydraulic systems.

Our range of box coolers offers flexibility in terms of size, shape, and configuration to suit specific cooling capacity requirements. A prominent application for our box coolers involves efficiently dissipating waste heat generated by diesel engines and other heat sources like charge air coolers, lube oil coolers, and gear oil coolers.

WEKA Marine prides itself on the innovative technology that underpins our high-performance box coolers. Years of dedicated innovation and engineering excellence have led to the development of these top-tier solutions. This commitment drives our continuous efforts to enhance and optimize the mechanical design and thermal performance of our products, ensuring they meet the exacting demands of our valued customers, the evolving market, and classification societies across the globe.

Box Cooler Protection

Ultrasonic anti-fouling system

Anti-fouling system for Coated Box Coolers

Our ultrasonic anti-fouling system is designed to keep our Coated Aluminium/Brass clear of algae, barnacles, and mussels to maintain their optimum cooling performance for the vessels critical onboard systems. There are no expensive anodes to replace, no drilling of the box cooler lid, and no specialist installation required compared to impressed current systems. All parts of the ultrasonic system are fitted on the dry side of the box cooler and its sea chest compartment. This avoids the need for any additional surveys and costs for classification documents. Our ultrasonic systems are an environmentally friendly solution, and no toxins or metallic compounds are released into the seawater.
