Box Cooler

Efficient and space saving cooling

A Box Cooler is a vessel water cooling system. It comprises a U-tube bundle that is fitted in the sea chest on the side of a vessel, saving space in the engine room. The sea chest is equipped with inlet and outlet grids. Cooling sea water enters through the inlet grid and flows along the U-tube bundle to the outlet grid, thus cooling the water inside the tubes. The cooling effect is achieved by the forced circulation of sea water when the vessel is moving or by natural convection when it is stationary.

Description

Box coolers can be used for a wide variety of temperature-reducing duties on a vessel, from cooling the main engines, auxiliary engines and bow thrusters to air conditioning and hydraulic systems. Kelvion Box Coolers are ideal for small and medium sized vessels, including for example: tugboats, barges, fishing boats, carriers, dredgers, supply vessels, ferries, ice breakers, cargo freighters, tankers and reefers.

Versatile technology to suit your needs

The cooling power of the Kelvion Box Cooler is matched by its versatility. Its simple design can be configured in different versions and shapes to suit the available space and cooling requirements. To cover a wide range of cooling duties and constructive boundary conditions, Kelvion Box Coolers are available in many variations in round and rectangular design. The round shape is mainly for purposes with smaller cooling capacities. This type covers cooling surfaces between 2 - 21 m². The maximum possible diameter of the bundles is about 400 mm.

The rectangular form is used for larger cooling capacities and covers cooling surfaces between 9 to 120 m². The width of the box cooler bundle goes up to about 400 mm, while the maximum length is about 2000 mm. As the space available for the box cooler is often limited in the sea chest, the bundle must follow the contours of the hull as closely as possible to generate the largest possible cooling surface. This is achieved by executing the box cooler with a stepped bundle in several sections, each with a different depth. Independent of the design Kelvion Box Coolers are available with bundle depths between 400 and 1800 mm. Even bigger types are available on request.
