The Compact Marine Load Bank provides the advantage of compact size and low temperature operation making them ideal for indoor installation well within the interior of a ship. Unlike air-cooled load banks which must exhaust a very high volume of hot air to the outdoors and, as a result, are limited when installed indoors, a water-cooled load bank only needs two pipes (water in and water out) and produces no significant heat radiation to the interior space. In many cases, this will allow installation nearer to the power source or in otherwise unused space. Manufactured with a stainless steel shell and using cupro-nickel tubing joined with manifolds, water-cooled marine load banks are suitable for use with fresh or salt water.
