Emergency power and port power applications for seagoing vessels and inland vessels require specific quality requirements for materials and construction. This includes copper coolers and stainless steel parts. Oversluizen produces copper radiators in house that have been developed for applications at sea. In addition to radiators, we calculate and supply air and water cooled coolers for mega yacht building. All coolers and components are calculated in-house and can be carried out with Lloyds Register, DNVGL, ABS, RSMS and other approvals. Coolers for 3G or higher are also possible.
