Marine Water Boxes (WSC)
Marine water boxes are an available option on all evaporator and condenser sizes. Epoxy coating of the water boxes and
clad tube sheets are available for extreme duty applications. Caution: There is some nomenclature confusion in the
industry. McQuay refers to our standard dished heads as “dished heads”. Some manufacturers refer to them, or similar
devices as “water boxes”. They are not “
marine water boxes” with removable end covers as illustrated below.
