Marine Water Box Dimensions with Victaulic or Flanged Connections
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.
