A jacketed tank is a tank with an outer jacket designed to contain heating or
cooling media. Product is heated or cooled while being mixed, blended or agitated. A
dimple jacketed tank utilizes a simple heat transfer element. First, the heating element
is created by pressing a dimpled profile into a flat sheet of stainless steel. This dimpled
sheet, referred to as an embossing, is then spot welded to the non contact side of a
stainless steel tank to create a flow passage for the heating or cooling media. The
end result is a fully welded heat transfer element that is extremely thin (approximately
½" overall thickness). The coils can remain exposed, or they can be covered with an
insulation material and then covered with a sheet of stainless steel. Jacketed tanks
are not thermally efficient and they cannot be used in a continuous operation.
