Polytube Graphite Shell and Tube Heat exchanger

ace-gaphite-shell-and-tubes-heat-exchanger-mersen

Polytube graphite shell and tube heat exchangers are suitable for heating, cooling, condensing, evaporating or absorbing large flow rates of ultra-corrosive chemicals.

This type of graphite heat exchanger is particularly versatile

All conceivable applications are possible.

Graphilor® 3 graphite tubes are extruded, sintered and thoroughly impregnated with phenolic resin. Graphite tube sheets are manufactured from graphite block material. The tubes are cemented into the graphite tube sheets to produce the tube bundle which is inserted into the shell. The heat transfer takes place by heat conduction through the graphite tube walls between the process side and the service side.
