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.
Polytube features
Heat Transfer area up to 1850 m2
Tube Sheet Diameter up to 2100 mm
Design Pressure: up to 7 barg on process side and up to 11 barg on service
Design Temperature up to 220°C
1:1 Substitution: same Footprint as Heat Exchangers from other Original Equipment Manufacturers
