GC-flange EX


GC-flange EX

Explosion protected heating flanges

Explosion protected flange heaters are used to heat fluids in areas exposed to explosion hazards. The flange heater consists of tubular heating rods type GC-tube EX, flange plate, cooling section and explosion protected Ex-e terminal box. The GC-tube EX is based on our tubular heating rod (Ø 16 mm), which has proven its reliability for decades and has been enhanced for our GC-flange EX. The pressure requirements are fulfilled according to PED 2014/68/EU, those for explosive atmospheres according to ATEX 2014/34/EU.

GC-heat quality demand

All manufacturing steps of GC-tube EX and GC-flange EX are performed at our facility in Waldbröl (GERMANY) in order to meet our high quality demands. The in-house production of GC-tube EX allows the use of different materials for the tubular heating rods. Thus GC-flange EX may be used in various media.
