Refrex® fabric is woven out of threads made out of different rovings. The rovings are assembled out of a specified number of endless Refrex® filaments with a fiber-diameter of 10-12 micron. No binders are added only a “sizing”, a temporarily coating which protects the Refrex® fibers during the weave process. Refrex® 1200 and 1400 filaments and textiles are non-oxidizing, non hygroscopic, chemically resistant, have a low conductivity and a good abrasion resistance.
Using this special fabric, we manufacture several custom made Refrex® products:
Refrex® heatshields to prevent overheating of tube skin surfaces of radiant coils and reformer-tubes and to reduce surface temperature on other furnace internals
Refrex® mono- and multi tube bellowsare flexible, prefabricated protrusion seals for one or more tube passings, that are installed between in- and outlets of process tubes and a furnace / reformer roof.
Refrex® zonedividers: a hanging, “flexible wall” from the roof of a furnace to split up the furnace in several areas.
