Rotary Kiln Seals at IGS Industries

IGS Industries offers several powerful options in our Rotary Kiln Seal Series: An aramid, fiber-based fabric seal, a metal leaf type seal (with or without wear pads), and a metal/fabric hybrid seal.

IGS Industries’ FabriSeal is made of a Kevlar and preoxy-silicates blend, which means it’s a durable solution for sealing thermal and non-thermal equipment such as rotary coolers and dryers.

The IGS FlexMET Kiln Seal is 100% metal, which enables it to be used effectively in high temperature applications, such as rotary kilns and calciners.  100% hard compressed graphite wear pads insure the sealing surface is not scored by a metal leaf, and are self-lubricating to provide long service life.

IGS also offers a hybrid based seal* which incorporates the best of both worlds, the longevity of a metallic based seal with the efficiency of a fabric based seal.
