Why Fibrothal heating systems
Fibrothal combines the heating element and a high-performance insulation hot face in one pre-shaped module. Compared with a conventional ceramic fibre module lining:
- 1Low shrinkageUnder 1%, against more than 2.4% for conventional ceramic fibre modules.
- 2No recrystallisationCeramic fibre modules can recrystallise within months, turning hard and brittle and shedding fibre. Fibrothal doesn't.
- 3No saggingWith low shrinkage and no recrystallisation, the lining keeps its shape and properties for years.
- 4About half the anchorsIts own strength needs roughly 50% fewer anchors, and the supports stay out of the heat instead of conducting it away.
- 5Handles high air velocityAbrasion-resistant enough for high air velocity without a stainless inner casing, which would otherwise soak up heat every time the furnace starts.
- 6Energy saving10–12% expected with a Fibrothal hot face and ceramic fibre blanket back-up, compared with an all-module lining.
- 7Less downtimeLonger life and stable properties mean fewer breakdowns.
- 8Faster installationPre-shaped blocks go in quicker than laying modules and fixing elements on top, so the furnace is back in service sooner.
