MADE OF ALTRA®, ALSITRA® AND CALSITRA®
Modules are made of parallel Altra®, Alsitra® or Calsitra® mat strips and compressed to the required module thickness. The compression of the modules compensates for possible shrinkage.
Straightforward mounting systems facilitate the installation of modular linings. Modules are installed either using comb anchors onto which the modules are individually plugged, or by bonding with KeRATHin® adhesive directly onto brick linings or on expanded metals. The selection of the anchor or adhesive is also crucial for the service life of the lining. Altra® modules are laterally compressed with plates or sheets to ensure the dimensional stability of the module until installation. Alsitra® and Calsitra® modules are cord modules that are sewn for easier assembly. The compression elements are removed once the assembly is completed. The modules expand, producing a closed, fire-resistant lining in the system.
THE ADVANTAGES OF HTW MODULES:
‒ easy installation
‒ high laying performance
‒ no special tools needed
‒ welded or bolted anchors possible
‒ control of the anchor fixation prior to covering it
‒ control of the compression of the modules
‒ compensation for unevenness on the furnace housing easily possible
‒ east replacement of damaged modules
