In October 2010 the specialists of our company carried out the works on insulation of a cyclone filter dust collector. The Technical Department had decided to use the combined method of isolation. Liquid insulation "TSM Ceramic" and basalt mats had been used for a thermal insulation of cyclone filter dust collectors. Insulation material "Folar B" (two-sided foil) and aluminum sheets.had been used as a protective material. The corresponding review is the proof of a qualitative work performed and the benefits of the material.
