Products & Applications Overview

Thermal Process & Combustion Technology for the Aluminum Industry


A market leader in thermal process engineering solutions, Clinotherm were the first to develop and patent edge stacked ceramic fiber veneer modules called Clinoblocks. Clinoblocks are cemented to dense refractory and provide reduced heat loss and thermal shock. Clinotherm has continued to develop refractory products that combine high thermal efficiency, standard and custom shapes, that provide exceptional adaptability, reduced down time for repairs, and reduction of build time for new installations.

With ever increasing fuel prices, the increased efficiency provided by Clinotherm refractory solutions can enable significant cost savings.
