AMTOM Limited Designs, Manufactures, Installs and Commissions Catalytic Thermal Oxidisers. Large volume waste streams with low combustible content may require the use of catalytic oxidation. Catalytic thermal oxidisers use a catalyst to accelerate the rate of oxidation reaction whilst remaining unaffected itself. The catalyst enables the destruction of organic compounds at up to 10 times the rate and at much lower temperatures than a conventional oxidiser. It is the ability of the catalytic oxidisers to achieve a high level of destruction at a significantly lower temperature that reduces the operating cost compared to a conventional oxidiser even operating with heat recovery.
