Safe and efficient catalytic and thermal oxidisers for VOC purification and solvent destruction

LESNI has extensive experience in the design and supply of air and liquid thermal oxidisers which safely and effectively destroy waste air laden with solvents from a diverse range of industries. We design and supply turnkey packages including catalytic oxidisers, regenerative oxidisers with two, three or five canister oxidisers, as well as waste to energy incinerators.

The thermal oxidisers use the principle of thermal combustion to convert airborne Volatile Organic Compounds (VOC) and genreal solvents into carbon dioxide and water vapour. The purification efficiency is designed to exceed 99+%, with very little consumption of energy, due to the high thermal efficiency and heat recovery of the system.
