The Cooling Tower industry subjects its wooden towers to the harshest environments conceivable. The wet-dry cyclical conditions and structural designs intensify the undisciplined seasoning of the wooden members, resulting in warping, twisting and checking. Wood preservative treatment is based on two separate -- yet interdependent-- requirements: penetration and retention of the chemical preservative. max-ion Cooling Towers maintain timber quality as per IS 2372 and have in house treated timber workshop having AsCu timber treatment plant as per IS 401 wherein the preservatives (Copper, Chromium and Arsenic salts) are pressure impregnated in the timber and designed to react with the wood cell components so that the active elements, copper (Cu), chromium (Cr) and arsenic (As) are fixed into the wood's structure. The arsenic component protects the sapwood from insect attack, the copper and arsenic from fungal degrade, while the chromium component chemically locks the elements into the timber, offering high resistance to leaching. Because the treatment is resistant to leaching, it can be used on timber that will be exposed to the elements or used in-ground.
