FRP Cooling Tower

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.

MTE 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.

These cooling towers are supplied with multiblade cast aluminium adjustable pitch fan with M.S. fabricated H.D.G. hub and S.S. hardware. Motor provided with the system is special low R.P.M. totally enclosed vertical, Flange type with enlarge & threaded shaft & sealed top is supplied with the cooling tower. The motor is totally weather proof in IP-55 construction suitable for heated & humid atmosphere. Main structural components & other light sections machined with selected preservative timber.

All structural joints are bolted with galvanized bolts and S.S./Brass Nails. Stainless Steel or Phosphor Bronze hardwares can be supplied on request at extra cost. For uniform distribution of water, hot water basin is equipped with distribution box through which the water is equally distributed in the hot water basin & is further splashed downward through spray target nozzles.

The standard cladding of profile corrugated asbestos cement sheet, the joints of which are lapped to shed water only inside the cooling tower. Specially designed eliminator from single pass pattern to 4 pass pattern of various materials are provided according to applications to minimise bleed of losses. Fill bars are designed to offer maximum splash surface and wetted surface resulting in a high heat transfer rate. The wooden fills are supported on wooden stringers or inside S.S. Wiremesh grids which assure positive & permanent positioning. Different type of fill materials with differentt shapes are available according to suited design of applications.

In the above model Fan is directly coupled with the slow RPM motors (vertical Flange mounted with sealed top & enlarged threaded shaft). However , as a option gear driven fan system can be provided if required in some stringent applications.
