Timber Cross Flow Cooling Towers Manufacturers Suppliers India

North Street offers treated timber packaged type Induced Draft Cross Flow Cooling Tower. These towers are specially designed to deliver highly reliable operation under corrosive atmospheric condition.





Induced Draft Cross Flow
Unique Timber Cross flow Towers by use of Seagull Bars either in PVC or in Steel, 'C' type Drift Eliminators, Aerodynamic FRP Fans, Drives with or without Gear Boxes, all to give highest thermal efficiency. Use of Seagull Bars ensure film & splash cooling both. This gives more capacity by 20-25% over the conventional fill design.

STRUCTURE :

Selected quality Pine Wood as per IS 2372 treated with Chromated Cooper Arsenate ( ASCU Chemicals ) as per IS 401.

WATER DISTRIBUTION :
Open gravity type basin made of tongue and grooved treated timber Plank / marine plywood fitted with polypropylene spiral target nozzles to have uniform hot water distribution over the entire fill area.

TIMBER :
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.


North street 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.

Advantages of treated timber :


• Durability: Long life under hazardous conditions.
• Versatility: Can be used in direct contact with fresh or salt water.
• Flexibility: For designing economically to overcome difficult site environment.
• Effectiveness: It is cost efficient
