Product Description

NRT series counter flow induced draft cooling tower is designed with bottle type structure, So that the volume of prevailing air is minimized. Every part of the cooling tower is designed and made precisely and further permits easy installation and endurance due to light weight and strong structure. The testing report of cooling capacity proves its high efficiency.

Features:

Casing and Water Basin

Adopting small ventilation resistance packing and special designed FRP/aluminum alloy high efficiency fan, greatly reduced the motor power. Smaller motor power are designed for low noise model, save more power, double speed motor for optional to power saving according to customers' special requirements.Fiberglass reinforced polyester(FRP) is applied with water-resistance resin and high quality fiberglass mat. With good moisture, high gel,high strength, spray the gel-coat on FRP parts by machine and is thermal formed. The surface is as smooth as mirror and could resist ultraviolet radiation. Also, it is colorfast and durable.
 

Axial Fan
All cooling tower fans with adjustable pitch blades are applied to being balanced, so that it can operate stably and quietly. Material chosen are A.B.S, aluminum alloy, stainless steel and F.R.P. 
 

Fan Drive
Small capacity cooling tower adopts direct drive low noise fan. Bigger capacity fan equipped with Belt drive speed reducer. Adjust belt tension through automatic spring to save the manual maintenance. Total enclosed structure can assure the low noise operation. This series of cooling tower have passed the GB7190.1-1997 quality certification of supper low noise. Further more the belt is durable without negative effect from water vapor and sunshine.

 

Water Distribution 
The using of high coefficient rotating sprinkler heads made of reinforced plastic or aluminum alloy can reduce the pressure of friction loss. Besides, the water can be distributed evenly to achieve the max thermal performance. 

Infill
Standard and low noise cooling tower are using high class thermal formed PVC sheet. The sheets are added with industrial plaits material and long fiberglass to slow the aging and increase the strength. High temperature cooling tower is using P.P. Infill that could withstand up to 90 degreeC water temperature. The surface of such infill is corrugated to increase the filling pitch to make sure that infill is clog-free and overcome the problem of water quality.


Steel Parts
All the steel parts and hard wares are made of hot dip galvanized steel(HDGS), so that the cooling tower is rust-free, durable and long service life. And the frame is stable and with good rigidity, the load is evenly distributed among each foundation, which makes operation and assembly easily.
