NSH Counter Flow Cooling Tower

NSH Counter Flow Cooling Tower

NSH series counter flow induced draft cooling tower is designed with square type structure, the volume of prevailing air is minimized. Each part of the cooling tower is designed precisely and further permits easy installation and endurance. Capacity is available from 100 RT to 1000 RT.

Features

♦ High efficiency, save energy to the largest extent
♦ Fit with various environment changes in different indutries
♦ Matched equipment running normaly
♦ Completely comply with national standards
              


Components Instruction

Casing and Water Basin

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.


Fan & Driving System

All cooling tower fans with adjustable pitch blades are applied to being balanced, it operates stably and quietly. Material chosen are A.B.S, aluminum alloy for normal standard, F.R.P or stainless steel material available for option.Small capacity cooling tower adopts direct drive low noise fan. Bigger capacity fan equipped with Belt drive speed reducer or Gear box.    


Water Distribution

Using high coefficient rotating sprinkler head made of plastic or aluminum alloy could reduce the pressure of friction loss, and the water can be distributed evenly to achieve the max thermal cooling performance.
 

Fill Packing

Used high quality & improved performance PVC with good material, it is high cooling efficiency and anti-corrosive & UL V-0. The surface of infill is corrugated to increase the filling pitch to make sure that infill is clog-free and overcome the problem of water quality. Special material for option if high entering water temperature.
 

Frame

The framework is made of hot dip galvanized steel (HDGS), to makes the cooling tower in rust-free, durable and long service life.
 

Optional Accessories

♦ Noise reduction upgrade                       ♦ Anti-Freeze heater
♦ Vibration isolator & rubber mat             ♦ Stainless steel framework / bolts and nuts (304 / 316)
♦ High-temperature upgrade                   ♦ Dual-speed Motor & VFD motorAnti-Freeze heater
