NST Cross Flow Cooling Tower

NST Cross Flow Cooling Tower

NST series cross flow square  cooling tower is available in capacity for single cell from 100 tons to 1000 tons, various modular combinations of cooling towers are designed to meet different requirements.This cooling tower is highly used in heating, ventilation, air-conditioning, and light to medium processing applications.


                        
Features

♦ Thermal isolated  casing, Stainless steel 304 /316L material
♦ Prevents external heat into the tower and insulation, damps the vibration
♦ Resistant to acid and alkali, effectively eliminate the oxidation on the surface of the galvanized
♦ Modular design, high strength, good rigidity, nice appearance
♦ Factory assembled, easy installation and maintenance
              


Components Instruction

 

Casing and 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

Adopting low speed, big chord length and width of blade fan, with stable wind speed, low noise, and high efficiency, etc. Enough air flow can be easily get at low rotating speed of the fan, what’s more, blade angle can  be  adjusted according to different climate condition. Used aluminum alloy fan blades, solid fan or hollow type available for different customers' request.
Using motor with IP55 protection grade, F class insulation grade, smooth operation, low failure rate. Options: Siemens, ABB
 

Distribution system

Using the unique overflow device to realize smooth and even water distribution under different sustem load, the device completely eliminates the drift loss of coolig tower. Hot water basin cover avoids water pollution by foreign objects falling into hot basin. Meantime, it avoids direct sunlight and inhabit growth of algae.
 

Fill Packing

Used high quality & improved performance PVC with good material, it is high cooling efficiency and anti-corrosive & UL V-0. Brand new PVC materials, integrated eliminators and louvers. The infills are hanging type, environmental friendly and  big coefficient of heat transfer, good hydrophilicity. Small wind resistance, high ventilation performance. Special material for option if high entering water temperature.
 

Frame structure and fasteners

Leading structure design and high-quality materials to make frame structure and fasteners, the standard configuration of structure and fasteners is superior hot-dip galvanized steel, good anti-corrosion, design lifespan is more than 15 years. Stainless steel or F.R.P frame structure available for poor water soltion, and SUS304 or SUS316L for fasteners.  
 

Optional Accessories

♦ Noise reduction upgrade                      ♦ Anti-Freeze heater                             
♦ Vibration isolator & rubber mat            ♦ Handrail & Safety caged ladder
♦ High-temperature upgrade                  ♦ Dual-speed Motor & VFD motorAnti-Freeze heater
