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.
