Fiberglass Cooling Tower
Special Design, Special Quality
Fiberglass cross-flow cooling towers are optimized in design of their structure and process on the basis of the traditional square GRP cooling tower. The function of each inner part is reasonably selected. All components and materials are strictly selected and tested to ensure a long service life and reliable operation. The unique excellent mechanized process improvement provides reliable guarantee for high quality of the cooling tower and effectively reduces the weight of the tower to make the BHD series of square counter-flow GRP cooling towers with the characteristics of small volume, light weight, high efficiency, durability and stable operation. At the same time, the cooling towers can be equipped with a new frequency conversion device to realize automatic regulation of fan speed with cooling water temperature under different temperature conditions and different load conditions, so as to achieve the purpose of energy saving and noise reduction, and save equipment operation cost for users.

Cooling: The cooling tower achieves heat dissipation by spraying high-temperature water or other liquids onto the packing layer, utilizing the heat exchange between water and air, thereby reducing the liquid's temperature to the set range.
Realize recycling: The cooling tower conveys the dissipated water back to the equipment for recycling, thereby reducing water consumption and improving the utilization efficiency of water resources.
Protecting equipment: In industrial production, some equipment needs to operate in high-temperature environments. However, high temperatures can have adverse effects on the equipment. Therefore, cooling towers are required to reduce the temperature of the equipment to the normal range to ensure its normal operation.
Energy conservation: Cooling towers can reduce the temperature of liquids to the set range by utilizing natural wind or forced convection through fans, thereby reducing energy consumption and improving energy utilization efficiency.
Major components
Electric motor
The motor is the special motor for totally closed cooling towers and it is suitable for continuous operation in a hot-humid environment for a long term with high efficiency, low noise, long service life and high reliability. And also, the domestic or imported motors and corresponding inverters can be equipped according to customer requirements.
Fan
The surface of fan is treated with the electrochemical anticorrosion. The fan passes the balance debugging, has the space warp structure with large chord angle, and has the characteristics of large air volume, high efficiency, static operation and corrosion resistance.
Filling
The padding is the combination of high quality modified PVC trapezoid blocks with self-reinforcing air inlet surface and water collecting surface, good surface hydrophilicity, large heat dissipation area, small wind resistance, high cooling efficiency and corrosion resistance.
Frame
The frame adopts high strength steel parts with the surface treated by anticorrosion treatment. It has features of corrosion resistant, light weight and easy assembly
