Water Cooling Tower
Special Design, Special Quality
BHD series of square cross-flow GRP 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.
Technical parameters of BHD series of square cross-flow GRP cooling towers
1. The measuring points (R) and (T) are all in the direction of air inlet of the cooling tower. The equivalent diameter D=1.13 W L, among which, L and W are respectively the side length of the cooling tower.
2. It must be quiet around the cooling tower before determination of noise, the environmental noise should be 10dB (A) or more lower than the noise at the measuring point R under normal work of the tower, otherwise, it should be corrected. Please consult the technical personnel of the company for corrected value.
3. DF shown in the figure is the distance of equivalent diameter of the air outlet: 1.5≤DF≤5m.
