Cooling Tower Water Treatment
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.
The spray water tray is made by one-time molding process, with no seams as a whole, eliminating dripping and splashing water at the water tray. The frame is formed by one-time bending of hot-dip galvanized steel plates, with C-shaped groove reinforcement design. The fiberglass reinforced plastic air duct is formed by vacuum introduction process, and its strength and toughness are increased by more than 50% compared with the hand lay-up process. All fiberglass reinforced plastic parts have abandoned the original hand lay-up process. The panels are made by pultrusion, the water tanks by molding, and the corners by molding. The overall appearance of the equipment is more aesthetically pleasing. The semi-enclosed water chamber is set up to effectively block debris and prevent direct sunlight from shining on the water chamber, which could cause pollution to the water system by algae, bacteria, etc. The tower body is equipped with fiberglass reinforced plastic (FRP) protective plates, and the outer layer of the protective plates is formed with high-quality imported gel coat, which is resistant to ultraviolet rays and aging, thus extending the service life of the equipment. It adopts a modular design of 100-700 square meters per hour, suitable for connecting multiple towers together. It occupies a small area and is elegant and stylish. Steel parts are welded into blocks before leaving the factory, reducing on-site welding and ensuring the safe operation of the equipment.
