Commercial Cooling Tower

The main functions of Commercial cooling towers are as follows

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.

Core technology

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.
