Closed cooling tower


1.Pre-cooled heat dissipation packing and heat exchanger coils are used for cooperative heat dissipation structure, good cooling efficiency and small size.
2. Set up air inlet louvers at the air inlet, to avoid direct sunlight into the tower, to prevent algae breeding, keep spraying water clean.
3. Heat exchanger coil adopts T2 copper tube, designed to withstand 1.6Mpa pressure to keep the fluid free from pollution.
4. The heat exchanger coil adopts modular design and is equipped with an access door, which can facilitate the maintenance of nozzle, packing, floating ball valve and other internal construction.
5. Adopt aluminum alloy axial flow fan, with natural exit air speed, avoiding hot air return
BHD series square counter-current GFRP cooling tower has small size, light weight, high efficiency, durability, stable operation and other features. At the same time, the cooling tower can be equipped with a new type of inverter device, which can automatically adjust the fan speed with the cooling water temperature under different temperature conditions and different load conditions, thus achieving the purpose of energy saving and noise reduction, and saving the operating cost of the equipment for users.
