Operation principle: The closed cooling tower cools down fluid with the principle of water evaporation absorbing heat. Spray water is started at the bottom of the cooling tower and working fluid circulates in the radiator coil of the closed cooling tower. Spray water distribution system and spray nozzle with spray system pump,where some water is evaporated and heat is absorbed, so the temperature of working fluid in pipe is reduced. Water in hot air and unevaporated water is stopped by a manger and flows through PVC heat exchange layer where the water is cooled down by flowed water and falls in water pond at the bottom.Then the water is recyclingd to the water distribution system with the water pump and returns to spray on coil pipes.Circulating cooling is conducted repeated in such way. Product features: Apply combined flow type cooling way with high-efficiency dewaterer and low drift water rate. Cooling medium circulates closely with no impurities…
