1. Antifreeze measures for occasions that are basically not used in winter
If the closed cooling tower does not need to be operated in winter, the spray water and internal circulating water must be drained when it is shut down. The cooling tower adopts a three-dimensional inclined structure in the design of the heat exchanger to ensure smooth water flow and clean emptying. There is an air valve structure on the top of the heat exchanger, and compressed air can be introduced to assist in emptying when necessary.
2. Antifreeze problems in occasions that operate during certain periods of time

The antifreeze problem of the spray water system usually adds an electric heater in the water accumulation tray, which is generally turned on when the spray water is lower than 5 degree and stopped when it is above 8 degree . The temperature probe transmits the signal to the control cabinet to automatically control the start and stop of the electric heater. The power selection of the electric heater is determined by the circulating water volume and the outside temperature.
