Antifreeze Problem Of Closed Cooling Tower

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 of the closed cooling tower has two parts: the spray water system and the internal circulating water system (softened water).
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°C and stopped when it is above 8°C. 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.
The antifreeze of the internal circulating water system can be added with ethylene glycol solution or electric heating equipment. The formula of ethylene glycol solution can be consulted with our company.
For larger cooling system occasions, you can consider digging a pool to spray water into it, which can save the electricity consumption of electric heating operation. You can also put medicines in the pool to improve the water quality of the spray water.
3. Antifreeze problem in occasions that operate all year round
If the closed cooling tower that operates all year round is equipped with an electric control system, the number of cooling towers may change due to the load change of the main system, so the problem of antifreeze also needs to be considered.
With the continuous development of science and technology, closed cooling towers will inevitably usher in greater development and application space.
