What are the precautions for cooling tower shutdown in winter

  Precautions for cooling towers during winter operation:vgOCooling tower noise reduction treatment manufacturer

  1) Discharge circulating water and spreading water.

  2) In the case of a closed type, open the circulating water drain, exhaust port, and drain valve of the diffuser water pump.vgOCooling tower noise reduction treatment manufacturer

  Notes for winter operation:vgOCooling tower noise reduction treatment manufacturer

  When running in winter, the current of the motor will increase, please be careful.vgOCooling tower noise reduction treatment manufacturer

  In order to prevent freezing of the lower sink, please use an antifreeze electric heater.vgOCooling tower noise reduction treatment manufacturer

  Disperse water pumps, use heaters for piping, and do a good job of keeping the water level in the lower tank warm.vgOCooling tower noise reduction treatment manufacturer

  In order to prevent the freezing of the copper pipe (radiator) of the closed cooling tower and the scattered water, please pay attention to the following points:vgOCooling tower noise reduction treatment manufacturer

  In order to prevent the circulating water from freezing, please add antifreeze to the circulating water or add an auxiliary antifreeze electric heater to the piping.vgOCooling tower noise reduction treatment manufacturer

  After adding antifreeze, the freezing temperature drops and it is not easy to freeze. The higher the concentration of antifreeze liquid, the lower the freezing temperature, but the thermal conductivity will decrease. Therefore, pay attention to cooling tower selection. In addition, if there is water leakage, the antifreeze liquid will be diluted when refilling water, and the freezing temperature will rise, please be careful.vgOCooling tower noise reduction treatment manufacturer

  When the circulating water pump is running, the antifreeze electric heater heats up, so the water will not freeze. If there is an occasion where the circulating water pump is stopped, an auxiliary circulating water pump is required. Here we recommend the use of a complete set of antifreeze (including auxiliary circulating water pump, antifreeze electric heater, and piping).vgOCooling tower noise reduction treatment manufacturer

  The circulating water system is equipped with a three-way valve. When the circulating water passes through the bypass pipe to control the capacity, if the flow rate of the bypass pipe is increased, the flow velocity in the copper pipe will be reduced, and it may freeze even under load. Please set the minimum circulating water volume of the cooling tower.vgOCooling tower noise reduction treatment manufacturer

  In order to prevent the water pump and water piping from freezing, please use an antifreeze electric heater to keep the temperature of the lower water tank.vgOCooling tower noise reduction treatment manufacturer

  Other matters needing attention:

  1) The operation and maintenance manual must be read before operation, operation, and operation, and the prohibited items and operation essentials must be observed.vgOCooling tower noise reduction treatment manufacturer

  2) Never enter the cooling tower during operation. Do not climb to the upper part of the tower.vgOCooling tower noise reduction treatment manufacturer

  3) Never touch the blower when the blower may be running.vgOCooling tower noise reduction treatment manufacturer

  4) The antifreeze electric heater will heat up, please do not touch it with your hands.vgOCooling tower noise reduction treatment manufacturer

  5) Please do not drink the water from the cooling tower. If it gets into your eyes, please rinse immediately. After homework, rinse your mouth and wash your hands.vgOCooling tower noise reduction treatment manufacturer

  6) Warning labels and caution labels are affixed to each part of the tower body. Please observe the contents of the labels.vgOCooling tower noise reduction treatment manufacturer
