Plastic auxiliary machine: / soup Advantages and disadvantages of closed cooling tower: 1. The whole pipeline system is closed circulation, and the circulating water is distilled water, which can make the vacuum furnace heat exchanger and small pipelines not scale, pollute, or corrode, and almost make the vacuum furnace Double the life. 2. There is almost no water consumption in circulating water. The same type of equipment saves about 7,000 tons of water per year.

3. The closed cooling tower is equipped with intelligent control. The same type of equipment can save 30,000 kWh per year. 4, the installation is simple, there is no need to excavate the underground water pool, the pipeline is easy to use, because it is a closed loop, the pipeline required for small tube damage is DN200, and the use of the open tower must use DN300 or two DN200 pipelines.
Disadvantages of closed towers: Closed cooling towers cost three times as much as open towers. (However, after 10 years of closed towers, the recycling value is 80,000-100,000, and the opening tower has almost no value)
Advantages of the open tower: 1. The cost of opening the tower is relatively low, which is one-third of the price of the closed tower.
Disadvantages of open tower: 1. It is necessary to excavate 1-2 20 cubic meters of groundwater pool. Due to the water drop and open head loss, the power consumption is more than that of the closed tower. Two sets of pumps are needed, which consumes a lot of electricity.
Recommendation: Use a closed cooling tower 1. Protect the life of the equipment and reduce equipment maintenance.
2, environmental protection and energy saving, the price difference between the closed tower and the open tower can be saved within three years.
3. The closed tower uses a copper tube as a heat exchanger, and the equipment has value preservation.
