  • Closed cooling towers for the power industry

    Project Location: Ordos City, Inner Mongolia

    Application equipment: Generator: A generator is a device that converts other forms of energy into electrical energy. During the energy conversion process, a large amount of heat is generated due to reasons such as winding resistance and core loss. Closed cooling towers remove this heat through circulating cooling water, preventing equipment from damaging insulation materials, reducing efficiency or even causing malfunctions due to overheating, and ensuring that generators can operate stably within the normal temperature range.

  • Closed cooling towers for the new energy industry

    Project Location: Lanzhou City, Gansu Province

    Application equipment: Solar power generation: Closed cooling towers lower the temperature of the solar panels by circulating cooling liquids such as water or ethylene glycol solution, enhancing power generation efficiency and extending the lifespan of the components. Combined with waste heat recovery technology, the thermal energy can be utilized for other industrial purposes, achieving energy conservation and consumption reduction.

  • Closed cooling towers for the new energy industry

    Project Location: Chongqing City, Chongqing Province

    Application equipment: Electric vehicles and energy storage systems: During charging and discharging, the power batteries of electric vehicles generate a large amount of heat. The closed cooling tower rapidly dissipates heat through the liquid cooling system, preventing battery thermal runaway and enhancing safety and endurance. In addition, new energy storage systems such as lithium battery storage stations also rely on closed cooling towers to maintain an appropriate operating temperature.

  • Explosion-proof closed cooling towers for the chemical industry

    Project Location: Jiyuan City, Henan Province

    Application equipment: Reactor: In chemical production, various chemical reactions often take place inside the reactor. Many of these reactions release a large amount of heat and require timely cooling to control the reaction temperature. Meanwhile, the materials inside the reaction vessel often have flammable and explosive properties. For instance, in the polymerization reactions of petrochemicals, monomers such as ethylene and propylene, as well as some organic solvents, may cause explosions when exposed to open flames or high temperatures. The explosion-proof closed cooling tower can effectively cool while avoiding the explosion risk caused by electric sparks and other factors generated during equipment operation.

  • Closed cooling towers for the rubber industry

    Project Location: Xuancheng City, Anhui Province

    Application equipment: Tire manufacturing: Closed cooling towers enhance the wear resistance and service life of products through precise temperature control, preventing the physical properties of rubber products from deteriorating due to excessively high temperatures.

  • Closed cooling towers for the electroplating industry

    Project Location: Zhongshan City, Guangdong Province

    Application equipment: Electroplating tank: During the electroplating process, the temperature of the solution inside the electroplating tank will rise due to the electroplating reaction and the passage of current. Excessively high temperatures can affect the quality of the electroplating layer, such as causing problems like coarse crystallization and poor adhesion. The closed cooling tower controls the solution temperature in the electroplating tank within the optimal range through a circulating cooling system, ensuring the stable quality of the electroplating layer and enhancing the corrosion resistance and aesthetic appeal of the product.
