Closed reverse flow cooling tower
Closed reverse flow cooling tower is a kind of reverse flow closed circulating water system. This circulating system is an automatic spray control system, which can save power and water to a great extent. Due to its compact structure and small size, it can be placed in the workshop, so it can be used for medium frequency power supply cooling, mechanical water jacket cooling, etc; The heat exchange area in unit space is large, so it is more suitable for low temperature (35-30 ℃) cooling projects with small temperature difference, such as water source heat pump units, air compressors, etc.
Cooling capacity:25-250 T/h(Single room)
Application area:Casting, forging, air compressor, central air conditioning, ground source heat pump, water source heat pump unit, mechanical water jacket, die casting machine, injection molding machine
Cooling medium:Pure water, quenching fluid, hydraulic oil
  • Advantage
  • Principle
The closed reverse flow cooling tower of Wuxi Wosin adopts advanced industrial design, which is not only efficient and energy-saving, but also environment-friendly in industrial application. The closed reverse flow cooling tower of Wuxi Wosin  is  careful material selection and exquisite design makes the equipment have better quality in operation and maintenance.

1. Selection of materials.
The shell of the equipment is made of imported (POSCO, Korea / Nippon Steel, Japan) magnesium aluminum zinc plating plate, which has the function of self-healing of incision scratch; The spray pump adopts Taiwan Chuanyuan type cooling tower special pump, the whole line is not overloaded, when the pump runs at any working point of its performance curve, the consumption power of the pump does not exceed the rated power; The fan adopts domestic famous brand, which can effectively control the noise.

2. The design is reasonable.
Our designers have been engaged in the design of cooling tower industry for many years, and have rich experience in the design of similar products. Combined with the characteristics of domestic transportation and packing, the cooling capacity of the designed tower fully meets the requirements, and the tower structure is compact.

3. Complete specifications, non-standard customization.
Closed reverse flow cooling tower models from wxlt-n-6 to wxlt-n-200, complete specifications, according to the demand of non-standard custom explosion-proof cooling tower


The working fluid (pure water or other liquid) circulates in the coil of the closed cooling tower. The heat of the working fluid is dissipated into the water flowing through the coil through the coil. At the same time, the air outside the unit enters from the air inlet grille on the side of the bottom of the coil, which is opposite to the flow direction of the water and flows through the coil in reverse direction. A small part of the water evaporates and absorbs the heat, The hot and wet air is discharged into the atmosphere by the exhaust fan at the top of the cooling tower; The rest of the water falls into the bottom tank, which is recycled by the pump to the water distribution system and back to the coil.
