Counterflow Closed-circuit Cooling Tower

The counterflow closed-circuit cooling tower is a high-efficiency heat exchange equipment widely applied in the industrial refrigeration sector. Characterized by a dual-core design integrating closed-loop circulation and counterflow heat transfer, it is extensively utilized in industries with stringent requirements for cooling water quality and efficiency, including chemical engineering, metallurgy, and power generation.

The core components of this equipment comprise a coil heat exchanger, a spray system, a fan, and fill media. The internal circulating process water flows in a closed loop within the coils, maintaining complete isolation from the external environment. Meanwhile, the external circulating spray water is distributed downward, and the fan drives air to flow upward, creating a gas-liquid countercurrent configuration. This counterflow arrangement significantly extends the gas-liquid contact duration, enhances heat transfer efficiency across the coil walls, and achieves a 10%-15% improvement in overall heat exchange performance compared to crossflow closed-circuit cooling towers.

Its standout advantage resides in superior water quality preservation. The closed-loop circulation prevents internal circulating water from contamination and evaporative loss, mitigates the risks of equipment scaling and corrosion, and prolongs the service life of associated units. Additionally, the equipment is characterized by low operational noise and a compact footprint. It is capable of adapting to harsh operating conditions such as high temperatures and high dust concentrations, boasting both energy efficiency and operational stability. As such, it serves as a preferred solution for modern industrial cooling systems.

This product features a high-efficiency cooling closed cooling tower, designed to be energy-saving and efficient. A 304 stainless steel metal customized option is available to provide 500 water pump units, making it an excellent choice for businesses seeking eco-friendly and cost-effective solutions.

Durability and Robust Construction

The cooling tower is constructed with premium materials, such as 304 stainless steel condenser/liner and cooling tower shell. This ensures that the product is not only aesthetically appealing but also highly durable and capable of withstanding wear and tear for more than a decade.

Customization and Versatility

This product is highly flexible and can be customized with a PLC control cabinet, catering to specific customer needs and preferences.

Efficient & Reliable Performance

The cooling tower utilizes a brand motor for the pump and fan, combined with a horizontal and 304 stainless steel impeller for the spray pump.

Applications

Industrial Process Cooling

Closed circuit towers are used to cool a variety of process fluids in manufacturing, chemical, and petrochemical plants where contamination is a concern.

HVAC Systems

They provide efficient climate control for buildings and are ideal for cooling multiple heat pumps or water-source HVAC systems, especially in sensitive environments like healthcare facilities.

Data Centers

Maintaining thermal stability in server systems requires a clean and reliable cooling method, making closed-circuit towers a preferred choice.

Pharmaceutical & Chemical Manufacturing

High standards of hygiene and purity make closed circuit towers essential for avoiding contamination of the process fluid.

Working Process

Hot water enters the cooling tower
High-temperature circulating water (such as from industrial equipment, air conditioning condenser) is pumped to the water distribution system (spraying device) at the top of the cooling tower.

Uniform distribution of water
Through nozzles or fill layers (fill), water is dispersed into fine droplets or forms a water film to increase the contact area with the air.

Heat Exchange Between Air And Water
Natural ventilation cooling tower: Relies on the towering chimney effect (hot air rises, cold air enters from the bottom).
Mechanical ventilation cooling tower: Uses fans to force air extraction or blowing to enhance air flow.
Evaporative cooling: Part of the water evaporates and absorbs heat (1kg of water evaporates and takes away about 2260 kJ of heat).
Sensible heat exchange: When the air temperature is lower than the water temperature, direct convection heat exchange occurs.

Cooling Water Collection
The cooled water falls into the water collection tank and is then pumped back to the industrial equipment or air conditioning system for recycling.
