Introduction

The closed cooling tower originates from the evaporative cooler, but it is actually a heat exchanger that combines the performance of the water-cooled cooler and the conventional cooling tower. It is also a heat exchange between the water cooler and the air cooler device.

It is characterized by spraying water outside the partition wall heat exchanger and forced ventilation. The heat is transferred from the cooled fluid in the partition wall heat exchanger through the wall surface to the spray water outside the wall surface, and then forced by the spray water and air. Convection is transferred to the air, and the heat transfer from spray water to air is mainly composed of the latent heat of spray water evaporation and the sensible heat exchange between spray water and air. The cooled fluid circulates in a closed manner between the partition wall heat exchanger and the external process equipment.

FEATURES

◆ Low Maintenance
Unlike most forced draft cooling towers, the GWBB cooling tower utilizes large access doors for easy entry and exit.

◆ Low noise
All cooling towers are made of aluminum alloy axial flow fan, forward-inclined vane structure design, streamlined inlet air duct, small wind resistance, and low noise.

◆ Long Life Construction

Rugged, corrosion-resistant galvanized steel is standard, and the S304 series stainless steel and Magnesium-plated aluminum-zinc plate housing is available as an optional upgrade to the partial or entire cooling tower structure.

ISO certified factories ensure high quality factory assembly.

Delivery

Application

1. Induction heating and metal melting equipment, such as: high and medium frequency quenching equipment, medium frequency power supply and electric furnace, induction diathermy furnace, insulation furnace, etc. cooling.

2. Cooling of circulating water in various reactors and condensers in the chemical industry.

3. Cooling of large motors, diesel engines, rectifier equipment, welding equipment, hydraulic stations and continuous casting equipment.

4. Cooling of metal die casting molds, injection molds and other large molds.

5. Cooling of industrial solution, such as quenching liquid, electroplating liquid, etc.

Advantages of closed cooling tower:

1. The cooling medium is completely closed to prevent debris from entering the cooling pipeline system and the evaporation loss of the cooling medium.

2. Use soft water as cooling medium, no scaling, no clogging of pipelines, and few failures.

3. The dual cooling method of air cooling and spray water evaporation heat absorption is adopted, and the cooling efficiency is high.

4. The device is small in size, takes up little space, and is easy to move and place, without the need to build a pool.

5. Using automatic intelligent control, it can automatically change the cooling mode according to the requirements of working conditions, and the operation is simple and reliable.

6. Widely used, it can directly cool the quenching fluid, oil, alcohol and other media that have no corrosive effect on the heat exchanger. The media has no loss and the composition is stable.
