Product Description

REVERSE FLOW CLOSED COOLING TOWER

Cooling medium: water, oil, or other liquids Condenser Material: Copper Tube Condenser, Stainless Steel Tube Condenser shell material: 304 stainless steel plate, Galvanized sheet, magnesium aluminum zinc plated plate. Compact structure, small footprint, and relatively high height. Adopting modular design, maintenance is convenient and fast. Meanwhile, due to the adoption of a closed-loop system, impurities and dirt in the cooling water are less likely to accumulate, reducing the maintenance cost of the equipment.

Working Principle:
A counter current closed cooling tower is a type of cooling tower where the wind direction is opposite to the direction of the spray water. The inlet form of the counter current closed cooling tower is bottom inlet, and dry low-temperature air is sucked in from the lower part of the tower, alternating with the falling spray water in the opposite direction. After absorbing heat and moisture, the hot air is discharged by the top fan.

Product Advantages:
Efficient cooling:Adopting a counterflow design, the cooling water stays in the tower for a long time, increasing the cooling area of the cooling water and thus improving the cooling efficiency.
Energy conservation :The closed loop system reduces the evaporation loss of cooling water, saves water resource waste, and reduces energy consumption.
Stable and reliable:The steel structure design is stable and reliable, able to adapt to various harsh environments, and the closed-loop system reduces the fluctuation of cooling water temperature and humidity, thereby reducing the failure rate.

Exquisite Craftsmanship:
Save:Compared with traditional open cooling towers, it achieves fully enclosed internal circulation of cooling water (purified water), without the need for excavating water tanks, and is convenient to relocate. Suitable for areas with water scarcity.
Environmental protection:Through fully enclosed circulation, the circulating cooling water is protected from pollution and can be used sustainably. Closed cooling towers protect the atmospheric environment due to the low evaporation of spray water.
Stability:Circulating water usually adopts soft water closed-loop circulation, which prevents the formation of scale at high temperatures and increases the service life of pipelines and equipment components. By setting system parameters, ensure the effectiveness and stability of the cooling process.
Energy conservation:The frequency conversion technology used enables the cooling system to adjust the air volume and spray volume according to changes in ambient temperature, control the start and stop of fans and spray systems, and achieve energy saving in the cooling process.
Service life:The closed cooling tower designed and produced by our company adopts high-quality metal structural materials to enhance the corrosion resistance of the equipment. Extended lifespan, minimal maintenance, and low cost.
