FHCD Closed-Circuit Cooling Tower (Dual Air Inlet, Compound Flow)

The dual-inlet, mixed-flow closed-circuit cooling tower is based on the single-inlet design but incorporates an additional set of coolers and heat exchange packing. Both sets of coolers and heat exchange packing share a single fan system. This design allows the cooling tower to achieve maximum cooling performance with the smallest footprint, while also reducing energy consumption.

The dual-inlet crossflow cooling tower offers the highest cooling capacity per single module, making it an ideal choice for large-scale projects;

The dual-circuit coil design allows for the cooling of different media within the same tower.

SPECIFICATIONS

1--Water baffle

Effectively intercepts water droplets carried in the air, achieving a water drift rate of less than 0.001%. The detachable design facilitates maintenance of the cooler coils.  Made of polyvinyl chloride (PVC), it is corrosion-resistant, aging-resistant, and prevents microbial growth. It is installed above the cooler's water guide plate for easy cleaning.

2--Fan System

It adopts high-efficiency axial flow fans, fully enclosed air-cooled fan motors, corrosion-resistant cast steel multi-groove pulleys, and the fan casing, support frame, and protective net are made of hot-dip galvanized material. The entire fan system exhibits excellent corrosion resistance in high-temperature and high-humidity environments.

3--Water distribution system:

Made of corrosion-resistant rigid polyvinyl chloride (U-PVC), the special structural design allows for inspection and maintenance from outside the equipment without shutting it down. It utilizes large-diameter, 360-degree reinforced snap-on ABS nozzles, significantly reducing the possibility of clogging.

4--Coiled Tubing

The continuously bent, serpentine coil structure reduces the number of welding points, minimizing the possibility of leaks. The inclined design of the coil facilitates the smooth drainage of fluid from inside the tubes. The entire cooler, after welding, can withstand a pressure test of up to 2.5 MPa.

5--Cold Water Basin

The spray pump suction inlet is equipped with a stainless steel filter screen and anti-vortex plate. The cold water basin is designed with a reasonable height, ensuring that the spray pump operates without cavitation while minimizing the water volume.

6--Casing

Made of high-quality magnesium-plated aluminum-zinc steel plate, the coating contains a combination of multiple elements including zinc, aluminum, magnesium, and silicon, providing excellent corrosion resistance. It has a normal service life of over 25 years, and the corrosion resistance of the flat surfaces is 6-8 times that of ordinary aluminum-zinc steel plates. It also possesses unique self-healing properties for the cut edges.
