The main characteristics of crossflow closed cooling tower

1. The shell is made of the imported weather-resistant gel coating which resists corrosion and contains uvioresistant stabilizer and characterized by color uniformity, color fading resistance, anti-aging and surface as smooth as mirror. The strip surface is free from the reflection of light so as to prevent light pollution.

2. The connecting pipes are simple, the quantity of works is low and the installation, maintenance and cleaning are convenient.

3. The patented cooler is made of international standard T2 deacidified copper tube and welded with silver based solder.

4. The patented PVC efficient dehydrater of Ark can make the drift rate of water less than 0.0001% so that the equipment can be installed in the place with water mist; meanwhile, it is characterized by low noise, energy saving and environmental protection.

5. The circulating water tank is made of #304 stainless steel sheet and set with thee level gauge and inlet level alarm.

6. The spacious maintenance walkway, handrail and movable maintenance platform are set in the tower. The staircase is set outside the tower and reaches the platform of tower top to facilitate maintenance and overhaul. The protective net for fan drum is distributed intensively, the access door is large and the workbench is designed in reasonable size to ensure that the serviceman conducts overhaul in safety and convenience.

7. Water and electricity saving (The spray pump is characterized by low lift and high flow, and its motor is with low power and installed on the unit ) and low operating cost.

8. The streamline airfoil fan is made of aluminum alloy and characterized by light weight, high strength, high air volume, low speed in operation, low energy consumption, low noise and long service life. The adjustment can be conducted in multiple angles according to the operation load so as to utilize rated power in maximum and reach the best operating status.

9. Different from the opened cooling tower, the closed cooling tower can cool the circulating water indirectly to improve the safety of the whole cooling system.

10. The crossflow closed cooling tower is set with the pressure gauge at water inlet. The pressure gauge is also set at the water inlet of cooling equipment (Field installation) to ensure that the equipment is in safe flow range.

11. The crossflow closed cooling tower is set with water temperature display and alarm function at the water outlet, the startup and shutdown of spray system can be controlled by the digital temperature controller to adjust the temperature of inflow and outflow and conduct safe and efficient cooling for the equipment so as to save the energy.

12. The temperature control system of the electric box for closed cooling tower adopts two-stage temperature control, (1) when the temperature is lower than the temperature of primary input, the spray pump will be stopped automatically; (2) when the temperature is lower than the temperature of secondary input, multiple fans can be shut down in the same time to maximize energy saving.

III. Product structure

The working fluid (Purified water or other liquids) is circulated in the coil of the closed cooling tower. After the heat of fluid is absorbed by the coil wall, the heat of coil wall will be discharged from the cooling tower by the top fan. The spray system will be started when the fluid gets very hot (Above set temperature). The spray pump will spray the water on the hot coil wall to form water film and much heat will be removed by evaporation (Latent heat of evaporation).

Structure details:

1. Working principle

Air cooling:
The working fluid (Purified water or other liquids) is circulated in the coil of closed cooling tower. After the fluid heat is absorbed by the coil wall, the heat of coil wall will be discharged from the cooling tower by the top fan.

Water cooling:
The spray system will be started when the fluid gets very hot (Above set temperature). The spray pump will spray the water on the hot coil wall to form water film and much heat will be removed by evaporation (Latent heat of evaporation). Some spray water becomes vapor and is taken away by the air, while the water drop not evaporated will fall into the water collecting tank for circulating use. The fluid in the coil is in closed circulation, the energy consumption is low and the spray water is ordinary running water. The drift rate of spray water is less than 0.001%.

2. Copper tube

A) The patented Ark cooler for the closed cooling tower is made of international standard T2 copper tube, all tubes are exposed copper tubes without fins to guarantee cooling effect; the copper tube and the elbow are connected and welded with the silver solder, the welding spot is in high quality and the delivery test pressure is more than or equivalent to 1MPa.
B1.5mm,
B) The wall of galvanized straight tube cooler is around 1.5mm thick and this cooler is characterized by corrosion resistance, good cooling effect, high temperature resistance, regular dismounting and cleaning.

3. Cooling fin (Famous Taiwan enterpriseFormosa Plastic Group)

Packing for crossflow cooling tower
The hard PVC cloth in use is processed by hot press molding or vacuum molding and can resist corrosion and biological erosion; the square tower is designed in the whole suspension, easily installed and cleaned. The unique 3D folded hole design is featured with extremely high water collection efficiency and extremely low air resistance and can control drift loss below 0.0005% of circulating water so as to save water energy in maximum and prevent the transmission of legionnaires disease bacteria.

4. Bulk water system

Bulk water system

 

The square tower is set with unique overflow device and shower nozzle to make the cooling water stably and evenly distributed and meet the requirements of energy saving of the system under different loads (The cooking water flow will vary); the pool type shower nozzle is used for water distribution, the water tank for distribution is provided with the cover plate and the water flow sound is minimized.

5. Motor for pneumatic system

Motor for pneumatic systemMotor for pneumatic system

The motor only for the fully closed air cooling tower is of IP55 and insulation level of Level F, and suitable for 380V/3/50Hz power supply.
