300 Ton Cooling Tower

Closed Circular Cross Flow Cooling Tower(AHC)

It refers to a cooling tower in which the cooling hot water passes through the packing from top to bottom, while the air flows through the packing from horizontal and oblique directions, and the flow direction of hot water and the air is nearly 90 degrees (some manufacturers also call it direct cooling tower).

Features Of Closed Circular Cross Flow Cooling Tower

a. Crossflow cooling mode is adopted, and the bleaching rate is very low;

b. The internal space of closed circular cross flow type cooling tower is large and the maintenance is very convenient;

c. Totally closed circulation to eliminate the blockage caused by sundries;

d. The heat exchanger adopts the stacking mode of building blocks, which can be installed and disassembled layer by layer;

e. The closed type cooling tower using hot water circulation, no scale formation;

f. This wet and dry cooling tower does not need a pool, occupies a small area, and is easy to locate.

Structural Drawing Of Closed Cross Flow Cooling Tower

Application Scope Of Closed Circular Cross Flow Cooling Tower

The closed circular cross flow cooling tower fan adopts a silent large blade fan, which makes the noise at the outlet of the cooling tower lower. The gravity pool type water distribution is adopted. The spray water enters into the basin and then passes through the nozzle under the action of gravity. The heat exchange filler under the spray and the heat exchanger of the closed cooling tower. After passing through the heat exchanger, it naturally flows into the bottom sump. Therefore, the noise of a closed circular cross flow cooling tower is lower than that of a closed counter flow cooling tower. There was no sound of water dripping into the pan. Compared with the counter flow cooling tower, the closed circular cross flow cooling tower can be assembled side by side, which has a smaller floor area. Therefore, the cross-flow closed cooling tower is more suitable for occasions with high noise requirements and a small floor area.

Square Cross Flow Cooling Tower (AH)

The cross flow tower is the abbreviation of cross flow cooling tower. The cross flow tower refers to equipment that the fresh air was forced suctioned from two sides under the action of the fan and motor, while the water drops flow from top to bottom in the filler by gravity.

The flow direction of the air and water is 90° angle, mass transfer and heat transfer are carried out in the filler.

Details Of Square Cross Flow Cooling Tower

Reducer & Fan

Reducer: Transmission bearing chooses import NSK or NTN standard axle bearing, long service life and is not easy to damage, belt choose the import high strength V belt, high strength, wear resistance, long service life. Also, provide the AOSUA patent reducer with an external visualization device.

Fan: Use a high-quality aluminum alloy cross fan with an adjustable angle. Meet customer's different requirements for the process like a blast capacity. The fan must through strict balance and orientate before delivery, four-leaf forward plate-type design, to make the force of every piece is small, advantages: little vibration, low noise, high efficiency, power saving.

Petals Nozzle

The nozzle is made of ABS plastic one-time injection molding with high strength long service life. The nozzle water distribution is uniform, work pressure is low, widely suitable pressure range, and not easy to jam. Because of its locking and anti-loosening device, make the connection of it and the water distribution tightly, not shed, ensure long-term safe operation of the water distribution system. Under the condition of normal use, the service life of the nozzle is 20 years. Good heat dissipation effect, especially suit for power plant cooling water.

Fill

This cross flow type cooling tower uses the AOSUA designer's latest research and test results, anti-UV and corrosion resistance PVC vacuum forming molding,good entirety rigidity after assemble, low air resistance, remarkable thermodynamic performance.

The Casing

The square type cooling tower owns material that is FRP composite,surface gel coat use imported raw material, inside the colour has an anti-UV stabilizer, smooth surface, aging resistant.

Steel Frame

The open circuit cooling tower is made of international superior angle iron, high intensity, good durability. All the steel frames through strict hot-dip galvanizing, good preservative effect, high intensity, easy to assemble. The corrosion process accord with the British standard BS ENIS01461: 1999 standard.

Square Counter Flow Cooling Tower(AF)

The square counter flow cooling tower, as the name suggests, its overall shape is square, can be cuboid, can also be a cube. In the process of circulating water and air exchange, water flows from top to bottom under the action of nozzle and gravity, and the flow direction is certain. The wind action produced by the fan can be from bottom to top, which is opposite to the flow direction of water, which is called "counterflow"; the square counter flow cooling tower has low consumption and is often used for cooling refrigeration equipment and industrial large and medium-sized machines.

Why Choose Square Counter Flow Cooling Tower?

Under the same conditions, the filler volume of the square counter flow tower and square cross flow tower is about 20% smaller, so the cooling efficiency of the heat exchange process is higher. In addition, the square induced draft counter flow cooling tower water distribution system is not easy to block, the drenching filler is not easy to keep clean and aging, the moisture backflow is small, and the anti-freezing and deicing measures are easier.

Advantage of Square Counter Flow Cooling Tower

a. Beautiful and durable. The surface is made of imported colored gel coat, containing ultraviolet absorbers, bright and clean as a mirror, anti-aging, and difficult to fade. The color of the tower can be selected according to the user's requirements.

b. Environmental protection and low noise. The use of a low-speed fan, high water induced anechoic pad, streamline water collector, effectively control the impact of the cooling tower on the environment.

c. Low operation cost. The selection of energy-saving large diameter fan has the advantages of large air volume, small power, and low energy consumption, which can effectively save the operation cost for users; the multi-speed motor can be selected according to the requirements of users, which can adjust the air volume according to the change of ambient temperature, so as to further reduce the operation cost.
