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.

Countercurrent Tower Overview

Helps minimize pump head requirements

Multiple models, cell sizes and assemblies available

Choice of wood or fiberglass composite construction

Working Guidelines

In a counterflow cooling tower, air and water flow in opposite directions. The air first enters the open area below the PVC filling medium and then rises vertically. At the top of the tower there is a pressurized nozzle from which the water jet flows through the PVC filler in the opposite direction to the air flow. In general, counterflow cooling towers have a smaller footprint than crossflow cooling towers, thus saving space. In addition, counterflow cooling towers are less likely to freeze in cold weather.

Cooling Tower Parts and Functions

The following is a list of counterflow cooling tower parts that may need to be repaired and replaced during the life of the cooling tower:

Water Supply System

Counterflow cooling towers distribute water through a gravity flow distribution or pressurized sprinkler system into the PVC fill media, over which hot water basins are installed at the top of the cooling tower. A series of nozzles in each hot water basin distributes the water evenly over the PVC fill media.

Fans

The fan is centrifugal, and the axial fan system requires only about half the motor horsepower of a centrifugal fan system of the same class, resulting in significant energy savings. The fan is made of aluminum alloy with a wide twisted blade design for high airflow and low noise operation.

Filling medium

Low wind resistance suspended PVC filling medium, high heat exchange efficiency, saving electricity.

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.
