Tower Tech designs the finest counter flow cooling tower that remains flexible to various industrial applications. In the counter flow cooling tower, the air flow and water flow directions are opposite to each other. The airflow, first of all, enters into the open area below the fill media, and then it is driven up vertically. The top of the tower contains pressurized nozzles, from where the water is sprayed and the water flows down via the fill, and opposite to the flow of the air.
As stated earlier, counter flow cooling tower design dictates that the water brought to the nozzles has to be pressurized since the air flows in the opposite direction of the water. So to let air flow in the tower without any restriction, the set of pressurized pipes and nozzles are positioned farther away for counter flow cooling tower as compared to how it is positioned in crossflow cooling towers. Counter flow cooling tower design covers less ground space.
Maintaining counter flow cooling towers requires it to be idle and not in operation. The counterflow cooling tower manufacturers put emphasis on the point of maintenance while selling the cooling towers. Moreover, counter flow cooling towers are highly suitable for hot climates, unlike crossflow cooling towers that let the moist environment pave the path for algae growth inside the cooling tower.
The counter flow cooling towers are considered an ideal choice for having more acceptable configurations for applications, where space is the limiting factor. Eventually, making the choice depends on the application and the characteristics of the intended site. At Towertech India we would be happy to help you identify if the counterflow cooling tower is the best solution for your requirements.
Advantages of the Counter Flow Cooling Tower Design
The cooling tower remains resistant to freeze due to the spray water distribution.
The heat transfer becomes efficient because of the breakup of water in spray.
Counter flow cooling towers fit the small spaces efficiently covering small ground
Since they are smaller in size they are also lighter in weight
It consists of several filling options which allows it to be used for different applications considering the quality of water.
Convenient to use in dusty and other environmental conditions.
Disadvantages of the Counter Flow Cooling Tower Design
Owing to the pump requirements, the long-term and initial costs are high.
Using variable water flow can be daunting, as the characteristics of the spray may be pessimistically affected.
Hard to use variable flow rates
Counter flow cooling tower has the tendency to freeze the water in the system within the low flow rate systems.
The fall of water droplets on the surface of cold water basin causes noise emission.
It uses up more power as compared to cross flow cooling towers.
The counter flow cooling tower can be engaged in the mechanical draft and in natural draft cooling towers. Counter flow cooling towers are contoured with an induced draught fan placed on the top and they are directly mounted to the motor. The fan prompts the average air into the tower in order to draft it upward. Consequently, the speed of exhaust air remains much higher than the air that enters which results in low-pressure drop and even lower circulation.
