What Is FRP cooling tower

FRP cooling tower meaning is fiberglass reinforced plastic cooling tower innovated in a special way for heat exchange allowing air and water to come into contact with each other to the lower temperature of hot water. FRP cooling tower working is mechanically considered as heat rejection device where wase heat will be rejected to the atmosphere through the aid of a cooling water stream towards a lower temperature.

FRP cooling tower is commonly applied in oil refineries, chemical plants, petrochemical plants, thermal power stations and for cooling buildings through HVAC systems. This cooling towers could be either in natural draft or induced draft.

Cooling Tower Come in Different Types

Counterflow cooling towers, crossflow cooling towers, natural draft cooling towers, forced draft & induced draft cooling towers and industrial cooling tower.

We offer two types of FRP cooling tower, you can learn frp cooling tower specification more.

What are FRP Cooling Towers Used for?

Basically, FRP cooling towers are designed for rejecting and disposing heat from chillers. It is less efficient for air cooled chillers than water cooled chillers because of the rejection of heat from water in the twer to near wet-bulb temperatures

FRP Square Type

Our cooling towers are alternative for Round shape cooling tower also economical and Proven Reliability have been installed in many applications. Spray nozzles provides uniform water distribution.

The low speed, high efficiency fan and low pressure drop and design to optimize the energy consumption. Fill shall be high efficiency film Honey comb type, rigid, corrugated PVC sheets with integral louver and drift eliminator that are conducive to cooling tower and UV protected.

Fills shall be resistance to rot, decay and biological attack with maximum -flame-spread rating of 5 according to ASTM E84.

Drift eliminators shall be efficient enough to effectively limit drift loss to 0.005% of the designed -flow rate.Cooling Tower components are made of anti-corrosive material suitable for cooling water application. Starting range from 60RT – 1000 RT single Cell

How Cooling Tower Works?

Hot water is coming at the inlet of the tower and pumped up to the header. The header contains nozzles and sprinklers which is used to spray water, and it will increase the surface area of water. After that, water comes to PVC filling; it used to reduce the speed of water. At the top the cooling tower, fans are used to lift air from bottom to the top.
Because of slow speed and more contact area of water, it makes a good connection between air and hot water. The process will reduce the temperature of water by evaporation process and cooled water is collected at the bottom of the cooling tower, and this cooled water is used again in the boiler.

Different Parts of Cooling Tower

  1. Eliminator: It is not allowed to pass water. Eliminator is placed the at top of tower, from which only hot air can pass.
  2. Spray Nozzles and Header: These parts are used to increase the rate of evaporation by increasing surface area of water.
  3. PVC Falling: It reduces the falling speed of hot water and it is similar to beehive.
  4. Mesh: When the fan is ON, it uses atmosphere air which contains some unwanted dust particles. Mesh is used to stop these particles and do not allow to enter dust in to cooling tower.
  5. Float Valve: It is used to maintain level of water.
  6. Bleed Valve: It is used to control the concertation of minerals and salt.
  7. Body: Body or outer surface of cooling tower is often made up from FRP (fiber reinforced plastic), which protects the internal parts of cooling tower.

Cooling towers can be classified in two types

1) Natural Draught Cooling Tower: In this type of cooling tower, fan is not used for circulating air but here, by enclosing the heated air in the chimney and it will create pressure difference between heated air and surrounding air. Because of this pressure difference air enters in to the cooling tower. It requires large hyperbolic tower, so capital cost is high but operating cost is low because of absence of electrical fan. There are two types of natural draught cooling tower, rectangular timber tower and reinforced concrete hyperbolic tower.

2) Mechanical or Forced Draught Cooling Tower: In this type of cooling tower, fan is used to circulate the air. When power plant runs on peak load, it requires a very high rate of cooling water. To rotate fan, it uses motor with speed around 1000 rpm. Working principle is same as natural draught cooling tower, only difference is that here fan is mounted on the cooling tower. If fan is mounted on the top of the tower is called as induced draught cooling tower which is most popular for very large capacity installation and requires large capacity of fan. So, forced draught cooling tower contains horizontal shaft for the fan and it is placed at bottom of the tower and induced draught cooling tower contains vertical shaft and it is placed at top of the cooling tower.
