Cooling water returns in a warm state from the process and enters at the top of the cooling tower under pressure to be distributed through the fill pack. Simultaneously, air is drawn in at the base of the tower by the fan and travels upward to mix with the water where some evaporation takes place, removing heat from the remainder. The warm moist air is discharged to atmosphere.

Features :

• Cooling capacities from 50kW to 12, 000kW.
• Body and basin constructed from Z725 galvanized steel.
• High performance, long life axial fan.
• Vertical air discharge at a sufficient distance from the horizontal air intake to prevent air re-circulation.
• Highly efficient drift eliminator limiting water losses to less than 0.001% of the water re-circulation rate.
• Patented fill pack inducing a highly turbulent mixing of air and water for superior heat transfer.
• Superior two pass air intake louver and screen design to minimise water splash out and block sunlight to reduce algae formation. The low pressure drop design results in lower fan energy consumption and operating costs.
• Pressurized water distribution system with sediment preventing sludge rings incorporated within the spray nozzles. Easily removed for maintenance.
• A.C.O.P L8-2000 compliant.

We are manufacturer and exporter of quality FRP cooling towers that are offered in both counter and axial flow models. The FRP towers are widely used in air conditioning plant, induction furnaces/sheet rolling mills, chilling plant/refrigeration, diesel generator set/turbines, injection molding/plastic industries, automobile industries and mechanical and forging industries. These towers are manufactured using high grade material that makes them corrosion resistant, and helps in resisting water borne bacteria and organisms. This is light in weight, which permits roof installation with special reinforcement of any kind. The special construction helps in consumption of less power because of a lesser amount of air resistance to water.

Fanless / Filless Cooling TowerThe Fanless, Filless Induced Draft design has been developed after a detailed research and analysis of the engineering design. This design allows a substantial saving in Power Consumption. Also, the common problems of breakdown and maintenance of Cooling Tower are eliminated to a large extent with this design.

Technical Function

• The Hot water from the heat source is circulated to the inlet header of the Cooling Tower. The inlet header pipes have branches and sub branches covering the internal area of the cooling towers. The non clog nozzles are connected at the outlets of the sub branch piping's.
• At a inlet pressure of 1 - 1.5 Kg/cm2 to the Cooling Tower, the hot waters are atomized to a mist state. The nozzles are self designed to create more pressure thereby converting water into minute atomized particles. From the four sides of the louvers, plenty of fresh air is automatically circulated by the aero dynamic designed FRP louvers. Waters are directed by the special aero dynamic louvers towards the collection sump. The louvers ensure that the water donot spill out of the towers.
• The hot waters, that are in a mist state, comes directly in to contact with the ambient air and the cooling is achieved mainly by, the portion of water, that gets converted to vapors, thus caring away the latent heat of evaporation. Therefore, water gets cooled and in this process, the air gets heated, saturated and thereby caring away some sensible heat from water.

Cooling Tower Selection :Cooling towers are designed and manufactured in many sizes and configurations. Recognizing and understanding the different configurations and advantages is essential for specifying the most cost effective solution for the end user. The purpose of this bulletin is to highlight the differences between crossflow and counterflow cooling towers.

Counter Flow Cooling tower overview :

• The primary task of a cooling tower is to cool water by rejecting heat into the atmosphere. This heat rejection is accomplished through the natural process of evaporation that takes place when air and water is brought into direct contact in the cooling tower. The evaporation is most efficient when the maximum water surface area is exposed to the maximum flow of air in the longest possible period of time.
• Cooling towers are designed in two different configurations, counterflow and crossflow. The specific configuration indicates the direction of the air flow in relation to the water flow. Cooling water distribution and air distribution are designed in a harmonious configuration and are equally important to determine a maximum efficiency in heat rejection.

Counterflow towers

• Counterflow towers use, in general, low pressure spray nozzles to divide the hot water equally over the infill surface in fine droplets. A drift eliminator section above the water distribution rejects all the water in liquid form and keeps this in the circulating system. Only water evaporated in the air leaves the tower with the saturated air. A nozzle distribution is sensitive to changes in water flow thus it affects the over all efficiency.
• The air movement is vertically through the fill in counter flow to the downwards fall of the water. Counterflow towers have in general a smaller footprint than crossflow towers but require a higher pump head due to the typical distribution system with nozzles.
