Weldon Engineers (India)

We are manufacturing a premium range of POLO FRP Cooling Tower by using technically advanced mechanism to improve the quality of products. Made from quality approved raw materials, these are known for their compact design, corrosion resistance and ease of maintenance. Our collection is capable to render the varied requirements of various areas such as chemical plants, power stations, oil refineries and building cooling.

POLO FRP induced draft round bottle shaped Cooling towers ranging from 5 TR to 500 TR capacities.

In FRP cooling towers production a special composition of raw materials are selected to withstand corrosion, to resist water borne bacteria’s and organisms & is light in weight which permits roof installation with special reinforcement of any kind. Vertical induced draft counter-flow design permits installation in any direction with freedom. It consumes less power (energy) overall because of less area.

Salient Features:

Casing : Cooling Tower Casing is made of selected grade materials of tough Fibre Glass Reinforced Polyester & resins, etc. Additional embossing is done for extra strength in case of big cooling towers.

Fill : Honeycomb & ring type P.V.C fills are used for extended contact area having a high heat transfer efficiency. The crossing of air & water streams in close proximity which creates a diffused turbulence conducive to evaporation & efficient heat transfer.

Water Basin : It is completely leak proof which avoids spillage & seepage of water. It is of deep sump design to ensure maximum water level at all times & made up of FRP with additional stiffening to take care of extra water weight. However RCC basin is recommended for capacities 300TR and above.

Sprinkler : Specially designed rotary sprinkler head is made of aluminium alloy to avoid corrosion, also fitted with sealed ball bearings to take care of thrust & radial loads. S.S. & Brass sprinklers are also provided at an extra cost.

Fan : Fan cast aluminium alloy fan is of aero dynamic designed axial flow type to achieve high efficiency. FRP fan set can also be supplied on request at extra cost.

Drift Eliminator : To reduce carry out losses through entrainment of moisture drops in the stream by specially designed multiblade rotary drift eliminator made of FRP sheets/aluminium. Additional PVC eliminator is provided in large capacity cooling towers.

Motor : Special low RPM totally enclosed motors of Vertical, Flange type with enlarged & threaded shaft and sealed top is supplied with the cooling tower. The motor is also weather proof and in IP-55 construction.

Supports & Hardware : All components like tower supports, motor supports, leg supports, etc. are either hot dip galvanised or epoxy coated. Hardware is Galvanised Steel.

Stainless Steel or Phosphor Bronze hardwares can be supplied on request at extra cost.

NOTE : Dimensional & other engineering data available with proposal/quotation.

Principle of Cooling Towers :

Square type cooling towers operates according to the counter flow principle. The water to be cooled is connected into the tower at the top in main header pipe and is distributed by branch pipes with splash cap (nozzles) with a low pressure drop, and flows down, in the form of a thin water film and small droplets, over the largest possible fill surface for the heat transfer.

The water falls through the fill and is collected in a FRP basin at the bottom of the tower. The atmospheric air is sucked in through the opening for air inlet on all sides at the lower portion of the tower and moves up through the PVC fill. The air moving up cools the falling water. Here the transfer of heat takes place by evaporation and direct contact. The air inlet is covered by PVC Mesh for free flow of air.

Selection of materials :

The selection of materials for the POLO S Series cooling towers is based on the requirement that they must be completely resistant to corrosion and chemicals. This has been achieved through the exclusive use of PVC, polypropylene, fiberglass reinforced polyester (FRP) and hot dipped galvanized steel for supports.

Salient Features :

• Casing, Basin, Fan deck and Fan stack in corrosion-resistant and fire-retardant FRP
• Hot dip galvanized supporting structural.
• Fill material of PVC (max. temp. 60 Degree C).
• High efficient axial flow Fan with Aluminium / FRP blades and cast aluminum alloy hub.
• Drift eliminators of PVC extruded ‘C’ & ’S’ type (drift percentage shall not exceed 0.05 of circulating water flow).
• Water distribution system with PVC pipe and PP splash cap (nozzles).

Advantage :

• Energy efficient - use of high efficient fill, and nozzles with a low pressure drop.
• Durable - use of high quality materials.
• Guaranteed performance - use of PVC fill.
• Aesthetic looks - use of FRP panels.
