WRT Series Round FRP Cooling Tower - Compact Industrial Cooling from 5 TR to 500 TR
WRT Series Cooling Towers
The WRT Series Cooling Towers are designed with a robust and efficient round-shaped structure made from high-quality fiber-reinforced plastic (FRP), ensuring durability, corrosion resistance, and long service life. These towers utilize a uniform water distribution system with an automatic rotary sprinkler that evenly spreads hot water across the PVC honeycomb fills, maximizing heat transfer efficiency.
The fills are engineered to provide a large contact surface area, enhancing cooling performance while maintaining minimal air pressure drop. Equipped with energy-efficient induced draught axial fans and reliable induction motors, the WRT series ensures low noise operation and reduced running costs.
Additionally, features like FRP drift eliminators, inlet mesh for contamination control, and optional water collection sump make the system highly efficient, easy to maintain, and suitable for various industrial cooling applications.
The Wetpoint WRT series is a round FRP induced-draft cooling tower manufactured in Gwalior, India, available in capacities ranging from 5 TR to 500 TR. It is designed for industrial and HVAC installations where space is limited. It delivers reliable, low-maintenance cooling, and its compact round shape allows it to fit in locations where rectangular towers cannot be installed.
Key Features of the WRT Series Round Cooling Tower

Automatic Rotary Sprinkler – Evenly distributes hot water over PVC honeycomb fills without clogging, even in hard-water areas.
PVC Honeycomb Fills – Large contact surface area with negligible air pressure drop for maximum heat transfer efficiency.
Induced Draft Axial Fan – Energy-efficient, adjustable-pitch FRP blades with dynamic balancing for quiet and cost-effective operation.
FRP Drift Eliminators – Minimize water drift loss to protect surrounding equipment and reduce water wastage.
IE2 and IE3 Motor Options – High-efficiency induction motors that reduce power consumption and operating costs.
Optional Trickle Fills – PP material combining film and splash fill characteristics; ideal for applications where cooling water contains high suspended solids or carries a risk of contamination.
Industries and Applications – Where WRT Series Cooling Towers Are Used
The WRT series round cooling tower is the ideal choice where space is limited and continuous, low-maintenance cooling is required.
Plastics and Injection Molding – Cooling hydraulic oil and molds in injection molding machines. Its compact, round design allows it to fit right next to the machine on the factory floor.
Hospitals and Healthcare – Quiet rooftop operation for HVAC chiller plants and air-handling units, where both low noise levels and reliable performance are essential.
Commercial Buildings – Central plant cooling for offices, malls, and hotels, where multiple units utilize limited rooftop space.
Machine Tools and CNC – Controlling coolant and hydraulic oil temperatures for CNC machining centers. Lower-capacity WRT models (5–40 TR) are perfect for single-machine installations.
Chemical and Process Industries – Cooling batch reactors and condensers. Optional trickle fill media can handle water with high TDS and suspended solids.
DG Set Cooling – Dissipating heat from diesel generator sets in hospitals, data centers, and industrial backup power systems across India.
Spares and Components of WRT Series Cooling Towers:
Casing
The tower casing is made of tough fiberglass reinforced plastic (FRP) and has sufficient structural strength to withstand high wind velocities and vibrations. UV-stabilized resin is used with gel coat for longer life. It is resistant to local impact, and even if slight damage occurs, local repairs can be easily done. The portion of casing housing fill and eliminator has a round cross-section in WRT series and square in WST series. The water collection sump (optional), also of FRP, is leak-proof and avoids water spillage.
Fills
The fill is rigid Polyvinyl Chloride (PVC) and is of honeycomb design with very large contact surface area. The fill splits air and water into several streams, increasing contact time and improving heat transfer between water and air. The fill is in module form and packed in the tower casing without any curves. Air pressure drop through the fill is negligible. Fills are available with flute heights of 12 mm and 19 mm, with sheet thickness from 0.15 mm to 0.20 mm. Optional trickle fills made of premium quality PP material are also available, offering a combination of: Film fills (for thermal efficiency) Splash fills (for resistance to fouling) These are suitable for applications where water quality is poor with high suspended solids, reducing clogging and fouling.
Axial Fans
Specially designed energy-efficient induced draft axial fans with adjustable pitch are used. Materials are non-corrosive such as plastic, FRP, or aluminum alloy.
High-efficiency design ensures low running cost and minimal noise. Fan blades are dynamically balanced.
Motors
Special-purpose induction motors used in cooling towers are totally enclosed, flange-mounted with extended shafts. Specifications: 415V 50 Hz 3-phase ‘F’ class insulation High-efficiency motors (IE2 & IE3) are available as optional upgrades.
Drift Eliminator
Specially designed eliminators supported by a galvanized frame to minimize water drift losses..
Round Type
Round-shaped cooling towers made of PVC sheets in WRT series.
Distribution System
Sprinkler System Automatic rotary sprinkler system made of plastic, aluminum alloy, or cast steel (optional). Features: Rotary head with non-clog sprinkler pipes Uniform hot water distribution over fill area (WRT series) FRP pipe eliminators reduce pressure drop and minimize drift loss
Auxilary Suction Tank
Provided from Model No. WRT-II onwards to facilitate inlet, outlet, drain, and makeup pipe connections.
Inlet Mesh
Plastic hexagonal inlet mesh prevents contaminants such as leaves, birds, etc., from entering the cooling tower.
Supporting Structure
Tower supporting structures are fabricated from mild steel angles, channels, rods, and pipes, all hot-dip galvanized for corrosion protection and longer life. Optional: FRP pultruded profile structures can replace MS galvanized structures. These include FRP pultruded angles, channels, and pipes, offering strong, corrosion-proof solutions for cooling tower structures.
Why Choose Wetpoint WRT Series? Built for Indian Industrial Conditions
Same cooling power in a compact footprint. The circular design occupies up to 30% less space compared to rectangular towers – crucial when space is limited on rooftops or in plant rooms.
Constructed entirely from FRP; no risk of corrosion. The casing, fan blades, and drift eliminators are all made of FRP. There are no painted metal surfaces prone to deterioration in India’s hot and humid climate.
The rotary sprinkler never jams. Unlike fixed nozzle systems-which are prone to scale buildup from hard water- the automatic rotary sprinkler distributes water evenly regardless of water quality, ensuring low maintenance and uninterrupted operation.
IE2/IE3 motors save energy. These high-efficiency motors reduce electricity costs and comply with BEE energy efficiency guidelines for industrial motors.
