WRT Series
WRT Series Cooling Towers Structure
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.
Spares and Components of WDF Series Cooling Towers:
Casing
The tower casing is made of tough fiber-glass 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 the local impact and even if slight damage occurs, local repairs can easily be done. The portion of casing housing fill and eliminator has a round cross section in WRT series & 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 honey comb design with very large contact surface area. The fill splits the air and water in to several streams, increasing the time of contact and also transfer the heat between water and air. The fill is made in modules form and packed in the tower casing without any curves. The air pressure drop through the fill is negligible. The fills are available with flute height of 12mm and 19mm with sheet thickness of 0.15mm to 0.2mm.
Axial Fans
Specially designed energy efficient fans are of induced draught axial type with adjustable pitch. Materials chosen are non corrosive type like plastic, FRP or aluminium alloy. The high efficiency design ensures low running cost and the lowest possible noise level. Fan blade pitch is adjustable and dynamically balanced.
Auxiliary Suction Tank
Auxiliary suction tank is provided from Model no. WRT-11 onwards to facilitate the connections of inlet, outlet, drain & make up pipe connections.
Inlet Mesh
Inlet Mesh is of plastic hexagonal shape to prevent contaminants like leaves, birds etc. entering the cooling tower.
Motors
The special purpose induction motors used in the cooling towers are totally enclosed, flange mounted with extended shaft. They are for 415V, 50Hz, 3phase with ‘F’ class insulation.
Distribution System
The distribution system is uniform & even depends on type of cooling tower shape
Sprinkler System
Automatic rotary sprinkler system made of aluminum alloy or cast steel (optional) material, with rotary head and non clog sprinkler pipes distributes the hot water over the entire space of fill area in WRT series. The FRP pipe eliminators attached to the sprinkler pipes are specifically designed for lower pressure drop and minimizes the drift loss of water.
Fixed Header Pipe System
Fixed header system is made up of non clogging, thick PVC pipes further coated with FRP in WST series requires low pressure to operate and assure uniform water flow with minimal operating head through spray nozzles incorporated in the system which are made from best grade of polypropylene.
Drift Eliminators
Specially designed drift eliminators supported by galvanized frame are for minimizing the drift losses of the water as per shape
