WDF/WSF Series
WDF/WSF Series Cooling Towers
- Designed for maximum service life dependability and performance
- Readily adaptable for industrial processes, DG sets & Air conditioning
- Designed for uniform water distribution and optimal heat transfer
- Consumes minimum power due to high efficiency of Axial flow FRP fan sets.
Spares and Components of WDF/WSF Series Cooling Towers:
Structure
The structure of the cooling tower made of the best grade of pinewood pressure impregnated by chromate copper arsenate to prevent it from any bacterial attack. It is bolted and designed for 30 pounds/Sq ft wind load.
Louvers & Casing
Corrugated asbestos cement board casing is applied vertically. Joints are lapped and sealed for water tightness. Corners are covered with FRP corner rolls. Corrugated asbestos louvers are located on wide centres on the sloping louvered walls. They are supported by tower columns and louver support. (FRP casing and louvers can be provided if desired)
Internal Fills
Splash bars are made of preservative-treated wood with a choice of PVC ‘V’ type or ‘C’ type bars.
Hot Water Distribution System
The hot water distribution system is of open gravity type and is constructed from boiling water-proof marine plywood with polypropylene target nozzles.
Target Nozzles
The target nozzles used in the hot water basin are specially designed to deliver uniform water distribution and are highly resistant to temperature and weathering damage. Their use eliminates the need for a separate diffusion deck to provide complete water distribution throughout the fill area. These nozzles operate under gravity.
Drift Eliminators
Specially designed eliminators are made in replaceable modules. Each module can be easily removed, cleaned, and reinstalled quickly. Eliminates drift loss to less than 0.1%.
Fan Drive System
Direct Driven
Fans in smaller models are direct driven on lower RPM motors which are mounted on an MS galvanized fan cylinder covered by FRP segments.
Gearbox Driven
Fans in bigger models are driven by spiral bevel gearboxes of proven design with maximum efficiency. These are mounted on mechanical equipment supports specially designed from hot tubular steel and are hot-dipped galvanized.
Fan
Our cooling towers are fitted with FRP Axial Flow fans with aerodynamic efficiency and significant saving in higher operating cost.
Fan Blades
Fan blades are made up of fiberglass reinforced epoxy resin. These blades are hollow in construction and have been designed with the most efficient aerofoil section. Optimum aerofoil section thickness has been selected to achieve maximum lift and minimum drag coefficient.
Fan Hub Assembly
Fan hub assembly is simply designed for easy installation & minimum maintenance. It is dynamically balanced and made of stainless steel plates, aluminum clamp blocks, cast iron bush, and all hardware in stainless steel for resistance against corrosion.
Fan Cylinder
Our cooling towers are fitted with elevated fan cylinders in HDG steel or FRP material, which enhances air movement, completely eliminating the chance of re-circulation of exhaust air and thereby increasing cooling tower efficiency.
Flow Control Valve
Flow control valves are of heavy-duty cast iron body and stainless steel valve stem ensuring long life and low maintenance. Oversized valve body delivers best velocity dissipation for even water distribution.
Coupling
Couplings are of a heavy cast-iron body and stainless steel and bushes are made of Nylon with HDG Hardware.
Fills Support System
Grid System
Fills splash bars are supported on SS-304 grids which assure positive and permanent positioning and allows splash bars to expand and contracr without crcking, wraping or sagging. Close-packed fills provides maximum wetted surface and water breakup.
Tray System
Our cooling towers are also fitted with "Foster-Wheeler" stake type fills arrangement, comprising of splash bars fixed with transverse stringers, making the fill into removable trays. This system makes an excess of wet surface area and eliminates any chance of fill collapse.
Mechanical Equipments & Accessories
All mechanical equipment used is specially designed and manufactured for cooling tower application. Multiblade fans are of FRP for smooth & energy efficient operation. Adjustable pitch blades allow maximum utilization of applied horsepower.
Structural Plates & Fasteners
The entire cooling tower structure is held by SS-304 U & L plates, bolted with hot-dip galvanized nuts and bolts, along with SS-304 screw shank nails.
