Hollow Type Axial Hollow Type Axial Fan
Airfoil-shaped hollow blade fans are made from Aluminum extrusion alloy. Fan hubs are fabricated from hot-dip galvanized (HDG) circular plate with epoxy coated cast iron core and Aluminum blade camps. The fan blades are adjustable in pitch to allow for maximum utilization of rated horsepower and optimum performance. High efficient lower tip speed and light weight design ensure low power consumption and low noise level, thus and guarantee 100% performance.
Transmission System
The fan motors are TEFC type with IP55 weather proof, Class E insulation. Fans are driven by vee belt and the speed can be adjusted by changing pulleys to meet different requirement. By locating the motor on top of fan stacks, the vee belt lengths are shorthen thus ensure linger belt life. Motor mounted in the outside air stream and with gear driven system are also available upon request.
Distribution System
Distribution System
Open gravity fed water distribution basins with removable cover are made of Stainless Steel (SS304 or SS316) and are designed for non-clogging operation and ease of inspection. Special design diffusion decks are placed on top of filler as a re-distribution layer to ensure full coverage of filler.
High Efficient Filler High Efficient Filler
Fillers are vacuum formed of 0.4mm (1/64”) thick PVC film. Filler sheets configuration incorporates sloped flutes in both air intake and outlet sections and are high efficient wet deck media. The honeycomb shaped air intake louver section contributes minimum resistance to airflow and prevents ingress of foreign matters. The sloped flutes in the outlet section of filler sheets act as the primary drift eliminators to reduce droplets escaping through the exhaust air stream. Primary drift eliminat or ensures drift loss less than 0.005% of circulating water flow. The wet deck media with continuous triangular pattern is specially designed to provide maximum air/water contact and lower resistance ensuring high efficient heat transfer.
Casing Panels and Cold Water Basin
Casing Panels and Cold Water Basin
Casing, basins and fan stacks are made of FRP. The smooth and attractive gel-coat is applied on exterior surface for UV protection, chemical resistance and long life. It is light in weight and makes easier for assembly and transportation. Hot-dip galvanized (HDG) or all Stainless Steel (SS304 or SS316) casing and basins instead of FRP are also available.

Sump Tank
FRP cold water sump tanks contain all connection fittings and make inspection or maintenance of fittings easier. Depressed sump tanks provide basin depth and less chance of pump cavitation.

Steel Structure
All supporting steel members are hot-dip galvanized (HDG) to minimize rust forming and corrosion , ensuring long service life. Stainless steel (SS304 or SS316) hardware members are also available upon request.

Inspection Door
Inspection door is furnished to provide convenient access to the interior for inspection, maintenance, adjustment of float valve, cleaning of the lift-out strainer and flushing of the basin
Perimeter Handrail and Safety Caged Ladder Perimeter Handrail and Safety Caged Ladder
HDG sturdy and stable perimeter handrail on top of tower and caged ladder provide safety access and walkway for maintenance and inspection. Stainless steel handrail and ladders are also available.
