3.	Motor: Weatherproofed, totally enclosed for less noise and efficient long-term performance.
G.	Water Distribution System: A set of sprinkler pipes and one sprinkler head that is mounted on top of the stand pipe on the cooling tower. Little or no head pressure loss and minimum maintenance.
1.	Models T-25 through T-260: ABS plastic sprinkler head with stainless steel shaft. The sliding part is lubricated by the water.
2.	Models T-270 and Above: Aluminum alloy sprinkler head. Fitted with sealed type bearings to take thrust and radial loads and to ensure that the sprinkler head revolves smoothly.
3.	Sprinkler Pipes: Sturdy PVC material pierced with closely spaced holes allowing thorough distribution of water in a rotating spray covering the entire surface of the filler.
a.	Sprinkler is rotated by the circulating water pressure. There are numerous holes in the sprinkler pipe to allow the water to jet out as the pump impacts rotation.
4.	Efficient operation results from the smooth pumping of re-circulated water through the stand pipe and up into the sprinkler pipes.
5.	A large diameter outlet pipe draws a constant supply of cooled water from the basin to serve the facility.
H.	Air Inlet Louvers: Non-rusting PVC plastic mesh provides easy access to sump while preventing foreign objects from entering water basin.
1.	The round casing design permits maximum air intake regardless of wind direction.
I.	Ladder: Models T-240 and Above: For maintenance and inspection accessibility to fan and sprinkler systems.
J.	Fill Material: Honeycomb heat-embossed PVC formed to permit high heat transfer efficiency. 
1.	Inlet Water Temperature: Up to 125 degrees F (52 degrees C).
a.	Fill Material creates a surface area that allows the maximum dispersion of water and superior cooling effect.
2.	Filling Supports: PVC.
K.	Mechanical Equipment Supports: HDGS.
L.	Tower Support Framework:
1.	Model: T-25 - T-2175: FRP base legs are incorporated with the water basin in a single unit to withstand wind pressure and vibration.
2.	Models T-2200 - T-3000: Hot-dip galvanized steel to resist corrosion and rust.
