*compared to other factory assembled single-cell cooling towers

Warm water from the heat source is pumped to the water distribution system at the top of the tower. The water is distributed over the wet deck fill by means of large orifice EvapJet nozzles. Simultaneously, air is drawn in through the air inlet louvers at the base of the tower and travels upward through the wet deck fill opposite the water flow. A small portion of the water is evaporated which removes the heat from the remaining water. The warm moist air is drawn to the top of the cooling tower by the fan and discharged to the atmosphere. The cooled water drains to the basin at the bottom of the tower and is returned to the heat source. The vertical air discharge of the AT design and the distance between the discharge air and fresh air intakes reduces the chance of air recirculation, since the warm humid air is directed up and away from the unit.

Gear Driven Fan

• Standard double reduction gearbox and driveshaft
• Motor located outside air stream

EVAPAK Fill

• Constructed of inert polyvinyl chloride (PVC)
• Resistant to rot or decay
• Capable of water temperatures up to 54.5ºC/130ºF (high temperature fill available)
• Usable as an internal working platform
• Have a flame spread rating of less than 25 under ASTM E84
• Low-fouling fill available for alternate water qualities 

High-Efficiency Drift Eliminators

• Limits the drift rate down to 0.0005% of the recirculating water rate
• Limits the potential of spreading Legionella
• Constructed of an inert polyvinyl chloride (PVC)

Superior Air Inlet Louver and Screen Design

• Constructed of an inert polyvinyl chloride (PVC)
• Water and Sight Tight (WST) design that minimizes splash-out and the potential for algae formation inside the tower
• Framed in steel in easily removable sections

Pressurized Water Distribution System

• Utilizes EVAPCO's EvapJet nozzle for even water distribution
• Constructed of schedule 40 polyvinyl chloride (PVC) pipe and ABS plastic nozzles
• Piping is easily removed for cleaning
• Nozzles are large orifice and have no moving parts, making them practically impossible to clog
