Our partners at EVAPCO are always innovating.

Meet the EVAPCO AT Atlas counterflow cooling towers, A cooling tower designed in large, preassembled modules for ease of rigging and installation. As the most energy efficient modular cooling tower on the market, the AT Atlas is unmatched in CTI-certified capacity per cell.

Atlas series cooling towers range in capacity from 1,484 to 2,386 nominal tons per cell, providing up to 60 percent more cooling capacity per cell, while requiring up to 40 percent less fan power per ton of cooling compared to traditional factory assembled cooling towers.

Additional Product Highlights:

• Factory assembled lead times meet field-erected capacities
• Atlas arrives to site pre-assembled in modules and installs in a fraction of the time of field erected solutions
• Reduced overall piping and electrical connections compared to projects with traditional factory assembled cooling towers
• IBC Compliant – Independently certified by the International Building Code to withstand seismic and wind load forces in North America
• Independently certified by the Cooling Technology Institute
• Available with FM Approved construction

Principle of Operation:

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.
