A direct-drive, variable-speed solution is part of the design of a new cooling tower from Baltimore Aircoil Co. The Baltimore-based company released its Series 3000 with an EnduraDrive fan system that reportedly provides reliability and energy savings with low maintenance costs.

According to BAC, the fan system offers a 10 percent reduction in energy costs and a 90 percent reduction in maintenance costs compared to a gear-drive system, with 100 percent reliability on the transmission system. The fan-system-equipped cooling towers are available with capacities from 171 to 1,446 nominal tons in a single cell with up to 4,500 gal/min for process applications. Multiple-cell units also are available.
