WSL Series Dual Cell

A larger version of our induced draft, counterflow tower. Towers feature separate cells with a shared basin or separate basins with a flume box or equalizer connection, allowing for independent cell operation. Cooling capacities range from 276 to 1185 nominal tons. All dual cell counterflow towers meet ASHRAE 90.1 efficiency requirements.
