Description

This Used SPX Marley NC Class Crossflow Cooling Tower Model NC8409U is part of a high-efficiency 4-cell system, offering premium performance for industrial or commercial cooling applications. Each cell is rated at 790 nominal tons, supporting a combined water flow rate of 6,600 GPM or 1,650 GPM per cell.

Engineered with a 12' diameter, 5-blade fan, and powered by a 50 HP, 1800 RPM motor operating at 60 Hz, 230/460V, this cooling tower is designed for high reliability and energy-efficient cooling. It operates with hot water at 109°F, cools it down to 85°F, and manages an entering wet bulb temperature of 76°F—ideal for demanding environments.

Built in 2018, the unit remains modern and in good operational condition, combining the trusted design of SPX Marley crossflow towers with current-generation efficiency.
