Marley AquaTower cooling towers are factory-assembled, induced-draft crossflow units designed to reject heat from circulating water through evaporative cooling.
This 2019 Marley AquaTower Model AQ492G1BAF features an approximately 28 nominal ton cooling capacity, a 36-inch diameter fan, 2 HP motor, PVC film fill, integral louvers, and drift eliminators.
Description
Available for sale is a used 2019 SPX Marley AquaTower cooling tower, Model AQ492G1BAF, designed for commercial and industrial heat rejection applications.
Marley engineering data for the 492G configuration lists approximately 28 nominal tons of cooling capacity, based on the following operating conditions:

Hot water temperature: 95°F

Cold water temperature: 85°F

Entering wet-bulb temperature: 78°F

Water circulation rate: 3 GPM per nominal ton

At these nominal rating conditions, the corresponding circulating water flow is approximately 84 GPM.
The cooling tower features a factory-assembled induced-draft crossflow design. This configuration draws air through the cooling tower fill while circulating water moves downward through the heat transfer media.
The unit includes PVC film fill, designed to provide surface area for evaporative heat transfer, along with integral louvers and drift eliminators to help manage airflow and minimize water droplet carryover.
Air movement is provided by a 36-inch diameter fan driven by a 2 HP motor, rated 208–230/460V, 3-phase, 60 Hz, at 1,750 RPM.
The cooling tower includes 4-inch inlet and outlet connections for integration into compatible recirculating cooling-water systems.
Overall dimensions are approximately 72" long x 48" wide x 90" tall, providing a compact footprint for the stated nominal cooling capacity.
Manufactured in 2019, this Marley AquaTower is identified by Serial No. 10183156-A1.
Potential applications include HVAC cooling, industrial process cooling, heat exchanger systems, compressor cooling, chiller condenser-water systems, and other compatible commercial or industrial heat rejection applications.
