All primary components of the Aquatower cooling tower are open to view, which means that maintenance does not get any easier.
Compact and Powerful
Your needs have dictated constant technological improvement. Thousands of Aquatower cooling tower users enjoy the benefits of eight major redesigns and dozens of minor improvements in the past 65 years. For example, PVC film-fill enables the Aquatower to reject more heat per unit size. We also put the air inlet louvers and drift eliminators integral to the fill sheets. This new arrangement saves you fan horsepower by improving airflow through the cooling tower.
Simplified Maintenance
The Aquatower is a maintenance delight! You’ll appreciate the way the Aquatower cooling tower simplifies maintenance. No hidden spray systems, tiny nozzles, or enclosed basins here! You can easily replace and align V-belts from outside the cooling tower.
All primary components of the Aquatower are open to view. You can easily remove any debris from the upper basin or nozzles while the cooling tower is in operation.
Heavy mill galvanizing on all steel components prevents base metal corrosion. Optional stainless steel and fiberglass models enhance the Aquatower with proven corrosion resistance.

The Marley® NC Alpha is a steel structure, splash fill, factory assembled crossflow cooling tower, designed to serve “dirty water” cooling systems which would place the long term operation of a film-fill cooling tower in jeopardy. With shorter lead times and the elimination of stick-built field-assembly labor, the NC Alpha cooling tower offers distinct advantages for industries where dirty water warrants a splash-fill cooling tower.
The NC Alpha is the ideal replacement for splash fill applications previously utilized by the Series 10/15 cooling tower line.
Low Maintenance/Less Downtime
The Marley NC cooling tower is one of the few tower configurations that can be maintained while operating, allowing cleaning and inspecting the distribution system without requiring the pumps to be turned off. Plus, the standard gear drive system can operate for 5 years without an oil change or loss of efficiency. A tremendous advantage over a belt drive system which will require periodic belt replacement and adjustment. All this means less downtime which is especially important for mission or production critical facilities.
Quiet by Design
All Marley NC cooling towers are designed for low sound levels. Models using the Quiet fan option are configured with the best available combination of low noise premium efficiency motors, quiet drive reduction with matched gear sets, and high solidity premium efficiency fans. In concert, these components provide quiet operation for all but the most strict requirements and specifications. Sound attenuation is also an option.
