Marley NC
Marley NC
Highest Single Cell Cooling Capacity*.
The NC offers the highest tonnage per cell and the highest ASHRAE 90.1 performance available – up to 2189 tons (9614 kW).
Independently Validated Sound Data.
Marley towers are the only package cooling towers tested per CTI ATC-128 test code by third-party CTI-licensed test agents and certified acoustical engineers. NC sound levels are independently verified to meet published sound levels.
Lowest Drift Rates.
Lower drift means less water escapes the tower, providing cleaner surroundings. The new patent-pending MarKey™ Eliminator achieves the lowest available drift in a crossflow cooling tower.
More Vibration Protection.
New generation mechanical and solid-state vibration switches ensure smoother start up, safe operation and long service life.
Cold Water Basin Inlet Covers.
New optional SunShield™ Inlet Covers protect the cold water basin from sunlight and debris which can contribute to algae growth.
The Marley NC Cooling Tower has set the standard for high efficiency and low maintenance since its introduction in 1968. Our nearly 100 years of cooling tower engineering know-how is utilized so that the NC Cooling Tower you select today provides the broadest range of configurations and the highest cooling capacities available in a package cooling tower.
Available fully factory assembled or for field-erected installation, the Marley NC Cooling Tower incorporates Marley-engineered components specifically designed for cooling tower service with time-tested tower design – a combination that has proven effective in thousands of cooling installations around the globe.
Details
Low Operating Costs: Marley high-efficiency heat transfer media, fans, gravity-flow water distribution and efficient mechanical drive systems work together to offer maximum cooling with minimum power use. Extensive NC model configurations offer selection flexibility and value when evaluating first cost and life cycle cost options.
Quiet By Design: All Marley NC Cooling Towers are designed for low sound levels using high efficiency low sound fans and heat transfer media with low splash noise characteristics. Sound data is developed and tested per CTI ATC-128 guidelines to ensure accuracy and data reliability.
- The Quiet Fan option provides sound levels that meet intermediate sound level requirements. Models are configured using premium efficiency motors, quiet gear drive reduction with matched gear sets and high solidity premium efficiency fans.
- The Ultra Quiet Fan option and Sound Attenuation components are designed for the most extreme sound level requirements.
Long Life Construction: Rugged G235 heavy mill galvanized steel is standard; Series 300 stainless steel is an optional upgrade to the tower structure and includes a 5-year limited warranty. Marley Cooling Towers are manufactured in ISO-certified facilities, attesting to our commitment to comprehensive quality processes and systems.
Performance for All Seasons: The Marley NC Cooling Tower is designed to operate year round as specified and will adapt to various energy-management approaches.
Low Maintenance/Less Downtime: The Marley NC Cooling Tower can be maintained while operating, which translates to less downtime for mission-critical facilities.
- The water distribution system may be inspected and cleaned without turning off the pumps.
- The standard gear drive system is designed to operate a full five years without oil change or efficiency loss; comparable belt-drive systems require more frequent adjustment and replacement.
