When you purchase a Marley cooling tower, you are choosing a product built with Marley engineered components – designed to not only perform their individual functions, but to work together to optimize overall system performance. And because Marley designs and manufactures exclusively for cooling towers, Marley parts are among the highest quality replacement products, providing years of service with minimal maintenance.
Fan gearducer and the fan itself determine cooling tower performance and affect heat transfer efficiency. Marley gears ensure reliability and meet the conditions for continuous operation in accordance with AGMA and Service Factor 2.0.
Most Marley gearboxes are covered by a five-year warranty and oil changes are required every five years (provided annual oil analysis indicates good physical and chemical properties).
The heat exchanger, also known as a wet surface, packing, film fill, or splash fill is carefully selected to meet the specific operating conditions of each installation. A specific heat exchanger fill must be chosen for the specific application (water quality) of the cooling tower, otherwise the performance will be degraded. The choice of packing depends on the water flow and its fouling factor. Only the tower manufacturer is able to provide the right packaging and can guarantee the correct operation of his tower.
