SEW-Eurodrive has developed a purpose-built 2-stage gear unit series solution, the MACC series, specifically for air-cooled condensers (ACC). Air condensers are the preferred solution for dry cooling towers in a range of industries including power stations, refineries, petrochemical plants and even paper mills.
The MACC solution features maintenance brakes, oil filtration on all units and a robust reinforced housing. Internal reinforced bearing systems and custom output shafts have been designed to suit precise client requirements.

The solution is reliable, powerful and quiet. Its efficient design allows it to meet the exact technical specifications of a wide variety of application demands including high torque, fan impeller loads and an extensive speed range including wind milling, low noise levels and reinforced support of motor weights and sizes.
The MACC range offers a high thermal capacity due to a large housing, cooling ribs, optimised oil level and oil circulation as well as a low noise axial cooling fan as an option for increased thermal capacity. In addition, a reliable surface treatment is available for aggressive environmental conditions.
The solution has the benefit of offering all the necessary optional accessories in a manner that is maintenance friendly and which is accessible from the walkway on the fan bridge.
SEW-Eurodrive already has several of these units in operation globally. In South Africa, it recently supplied six MACC series helical gear units to a local electricity utility. “The six units are the largest size in the range supplied to date,” reports Jonathan McKey. “The drop-in solution provides clients with a convenient plug-and-play option in addition to providing improved reliability.”
