Safe and reliable drive solution for dry cooling towers

Many industrial production processes require cooling water or cooling air in order to ensure safe operation. For example, refineries, petrochemical production plants and paper mills need to employ systems and processes that ensure efficient temperature regulation. The components of air cooled condensers (ACC) are also exposed to these special operating conditions.

We have designed the MACC series helical gear unit specifically for this application. These industrial gear units and the associated components are designed for ambient temperatures between -20°C and +40°C.

We individually customize the scope of delivery of this two-stage series depending on the intended application and the customer requirements. All required options can be accessed via the gear on the fan bridge. This industrial gear unit series is a reliable and powerful solution consisting of quality components. Another benefit of the MACC series is its quiet operation.

A durable housing and flexible bearing arrangement for numerous application requirements (such as a high torque) always make our MACC industrial gear unit your first choice. Benefit from our comprehensive experience as a leading manufacturer of industrial gear unit solutions.
