 COMPRESSED AIR PRODUCTION 

THE OPTIMAL PRODUCTS FOR YOUR COMPRESSED AIR PRODUCTION APPLICATION

In the field of turbomachines, the system's efficiency can be continuously improved by increasing the system speed or omitting the gear. Hence, it is necessary to use appropriate high-speed motors instead of the slowly rotating standard motors.

Standard frequency converters are not capable of driving high-speed motors adequately as they do not provide the necessary high rotating field frequency on their own, but only with expensive additional equipment like sine-wave filters.

Frequency converters by SIEB & MEYER are especially developed for the operation of high-speed motors. They provide the necessary rotating field frequencies and ensure a low motor heating by means of special control technologies without additional sine-wave filters. The motor heating has a significant impact on the system's efficiency and the service life of motors and bearings.
