Power racks EZW – The original

Robust, zero-maintenance, uncomplicated: The cost-effective and reliable alternative to hydraulic and pneumatic solutions.

Originally developed for ventilation applications in greenhouses, and built very robustly indeed, this drive unit is resistant to extremely dirty environments, high humidity levels and severe temperature fluctuations.

For many years, they have been in service in the harshest of industrial environments: malting houses, cement processing machinery, industrial furnaces and in the broadest range of other applications conceivable where local spot loads have to be moved safely and reliably.
