For L-force geared motors, Lenze now offers a specially developed surface and corrosion protection system called OKS. The Hamelin specialist in drive and automation technology has put together a scaled range of packages. They include multi-layered surface coatings, components especially resistant to corrosion, and other protective measures. Wherever protection is needed against salt-laden air, subtropical climatic conditions or even rainwater, the corrosion protection program provides the appropriate protection for various weather conditions.

Based on the corrosivity classes of EN 12944-2, the three packages have been tested extensively, including tests with salt-spray. The OKS-S package is resistant to oil, dirt and moisture. OKS-M (medium) is tailored for slightly more arduous ambient conditions – for example for installation in unheated buildings or covered outdoor areas. In industrial atmospheres with moderate air pollution and a high level of humidity, the OKS-L package is the right choice. Geared motors with this level of protection are in use in uncovered outdoor areas as well, for example in conveying systems for bulk materials.
