Lenze has developed a three-level system of surface and corrosion protection that ensures reliable operation of geared motors in high humidity, atmospheric contamination or outdoor installations.

Available with the G-motion range of geared motors and geared brake motors, the new protection system includes an optimised multi-layer paint finish plus other supporting measures.

Lenze geared motors without any additional protection are resistant to oil, dirt and moisture; these new measures allow well-defined protection that suits most industrial applications.

The three levels of protection offer customers an easy choice to achieve a long and trouble-free life.

The level OKS-S suits indoor heated environments with humidity levels up to 90 per cent.

Here Lenze applies a two-pack polyurethane paint finish with excellent colour stability and weather resistance, suiting corrosion category C1 of the standard EN ISO 12944-2.

Corrosion protection is applied to the output shaft; standard brakes, blowers and encoders are optional.

Resistance to condensation and salt spray is good and proven by testing to the relevant standards.

At the next level, the OKS-M, a higher paint specification, allows use in covered outdoor areas with up to 95 per cent humidity.

The highest level, the OKS-L, suits outdoor use or with high ambient temperatures, as well as atmospheric pollution from oils, solvents and acids.

Here the paint finish is again upgraded and applied to areas not normally coated, for example inside the fan cowl and the motor B-shield.

Fixing screws are zinc coated and cable glands have seal rings.

A corrosion-resistant brake with seals and an IP65 encoder are optional.

The OKS-L level meets category C3 of EN ISO 12944-2.

The Lenze system for surface and corrosion protection is available for motors and geared motors from 60W up to 45kW.

Customers gain the assurance of long-term and reliable operation based on these three well-defined optional levels.
