Corrosion Protection – a worthwhile investment

For use in almost all ambient conditions we offer different alternatives for DREHMO actuators corrosion protection.

Corrosion protection K3

This corrosion protection is adequate for actuators installed in closed rooms or outside where the atmosphere is not or occasionally polluted. It consists of a single coat. We use a hard-wearing 2 components-coat. Colours are available on request according to the RAL-colour scale. The standand colour is RAL 5015 (sky-blue).

Corrosion protection K4

For operating ranges where the actuators are exposed to aggressive media (such as sulfureous or saliniferous air), we recommend the use of the superior corrosion protection K4. By using a tripple layer we can achieve an uprated corrosion protection for longer product life. A hard-wearing 2 components-coat is used.

Corrosion protection K5

This corrosion protection is especially recommended for operating areas where the actuators are permanently exposed to aggressive media (e.g. for use in cooling tower). By conventional surface technology the waters' aggressive substances lead to the sub-surface migration of conventional coating systems which causes the corrosion of the aluminium material. By using the corrosion protection K5 a producer durable good is guaranteed. In this connection the tripple coat is made of high resistant 2 components-coat combined with hard-anodic oxidation of the aluminium housing surfaces (galvanic surface transformation).
