ANTI-CORROSION

Great care should be taken when choosing materials in areas where there is a high risk of corrosion such as industrial use.

All casing parts can be powder coated to enhance corrosion resistance, or a stainless steel casing can be selected. All bearings are life-time lubricated and extra sealed for extended life. Vital parts such as bearing components are coated with tectyl for enhanced corrosion resistance.

Epoxy-coated foil (OC) should be selected. Epoxy-coated foil provides extremely effective protection against corrosion. Seawater-resistant foil (OK) with magnesium content is available; an alternative to epoxy-coated foil, it provides excellent corrosion protection.

In maritime environment there’s a request of increased corrosion protection, both for parts and media. Östbergs standard marine casing is in stainless steel and rotor media in OM for sorption performance and OK for sensible performance. Östberg standard OM for marine application have passed test with non-corrosion for a period of 10 years.
