Cathodic protection rectifiers
Rectifiers and complete stations with remote supervision and GPS sync.
Cathodic protection keeps buried pipelines and steel structures from corroding. We build SZK-series rectifiers in batches of thousands — from compact DIN-rail units to 120 A cabinets, air- or oil-cooled, supervised remotely through the NES Control Server web application. They protect infrastructure in Slovakia, across Europe and in Australia.
