Renewed monitoring of cathodic protection stations

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.
