Resistant to mechanical damage


This type of heaters are manufactured in protective tubes made of acid-proof stainless steel. They are delivered with protective caps and connection cables. The main advantage is the possibility of changing the ceramic cartridge without changing the protective tube. They are used for heating of fluids in electroplating baths and tanks. The heaters are immersed directly in working solution.
Stainless steel protective tube provides stability of heater when immersed in aggressive fluid. They are resistant to mechanical damage and can operate short term without fluid and in case of voltage changes. Stainless steel tubes are resistant when operating in alkaline environment. Sulfuric and hydrochloric acid can damage stainless steel tubes.
