Overview

Built for aggressive media and heat.

Where polymers reach their temperature ceiling, the stainless line carries on — austenitic, acid-resistant grades selected per medium. The carrier is foamed into a single bonded element with the casing, so you get steel's strength with the thermal performance and corrosion-free jacket of the TERMOTECH system.
