설명These convection heaters and contact heating elements are based on PTC (Positive Temperature Coefficients) technology. A wide range of types with different designs and performances for various applications are available. This product line is distinguished by design characteristics: limited temperature of external profile through thermal decoupling. Optimized convectional heat transfer through chimney effect. Self-regulation through PTC technology. Approved safety on the basis of given temperature limitation. High reliability. No switching components.
