Ceramic heating cartridges are dynamic heating elements where the functions of heating and temperature control are combined in one product. A PTC heating element is embedded in a silicone compound with excellent heat transfer coefficient and electrical insulation. The products are suitable for a wide range of applications and are extremely efficient, compact and reliable. Supply voltage is 110-240Vac/dc or 12-24Vac/dc with a maximum power of up to 200W. The applications include keeping mechanical parts frost or ice-free in industrial installations, automotive, wind turbines, but also as valve heating, grip heating, etc.
