Cable Type Heaters have initially been developed and used for the safe operation in fertilizer plants. However nowadays, they cover a large range of applications due to their modular construction and minimum space requirements. They are suitable for heating up nearly all gases and liquids or superheating steam. They are mainly used in hazardous areas. Especially when processes require a combination of high power (in the MW range) high pressure and temperatures of up to 550°C cable type heaters are the means to choose.
