Multicoil Heaters
Multicoil HeatersThe multicoil heater from Watlow combines multiple coils and thermocouples, creating a tubular heater with precise temperature measurement and quick installation. It's the first tubular heater in the industry with three-phase capability. By providing the ability to go from single-phase to three-phase in a compact package, the three-coil, three-phase heaters offer a lower amperage solution while delivering full power. The new, patent-pending method of packaging the thermocouple inside the heater sheath with one or more resistance coils gives you the ability to accurately and responsively sense the heater's internal temperature. Multicoil tubular heaters can be formed into most configurations to fit your heating needs.
