The MULTICOIL heater tubular element with multiple coils and/or thermocouples inside one sheath answers the need for a versatile, innovative tubular multiple coil heater. Watlow's patented method of packaging a thermocouple inside of a heater with one or more resistance coils gives the ability to sense a heater's internal temperature accurately, every time.

Moreover, this is the first tubular heater in the industry with three-phase capability. The three coil, three-phase heater will offer a compact package solution while delivering the full power required in a compact heater package. Previously three separate heaters would have been required to do the same job; therefore Watlow's MULTICOIL heater capabilities save money.

Features & Benefits

Three-phase capability results in one element versus three, lower amperage, reduced installation time and lower overall cost

Multiple coil operations reduces inventory by allowing dual voltage capability

Versatile forming capabilities forms into many configurations

Internal thermocouple construction eliminates contamination buildup around the external sensing tip, reducing the possibility of false readings
