MULTICOIL™ Heaters 

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:

Features Benefits
Three-phase capability
  • Results in one element versus three, lower amperage, reduced installation time and lower overall cost
Single-ended
  • Allows for mounting in a 1⁄2 inch NPT or 3⁄4 inch NPT fitting with three-phase capability
  • Sensor is not available
Multiple coil operations
  • Reduces inventory by allowing dual voltage capability
Versatile forming capabilities
  • Forms into many configurations
Internal construction with sensor
  • Allows space savings because drilling and tapping of flange is unnecessary
  • interior thermocouple eliminates contamination buildup around the external sensing tip, reducing the possibility of false readings
