Multicoil Tubular Heaters

 
Multicoil Tubular Heaters
The tubular element with multiple coils and/or thermocouples inside one sheath from Watlow® answers the need for a versatile, innovative tubular 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 heaters’ 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.

Product Features

Three-phase capability
  • Results in one element versus three, lower amperage, reduced installation time and lower overall cost
Single-ended (Sensor not available with this package)
  •  Allows for mounting in a 1/2 inch NPT or 3/4 inch NPT fitting with three-phase capability
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; plus, the interior thermocouple eliminates contamination buildup around the external sensing tip, reducing the possibility of false readings
