Construction N/A
  • Basic construction:
    • 1" or 1 1/4" pipe fitted with a pipe "T" to fit a screw plug heater
    • Insulated pipe with 1 1/4"- 1 1/2" of insulation protected by a steel casing of 20 ga.
  • Supplied units:
    • Without thermostats
    • With general-purpose, moisture resistant, or explosion-proof terminal housings
  • If the outlet liquid or gas temperature is above 150ºC (300ºF):
    • Take the farthest end from the terminal box as the outlet
  • If the outlet liquid or gas temperature is under 150 ºC (300 ºF):
    • Take the outside threaded connection as the system inlet
