Pipe Insert Heaters use an ANSI flanged heater or an NPT screw plug heater mounted inside a pipe. These offer you the advantages of direct immersion heaters with the benefit of being able to service the heater without draining the tank. The Incoloy sheathed element(s) inside the pipe are carefully designed for this applicaton, and transfer their heat to the inside pipe wall by convection and radiation. The large surface area of the pipe in contact with your liquid greatly reduces the intensity making the pipe insert heater ideally suited for heating:

- Very viscous materials like Bunker C Fuel Oil
- Temperature sensitive materials like glucose & liquid sugars
- Bulk storage of corrosive Material

SHEATH MATERIALS

	SHEATH MATERIAL Incoloy 800®	APPLICATION WATT DENSITY Watt.in² Incoloy 800 is used for all pipe insert heating applications. Maximum sheath temperature 1400ºF 10-30

TERMINAL HOUSINGS

	Terminal Housings	NEMA 1 Sheet Metal Housing (Intended for indoor use only) NEMA 4 (Standard) Moisture Resistant Terminal Housing NEMA 4X Epoxy Painted or Stainless Steel Moisture Resistant Terminal Housing NEMA 7 Hazardous Location Terminal Housing

BUILT IN THREMOSTAT OPTIONS

	Power Ratings	Up to 240 volts, 25-amp double pole, single throw (DPST) Up to 600 volts, 15-amp triple pole, single throw (TPST)

	Temperature Ratings	160 to 370°C (320-700°F)

	Thermostat Application	Since the thermostat will be located inside the pipe, it will be measuring the internal pipe temperature. The thermostat is intended for high limit purposes and is not suitable for process control.

BUILT IN TERMOCOUPLE OPTIONS

	Sensors	"K" calibration thermocouple for high limit sheath protection. Since the thermocouple will be located inside the pipe, it will be measuring the internal pipe temperature. The thermostat is intended for high limit purposes and is not suitable for process control.

SCREW PLUG AND FLANGED ASSEMBLIES COMPLETE WITH PIPE

	Complete Pipe Heating Assemblies	Screw plug (SPA Series) and Flanged assemblies are available complete with a pipe when installation of a pipe into the tank is not feasible or desirable. The pipe wells are 2” or 2 ½” NPT schedule 40 carbon steel in the standard designs. Stainless steel pipes and connection fittings are available for chemical corrosion for or immersion into food products.
