Pipe Insert Heaters offer you the advantages of direct
immersion heat, and the ability to service the heater without
draining the tank.The Incoloy sheathed element inside the
pipe is carefully deigned for this application, and transfers
its heat to the inside pipe wall by convection and radiation.

greatly reduces the watt density (watts/in

Low Liquid Protection

To prevent Low Liquid failure,one of multiple heaters
should have a built-in thermocouple, series PFHK, and this
heater must be mounted slightly higher than other heaters
in the tank. When a Low Liquid event happens the air
temperature inside the pipe rises dramatically and the
thermocouple sends the temperature signal to your
remote mounted high limit control for shutdown.

SPA series pipe heaters come complete
with a mild steel pipe well

Low Liquid Protection

To prevent Low Liquid failure,one of multiple
heaters should have a built-in over heat
protection. This heater must be mounted
slightly higher than other heaters in the tank.
When a Low Liquid event happens the air
temperature inside the pipe rises dramatically.

Low Liquid Protection Options

1. Built in "K" thermocouple option,
ies SPAK.

ser

2. Built in mechanical high limit control,

series SPAHL. Typical temperature setting is
700°F (370°C). The standard control is a
DPST 25amp, 240 VAC. An optional 600 volt,
15 amp TPST control is available.

The built in high limit control has no

contact with the liquid you are heating

and cannot be used as a thermostat to

ontrol your tank temperature.
