Type RPE
Electric Pilot Heater
Introduction
The type RPE electric pilot heater is used
for reheating gas supplying pressure
reducing regulator pilots.
The type RPE avoids the inconveniences
caused by freezing which occur during
large pressure drops.
Two versions of the type RPE are available:
Electrical Pilot Heater
The type RPE (with a heating element)
is installed in a vertical position and
is affixed to the actuator bolts of the
regulator.
A thermostat and power relay must be
installed in a non-explosive risk zone.
Regulator Bottom Electrical Heater
This version is normally used for relief
lines. The Type RPE is assembled with
four screws to the bottom of the
regulator.
The type RPE can be installed in a
hazardous atmosphere and must be
installed between the pilot filter and the
pre-expansion relay.
The type RPE is in conformity with the
Directive for Equipment or Protective
System intended for use in potentially
explosive atmospheres 94/9/CE. It is
classified under Group II, Category 2.
