Single-Point Purger Controller is used with Armstrong XR-1501
Series refrigerant purgers fitted with a float and temperature sensor
assembly. This combination provides a simple, effective and efficient
means of removing air and other non-condensable gases from refrigeration
The controller continuously monitors the liquid level and temperature
inside the purger body. When the float switch indicates an accumulation
of gas, and the temperature inside the purger is below the set point,
the purge solenoid will be energized to vent the non-condensables from
the system. The purge light on the controller will light up when the
purge solenoid is energized.
The purge solenoid will de-energize and close when the float switch
indicates all the non-condensables have been purged or when the
temperature inside the purger exceeds the set point.
Armstrong also offers a retrofit package for existing, older
Armstrong systems. Consult the factory or your Armstrong Representative.
