PFIR Insertion Regulator

The EnPro PFIR is an insertion Probe Regulator that provides a regulated sample supply to chromatograph's, H2S analyser, gravitometers, calorimeters, moisture analysers, instrument gas take-offs, and other on line analysing equipment

By taking the pressure drop at the tip of the probe, inside the pipe, the Joule-Thompson effect is minimised or eliminated. Thus a dry sample is generated. Essential for on-line analysers.

To assist the reduction of forces generating vortex shedding, the helical transition tube acts an aerodynamic stabiliser.
