Purge Control & Monitoring Systems
Purge Control systems control and monitor the flow of buffer gas to a compressor packing case. A packing case contains sealing rings, which act to keep the compressed gas in the cylinder from migrating down the compressor rod. This equates to compressor efficiency, safety, and enables the compressor cylinder to operate without exceeding air quality emissions standards. Purge Control systems enable the operator to quantify the amount of leakage past the rings and which rings in the packing case are leaking. Purge Control panels are normally used in EPA non-attainment areas or where process gas leakage presents a health safety hazard to personnel.
