CPI 192 material packing was selected for this application and the packing cooling system was removed. The MTBF increased by 49%. CPI removed the cooling system in 31 compressors after this upgrade in this plant.
Upgrading to CPI polymer alloy packing rings:
Eliminates the potential safety risk of gas leakage into the cooling system
Problems with re-cutting O-ring grooves during reconditioning are eliminated
Results in more reliable packing performance and life
Avoids condensation due to the water and gas temperature differential
Saves water – up to 15 l/min (4 gal/min)
