G Series Gas Compressors:
This series is often used in natural gas applications where venting is acceptable, and for almost all industrial gases.
The ‘G’ style compressors use three or more sets of gas packings on the piston rod and the packing case can be vented or purged to facilitate leakage control. If allowable any gas leakage past the packings may be vented via tubing to a safe release area.
An inert purge gas, like nitrogen, may be purged through the packing case. If the purge gas is at a pressure above the suction pressure of the process gas, leakage of the purge gas into the process may occur. In some cases this is acceptable and a higher pressure purge is an excellent control option.
If, however, the purge gas is at equal or lower pressure than the suction pressure of the process gas, the process gas may leak into the purge gas. This purge gas must then be vented, flared or safely dealt with in a similar way.
More gas packing sets significantly reduce gas loss and the chance of gas leaking into the local atmosphere. The number of sets is determined by gas type, pressures and purge gas options.

I operate four Hycomp model 2WN61G reciprocating compressors… All four Hycomp compressors have operated reliably for their entire lifetime. The maintenance is straightforward and inexpensive. The factory support is outstanding. I have not experienced any compressor failures in their operating history. Since these compressors supply compressed nitrogen to operate critical components in a nuclear power plant, that reliability has been very important to me. I would highly recommend the Hycomp reciprocating compressors to anyone who desires reliability and endurance in their compressed gas systems.
