Corken’s liquid traps are recommended in all liquefied gas transfer applications or where the climate or process conditions cause condensation of gases in the suction piping. A gas compressor cannot tolerate even a few drops of liquid. Liquid slugging causes severe damage to the compressor and in some cases can destroy it completely. We offer three types of liquid traps that will fit a variety of applications.
If the application conditions involve liquid forming in the suction line during operation or the compressor is unattended, an automatic liquid trap is recommended. The automatic liquid trap has one NEMA 7 liquid-level switch and a drain valve. When liquid level inside the trap reaches a critical level, the liquid-level switch will shut down the compressor before any damage is incurred.
A mechanical trap is useful when liquid is only present during start up. Our mechanical liquid trap comes with a mechanical float assembly and drain valve only.
Applications with a large flow volume due to a long suction line and the compressor is left unattened, our ASME code-stamped automatic liquid trap is recommended. An ASME code-stamped automatic liquid trap has two NEMA 7 liquid-level switches and an alarm, relief valve, pressure gauge, demister pad, and drain valve. When liquid level inside the trap reaches a critical level, an alarm will sound and the liquid-level switch will shut down the compressor before any damage is incurred.
