The Mustang® Joule-Thomson Heated Regulator (MJTHR) is a four-stage pressure regulator designed to compensate for Joule-Thomson cooling during sample extraction. With a ratio controlled multi-piston design, the MJTHR ensures the first three stages are always functional, even with fluctuations to inlet pressure.
A MJTHR located downstream of a sample probe permits a 4-stage pressure reduction without distorting the composition of a vapor sample. Gas sample integrity is maintained by heating it to at least 30°F above the expected hydrocarbon dew point.
When used in combination with insertion probes, the MJTHR is the most practical means for conforming to the API 14.1 and GPA 2166 standards.
