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.
An 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 30oF 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.
