Mustang® P53® Sample Conditioning System

The Mustang P53® Sample Conditioning System is an integral component to provide an Analytically Accurate® solution for natural gas sampling applications.

The P53® Sample Conditioning System solves the problem of hydrocarbon liquid condensation from Joule-Thomson cooling in natural gas analysis systems. High pressure natural gas samples are transported at a temperature well above the expected hydrocarbon dew point, which is maintained throughout the pressure reduction process, delivering a representative sample to the analyzers.

The Mustang P53 is available with either the Mustang® Heated Regulator or Mustang® Joule-Thomson Heated Regulator, used in combination with a heated liquid block and is designed for use with integrally controlled, remote Mustang Pony® enclosure products.
