The CT7 provides a thermal barrier for instrument protection between the hot vapors and the pressure instrument

The CT7 makes a valuable contribution to the installation and use of pressure gauges on steam and other hot vapor applications and provides a seal barrier for a gauge or other pressure measuring device.

  • Cost savings of up to 50% against old style ‘pigtail’ siphon.
  • Compact design requires minimum space for installation.
  • Creates a condensate barrier between the live steam process line and the device. Low heat transfer coefficient provides a predictable temperature of the pressure measurement instrument.
  • Forms a barrier to prevent freezing of instruments on wet air lines and acts as a freeze protector for aqueous liquid service.
  • Immediate installation of piping without instruments during construction saves time.
  • Reduces gauge whip by enabling close coupling to process.
