Dynamic Reflux Sampler

Clean samples from your caustic, difficult process conditions.  Solve your complex sampling problems. (such as hot, particulate laden, corrosive and otherwise nasty samples in a process).  The DRS2170 is now available with air cooled and liquid cooled to the sample handling systems.




DRS2170 Dynamic Reflux Sampler for gas chromatographs, photometers and other analyzers

The DRS2170 solves complex sampling problems (such as hot, particulate laden, corrosive and otherwise nasty samples in a process for application engineering. The primary sample conditioning occurs in an in-situ fashion. Condensable components are removed and are used to support particulate removal before they can present problems in the sample transport system’s downstream components and the analyzer. The unit is a self-contained sampling device suitable for mounting at or near the process pipeline tap.

Whether the solution is used for gas chromatographs, continuous gas analyzers, photometers or other analyzers with difficult sample conditions, the DRS2170 provides:

  • High sample throughput
  • Clean sample provided to the analyzer
  • Self-cleaning
  • Temperature control precision
  • Optimum control with set-point tuning
  • Hazardous area certification
