Dynamic Reflux Samplers

ABB is a leading global technology company and manufacturer of a wide variety of industrial products and solutions in the power and automation sector that enables utility, industry, and transport infrastructure customers to improve their performance while lowering environmental impact.


Dynamic Reflux Samplers

Simplify your analytical sample conditioning design by installing the nearly in-situ DRS2170 at your process tap location. Particulate laden, hot, corrosive or otherwise problematic process streams can be handled upstream of your analytical sample conditioning system with this simple, yet effective addition to your analyzer solution. Remove water and other condensable constituents without having to design reflux systems to return these non-wanted additions back to the process.

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
