ABB Dynamic Reflux Sampler DRS2170

The ABB Dynamic Reflux Sampler DRS2170 is a specialized automatic sampling system designed for collecting representative samples of hydrocarbon liquids and similar process fluids in hazardous environments, such as oil and gas, petrochemical, and refining industries. It operates on the principle of dynamic reflux, ensuring minimal sample alteration by maintaining pressure and temperature conditions close to the process line. Key features include explosion-proof construction suitable for Class 1 Division 1 areas, pneumatic actuation for reliability in remote or harsh conditions, and integration with control systems for automated operation. Advantages over similar products include high accuracy in sampling volatile liquids, reduced maintenance due to robust stainless steel components, and compliance with standards like API MPMS for custody transfer applications. Drawbacks may include higher initial cost and the need for compressed air supply. This unit, manufactured in 2013, appears used but in good condition based on visual inspection, with attached components like an Adalet enclosure, pressure gauges, valves, and a digital display. It excels in applications requiring precise, contamination-free sampling, offering better repeatability than manual methods.
