The Bühler Technologies GAS 222.15 ANSI/CSA Heated Gas Sampling Probe is a specialized extraction unit engineered and certified specifically for North American industrial standards by Bühler Technologies (Germany). Built in full compliance with ANSI B16.5 flange specifications and CSA (Canadian Standards Association) safety and electrical standards, the GAS 222.15 ANSI/CSA serves as a rugged primary sampling interface for Continuous Emission Monitoring Systems (CEMS) and online process gas analyzers.

A core engineering highlight of the GAS 222.15 ANSI/CSA is its integrated self-regulating electric heating system. By maintaining a constant elevated probe body temperature between 180°C and 200°C (356°F – 392°F), the probe prevents water vapor fallout and acid dew point condensation when sampling corrosive flue gases loaded with SO2, NOx, HCl, or HF. This safeguards downstream heated sample lines and analyzers against corrosive degradation and filter element blinding.

Furthermore, the unit features an integrated mechanical shut-off valve (ball valve) built directly onto the probe housing. This isolation valve allows maintenance personnel to isolate the sample line directly at the process stack flange without interrupting main plant operations. Filter element inspection, cleaning, or replacement can be performed safely and rapidly without exposing technicians to hazardous, toxic, or high-pressure process gas streams.

Constructed from heavy-duty corrosion-resistant materials including stainless steel 1.4571 (SS316Ti), Hastelloy, or PTFE-coated components, the GAS 222.15 ANSI/CSA includes a high-capacity particulate filter element and a backpurge connection for automated compressed air blowback cleaning. Manufactured 100% in Germany to strict ISO and CSA quality standards, this unit represents the premier choice for EPC contractors and international projects in petrochemical refining, power generation, and chemical processing.
