Condumax Dew-Point Analyzer CD603 Michell
Automatic online hydrocarbon and water dew-point analyzer
The Michell CD603 – Condumax Dew-Point Analyzer is specifically designed for continuous and automatic measurement of the hydrocarbon and water dew points in processed natural gas. Built on over 50 years of expertise in delivering analyzers to the global oil, gas, and petrochemical industries, it offers proven reliability and performance.
The system features a combined hydrocarbon and water dew-point sensor cell along with control electronics, all housed in an Exd-rated enclosure. Additionally, an optional gas handling panel is available to condition the sample gas before it enters the analyzer. The Michell CD603 – Condumax Dew-Point Analyzer is intended for installation near the process sample point for optimal functionality. It is certified for safety and compliance under ATEX, UKEX, and IECEx standards.
Suitable Applications:
- Natural gas processing
- Gas quality measurements at custody transfer
- Transmission pipeline monitoring
- Confirmation and control of fuel gas ‘superheat’ to turbine power plant
Key features:
- Fundamental cooled-/chilled-mirror dew-point measurement principle
- Fully automatic identification of both water and hydrocarbon dew point
- Greater than 65 ˚C (117 °F) measurement depression range
- ±0.5 ˚C (±0.9 °F) hydrocarbon dew-point accuracy
- IECEx, ATEX, cQPSus and UKEX certifications
