Hydrogen Control Unit – D-UG 660

DURAG GROUP

Self-monitoring and fail-safe control unit for monitoring gas, oil and coal flames
Suitable for intermittent and continuous operation
Optional parallel operation of two flame sensors in any combination
Three different settings supported for various modes
Easy-to-read LCD display for operational status

The D-UG 660 DURAG is a self-monitoring and fail-safe control unit designed for monitoring gas, oil, and coal flames using DURAG UV, UV+IR, or IR-flame sensors, primarily in multi-burner applications. It supports both intermittent and continuous operation, and offers the option to operate two flame sensors in parallel (UV/UV, UV/IR, or IR/IR). The unit features a plain text display that continuously shows operational status and settings, and provides flame intensity and signal outputs via two current outputs (0/4 ... 20 mA) for further analysis. It is certified for various industry standards and is used in power stations, chemical industries, refineries, cement plants, waste incinerators, steam generators, and heating plants. The D-UG 660 DURAG is designed for reliability and safety, with a plug-in module (21HP and 3RU) for 19-inch racks (IP00) and a range of accessories for optimal performance and safety.

DURAG GROUP DURAG GROUP, a German gas analysis and measurement technology company, supports hydrogen purity monitoring through its subsidiary AP2E's ProCeas gas analyzers, which have been developing hydrogen industry solutions since 2015 and participated in the EU-funded MetroHyVe research project for controlling hydrogen purity per ISO 14687:2019. The ProCeas gas analyzer, based on patented OFCEAS (Optical Feedback Cavity Enhanced Absorption Spectroscopy) technology combined with low-pressure sampling (LPS), monitors trace-level impurities such as CO, HCHO, NH3, H2S, COS, and H2O at hydrogen refueling stations, providing real-time contaminant detection compliant with ISO 14687, EN 17124, ISO 19880, and Northern Lights CCUS specifications with no drift and no recalibration required. SGS France's laboratory in Harfleur uses ProCeas devices to monitor hydrogen purity for mobility applications (grade D, 99.97% purity), quantifying 14 different impurities from ppb to ppm levels in a single sample injection. DURAG GROUP also provides H2-ready combustion control and safety solutions including customized burners, igniters, flame scanners supporting up to 100% hydrogen fuel mixtures, and video/thermography monitoring systems for safe, reliable operation with complex and variable fuel mixtures.
