The Merlin GDPX+ Gas Pressure Proving and Gas Detection System is a premium gas safety controller engineered for use in boiler rooms, mechanical plant areas, car parks, and industrial facilities. This advanced system combines gas pressure proving with 4-zone gas detection, offering complete gas safety assurance and regulatory compliance.
The pressure proving functionality detects leaks or pressure drops before allowing gas to flow, using a solenoid valve and transducer for precise measurement. The unit continuously monitors gas pressure to ensure stable flame conditions and safe operation.
Designed for advanced integration, the Merlin GDPX+ includes fire alarm input and bypass, BMS compatibility via MODBUS, and support for emergency shut-off buttons. It accepts a wide range of sensors including Natural Gas, CO, LPG, Hydrogen, and Oxygen depletion detectors, with live zone status shown on a full-color TFT touchscreen for real-time diagnostics.
