Gas detector AVANSA 100M + solenoid valve G1/2" DN15

Product detailed description

The AVANSA 100M gas detector with solenoid valve is commonly installed in environments where gas leaks pose a significant risk, such as industrial facilities, residential heating systems, and commercial kitchens. Installers typically integrate this unit into gas supply lines to ensure rapid detection and automatic shut-off in case of a leak. The device is suitable for both indoor and outdoor use, provided ambient conditions remain within the operational temperature range of -15°C to 50°C and relative humidity below 97%. The compact design allows for flexible mounting near gas appliances or in utility rooms, ensuring proximity to potential leak points.

Its solenoid valve component provides an electromechanical shut-off mechanism that can be triggered manually or via the detector’s alarm signal. This integration supports both manual emergency response and automated safety protocols, making it ideal for applications requiring high levels of safety compliance. The solenoid valve is rated for a maximum working pressure of 500 mBar and features brass-nickel construction for durability in corrosive environments. The detector itself operates on a catalytic combustion principle, detecting flammable gases at 10% of their lower explosive limit (L.E.L.), ensuring early warning before dangerous concentrations are reached.

Technical parameters

Installation and connection

Installation should be carried out by a qualified professional following local safety regulations. The detector must be mounted in a location free from obstructions, ideally at a height of 1 to 2 meters above ground level for methane detection or lower for heavier gases like LPG. The solenoid valve is connected to the gas supply line using G1/2' DN15 threaded fittings. Ensure all connections are tight and sealed with appropriate thread sealant or PTFE tape.

Before commissioning, verify that the power supply is stable at 220V AC 50Hz and that the polarity of the 12V DC wiring is correct—white wire for positive, black wire for negative. Check the continuity of the solenoid coil and confirm that the valve closes fully when activated. A common mistake is incorrect orientation of the detector, which can lead to delayed or missed detection. Always perform a functional test after installation to confirm alarm activation and valve closure.

Compatibility and accessories

The AVANSA 100M is designed for use with standard gas supply lines and is compatible with most domestic and light industrial gas systems. It requires a dedicated 220V AC power supply and a 12V DC source for the solenoid valve. Additional components such as junction boxes, conduit, and sealing materials may be necessary depending on the installation environment and local regulations. No specific accessories are required for basic operation, but a test gas cylinder may be useful for calibration checks.

Technical background for designers

The detector operates on a catalytic combustion sensor, which reacts to the presence of flammable gases by measuring the heat generated during oxidation. The sensor is housed in a durable casing made of rubber NBR/EKM, chosen for its resistance to common gases and environmental factors. The solenoid valve is constructed from brass-nickel alloy, offering good corrosion resistance and mechanical strength. Integration into a larger system requires consideration of the control voltage and the need for a stable power supply to avoid false alarms or failures during operation.

System designers should account for the detector’s 220V AC requirement and the 12V DC input for the solenoid valve. The maximum pressure rating of 500 mBar ensures compatibility with standard gas distribution systems. Long-term performance is influenced by exposure to extreme temperatures or high humidity, which may affect sensor accuracy over time. Regular testing is recommended to maintain system reliability.

Service and operation

Maintenance involves periodic inspection of the sensor and solenoid valve for physical damage or blockages. The detector should be tested regularly using a certified test gas to ensure it triggers the alarm and activates the valve correctly. No scheduled service intervals are specified in the technical documentation, but it is advisable to follow local safety guidelines for routine checks. If the alarm sounds frequently without cause, investigate potential false triggers such as vapours from cleaning agents or solvent use.

During operation, the detector continuously monitors the air for gas concentrations. If a leak is detected, the alarm sounds above 90 dB at 1 meter distance, and the solenoid valve closes within one second. After a leak event, the system must be reset manually. In case of suspected malfunction, disconnect the power and inspect the wiring and sensor for signs of wear or contamination.

Frequently asked questions

Can the AVANSA 100M be used with both methane and LPG systems?
Yes, the detector is calibrated for both methane and liquefied petroleum gas (LPG) and can be integrated into systems using either fuel type.

Is the solenoid valve compatible with 12V DC control systems?
Yes, the solenoid valve is designed to operate with a 12V DC power supply, allowing it to be controlled by standard low-voltage systems.

What is the maximum pressure the solenoid valve can handle?
The solenoid valve is rated for a maximum working pressure of 500 mBar and has passed a 1 bar pressure test for 20 minutes.

Can the detector be opened manually?
No, the detector does not have a manual open function. The solenoid valve can be opened manually, but the detector itself cannot be manually triggered to open.
