Gas detector AVANSA 100M + solenoid valve G1" DN25

Product detailed description

Gas detectors are essential components in gas distribution systems, particularly in residential, commercial and industrial settings where gas leaks can pose serious safety risks. Installers and system designers commonly integrate these devices into gas supply lines to ensure rapid response to potential leaks. The AVANSA 100M gas detector is typically mounted in areas where gas accumulation is likely, such as boiler rooms, kitchens, or industrial gas storage areas. It works in conjunction with a solenoid valve to automatically shut off the gas supply when a leak is detected. The system is designed for environments with temperatures ranging from -15°C to 50°C and humidity up to 97% RH. The detector is suitable for both methane and LPG and is powered by standard 220V AC supply.

The technical parameters of the AVANSA 100M gas detector are critical for proper system sizing and integration. A sensitivity of 10% L.E.L. ensures early detection of flammable gas accumulation before it reaches dangerous levels. The response time of less than 30 seconds and a closing time of less than one second are essential for rapid system shutdown. The solenoid valve must be compatible with the gas type and system pressure, and the DN25/G1 inch thread ensures secure mechanical connection. The 12V DC solenoid control voltage must be matched with the control system’s output.

Installation and connection

To install the AVANSA 100M gas detector, the unit should be mounted in a location with good air circulation and visibility for inspection. The solenoid valve is connected to the main gas line using DN25/G1 inch threaded connections. Ensure the gas line is depressurised before fitting the valve and that the threads are sealed with appropriate thread tape or sealant. The detector must be wired to a 220V AC power supply, and the solenoid control circuit must be connected to a 12V DC source. The polarity of the solenoid circuit must be correct: white wire is positive, black wire is negative. A common mistake during installation is incorrect polarity, which can prevent the solenoid from functioning. Always verify the system’s operation after installation by testing the alarm and solenoid response.

Compatibility and accessories

This gas detector is compatible with systems using methane and LPG. It requires a 220V AC power supply and a 12V DC control source for the solenoid valve. No additional accessories are required for standard installation. The solenoid valve is pre-integrated into the unit, so no separate valve is needed. The unit is designed for use with standard gas piping systems and does not require special tools for installation.

Technical background for designers

The AVANSA 100M gas detector operates by detecting the presence of flammable gases at a concentration of 10% of the lower explosive limit (L.E.L.). The sensor technology is not specified, but the response time of less than 30 seconds indicates a fast-acting system. The solenoid valve is made of brass alloy with a nickel coating, which provides resistance to corrosion and wear. The sealing material is NBR/EKM rubber, which is suitable for gas applications. The system is integrated into the gas line and connected to a control circuit that triggers the solenoid valve when a leak is detected. The service life and efficiency of the unit depend on the environmental conditions, particularly temperature and humidity. Exposure to high humidity or extreme temperatures can affect sensor performance and solenoid operation.

Service and operation

Routine maintenance for the AVANSA 100M gas detector includes visual inspection of the unit and testing of the alarm and solenoid response. The system should be checked for proper operation at regular intervals, particularly after any system modifications or in the event of a false alarm. The solenoid valve should be tested manually to ensure it opens and closes correctly. No specific service intervals are provided in the technical data, but it is recommended to follow the manufacturer’s guidelines for periodic testing and inspection.

Frequently asked questions

Can the AVANSA 100M be connected to a 12V DC control system?
Yes, the solenoid valve can be connected to a 12V DC control system. The polarity must be correct: white wire is positive, black wire is negative.

Is the gas detector suitable for both methane and LPG?
Yes, the AVANSA 100M is designed to detect both methane and LPG. The sensor is calibrated for these gases and will respond to leaks of either type.

What is the maximum gas pressure the solenoid valve can handle?
The solenoid valve can handle a maximum pressure of 500 mBar. It can also withstand a pressure test of 1 bar for 20 minutes without failure.

Can the solenoid valve be opened manually?
Yes, the solenoid valve can be opened manually. This is useful for testing or in situations where the automatic control system is not functioning.
