Typical applications

The E2639-HFC detector is designed for monitoring R410a refrigerant leaks in environments such as plant rooms, air-conditioning and refrigeration equipment, refrigerant storage areas, or other installations where refrigerant concentrations must be monitored. The device provides early leak detection, helping to minimise the risks associated with refrigerant leakage while protecting both the environment and the equipment.

Difluoromethane and pentafluoroethane (R-410A)

R410a is a synthetic refrigerant widely used in air-conditioning and refrigeration systems. It is a colourless blend of two hydrofluorocarbon gases that provides efficient heat transfer. Although it is non-flammable, leakage of R410a can contribute to greenhouse gas emissions and affect air quality. Monitoring R410a leaks is essential for ensuring equipment safety and compliance with environmental standards.

Smart communication – ideal for fire alarm systems

The E2639 detector combines the advantages of an autonomous safety device and an intelligent communication node. It is designed for seamless integration with fire alarm systems (EPS) and offers a wide range of outputs for comprehensive control:

• Autonomy: 3× volt-free SPDT relays for direct control of equipment or safe system shutdown.
• Connectivity: Dual RS485 Modbus RTU interface for real-time digital export of measured data to a higher-level system (BMS).
• Control: 2× 4–20 mA analogue outputs intended for precise control of the ventilation frequency inverter.

WiFi calibration from any smart device

Compared to the standard version, the E2639-WF has an integrated WiFi module that turns calibration and configuration into a matter of minutes – with no tools and no need to remove the cover. The access point is activated using a magnetic key, and the configuration interface opens in the browser of your phone or tablet, with no need to download any app. The interface is password-protected with separate access levels for end users and integrators, so each user works only within their designated section of the settings.
