Evikon E2639-HFC(R410a) is a detector designed for monitoring high concentrations of R410a refrigerant in ambient air. The device is equipped with a temperature-compensated sensor that ensures reliable detection and stable measurement, and it is housed in a wall-mounted enclosure with IP65 protection. The E2639 features three SPDT relays with a maximum load of 250 VAC 5 A. Two relays are used for so-called two-stage detection. The third relay indicates a sensor fault. Communication with higher-level systems is provided via the digital RS485 Modbus RTU interface, complemented by two 4–20 mA analogue outputs. The version with a Wi-Fi module enables wireless connection of a smartphone or tablet for configuration and calibration via a web interface – with no need to install an app. In addition, the device includes four LEDs and an audible alarm, which immediately alert operators to an exceeded set limit directly at the installation site – without the need to monitor a remote control system.
The E2639-HFC detector is intended for monitoring R410a refrigerant leaks in environments such as plant rooms, air-conditioning and refrigeration equipment, refrigerant stores, or other installations where refrigerant concentrations need to be monitored. The device is used for early detection of refrigerant leaks, helping to minimise the risks associated with leakage and protect both the environment and the equipment.
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, R410a leakage can contribute to greenhouse gas emissions and affect air quality. Monitoring R410a leaks is essential for ensuring equipment safety and compliance with environmental standards.
The E2639 detector combines the benefits of an autonomous safety element and an intelligent communication node. It is designed for seamless integration with fire alarm systems (FAS) and offers a wide range of outputs for comprehensive control:
Compared to the standard version, the E2639-WF has an integrated WiFi module that turns calibration and configuration into a matter of minutes – without tools and without removing 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 everyone works only within their own part of the settings.
Factory settings:
Each detector package includes the manufacturer's original calibration certificate in English, confirming the accuracy and correctness of measurement at the time of leaving the factory.
