Evikon E2639-HFC(R32) is a detector designed to monitor high concentrations of R32 refrigerant (difluoromethane) in the 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 by the RS485 Modbus RTU digital interface, complemented by two 4–20 mA analogue outputs. The version with a Wi-Fi module allows 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(R32) detector is designed to monitor R32 refrigerant leaks in environments such as plant rooms, air conditioning and heat pump systems, residential and commercial buildings, or other installations where refrigerant concentrations need to be monitored. The device provides early leak detection, helping to minimise risks associated with its flammability, protect the environment, and ensure compliance with current legislation.
R32 (difluoromethane) is a single-component HFC refrigerant intended for use in air conditioning units and heat pumps. It is classified as mildly flammable, which requires thorough monitoring of system tightness. Early leak detection is essential to ensure operational safety and compliance with the requirements of the EU F-Gas Regulation on fluorinated greenhouse gases.
The E2639 detector combines the benefits 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:
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 without removing the cover. The access point is activated using a magnetic key, and the configuration interface opens in the browser of a 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.
