Evikon E2639-HFC(R407c) is a detector designed for monitoring high concentrations of R407c refrigerant 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 an RS485 Modbus RTU digital interface, complemented by two 4–20 mA analogue outputs. In addition, the device includes four LEDs and an audible alarm to immediately alert operators when the set limit is exceeded directly at the installation site – without the need to monitor a remote control system.
The E2630-HFC detector is intended for monitoring R407c refrigerant leaks in environments such as plant rooms, air-conditioning and refrigeration equipment, refrigerant storage areas, or other installations where refrigerant concentrations need to be monitored. The device is used for early leak detection, helping to minimise the risks associated with refrigerant leakage and protect both the environment and equipment.
R407c is a synthetic refrigerant commonly used in air-conditioning and refrigeration systems. It is a blend of three hydrofluorocarbon gases that provide efficient heat transfer. Although it is non-flammable, leakage of R407c can contribute to greenhouse gas emissions and affect air quality. Monitoring R407c leaks is essential for ensuring equipment safety and protecting the environment.
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:
The E2639 is equipped with three M20 cable glands and a dual terminal block for Modbus RTU. The duplicated Modbus RTU terminals simplify and speed up bus wiring for connection to a higher-level system. No more inserting two conductors into a single terminal. Thanks to the M20 cable glands, all required outputs can be connected conveniently.
Factory settings:
Each detector package includes the original manufacturer's calibration certificate in English, confirming the accuracy and correctness of measurement at the time of leaving the factory.
