Evikon E2630-HFC is a detector designed to monitor the concentration of R454C refrigerant in air. The device uses a semiconductor sensor that provides accurate real-time measurements. Thanks to its reliable performance and easy installation, it is an ideal choice for commercial and industrial applications where refrigerant leak monitoring is essential.

The device is housed in a wall-mounted enclosure with IP65 protection, ensuring resistance to dust and water. The E2630-HFC detector is equipped with a visual and audible alarm that provides timely warning when the R454C concentration rises. In addition, it offers two SPDT relay outputs for easy integration with ventilation control systems or alarms, ensuring a comprehensive safety solution.

Typical applications:

The E2630-HFC detector is intended for monitoring R454C refrigerant leaks in environments such as plant rooms, air conditioning and refrigeration equipment, refrigerant storage areas, or other installations where refrigerant concentration monitoring is required. The device provides early leak detection, helping to minimise the risks associated with refrigerant leakage and protect both the environment and equipment.

R454C:

R454C is a next-generation synthetic refrigerant used in air conditioning and refrigeration systems as a replacement for refrigerants with a higher global warming potential (GWP), such as R404A. It is a blend of hydrofluoroolefin (HFO) and hydrofluorocarbon (HFC), ensuring efficient heat transfer with a significantly lower climate impact. Unlike non-flammable refrigerants, R454C is classified as mildly flammable (ASHRAE A2L class), and therefore monitoring for leaks is crucial not only from an environmental perspective, but also for operational safety.

Calibration certificate

Every Evikon gas detector package includes a factory-issued calibration certificate. The calibration certificate is in English. Gas concentration measurement is affected by operating temperature and humidity, therefore the detector is calibrated during production with enhanced safety in mind.
