Typical applications

The E2630-HFC detector is designed to monitor R407c 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 leak detection, helping to minimise the risks associated with refrigerant leakage and protect both the environment and the equipment.

1,3,3,3-tetrafluoropropene (R407c)

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, an R407c leak can contribute to greenhouse gas emissions and affect air quality. Monitoring R407c leaks is essential for ensuring equipment safety and protecting the environment.

Smart communication – ideal for fire alarm systems

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:

• 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.

Wi-Fi calibration from any smart device

Compared to the standard version, the E2639-WF has an integrated Wi-Fi 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 section of the settings.
