Typical applications

The E2639-VOC(C2H6O)-LEL detector is intended for monitoring ethanol in environments such as breweries, wineries, distilleries, pharmaceutical production facilities, disinfection operations, laboratories, and storage areas for alcoholic products or cleaning agents, as well as other enclosed spaces where vapours of this volatile and flammable solvent may accumulate.

Ethanol (C2H6O)

Ethanol is a volatile and flammable liquid whose vapours spread easily through the air and can build up to dangerous concentrations in enclosed spaces. Although it has a characteristic alcoholic odour, this cannot be fully relied upon for leak detection, as the sense of smell becomes dulled during prolonged exposure and ceases to perceive it reliably. Exposure to higher concentrations of ethanol vapours may cause headaches, dizziness, nausea, or respiratory irritation, and prolonged or intense exposure may result in damage to the liver and central nervous system. Due to its flammability, it also presents a significant fire or explosion risk.

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.

WiFi calibration from any smart device

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 each user works only within their own section of the settings.
