Crowcon BESafe Dual Channel Gas Detector

Crowcon BESafe Dual Channel Gas DetectorThe Crowcon BESafe™ Dual Channel Gas Detector is a high-performance, fixed gas detection solution for battery energy storage systems (BESS) and critical backup infrastructure. With the ability to monitor two gases simultaneously – hydrogen (H₂), carbon monoxide (CO) or methane (CH₄), BESafe offers early warning against thermal runaway events, battery off-gassing, and fire risks. Its compact form factor fits neatly into confined spaces such as energy storage enclosures, inverter rooms, or UPS cabinets, while rugged IP65-rated construction ensures reliable operation in harsh environments.
Equipped with modular, smart sensors that are pre-calibrated and swappable on-site, BESafe minimises maintenance downtime and eliminates manufacturer intervention. The integrated sensor life indicator and non-intrusive testing capabilities deliver consistent performance with minimal disruption to operations. Visual and audible alarms, including an 85dB sounder and multi-color LED indicators—provide immediate awareness of hazardous gas levels. In addition, multiple signal output options (including 4–20mA, RS-485 Modbus RTU, and SPDT relays) allow seamless integration into existing building management, SCADA, or safety systems.
With its OLED display for precise gas readings in all lighting conditions and built-in support for automatic control of external devices like fans or alarms, BESafe enhances safety and compliance in high-risk battery storage environments. Ideal for utility-scale BESS, EV charging infrastructure, data centres, and industrial hydrogen facilities. BESafe is the frontline technology for detecting critical gases associated with lithium-ion battery degradation and thermal failure.
