Crowcon’s BESafe offers fast, accurate detection of hydrogen (H2), carbon monoxide (CO), and methane (CH4). Its dual-channel capability enables simultaneous monitoring of two gases and allows flexible configuration to suit different applications.

Specifically developed for the demands of battery backup and energy storage systems, BESafe features remote smart sensors that simplify installation and require minimal maintenance throughout their lifecycle.

Dual Channel Gas Detector for Battery Energy Storage

Detecting hydrogen, carbon monoxide and methane released during thermal runaway, enabling fast, reliable safety response.

Dual Channel Gas Detection

Supports two gas sensors, allowing flexible configurations based on application needs. Sensors can be placed remotely to monitor hard-to-reach areas or where space is constrained.

High-Performance Swappable Smart Sensors

Easily swap out pre-calibrated sensor trays without manufacturer intervention, reducing downtime and maintenance costs. Supports remote, non-intrusive testing to verify performance without interrupting operations. The sensor life indicator monitors service life and signals end-of-life status.

Multiple Signal Output

Analogue and relay outputs integrate easily with existing control systems and support multi-level audio-visual alarms. Additionally, RS-485 communication with Modbus RTU enables remote monitoring and data transmission.

User-Friendly Interface

High-definition OLED display clearly shows gas readings and alarms in any lighting conditions. At the same time, simple button controls make setup and adjustments quick and intuitive.

Compact and Flexible Structural Design

Compact design fits into limited spaces such as energy storage cabinets. The IP65-rated housing ensures reliable performance in harsh environments.

On-Site, Built-In Alarm Functions

High-decibel audible alarm and bright status indicators instantly alert users to abnormal status and provide at-a-glance visibility of operational state. Additionally, relay output can trigger external alarms or ventilation fans.
