A dual-channel fixed gas detector purpose-built for battery energy storage systems — simultaneously monitoring hydrogen, carbon monoxide, and methane released during thermal runaway events, with swappable smart sensors, OLED display, and relay output for external alarm or ventilation triggering.
The Crowcon BESafe is a fixed dual-channel gas detector specifically developed for battery backup and energy storage system (BESS) applications — an increasingly critical safety requirement as the Alberta energy sector integrates battery storage into oilfield power infrastructure, renewable energy projects, and remote facilities. During a thermal runaway event, lithium-ion battery systems release hydrogen, carbon monoxide, and methane — gases that can accumulate rapidly in enclosed energy storage cabinets and create both toxic and explosive hazards. BESafe detects all three with fast, accurate dual-channel simultaneous monitoring, allowing flexible sensor pairing to match the specific risk profile of each installation. Remote smart sensors can be positioned inside cabinets or in hard-to-reach spaces where the controller unit cannot be mounted, while the compact polycarbonate controller fits neatly into space-constrained installations. Swappable pre-calibrated sensor trays require no manufacturer intervention to replace, and built-in sensor life monitoring signals end-of-life before sensor failure. Dual 4-20mA outputs and RS-485 Modbus RTU integrate into existing control systems, while relay outputs can trigger external alarms or ventilation fans directly. With an operating temperature range of -40°C to +75°C and IP65 housing, BESafe is suited to both indoor and outdoor energy storage deployments across Alberta.
