Prevent-iON®
Prevent-iON is the only listed, open & modular sensor platform designed to protect & detect energy storage systems (ESS).
Suited for lithium-ion (li-ion), lead acid or other battery chemistries. Utility, commercial or industrial ESS.
Suited for lithium-ion (li-ion), lead acid or other battery chemistries. Utility, commercial or industrial ESS.
Prevent-iON detects all 3 critical phases:
Stage 1 - Abuse Phase: monitoring the environment of the ESS.
Stage 2 - Off-Gas Phase: detecting the electrolyte gases coming from li-ion batteries right before thermal runaway.
Stage 3 - Thermal Runaway Phase: detecting the flammable gases from thermal runaway (H2, CH4, CO, ...).

Stage 3 - thermal runaway detection
Calibration free H2, flammable and VOC gas sensors
Introducing R-GAS-FLAMMABLE —the world’s first calibration-free flammable gas sensor designed specifically for battery energy storage systems (ESS). Boasting an exceptional lifespan of over 10 years, this sensor detects more than ten different flammable gases across the entire operational range of ESS—from -30°C to +75°C and 0% to 100% relative humidity (non-condensing).
With twice the lifespan of traditional sensors, the R-GAS-FLAMMABLE delivers significant CAPEX savings. Its calibration-free design further reduces OPEX, minimizing operational costs associated with gas monitoring.
Choose R-GAS-FLAMMABLE for a calibration free, cost-effective solution in flammable gas detection.

Stage 2 - off-gas detection
Listed electrolyte vapor (VOC) gas sensor platform
Introducing GAS-VOC—the calibration-free VOC gas sensor. A UL61010 recognized sensor that has been designed for Stage 2 off-gas (electrolyte vapor) detection in rack based battery energy storage systems (ESS). By detecting VOC, this sensor ensures safety and compliance for your commercial & industrial ESS installations with NFPA 855 requirements.
With pricing up to 60% lower than similar solutions from competitors, GAS-VOC offers significant CAPEX savings, making it a cost-effective choice for your gas detection needs.
