Battery Room Safety

Accurate Hydrogen Detection Keeps Battery Rooms Safe

As businesses increasingly depend on backup power and energy storage in data centers, utilities, telecommunications and energy storage systems, battery rooms becoming more important. This trend, will drive more and larger battery rooms and with evolving code and standards requirements, bring the issue of detection and safe ventilation of hydrogen to the forefront.

Lead acid and Ni-Cad batteries are commonly used in battery applications because they offer cost-effective power storage. But these batteries dissipate hydrogen that can reach flammable levels. To minimize the risk, the hydrogen needs to be controlled to a maximum concentration of 25% of the lower flammability limit (LFL) or 1% of total room volume.

Until now, hydrogen detection systems required frequent calibration and replacement based on the available technology which significantly increased the cost of the system and required frequent truck rolls. Facility managers want to be able to set it and forget it… now you can!

Problems for the Battery Industry:

  • • Sensors that are consumed
  • • Labor intensive with high maintenance costs
  • • Analog communications
  • • Unreliable based on bad maintenance practices

New and Improved H2scan technology has solved the problems for Battery Room Applications:

  • • Not to have to run fans continuously
  • • Long 10+ year life with a 10-year warranty– lasts over 10 years (in outdoor use and even longer for indoor use
  • • Auto-calibration (note: the unit still calibrates, but no action is necessary from the user)
  • • Digital / Modbus communications
  • • Set and Forget!
To avoid risk of explosion and to avoid the high cost of constant ventilation of battery rooms, H2scan’s HY-ALERTA™ family of hydrogen specific area monitors detect hydrogen in air and can trigger alarms or ventilation systems when hydrogen levels get too high.

The unique solid state, non-consumable sensor technology built into the HY-ALERTA sensors provides real-time continuous hydrogen monitoring with no cross-sensitivity to other gases in the environment, particularly other combustibles.

Hydrogen Sensing Products for Battery Room Safety

HY-ALERTA™ 5021 Solid-State Area Hydrogen Monitor

H2scan’s HY-ALERTA 5021 solid-state area hydrogen monitor is a reliable, hydrogen gas detector for real-time monitoring of battery rooms that avoids false positives from other gasses. The auto-calibrating technology allows data centers, utilities, telecommunications, and energy storage systems end users to deploy it maintenance-free, with no calibration or board replacements needed throughout the life of the unit.


HyView™ is an explosion-proof process meter display with the ability to consolidate data from multiple hydrogen sensors. HyView provides more value to the high-accuracy, low maintenance GRIDSCAN 5000 sensor for transformer reliability. Adding the ability to read hydrogen data locally allows the operator greater real-time access to important reliability and safety data, turning it into valuable information through which critical asset management and safety decisions can be made. One of the most advanced and feature-packed explosion-proof, loop-powered indicators on the market, HyView eliminates the need to run additional, costly power lines into a hazardous area.
