Hydrogen Exhaust Fan Kit
HEF-KIT
The BHS Hydrogen Exhaust Fan Kit (HEF-KIT) monitors hydrogen gas levels, activating operating alarms and ventilation fans when necessary to exhaust gases. The HEF-KIT is intended for use in battery charging rooms and other areas where hydrogen gas may be present.
- Continuous monitoring of hydrogen gas levels
- Reliable, highly sensitive, highly stable solid state sensor
- Forced ventilation
- Positive airflow shutoff
- Louvered dampers on exterior of fan prevent domestic air from escaping the room while fan is not in operation
- Remote firefighter’s shutdown capability (recommended per NEC 501)
- Improve battery room air quality by exhausting gases produced during battery charge
- Reduce costs with controlled fan operation and prevent unnecessary escape of climate-controlled air
- A HEF-KIT aids in compliance with the following standards:
NEC 480.9 Ventilation of Battery Rooms, NEC 501.125. (B), 501.105 (1-3), NFPA 2 Hydrogen Technology Code
- HEF-KIT
