Overview

Lead-acid batteries release hydrogen gas during the charging process. Proper ventilation in the battery room is necessary to ensure potentially dangerous gases are diffused. The BHS Battery Room Ventilation System (BRVS) is designed to detect hydrogen gas at low levels and dissipate the gas to prevent accumulation.

Functionality

The Battery Room Ventilation System (BRVS) incorporates the Ventilation Stands, Hydrogen Gas Detector (HGD), Hydrogen Exhaust Fan (HEF), and exhaust duct work into one complete system.

The HGD monitors hydrogen gas levels and provides warning of increasing levels before they become dangerous. The HGD controls the HEF; therefore, the powered exhaust fans will run when the concentration of hydrogen gas has reached 1% or greater. This feature will help a facility save money by both reducing the run time of the fans and by preventing the unnecessary escape of climate-controlled air.

The Ventilation Stands and connected exhaust duct network are designed to capture hydrogen gas with or without forced ventilation. As gas exits the batteries, it flows through a network of ducts to safely exit the building with the aid of the HEF.

When the BRVS is used in conjunction with the Electrical Distribution System (EDS), the optional Charger Shutdown disables the chargers when an excessive amount of hydrogen (more than 2%) is detected in the area. By disabling the chargers, the production of hydrogen gas is stopped.
