The Eagle Eye HGD-2000 Hydrogen Gas Detector allows the user to monitor hydrogen gas buildup in storage rooms and facilities that house batteries - including forklifts, golf carts, backup power supplies, and battery charging stations. Lead-acid batteries on charge emit hydrogen gas after reaching the 80% recharge point. When mixed with enough air, hydrogen becomes a highly flammable gas that can ignite easily with just a spark, destroying equipment and harming personnel. The lower explosive level (LEL) for hydrogen is 4.1% by volume. The dangers of hydrogen gas explosion are eliminated by using the HGD-2000 hydrogen (H2) gas detector.
Hydrogen is colorless and odorless, the lightest of all gases and thus rises. The HGD-2000 should be installed at the highest, draft-free location of the room where hydrogen gas would accumulate. The sensor of the HGD-2000 consists of a semiconductor whose electrical conductivity increases when hydrogen is absorbed on its surface. Conductivity, proportional to the gas concentration, is continuously measured by an electric circuit. The HGD-2000 is factory-calibrated and field-calibrations should not be performed.
Applications
- Utilities and Power Plants
- UPS Power Systems
- Fuel Cell Test Stations
- Nuclear Waste Reforming
- Hydrogen Refueling Stations
- Fire Department
- Battery Suppliers
- Battery Charging Rooms
- Motive Power
- Golf Cart
The HGD-2000 fixed hydrogen gas detector is easy-to-use and easy-to-install. Attach the HGD-2000 to the wall, ceiling, or optional junction box using the mounting holes at the top and bottom of the detector box. The detector has a terminal block for connection to single-phase AC power source and two internal relays. The relays can be used to switch a remote exhaust fan and/or alarm on and off. The detector should be kept on at all times, and the green LED will be lit. If the concentration of hydrogen gas in the air surrounding the sensor reaches 1% by volume, the yellow LED will light and the 1% internal relay will close. A four second delay prevents false activation. If the concentration reaches 2%, the red LED will flash, the internal 80 db warning alarm will sound, and the 2% internal relay will close.
Properly installed, the HGD-2000 is compliant with The National Electric Code (NEC) Section 480.9 (A) for ventilation of battery rooms. This is also the specified requirement for solar or wind generated power Battery Rooms. The hydrogen gas detector is also compliant with The National Fire Protection Association, NFPA 2 Hydrogen Technology Code, which is more stringent. The minimum system consists of an H2 Hydrogen Gas Detector, an H2 Battery Room Forced Ventilator with Positive Airflow Shut Off, a remote firefighter’s shutdown capability, a backflow damper, and a 2% monitored alarm. This unit complies with NEC 501.125. (B), 501.105 (1)-3 and is designed for use in Class 1 Div. 2 Group B hydrogen containing classified areas.
