Generator Safety Features
The Precision Hydrogen range have the following safety features to ensure safe and
reliable operation:
1. To avoid any build up of hydrogen from leaks inside the unit; the generator features
forced air ventilation. This ensures that a hydrogen / oxygen mixture cannot form
inside the generator.
2. On power-up the generator self checks for internal leaks and if required it will
shutdown at the end of the System Check informing the operator with a visual and
audible alarm.
3. The generator will detect any hydrogen leaks that occur within the generator, the
user’s application and gas lines. In the event of a major leak the generator will
automatically shut down within 20 minutes.
4. The hydrogen pressure inside the generator should only reach a maximum of 7.5 bar
(110psi) and this is controlled in two ways:
a. Gas pressure is monitored and controlled electronically by a pressure sensor
b. A mechanical pressure switch (Fail Safe) will electrically isolate the hydrogen cell
should the internal pressure reach 9 bar (130psi).
5. When the generator is in alarm status the following occurs:
a. The current to the cell is stopped so no hydrogen is generated therefore preventing
a hazardous situation.
b. The over pressure relief valve opens allowing the unit to depressurise.
c. An audible alarm sounds and a visual alarm, relevant to the fault condition, is
displayed. The generator can sense for internal and external leaks, excessive gas
demand and lack of water.
