Gas safety system for use with hydrogen,
This system is suitable for use with either tube furnaces using work tube end seals or chamber furnaces using A105 retorts.
Housed in its own cabinet, the system is required where hydrogen gas is used.
It provides greater safety and convenience in control of atmospheres
containing more than 5% hydrogen and incorporates a nitrogen purge gas.
A monitored burn-off pilot flame ensures exit gases are fully burned.
This system monitors the gas pressure, the burn-off flame and the furnace temperature.
Failure of any of these results in a safety nitrogen purge.
Systems with mass flow control are also available.
it is not possible to work below 750°C with H2
