System bezpiecznej pracy z wodorem

A laboratory gas safety system is required for safe operation when using hydrogen gas in Carbolite Gero tube furnaces or metallic chamber retorts. Two different sytems are available, one for hydrogen use from 750 °C to Tmax and one for hydrogen use from room temperature to Tmax.

System bezpiecznej pracy z wodorem 1 750 °C to Maximum Temperature

This system is suitable for use with either tube furnaces using a suitable work tube package or chamber furnaces using an A105 retort up to a maximum internal volume of 50 litres.

It is supplied with its own control cabinet, off gas burner and flexible pipes with fittings to connect directly to a gas atmosphere work tube package or chamber A105 retort.

The system automatically purges the work tube or chamber with nitrogen, ensures hydrogen is only introduced to the furnace above a safety temperature of 750 °C, and provides an end purge of nitrogen. A nitrogen purge also occurs in the event of unplanned shutdowns.

Two adjustable flow meters provide the facility for hydrogen and nitrogen flows to be blended to suit the process. A monitored electrically heated gas ignitor ensures the hydrogen is fully consumed.

System bezpiecznej pracy z wodorem 2 Room temperature to maximum temperature

This hydrogen tube furnace system is based on the F-range and HTRH-range. It is designed to meet all required regulations for the safe handling of hydrogen gas.

Note: The system is only suited for clean processes. No outgassing of the samples must occur.

HTRH 16/100/600: Hydrogen tube furnace with a heated length of 600 mm up to 1600 °C. Operation under pure hydrogen is possible. All necessary safety provisions are implemented.

HTRH 16/100/600: Hydrogen tube furnace with a heated length of 600 mm up to 1600 °C. Operation under pure hydrogen is possible. All necessary safety provisions are implemented.

A touch panel interface is used for automated operation. All valves, temperatures, gas flows, etc. can be switched on and off manually or automatically by a predetermined program.

Purging tank (N 2 )

The purging tank is filled with inert nitrogen at a pressure of 8 bar. The purging tank is a required safety option when working with pure hydrogen or other dangerous gases. In case of an emergency this tank provides enough inert gas for purging the whole furnace multiple times to ensure that no dangerous gas remains in the furnace.
