# Hydrogen Gas Safety System

## HYDROGEN GAS SAFETY SYSTEM 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 control cabinet, off-the-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 allow hydrogen and nitrogen flow to be blended to suit the process. A monitored electrically heated gas ignitor ensures the hydrogen is fully consumed.

#### STANDARD FEATURES![](https://opti-tech.ca/wp-content/uploads/2023/02/llimagecaptioncontrolboxandburnerassembly-300x200.webp)

- Over-pressure protection for the work tube or retort
- Excess flow (rupture) protection
- Purge timer
- Independent safety purge
- Supply gas monitoring
- Furnace temperature monitoring

## HYDROGEN GAS SAFETY SYSTEM 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 safely handling 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.*

STANDARD FEATURES

- Full hydrogen operation for tube furnaces always in combination with a minimum of one inert gas
- Hydrogen from room temperature (RT) up to the maximum temperature
- Safety-related SPS with touch panel control
- Purging tank (N2)
- Tube materials up to 1100 °C: Quartz
- Tube materials up to 1800 °C: RCA
- Water cooled flanges

#### OPTIONS

*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 an emergency, this tank provides enough inert gas to purge the whole furnace multiple times to ensure that no dangerous gas remains in the furnace.*

- - Sample thermocouple
  - Fine vacuum pump
  - High vacuum pump
  - Second inert gas
  - Cascade control
