Serial Gas Mixers – beyond standards
LT GASETECHNIK manufactures and supplies standardized serial gas mixers for flammable or non-flammable, corrosive or toxic gases, including associated technical control and analysis technology.
LT Serial Gas Mixer are available for
- 2 or 3 gases
- Performance range 15-1000 Nm³/h
- Inlet pressure 12-25 barg
- Output pressure 2-9 barg
- Gas mixture repeatability ± 0.5 Vol%
- With or without buffer vessel
LT GASETECHNIK provides individually planned Serial Gas Mixers and gas process plants for control system of pressure and/or flow or as gas mixing system. We design and manufacture Serial Gas Mixers for industrial gases applications with flammable or non-flammable, corrosive or toxic industrial gases, including associated control and analysis technology.

2. Typical fields of application for Serial Gas Mixers:
- Shield gas for the welding technology (e.g. Ar/CO2)
- Protective gas for the food industry (e.g. N2/CO2)
- Reaction gas for forging technology (e.g. Ar/O2/H2)
- Forming gas for steel- and rolling mills (e.g. N2/H2 and N2/H2/H2O)
- Forming gas (HNx) for the glass production (e.g. N2/H2)

4. Features
Our Serial Gas Mixers convince through:
Design
- High accuracy and repeatability of the gas mixture quality ± 0.5%
- Reliability
- Integrated compensation of significant inlet pressure differences (≥ 3 bar), because in every gas inlet line one LTD 1 dome loaded pressure regulator homogenizes the gas pressures.
- Design according to customer requirements
Safety
- Quality fittings and gas pipes
- Cryogenic metallic materials (fault protection)
- Proven interlocking and security concept
Technical features
- Customized metering (accuracy)
- High-quality, customized and easy-to-read flow meter
- Bypass: Precise analysis independent from the buffered gas mixture
- Blow-off pipe: Set up even without a connected consumer
- Gas filters in the gas supply lines
- Extremely low pressure loss
- Robust, designed for continuous use – more than 20 years of operation are usual
