0-2000 SCFH (0-53.6 Nm3/h) Flowrate
Continuous gas analysis of the gas mixture,
Surge tank design produces a constant gas mixture proportion from shutoff to full flow conditions
a NEMA 4 enclosure for protection from weather or tampering
The analysis has a heated cell chamber for functioning at outdoor temperatures
Application:
The Thermco gas mixer is designed to mix two non-flammable and non-corrosive gases. The gas mixer is normally used with a process where the supply gases are drawn from bulk sources and the mixture is produced on-site where it is supplied to the process by a pipeline. The system is designed for applications that require a very reliable production for mixed gas on a continuous basis.
Common applications include shield gas for welding, leak detection mixtures, cover gas for molten metals and lamp filling mixtures.
Because the gas mixer uses a surge tank design, this type of system is ideal for applications that require maintaining a precise proportion from full mixed gas flow down to zero flow.
Standard Ranges (Indoor and Outdoor Models):
0-30% CO2 in Argon
0-10% Oxygen in Argon
0-50% Helium in Argon
0-50% Helium in Nitrogen
0-50% CO2 in Nitrogen
Gas Mixing Accuracy:
±2% of full range over 60°F to 80°F (15°C to 27°C) temperature range
±4% of full range over 32°F to 104°F (0°C to 40°C) temperature range
±8% of full range of -10°F to 104°F (-23°C to 40°C) temperature range
Stated accuracy assumes that the input temperature of the gases are equal.
Gas mixer accuracies depend upon many variables, including frequency of analyzer zeroing and calibration, gas mixer maintenance, and environmental conditions around the gas mixer. These accuracies are presented as typical performance for these systems.
Temperature Range – Ambient and Process Gas:
Normal Mixed Gas Outlet Pressure Range:
10-50 PSIG (0.7-3.4 barg) for models 6105, 6205, 8105, 8205.
Gas Connections and Piping:
For models 6105, 6205, 8105, 8205, 1 inch female NPT pipe for major, minor, and mixed gas connections. For other models consult the factory. Piping is brass and copper material.
Surge Tank:
30 gallon for Models 6105, 8105; carbon steel, ASME coded, and CRN registered; pressure safety relief valve provided.
Solid-State Surge Tank Pressure Switch:
The gas mixer utilizes a solid-state pressure switch to control the surge tank pressure. A digital readout of the pressure is built into the switch. Both the sensing element and electrical switch are solid-state. An LED indicator shows when the surge tank is filling. Use of this pressure switch virtually eliminates the most common cause of gas mixer failure.
Power Requirements:
115 VAC, 50/60 Hz., 0.5 ampere. Acceptable voltage range 104-126 VAC.
