GSL2Z-S Compact Two-Channel Gas Delivery System with PLC Touch Panel Control for Vacuum-Sealed Tube Furnaces
The GSL2Z-S is engineered to provide precise and reliable gas mixing and delivery for vacuum-sealed tube furnace processes requiring two distinct gases. It is particularly suited for applications where controlled gas flow and composition are critical, such as chemical vapor deposition or material synthesis under controlled atmospheres.
This compact system integrates two precision mass flow controllers (MFCs) that regulate gas flow rates independently, ensuring accurate mixing ratios. The device operates effectively within a temperature range of 5 to 45 ºC and can handle pressures up to 3×10⁶ Pa, making it suitable for demanding laboratory environments.
Key Features
- Two built-in precision mass flow controllers with flow ranges of 1–99 SCCM and 1–199 SCCM respectively.
- 6-inch color PLC touchscreen panel for intuitive control and parameter adjustment.
- Integrated stainless steel gas mixing tank (Φ80 x 120 mm) and internal 1/4″ O.D. stainless steel pipeline.
- Mechanical pressure gauge with measurement range from -0.1 to 0.15 MPa and 0.01 MPa per grid resolution.
- 316 stainless steel needle valves and Swagelok tube fittings for robust and leak-free connections.
- Power supply compatible with AC 110–240 V single-phase, 50/60 Hz, consuming 100 W total power.
- Optional oxygen sensor available for monitoring oxygen levels to prevent oxidation during CVD processes.
