QT-COMP Integrated Gas Control System
QT-COMP is a compact, tubeless gas control system for OEMs and system integrators. Flow and pressure modules can be combined with valves, filters, and mixing chambers on a modular manifold. Configurations with 3 to 9 channels are available. Factory assembly and testing simplify commissioning, while top-access modules support maintenance in space-constrained equipment.

Measurement conditions & notes
- QT-COMP employs tubeless surface-mount technology, integrating all functional modules on a unified manifold, significantly reducing leak risks and installation space compared to traditional tubing connections.
- Combine mass flow meters/controllers, pressure sensors/controllers, filters, mixing chambers, shut-off valves, and 3-way valves as needed.
- Bottom connection design allows easy top-access maintenance and module replacement without disconnecting bottom plumbing.
- Fully factory tested and calibrated for "plug-and-play" installation, dramatically reducing on-site commissioning time and cost.
- Supports multiple industrial communication protocols for seamless integration with PLC/DCS/DCIM supervisory systems.
- Face seal fittings, compression fittings or flanges can be configured to meet various industry requirements.
- Typical applications: semiconductor CVD/etching, analytical instrument carrier gas control, bioreactor gas mixing, chemical process control, vacuum/plasma/sputter coating, combustion control, catalyst evaluation, etc.
