Measurement conditions & notes
- QT-ECO is the economical version of QT-COMP, maintaining compact integration and tubeless design advantages while optimizing cost structure, making it ideal for high-volume OEM applications.
- Compact construction effectively saves installation space, suitable for space-constrained equipment integration.
- Tubeless integrated design reduces fitting count, significantly lowering potential leak points and improving system reliability.
- Modular construction allows individual module replacement, convenient maintenance and reduced downtime.
- Factory pre-assembled, pre-tested and pre-calibrated for "plug-and-play" operation, reducing customer on-site testing and commissioning work.
- Manifold material available in aluminum (cost-effective) or stainless steel (corrosion-resistant), adapting to different media and environmental requirements.
- Custom configurations available: combine flow, pressure, filtration, valves and other functional modules per specific application requirements.
- Typical applications: process industry gas control, medical equipment gas delivery, analytical instrument gas circuits, bioreactors, food & beverage processing, semiconductor electronics manufacturing, welding shield gas mixing, laboratory gas systems, etc.
- Due to the wide variety of custom solutions, we recommend contacting GASKITO technical team to discuss your specific application requirements for an optimal configuration.
