QT-COMP Tubeless Compact Solution
QT-COMP tubeless compact solution is designed for OEMs and system integrators seeking maximum space efficiency. One or more mass flow/pressure sensor modules can be combined with control valves, shut-off valves, mixing chambers, filters, or other functional modules on a compact, lightweight yet rugged modular manifold rail. The tubeless design significantly reduces potential leak points, while bottom connections facilitate top/bottom mounting. Supports 3~9 channel flexible configuration. Factory assembled and tested for true "plug-and-play" operation, minimizing on-site commissioning time. Widely used in semiconductor, analytical instruments, biotechnology, chemical processing and other fields.
