Real-World OEM Gas & Pressure Control Applications
Leierda’s OEM gas and pressure modules are proven across analytical, industrial, and automation systems, delivering stable regulation and reliable monitoring in compact, long-life designs.
Gas Analysis Equipment Integration Module
Challenge:
An analytical equipment manufacturer faced unstable pressure and minor cross-contamination in its gas supply system due to standard single-stage regulators, affecting test repeatability. A compact, high-purity regulator module was needed for seamless OEM integration.
Solution:
Leierda supplied the dual-stage stainless-steel regulator, customized with 1/4-inch panel-mount fittings and quick connectors. PTFE sealing and polished, degreased flow paths ensured gas purity with a helium leak rate ≤ 1×10⁻⁷ mbar·L/s.
Result:
Baseline drift was reduced by 80%, and analytical repeatability improved significantly. The module was standardized in the customer’s OEM assembly for multiple gas analysis systems.
Automated Equipment Gas Pressure Control System
Challenge:
An OEM manufacturer required stable gas pressure regulation with signal feedback for automated machinery. The existing single-stage regulators were unstable under high-temperature, long-duty conditions and lacked digital monitoring capability.
Solution:
Leierda provided a dual-stage pressure regulation and monitoring solution, combining high-precision regulators with integrated pressure transmitters to deliver stable control and real-time feedback to the PLC system. All components were built with 316L stainless steel, ensuring long-term reliability and resistance to heat and corrosion.
Result:
System pressure remained stable within ±0.04 bar, and pressure-related alarms were significantly reduced. The OEM later standardized this modular gas control design across its next-generation automation platforms.
Oxygen Control Module for Medical and Laboratory Devices
Challenge:
A medical equipment manufacturer required oxygen-compatible pressure regulation meeting high-purity and cleanliness standards. The original system lacked degreasing treatment, leading to minor leakage and delayed adjustment response.
Solution:
Leierda supplied the dual-stage oxygen regulator, featuring a degreased stainless-steel body and PTFE sealing. Internal flow paths were finely polished and helium-tested to ≤ 1×10⁻⁷ mbar·L/s. Stainless-steel pressure gauges provided local pressure indication.
Result:
The system maintained 99.999 % oxygen purity with zero leakage or drift. The design passed medical gas safety certification and has since been deployed in multiple diagnostic and laboratory devices.
High-Pressure Hydrogen Control Module for Energy Systems
Challenge:
A customer developing high-pressure test benches required precise and safe pressure control modules capable of handling up to 20 MPa, while preventing startup surge and ensuring long-term stability.
Solution:
Leierda delivered the dual-stage high-pressure hydrogen regulator, featuring a reinforced diaphragm, short-stroke valve design, and integrated relief protection. Combined with pressure transmitters, the system offered real-time monitoring and overpressure alarms.
Result:
The system operated continuously for six months without pressure spikes or leakage. Output pressure remained within ± 0.02 bar, maintenance intervals were extended, and Leierda modules were standardized in subsequent OEM designs.
