European engineering heritage and historic milestones of Ceodeux

Founded in 1922 in Lintgen, Grand Duchy of Luxembourg by engineer Auguste Theodore Schmitz, Ceodeux evolved from a regional carbon dioxide manufacturer into a premier world leader in precision gas engineering.

In 1926 the firm engineered its first proprietary valve for carbon dioxide cylinders, establishing a long-standing specialization in high-pressure shutoff valves.

Subsequently the product portfolio broadened to incorporate fire extinguisher valves, medical regulators, and ultra-high-purity gas equipment.

Today the enterprise forms the technological core of the international Rotarex Group, uniting nine business divisions and nearly two thousand engineering professionals across five continents.

High-pressure cylinder valve design and gas purity protection via RPV units

Industrial cylinder valves by Ceodeux are engineered for dependable long-term operation under working pressures up to 300 to 450 bar handling oxygen, argon, helium, nitrogen, and carbon dioxide.

Robust forged valve bodies machined from special brass and high-strength alloys provide superior mechanical durability against repeated pressure filling cycles.

A pivotal engineering element is the integrated residual pressure valve (RPV) featuring a non-return shutoff mechanism.

This unit maintains a positive pressure of approximately two to three bar inside depleted cylinders, shielding internal volumes from atmospheric moisture and external contamination while eliminating cylinder corrosion.

Precision flow regulation in gas headers and automated switchover panels

Consistent pressure delivery across analytical laboratories and industrial plant pipelines is secured by Ceodeux single-stage and dual-stage pressure regulators.

The implementation of corrugated Hastelloy metal diaphragms guarantees instantaneous responsiveness to inlet pressure fluctuations and eliminates seat deformation under pneumatic shocks.

Automated gas switchover manifold panels engineered by Ceodeux deliver uninterrupted gas feeding from dual cylinder banks.

When cylinder pressure in the primary line drops, the system seamlessly transfers feed to the reserve bank without pressure drops, transmitting telemetry alerts to plant supervisory control consoles.

Ultra-high purity standards of Ceodeux Puretec for semiconductor processing

Manufacturing semiconductor integrated circuits, photovoltaic cells, and microelectronics demands process gases with purity ratings reaching 99.99999 percent and complete freedom from particulates.

The Ceodeux Puretec series is engineered expressly for cleanroom facilities and semiconductor fabs requiring extreme flow channel cleanliness.

Internal fluid contact surfaces undergo electropolishing to Ra finishes below 0.1 microns.

The application of vacuum induction melted 316L VIM-VAR stainless steel and springless diaphragm mechanisms eliminates dead zones and fluid entrapment, ensuring verified helium leak integrity surpassing 1x10-9 mbar l/s.

Specialized discharge valves and actuation hardware for Firetec suppression systems

Automated gas extinguishing systems utilizing carbon dioxide, clean agents, and Novec 1230 inhibitors place strict demands on discharge speed and valve reliability.

Rotarex Firetec release valves incorporate differential piston mechanisms capable of containing agent pressures up to two hundred bar across years of continuous standby readiness.

Upon receiving an electrical, pneumatic, or manual actuation signal, the release head triggers within fractions of a second, delivering maximum extinguishing discharge rates into the protected compartment.

The units incorporate integrated piston position switches, pressure monitors, and safety pressure relief assemblies.

Meditec medical regulator valves and hydrogen fuel infrastructure equipment

The Meditec division manufactures integrated VIPR medical valves combining a shutoff valve, two-stage pressure reducer, oxygen flow selector, and residual pressure device within a single compact body.

This integrated architecture elevates emergency crew mobility while eliminating adjustment errors during therapeutic oxygen administration.

Within the clean mobility sector, Ceodeux manufactures heavy-duty cylinder valves and fueling receptacles for compressed hydrogen applications operating at pressures up to 700 bar.

Equipment is fitted with thermally activated pressure relief devices (PRD), providing controlled hydrogen discharge during extreme thermal hazard events.
