High Pressure CO₂ Gas

High Pressure CO₂ Gas — engineered supply for demanding pressures

Engineers who require High Pressure CO₂ Gas often work above the critical point of 31 °C and 74 bar, where carbon dioxide behaves as a dense solvent.
REAL GAZ delivers the gas with documentation suited to this duty and advises on equipment rated for the pressure.

Systems should comply with the Pressure Equipment Directive, ISO 9809 for cylinders and EN ISO 2503 for pressure regulators.

Above its critical point carbon dioxide has liquid-like density and gas-like diffusivity, a combination that makes it valuable as a solvent. Process developers often start at laboratory scale with a few cylinders and later scale to pilot plants. REAL GAZ supports that journey by supplying consistent gas at every stage and by providing documentation for the safety review of each step. Written operating procedures and a pre-start checklist for each rig are available on request from our technical team.

🏭 Where High Pressure CO₂ Is Used

⚙️ Supercritical extraction — decaffeination, hops and essential oil extraction use CO₂ at several hundred bar;
🔬 Enhanced oil recovery tests — laboratories simulate CO₂ injection in core samples;
🏥 Material testing — pressure rigs verify seals, hoses and valves with CO₂ service;
🚀 Polymer foaming — dense CO₂ acts as a physical blowing agent for microcellular materials.

💡 Why Choose REAL GAZ

✅ Rated components — regulators, hoses and fittings are specified for the maximum pressure;
🧪 Low impurity feed — clean CO₂ avoids contamination of extracts and polymers;
🎯 Engineering support — staff assist with system design reviews and safety checks;
🔒 Safe venting — guidance for relief lines and enclosed spaces is provided;
📄 Certificate of Analysis (CoA) — supplied with every order.

🔬 Quality Control & Safety

pressure test records for cylinders and assemblies;
analysis of moisture to prevent hydrate and ice formation;
inspection of seals and burst devices;
checks on cylinder temperature limits.

Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.

📦 Working Safely Above Critical Pressure

Expand CO₂ slowly across pressure reducers, because rapid expansion cools the gas strongly and can freeze components;
Protect rigs with burst discs sized for the maximum allowable working pressure, and vent to a safe outdoor location;
Use materials compatible with dense CO₂, as some elastomers swell or fail after repeated pressure cycles;
Inspect and pressure-test lines and fittings at regular intervals, recording results in a maintenance log.
