Overview

Plant air in, 350 bar O2 out.

The Oxygen Gas Boosting System is a compact, skid-mounted unit engineered to elevate oxygen pressures up to 350 bar using only plant compressed air as the drive medium.

Driven by plant air at 3–7 bar (or an optional hybrid electric drive), the booster raises oxygen from a 20–120 bar inlet to a maximum outlet of 350 bar (about 5,000 psi) with no electrical components in the gas path — eliminating ignition risk and ensuring intrinsic safety for oxygen service. Three- to five-stage piston compression with stainless-steel intercoolers keeps gas temperatures below 80°C throughout the boost cycle.

All wetted parts, hoses, gauges and vessels are cleaned and certified to ASTM G-93, with an inline oxygen analyzer and moisture sensor maintaining purity above 99.5% O2 and dew point below −40°C after filtration — meeting medical and semiconductor-grade requirements. An integrated PLC/HMI with 7″ touchscreen provides recipe storage, event logging and SCADA/Modbus connectivity for remote operation.

No electricity in the gas path. No ignition risk.

A fully pneumatic design is approved for Zone 2 hazardous areas; an ATEX-rated electric variant is available where a hybrid drive is preferred. Automated post-shutdown purge and 210 bar safety-relief protection round out a system built for cylinder filling, emergency backup and continuous feed duty in medical, industrial and defence installations.

Introduction

The Oxygen Gas Boosting System is a compact, skid-mounted unit designed to elevate oxygen pressures up to 350 bar (≈5,000 psi) using only plant air (3–7 bar), eliminating electrical ignition risks and ensuring intrinsic safety for oxygen service. Its oxygen-clean construction (ASTM G-93), multi-stage compression and integrated control logic make it suitable for cylinder filling, rebreather top-off, emergency backup and continuous feed in critical medical, industrial and defence applications.

Key features

Multi-stage compression with intercooling: three- to five-stage piston arrangement with stainless-steel intercoolers to maintain gas integrity and manage temperatures below 80°C.
Variable drive-air control: optional proportional valve or hybrid electric drive for soft-start and optimized air consumption.
Purity & dew-point monitoring: inline oxygen analyzer (>99.5% purity) and moisture sensor (dew point <−40°C) for medical and semiconductor standards.
Oxygen-clean design: all wetted parts, hoses, gauges and vessels cleaned and certified to ASTM G-93; hydro-test-certified hoses and calibration certificates included.
Explosion-proof operation: fully pneumatic (or ATEX-rated electric) design approved for Zone 2 hazardous areas.
Integrated PLC/HMI interface: 7″ touchscreen with recipe storage, SCADA/Modbus connectivity, event logging and self-diagnostics.
Automated purge & relief: post-shutdown purge clears residual O2; safety-relief valves set at 210 bar protect against over-pressure.
Modular skid-mount construction: forklift pockets, lifting eyes, shock mounts and pre-piped skid for rapid deployment.

Principle of operation

Startup: drive-air signal or electric motor engages the booster at low stroke, ramping to full flow.
Compression: oxygen passes through staged pistons; intercoolers remove heat to protect gas quality.
Pressure regulation: outlet transducer closes the drive-air valve at setpoint; excess pressure is bled safely.
Shutdown & purge: drive-air venting and purge-valve operation clear residual oxygen, avoiding stagnation.

Maintenance & lifecycle

Monthly / 500 h: inspect filters, hoses and relief-valve settings.
Quarterly: calibrate transmitters and dew-point sensor; test interlocks.
Annual: full oxygen-clean re-certification; dynamic seals and hose hydro-test to 1.5× MAWP.
Spares kit: O-rings, filters, relief cartridges, transducer module, PLC backup.

Optional modules & customization

Redundant booster skid: auto-switchover for uninterrupted operation.
Gas blending package: precise O2–N2 mixtures via mass-flow controllers.
Remote monitoring: cloud telemetry with SMS/email alerts, dashboard analytics, MQTT/OPC-UA.
Climate-controlled enclosure: IP55 cabinet with heater/AC for −20°C to +55°C environments.
Mobile configuration: wheel-mounted frames, fold-down skid arms, shock isolation.

Installation & commissioning

Plug-and-play piping: ISO 8434 quick-connect fittings, reducing hook-up time to under 2 hours.
Factory acceptance testing: pneumatic endurance run, PSIP report, witness video.
Site survey & layout: 2D/3D CAD for placement, ventilation and service access.
Operator training: two-day on-site course covering operation, maintenance and emergency procedures.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 What is the Oxygen Gas Boosting System?

The Oxygen Gas Boosting System is a compact, skid-mounted unit built by Neometrix Engineering Pvt Ltd, India, that elevates oxygen pressure up to 350 bar (about 5,000 psi) using only plant air (3–7 bar) as the drive medium, eliminating electrical ignition risk for oxygen service.

Q · 02 How does the system boost oxygen without electrical ignition risk?

The booster is driven entirely by plant compressed air (3–7 bar) acting on a piston assembly isolated by stainless membranes, so no electrical components contact the oxygen path. A fully pneumatic version is intrinsically safe; an optional ATEX Zone 2-rated electric drive is available where hybrid operation is required.

Q · 03 What inlet and outlet pressures does the booster handle?

The system accepts an oxygen inlet pressure of 20–120 bar and boosts it to a maximum outlet pressure of 350 bar (about 5,000 psi), delivering up to 20 Nm3/h at 200 bar or 5 Nm3/h at 350 bar.

Q · 04 What oxygen purity and dew point does it maintain?

An inline oxygen analyzer and moisture sensor maintain output purity above 99.5% O2 with a dew point below −40°C after filtration, meeting medical and semiconductor-grade requirements.

Q · 05 Is the Oxygen Gas Boosting System oxygen-clean certified?

Yes. All wetted parts, hoses, gauges and vessels are cleaned and certified to ASTM G-93 for oxygen service, with hydro-tested, certified hoses and calibration certificates supplied with each unit.

Q · 06 What safety devices protect the system against overpressure?

Mechanical safety-relief valves set at 210 bar protect against overpressure, backed by an automated post-shutdown purge sequence that clears residual oxygen from the system before it is opened for service.

Q · 07 What certifications and standards does the system meet?

The Oxygen Gas Boosting System is designed to CE and ISO 13485 requirements, built with ASTM G-93 oxygen-clean construction, and available in an ATEX Zone 2-rated configuration for hazardous-area operation.

Q · 08 How quickly can the system be installed on site?

ISO 8434 quick-connect fittings and a pre-piped, forklift-pocketed skid reduce hook-up time to under two hours, with factory acceptance testing, a PSIP report and witness video completed before dispatch.

Q · 09 Can the Oxygen Gas Boosting System be customized?

Yes, Neometrix offers optional modules including a redundant booster skid for auto-switchover, a gas-blending package, remote telemetry monitoring, a climate-controlled enclosure, and wheel-mounted mobile configurations.
