Engineered for PSA & VPSA Process Reliability
When your PSA oxygen plant, hydrogen purification unit, or carbon monoxide recovery system demands a compressor that runs continuously without compromise, the performance envelope of our product range — spanning output from 2 to 500 Nm³/min at pressures from 0.1 to 6.00 MPa — means you are never forced into a gap between what your process requires and what the compressor can deliver. These machines are not catalogue products selected from a standard shelf; they are application-matched units built around the specific gas, pressure ratio, and duty cycle of each installation. Every cylinder configuration — Z-type, M-type, D-type, P-type, and L-type — is selected to match flow geometry and eliminate unnecessary crosshead loading. The result is a compressor that stays within its designed stress envelope across years of continuous operation, which is exactly what PSA cycle times and VPSA process logic demand.
Across nine models covering oxygen, hydrogen, and carbon monoxide gas streams, this product range represents a complete technical answer to the compression challenges faced by industrial gas producers and processors operating in the United Kingdom’s demanding regulatory and operational environment. Whether you are upgrading an ageing plant in the Midlands, commissioning a new steel works oxygen supply in South Wales, or installing a hydrogen compression stage for a green energy project in Scotland, the engineering approach remains consistent: match the machine precisely to the gas and the duty, then build it to last.

Cara Kerja Kompresor Gas Ini
Reciprocating Piston Action
Gas enters the cylinder through a suction valve, is compressed by the piston stroke, then discharged through a delivery valve at the target pressure. Multi-stage configurations handle high-ratio compression without excessive thermal loading between stages, protecting gas purity and mechanical life.
Gas-Specific Sealing
Oxygen compressors use PTFE piston rings and oil-free cylinders to prevent combustion risk. Hydrogen models employ labyrinth piston rings and dual mechanical seals with nitrogen purging between them. Carbon monoxide units are sealed with all-metal valve plates and pressure-tested to leak-before-break standards.
Materials Engineering
Cylinder barrels are cast from close-grained grey iron or nodular cast iron depending on pressure class. Crankshafts are forged alloy steel, finish-ground and dynamically balanced. Crossheads are aluminium alloy in lighter frames, nodular iron in high-force applications. All wetted surfaces in contact with reactive gases receive appropriate degreasing, passivation, or coatings before assembly.
Typical Application Scenarios
PSA oxygen plants feeding electric arc furnaces; VPSA units supplying waste-water treatment aeration systems; hydrogen compression for green hydrogen export terminals; carbon monoxide boosters in oxo-synthesis chemical facilities; and CO₂ recovery compression in food-grade carbonation lines — these are the real-world environments these machines are built to handle.
Performance Advantages That Show Up in Uptime
Zero Cross-Contamination
Every gas compressor in this range is designed so that the working gas never contacts lubricating oil. This is a non-negotiable requirement for oxygen purity above 90% and hydrogen used in fuel cell or semiconductor applications, where even trace hydrocarbon contamination disqualifies the product stream.
Jangka Waktu Servis yang Panjang
Valve life of 8,000+ hours and piston ring change intervals exceeding 12,000 hours are standard expectations across the range. This is achieved through conservative stress design, hardened valve seats, and the use of self-lubricating ring materials that do not degrade in reactive gas environments.
Fleksibilitas Tekanan yang Luas
A single compressor family covering 0.1 MPa through to 60 MPa outlet means a plant designer can source PSA feed compression, buffer storage compression, and cylinder filling compression from the same engineering team with compatible spare parts philosophy — a significant advantage for UK plants managing multi-product gas supply.
Low Foundation Loads
Balanced-opposing cylinder configurations in L-type and D-type models reduce unbalanced inertia forces by over 80% compared with in-line alternatives. This matters in retrofit projects inside existing UK process buildings where foundation modifications are restricted by structural or heritage constraints.
Variable Frequency Screw Air Compressors
For instrument air, plant air, and general utility gas compression alongside your PSA/VPSA plant, consider these energy-saving screw air compressor options:
CM90PVF Variable Frequency Screw Air Compressor
90 kW inverter-driven screw compressor with permanent magnet motor — delivers up to 35% energy savings over fixed-speed alternatives in part-load operations typical of PSA air feed duty.
Kompresor Udara Sekrup Kecepatan Variabel CM45PVF 45kW
Compact 45 kW variable speed screw air compressor suited to smaller PSA oxygen generators, laboratory air systems, and process utility supply in UK industrial and commercial settings.

Electric Arc Furnace Oxygen Enrichment — DW-70/8 Installation
A Sheffield-based special steel producer needed to increase oxygen injection capacity for their twin-shell EAF by 40% without modifying the existing PSA plant structure. The engineering brief called for a gas compressor capable of accepting PSA product gas at approximately 0.15 MPa and discharging at 8 MPa for pipeline injection — conditions the DW-70/8 was designed around. Installation was completed within a 10-day planned shutdown window. Since commissioning, the unit has logged over 14,000 operating hours with one scheduled valve maintenance intervention, and furnace tap-to-tap time has improved by 8% due to more consistent oxygen injection pressure.
8% efficiency gain
10-day installation
We have operated PSA oxygen plants for twelve years. This is the first gas compressor we have installed that has gone through an entire maintenance contract period without an unplanned shutdown. The oil-free cylinder design is exactly what our process requires, and the engineering support during commissioning was genuinely impressive.
We shortlisted four suppliers for our hydrogen compression stage. The technical data provided was the most detailed, and the willingness to customise the seal arrangement for our specific inlet purity level — something the other suppliers said could not be done at this flow rate — made the decision straightforward. The 4MW-19.5/1.5-60 has operated flawlessly since day one.
Our waste-water treatment facility expanded its VPSA oxygen capacity by 60% using two ZW-50/3.5 units in a lead-lag configuration. The compact footprint compared with the alternative D-type unit we had costed was a deciding factor given our limited plant room. Lead times were met, documentation for the UK PED conformity assessment was complete on delivery, and after-sales response has been rapid.
Precision Manufacturing — Full Customisation Capability
The manufacturing facility operates CNC machining centres with bore tolerances to H7/p6 fit, a dedicated gas compressor assembly area with clean-room-equivalent degreasing and passivation bays, and in-house hydrostatic pressure testing to 1.5x rated working pressure for every cylinder and pressure vessel. All crankshafts are dynamically balanced on site to G2.5 ISO 1940 grade. This level of in-house control means that customisation is not a special service — it is standard practice.
Custom work regularly supplied to UK customers includes: non-standard discharge pressures, bespoke flange and pipework arrangements to match existing plant, modified cylinder bore and stroke combinations for specific flow requirements, ATEX-rated motor and control panel integration, dual-language documentation (English and Mandarin) for commissioning handover packages, and bespoke FAT (Factory Acceptance Test) procedures agreed with the client’s technical team before manufacturing begins. If your application sits outside the standard model range, contact the engineering team — a custom gas compressor specification can typically be confirmed within five working days.
Common Questions from UK Buyers
What is the typical lead time and price for an oxygen compressor supplied to a UK industrial facility?
Standard models within the 2–70 Nm³/min range typically carry a lead time of 8–12 weeks ex-works, with delivery to UK mainland ports adding 3–4 weeks depending on shipping schedule. Pricing depends on model, pressure class, and any customisation requirements — please email [email protected] with your flow rate, inlet pressure, and discharge pressure for a quotation within two working days.
Which gas compressor models are best suited for a PSA oxygen plant producing medical-grade oxygen in the United Kingdom?
For medical-grade PSA oxygen applications in the UK, the ZW-6/3 (small-scale), ZW-50/3.5 (mid-scale), and LW-69/0.15–3.6 (high-flow, low vibration) are the most commonly specified options. All three use PTFE piston rings in an oil-free cylinder design, meaning gas purity is not compromised by lubricant carryover. Compliance documentation for UK regulatory submissions is available on request.
How do I know which cylinder configuration — Z-type, M-type, D-type, P-type, or L-type — is the right one for my hydrogen compression application?
Configuration selection is driven by four factors: required flow rate, compression ratio, available footprint, and foundation load limits. Z-type suits lower flows with simple foundation requirements. M-type and D-type handle higher flows and greater pressure differentials with better balance. L-type is specifically beneficial where horizontal vibration transmission to adjacent structures must be minimised — common in hydrogen plant situations inside process buildings. Our engineering team will confirm the optimum configuration once they have your process data.
Where can I get a cost estimate and technical datasheet for a carbon monoxide compressor for a chemical plant project in the UK?
Email your enquiry with process conditions (gas composition, flow, inlet and outlet pressures, duty cycle) to [email protected]. You will receive a budgetary cost estimate and a full technical datasheet for the 4MW-140/7.3 Carbon Monoxide Compressor, or an alternative model recommendation if your conditions better match a different unit, within two business days. All CO compressor enquiries are handled by application engineers with hazardous gas process experience.
Can these gas compressors be supplied with ATEX certification for use in explosive atmosphere zones in a UK refinery or chemical site?
Yes. ATEX-rated motors and junction boxes are available as standard options across the hydrogen and carbon monoxide compressor range. Zone classification (Zone 1 or Zone 2) and gas group must be specified at the enquiry stage so the correct motor, sealing, and control panel specification is confirmed. The ATEX documentation package includes the conformity declaration, technical file reference, and marking details required by UK DSEAR regulations.
What maintenance schedule should I plan for a VPSA oxygen compressor operating continuously at a UK waste-water treatment plant?
For continuous 24/7 operation at a waste-water treatment site, a practical schedule for units such as the ZW-50/3.5 would be: oil and filter change at 1,000 hours (if oil-lubricated drive end), valve inspection at 4,000 hours, piston ring measurement at 8,000 hours with replacement if wear exceeds limit, and a full overhaul inspection at 16,000–20,000 hours. Spare parts kits covering one full valve and piston ring set are recommended to be held on-site. We supply maintenance manuals in English and can provide remote video support during UK-based planned outages.
When is the 3ZW-50/0.15-11 Oxygen Compressor the right choice over the ZW-50/3.5 for a cylinder filling station application in England?
The 3ZW-50/0.15-11 is the appropriate choice when your PSA unit delivers oxygen at near-atmospheric pressure (0.15 MPa) and you need to boost it all the way to 11 MPa for direct cylinder charging. This is a higher pressure ratio than the ZW-50/3.5 is designed to handle — the three-throw Z-type architecture of the 3ZW breaks the compression into three stages, managing interstage temperatures and keeping each stage within its mechanical design envelope, which is essential for oxygen compression safety at high pressures in UK BCGA-compliant filling facilities.
