Products

• O200 Nordic — Oxymat: Modular PSA oxygen generator built around two standard size pressure vessels, aimed at sites needing a continuous oxygen supply in a small footprint. Typical duties are aquaculture aeration and wastewater treatment, with Modbus RTU communication and LED operating status.
• O200 Nordic Supreme — Oxymat: Higher capacity version of the O200 modular PSA oxygen range, available in four vessel configurations. It suits aquaculture, wastewater and ozone duties where oxygen demand grows over time, since capacity is added by extending the same frame.
• O60 Nordic — Oxymat: Euro-pallet sized PSA oxygen generator with built in filters, so it arrives ready to connect. It is used for oxygen supply in healthcare and for aeration in fish farming where the unit has to be moved or installed in a tight plant room.
• O60 Nordic Supreme — Oxymat: Upgraded O60 pallet PSA oxygen generator giving higher output and lower power draw from the same footprint. Oxymat states it uses 40 per cent less zeolite than the standard unit, and it keeps the plug and play filter arrangement.
• Half pallet Nordic oxygen generator — Oxymat: Half euro-pallet PSA oxygen generator for low flow duties, light enough to move by hand pallet truck. It is used for ozone generation in wastewater treatment and other applications where floor space is limited, and it carries MDD approval.
• Twin-Tower oxygen generator — Oxymat: Skid mounted two column PSA oxygen plant covering a wide capacity band from a single design, with MDR approval for medical supply. The package can be extended with an oxygen booster and cylinder filling station, or built into a container or frame.
• Compact integrated PSA oxygen generator — Oxymat: All in one cabinet oxygen generator with the air compressor, dryer and oxygen tank built in, so only power and an outlet connection are needed. It suits broodstock and hatchery work in fish farming and other low volume oxygen duties.
• Compact integrated silenced PSA oxygen generator — Oxymat: Compact integrated oxygen generator supplied in a silenced cabinet for locations where noise matters, such as clinics and laboratories. The compressor, dryer and oxygen tank are built in, so the unit runs as a plug and play supply.
• Compact PSA oxygen generator — Oxymat: Low volume PSA oxygen generator in a stainless steel cabinet that mounts on a wall or stands on the floor. A four inch display handles control and performance monitoring, and an external oil-free compressor and integrated oxygen monitor can be added.
• OXYMAT X-series frame-mounted PSA oxygen generator — Oxymat: Frame mounted tonnage PSA oxygen package covering nine models, supplied plug and play with buffer vessels, filters and instrumentation. Oxymat position it as a lower capital cost alternative to a cryogenic air separation unit where footprint is tight.

Oxymat supply these for gold mining, aquaculture, wastewater treatment, medical use and field hospitals, including Arctic, desert and high altitude installations.
• N200 Nordic — Oxymat: Modular PSA nitrogen generator for duties needing a large continuous supply, widely used on marine vessels for inerting, blanketing and purging. The compact frame also suits retrofit work in oil and gas and food and beverage plant.
• Pallet N60 Nordic — Oxymat: Euro-pallet sized PSA nitrogen generator with built in filters for straightforward installation and later relocation. It is used in food and beverage and oil and gas work, and in power plants for purging and corrosion protection.
• Half pallet Nordic nitrogen generator — Oxymat: Half euro-pallet PSA nitrogen generator, light enough to move easily and small enough for constrained plant rooms. It is aimed at nitrogen supply in manufacturing, food and beverage and electronics work.
• Twin-Tower nitrogen generator — Oxymat: Skid mounted two column PSA nitrogen plant with four decades of service history, covering everything from small flows to tonnage duties. A nitrogen booster and cylinder filling station can be added, and the plant can be container or frame built.
• Membrane nitrogen generator NM series — Oxymat: Membrane nitrogen generator with a footprint of just over two cubic metres, supplied in single and double membrane configurations. It starts quickly, needs little maintenance and carries all major marine approvals, which makes it suited to vessel retrofits.
• Compact integrated PSA nitrogen generator — Oxymat: All in one cabinet nitrogen generator with the oil-free compressor, dryer and nitrogen tank built in. It covers low volume duties such as wineries, packaging and fire protection, and mounts on a wall or on the floor.
• Compact integrated silenced PSA nitrogen generator — Oxymat: Compact integrated nitrogen generator housed in a silenced cabinet for quiet operation. The compressor, dryer and nitrogen tank are built in, so the unit only needs power and an outlet connection to run.
• Compact PSA nitrogen generator — Oxymat: Low volume PSA nitrogen generator in a stainless steel cabinet, mounted on a wall or floor with a four inch display for control and monitoring. An external oil-free compressor can be supplied where one is not already available.
• OXYMAT X-series frame-mounted PSA nitrogen generator — Oxymat: Frame mounted tonnage PSA nitrogen package covering nine models, supplied plug and play with buffer vessels, filters and instrumentation. Oxymat report well over one hundred installations of this design worldwide.
• Nitrogen purifier NH 20-400 — Oxymat: Second stage purifier that raises standard on-site PSA nitrogen to ultra-high purity by injecting a controlled amount of hydrogen, which reacts with residual oxygen to form water. It works in series with any PSA nitrogen generator and runs unattended.
• Containerized and in-frame nitrogen generator installations — Oxymat: Nitrogen plant built into a container or open frame for rigs, refineries and remote sites. Oxymat supply ATEX rated units and documentation to nuclear power plant level, with installations running from Saudi Arabia to Greenland and the Himalayas.
• MIDAS-I — Semian: Burn and wet local scrubber that treats process exhaust from semiconductor tools using an LNG fired combustion stage followed by water scrubbing. Up to four gas inlet ports feed one cabinet, which suits multi chamber tools in the sub fab.
