(1) The PSA process is an extremely clean operation and the only ‘raw material’ is air. (2) Gas production can be done right away when and where it is needed with exact quantity and quality needed. (3) No loss of production time due to running out of bottled gas (4) Quick pay-back: only 0.5~1.5 years (5) No on-going costs (refilling, delivery and transportation charges etc.) (6) Energy efficient. Only electricity is needed to run the N2/O2 generators. (7) No safety risks of handling of high pressure cylinders. (8) In comparison with cylinder N2/O2 it gives overall cost reduction up to 80%. (9) Safe delivery; controlled flow and uninterrupted N2/O2 supply.

From the two adsorption curves below, while the adsorption pressure is increasing, the adsorption capacity of oxygen and nitrogen molecular by the absorbent increase together. But at certain point, the oxygen molecule reaches the adsorption balance point, which is faster than that of nitrogen molecule, resulting in their different characteristics to do the separation. The nitrogen/oxygen PSA system bases on this characteristic of selectivity adsorption and utilizes two CMS/ZMS adsorption beds which are pressurized during working to adsorb the Oxygen/Nitrogen, and depressurized to regenerate. The alternating working cycle will continuously produce high purity gaseous nitrogen/oxygen.

CanGas® typical PSA system is composed of PSA generator with a control unit and oxygen monitor. The complete operating system also requires air package consisting of air compressor, air dryer, filters, air-receiving tank and product N2/O2 tank.

CAN GAS PSA systems help you save money on your oxygen/nitrogen gas costs and allow you to produce gas on-site. Simple and cost effective from a supply of compressed air, it helps you avoid rental charges, transportation expenses or limitations, labour costs and so on.

Ambient conditions at the place of installation are very important on the performance of a PSA system. Temperature: has a significant impact on compressor and dryer performance. The ambient condition of inlet air to the air compressor affects the net weight of the final delivered compressed air to the system. Increases in ambient air temperature reduce the efficiency of air compressors and air dryers. Proper ventilation and ducting of the “compressor room” is required to maintain inlet air temperatures within design specifications. Design working temperatures shall be maintained if the compressors/dryers/boosters are air cooled. Altitude: Altitude increases, the weight of the atmosphere will be less, resulting in less oxygen or nitrogen in the air for air separation, then compressor will need more power to pump same amount of air as that in flat areas. If you are high in altitude, then you need to oversize the compressor. Humidity: Humidity affect is not as dramatic as rise in altitude or temperature. However, extremes need to be taken care of and proper measures shall be taken out.

CAN GAS PSA N2/O2 generators require negligible or little maintenance. The major maintenance is required by air compressor and this can be serviced locally anywhere. Filter elements need to be replaced based on maintenance schedule. Please contact CAN GAS service department for spare parts and maintenance.

The on-site PSA gas generator systems are eco-friendly as one can save a lot on transportation of purchasing cylinder gases and unnecessary green-house gas emissions. With on-site PSA gas generator systems you can make your own gas anytime whenever there is a need, this no need to store large quantities of high pressure cylinders and hazardous gas and moreover handling of high pressure cylinders is eliminated.

In order to ensure long-term stable and reliable operation of the nitrogen or oxygen generator system equipment, some routine maintenance work must be done. The main ones include: whether the solenoid valve works normally; whether the pipelines and pipe fittings of the system are damaged or leaked; whether the electrical control part of the system is securely connected, whether the electrical components are normal.
