Is there any site with CanGas® PSA systems installed that I can visit?
Positive. 4,000+ CanGas® PSA systems are installed and running well all around the world. Please contact us to find the nearest CAN GAS system in your region for visit and assessment.
Do you have a reference list?
Yes. As more than 4,000 sets of CAN GAS systems are currently in operation around the world, it is difficult to list them one by one on our website. Please contact CAN GAS for the reference list.
What is the maintenance cost of CanGas® PSA systems?
CAN GAS PSA systems offer high reliability Nitrogen or Oxygen production through fewer moving parts with high quality components and negligible maintenance. Only the air filter elements in PSA need to be replaced based on a maintenance schedule. The major maintenance is for air compressor.
What is the power supply requirement for CanGas® PSA systems?
CanGas® PSA systems require only about 0.1 kW at 60~240V AC or DC, 50 or 60 Hz, 1 Phase.
Can I use air compressors with an integrated air dryer?
Surely. It saves space at user jobsite without any compromise in quality or performance.
Why do I need an air dryer?
An air dryer assures that air is supplied at the proper dew point for the good & reliable performance of PSA N2/O2 systems. The air dryer is used to remove the water in compressed air, in order to avoid that feed air with too high water content getting into the molecular sieve. If air dryer stopped working or failed, the molecular sieve will get contaminated and PSA nitrogen/oxygen generator will eventually be damaged.
How does PSA work to produce Nitrogen Gas or Oxygen Gas?
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.
What are the main benefits of CAN GAS N2/O2 Generators?
(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.
Is it necessary to change the molecular sieve of PSA N2/O2 generators?
As long as the feed air is with good quality, the CAN GAS PSA generators do not need any renewal of the molecular sieves, thanks to best quality molecular sieves used for all CanGas® PSA generators.
