Lab Use Nitrogen Generator Gas Generation Machine

Lab Use Nitrogen Generator Gas Generation Machine is a mass manufactured small Nitrogen Gas plant designed for lab device application. 

Why choose Gamma, not other suppliers?

High reliability

For PSA Oxygen Generators, the most important factor is equipment operation reliability, especially for overseas market, where maintenance and repair service should be minimum. Keeping the equipment run at the designed purity and flow rate without malfunction is of critical importance.

Similar to other suppliers, Gamma Gas manufactures PSA nitrogen/oxygen generators, but unlike other suppliers, Gamma is using the most advantage process and special equipment structure to ensure long time operation stability.

Now in China,  there are many companies manufacturing PSA N2/O2 generators, but how many of their products are running without purity decrease? without flow rate drop? without problems such as molecular sieve ejection,etc. Gamma Gas strongly recommend customers to contact us for more details.

Energy-saving

As PSA N2/O2 generator itself consumes very little power, the main power consumption is the Air Compressor. Compared with other suppliers, for same flow rate and purity, with Gamma's special process and structure, the compressed air needed is about 20% less, therefore smaller air compressor is needed. Considering years non-stop operation, Gamma this energy-saving feature also brings remarkable benefits for our customers.

Please send us your detailed or even brief requirements, Gamma will show you the difference between ordinary and excellence.

It uses pressure swing adsorption technology, with this technology, nitrogen is separated from air as product gas.  This psa nitrogen gas plant has small size, it has four wheels at the bottom, it can be moved from one place to another easily.

2.10. Solenoids

The solenoids on the gas control valves is 24 VDC.

2.11. Operation

2.11.1. Operating cycle

A typical operating cycle for the Generator is 1 start per day and then run for 8 hours per day, which is equivalent to 2000 hours of operation per year. Depending upon the particular site, operating time could be anywhere between 0 and 24 hours per day.  

2.11.2. Operation at shutdown

When the power is turned off, the pressure vessels is maintained in the pressurized state by closing the two exhaust valves.  

2.12. Start up

12.1. Start up time

Start up times means the time from start up to producing qualified nitrogen.

The time to complete start up is less than 15 minutes.  

2.13. Gas connections

The two external gas connections on the Generator, Air In and N2 Out, are constructed from brass and are to suit ¼" (6.35 mm) OD tubing. There are labeling in English next to these connections, [Air In" and [N2 Out", as part of the rating label.

2.14. Environmental requirements

2.14.1. Operating temperatures

The Generator is normally operated within performance specification over the temperature range:

10ºC - 35ºC from 0 – 3000 m, and 10ºC - 25ºC from 3000 – 4500 m

The Generator can operate safely over the temperature range:
