2. High-purity oxygen compression step

-  After around 2 min from production operation, the bypass step is complete and high-purity oxygen 

pressure step is to compress high-purity oxygen discharged from the individual oxygen unit to the 

oxygen storage tank with high pressure through the booster compressor. Then, the pressure gauge 

values of the oxygen storage tank and oxygen discharge pressure at the control panel are increased 

gradually and oxygen is supplied to the gas pipe through the flow meter. 

(The discharge pressure of high-purity oxygen pressurized in the oxygen storage tank through the 

regulator in this product is set to 4.0 bar when it is shipped. It takes around 8 min in maximum to 

reach at this value and it differs according to a flow rate used in the final end.

<High-purity oxygen compression step>

The flow meter and two types of pressure gauge increased gradually

Normal operation step - High purity oxygen supply step

After around 10 min from production operation, high purity oxygen compression step is complete and the 

highest purity oxygen of about 93% to 94% is supplied regularly and constantly through the gas pipes. 

The oxygen discharge pressure gauge is set to around 4.0 bar so no changes in pressure while the oxy-

gen tank pressure meter varies between 4.4 and 6.4 bar continuously.

<High-purity oxygen supply step>

Discharge flow rate and oxygen discharge pressure are increased to the highest,

Oxygen tank pressure is entered to normal pressure.
