Note:

1. Nm³ means volume under standard conditions (0 deg C, 0.1013 MPa.A)

2. The performance is based on design basis of item 1 in this technical annex.

3. Standard industrial performance tolerance:

    Output: + 2%      Purity: 0%

4. This performance is under warranty.

5. The output flow shall be able to adjust 80~100%.

6. Both liquid oxygen and liquid nitrogen should have nozzles to connect to liquid tanks.
