Liquid oxygen

450Nm³/hr

(642Kg/hr, 562L/hr)

99.6% O₂

0.05MPa G

Sub cooled to reduce vaporization when transfer to storage tank

Gas nitrogen

450Nm³/hr

(562Kg/hr)

10 ppm O₂

Mode 2:

Liquid oxygen

225Nm³/hr

(321Kg/hr, 281L/hr)

99.6% O₂

0.05MPa G

Sub cooled to reduce vaporization when transfer to storage tank

Liquid nitrogen

225Nm³/hr

(281Kg/hr,347L/hr)

10 ppm O₂

0.45MPa G

Sub cooled to reduce vaporization when transfer to storage tank

Note:

1. The output flow Nm³ is same to input air flow Nm³ after air purifier. Normally Nm³ means volume under standard conditions (0 deg C, 0.1013 Mpa.A). If the input dry air flow after purifier is supplied by buyer in Sm³ (20 deg C, 0.1013 Mpa.A), the output shall be adjusted to Sm³ technically and accordingly. 

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

3. Standard industrial performance tolerance: Output: + 4%      Purity: 0%
