S-ORC (Sensitive Oxygen Ratio Controller)
S-ORC is a control element which provides a mini-
mum O

2
a flow rate of approx. 300 mL/min, the N
tration in the fresh gas can be set between 0 and
75 %.
During O
shortage S-ORC limits the N
2
tration in the fresh gas, so that the O
does not drop below 23 vol.%.
S-ORC prevents N
O flow if the N
2
valve is open and O
metering valve closed or if the
2
O
