Technical Data
S-ORC (Sensitive Oxygen Ratio Controller)
S-ORC is a control element which guarantees a minimum O2 concentration in the fresh gas flow. As
from a flow rate of approx. 300 mL/min, the N2O concentration in the fresh gas can be freely set
between 0 and 75 %.
During O
2 shortage S-ORC limits the N2O concentration in the fresh gas, so that the O2 con-
centration does not drop below 23 vol.%.
N
2O metering valve open
and O2 metering valve
closed or O
2 flow less than
0.2 L/min
S-ORC prevents N
2O flow
During N2O failure O2 may still be administered. No alarm.
