S-ORC (Sensitive Oxygen Ratio
Controller)
Fabius is equipped with a mechanical minimum O2
delivery (S-ORC). This safety device prevents
hypoxic gas mixtures if N
2O is selected as the
carrier gas.
Starting at a flow of approx. 200 mL/min, the N
2O
concentration in the fresh gas can be set to a value
between 0% and 75%.
When a lack of O2 is present, the S-ORC limits the
N2O concentration in the fresh gas so that the O2
concentration will not fall below 23 Vol%.
S-ORC inhibits the N
2O flow under the following
conditions:
–N
2O flow control valve is open, even though
the O2 flow control valve is closed.
–O
2 flow is below 0.2 L/min.
With an N
2O failure, O2 can continue to be
supplied. An alarm is not triggered. The float in the
N
2O flow tube drops to zero.
S-ORC has no oxygen-specific monitoring function
and offers no protection for the consequences of
an accidental interchange of gases.
Therefore, the O
2 concentration must always be
monitored.
