Technical Data
S-ORC (Sensitive Oxygen Ratio Controller)
S-ORC is a control element which guarantees a minimum O
2
concentration in the fresh gas flow. As
from a flow rate of approx. 300 mL/min, the N
2
O concentration in the fresh gas can be freely set
between 0 and 75 %.
During O
2
shortage S-ORC limits the N
2
O concentration in the fresh gas, so that the O
2
con-
centration does not drop below 23 vol.%.
