Figure 11 Extract from the injector data sheet

For the operation of an installed bypass injector, the necessary pressure must be set on the pres-
sure regulator (see figure 12).
N O T E !
The attached bypass injector table shows the suction flows at cor-
responding bypass gas pressures for two different process pres-
sures, 1 bar and 0,9 bar absolute (see figure 12).

In the event of low temperature (failure of the heating) the supply of
dilution gas must be interrupted!
