2.1 Description of Figures 1 - 4
• Figure 1 shows the general standard once through arrangement with integral dis-
charge separator manifold.
• The arrangements of figure 2 (partial recirculation) and 3 (total recirculation) are for
handling combustible, corrosive and explosive gases as well as the gas which is re-
quired to be recycled. If the working liquid is recirculated in the system as shown in
figure 3, then a heat exchanger should be used for cooling the liquid.
• Figure 4 (option for LR 0420 A and LR 0580 A only) shows the arrangement where
gas and water leave from the side flange of the vacuum pump and discharge directly
into the gutter.
