Table 2 shows the estimated charge weights for each compressor circuit in STULZ condensers. A
receiver is included with the condenser if it is designed for applications where ambient conditions may
drop to -30°F or lower. When selecting the condenser refrigerant weight from Table 2, determine if your
condenser includes a receiver and ensure you select the charge weight from the correct column in the
table.
