CAPACITY CONTROL
Each compressor can modulate from 100% to 30% of full
load by slide valve operation. This provides reduction down
to 7.5% on four-compressor units.
Further reduction is possible on all units through use of
the hot gas bypass option which reduces compressor capac-
ity to 10%. Minimum capacities are tabulated below.
