TS32 USER MANUAL
NOTE
The "waste heat" from air-cooled com-
pressors can be used for local space
heating. If it is used for this purpose, the
additional static pressure drop across the
fan should not exceed 0.2 in. H
high static fan option is required if duct-
work is added. Contact Sullair Customer
Care for additional information.
NOTE
Housing the compressor in an inade-
quately ventilated enclosure will cause
higher compressor operating tempera-
tures.
NOTE
Systems using both reciprocating and
rotary screw compressors must isolate
the two types from each other through the
use of a common receiver tank. Air lines
from each individual compressor should
be connected directly to the common
receiver tank.

OMPRESSORS
• Water-cooled compressors require a cool-
ing water supply delivered at a constant
rate and volume. (See Table 4-1:Water
Flow Requirements. The table data applies
to full load operation using an aftercooler.)
• Compressor water input and return lines
must be sized as a minimum to match the
compressor water connection size, and
have isolation valves with side drains. The
input water line should have a 2mm
strainer installed in-line. A solenoid valve
