B.
Air flow is generated by the motor mounted fans or centrifugal blowers. Air flow is from
the outside of the chiller, through the condenser and exhausted through the top of the
unit. On centrifugal blowers models, exhaust air can be ducted outside of the plant’s
interior environment. Special duct work is required and a HVAC contractor should be
consulted for sizing and material specifications. Exhaust air can not be ducted on motor
mounted fan models.
C.
A free air space of at least three (3) feet is required
at the condenser intake and six (6) feet at the
condenser discharge to allow for proper air flow.
D.
At full load, the chiller will discharge approximately
15,000 btu per hour for every 12,000 btu/hr removed
from your process 1,000 cfm per horsepower. The
unit will reject 25% - 35% more heat than it removes
from your process.
E.
On blower units, air discharge duct
work should be sized by a qualified
HVAC engineer. Sizing shall be
according to rated CFM at the static
pressure of .90 inches of water.
F.
On blower units, a damper control
assembly is required in low ambient
temperature areas or when outdoor
air make-up is used. The assembly
works in conjunction with refrigerant
head pressure to regulate air flow
to maintain proper refrigerant head
pressure when condenser intake air
temperature will be less than 60°F.
G.
All air cooled units must have all
enclosure panels in place before
operating compressor. Air will not
be drawn through the condenser
coil if the panels are not in place.
Starting the unit without the
enclosure panels in place will result
in a refrigerant fault.

WARNING: Do not attempt to duct exhaust air from a portable chiller using motor driven fans.
Exhaust air can only be ducted from a portable chiller using a blower assembly.
WARNING: Do not attempt to start or operate an air-cooled portable chiller without all cabinetry
panels in place. Air-cooled chillers require air to be drawn through the air-cooled condenser. This
will not occur if the panels are not in place.
