Conair MPA Refrigerator User Manual


 
The microKool portable chillers are designed to provide
chilled water for industrial applications requiring 24-hour-a-
day performance.
Operation of air-cooled and water-cooled units differ only in
the medium used to remove heat from the refrigerant in the
condensers.
Water-cooled models use 85° F (29° C) cooling tower water,
and are equipped with high efficiency tube-in-tube condensers
with water regulating valves.
Air-cooled models use 95° F (35° C) ambient air and alu-
minum-fin, copper-tube condensers. Units above 1.5 Hp
include automatic fan cycling controls.
Units are totally self-contained for easy, economical installa-
tion. To operate, simply connect the power source, process
piping and fill with water or an industrial antifreeze mixture.
The standard PC-1 microprocessor control displays setpoint
and actual temperature of the process fluid, and provides SPI
communication. Nine operating and fault indicator lights dis-
play the status of the chiller components.
The enhanced PC-2 control offers the same features as the
standard control plus autostart capabilities, which enables the
chiller to start automatically with a timing device or the start-
ing of the primary process machine.
These chillers are ideal for cooling to maintain process tem-
peratures in an injection molding machine or extruder and
wherever you need a small, moveable cooling unit.
Capacities range from 1.2 to 10.2 tons. Standard operating set-
points are between 20° F (-7° C) and 65° F (19° C) LWT.
Adequate freeze protection is required.
Choose water-cooled portable chillers:
for maximum capacity and minimal maintenance.
when maintaining ambient air temperature is important,
such as an air-conditioned environment.
when tower water or another inexpensive water source is
available.
Choose air-cooled portable chillers.
when plant water supply is inadequate or limited.
when process heat must be extracted and used for space
heating.
