6.1 WATER SYSTEM
A. MOTOR/PUMP ASSEMBLY: the
motor/pump assembly circulates
chilled fluid to the process loop.
The pump assembly is built of total
stainless steel to maintain water
quality (figure 6.1A).
B. FLOW SWITCH: the flow switch is
a paddle-type switch mounted in
the from process water line. The
primary function of the flow switch
is to monitor water flow. If the flow
drops 33%, the switch will stop the
refrigerant circuit. This protects the
evaporator from freezing due to
low flow (figure 6.1B).
C. FREEZESTAT: the freezestat aids in
protecting the evaporator from
potential freezing. The freezestat is
factory adjusted to 40°F. The
freezestat must be field adjusted for
operating with setpoints below
48°F (figure 6.1C).

REFRIGERATION SYSTEM

A. COMPRESSOR: hermetic or semi-
hermetic compressors take low
pressure/low temperature
refrigerant gas and compress the
gas into high pressure/high
temperature gas (figure 6.2A).
B. AIR COOLED CONDENSER: the air
cooled condenser removes BTU's
from the compressed refrigerant
gas. The action causes the gas to
"condense" into a liquid state still
under high pressure. Air flow across
the condenser is achieved via a
motor driven fan assembly or
centrifugal blower (figure 6.2B).
C. FILTER-DRIER: the filter-drier
removes contaminants and
moisture from the liquid refrigerant
(figure 6.2C).
