Features & Benefits
Cabinet
n
Rust-free, all-aluminum white case with louvered intake
grille for attractive appearance
n
Statically and dynamically balanced fans are designed for
quiet air movement
n
All factory installed electrical components are wired to
a terminal board in the junction box making field wiring
quick and easy
n
Inlet connection allows for external mounting of TXV
Coil
n
Sweat-type cooling coil connections reduce the potential
for leaks
n
Nickel-steel alloy heaters provide a positive defrost and
have long life
n
Electric defrost coils have a hermetically sealed defrost
termination thermostat that does not require adjustment�
Hot gas defrost units come with an adjustable defrost
termination thermostat
n
Cross-fin cooling coils with corrugated aluminum fins
spaced 6 FPI & 3/8” OD staggered copper tubes
provide optimum heat transfer and reduce the amount of
refrigerant required
n
Generous coil surface helps to maintain steady room
temperature and minimize product shrinkage
n
Access port on the suction connection allows superheat
to be easily and accurately set
Low Flow unit coolers are ideal for meat storage and preparation rooms, floral coolers, dough retarding and many other applications
requiring low air velocities and low sound levels� With low velocity unit coolers, high humidities can be maintained to prevent product
drying and weight loss� These units are ideal for any type of workroom where human comfort is important�
Drain Pan
n
Hot gas models use inner drain pans with low-wattage
electric heaters� This eliminates the braze joints and
tubing associated with hot gas drain pan loops
n
All models use inner drain pans to reduce sweating
Motors
n
Motors are factory-wired to unit junction box for fast
installation
n
Thermal overload protected motors are resiliently
mounted inside the unit to assure minimum noise level
n
High efficiency PSC motors are optional on sizes 070
through 170� PSC motors are standard on sizes 190
through 270
n
EC Motors (optional) available factory-installed or as a
drop-in replacement through InterLink™ Commercial
Refrigeration Parts in 115/1/60 and 208-230/1/60
