Features & Benefits
Low Flow unit coolers are ideal for meat storage and preparation rooms, oral 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.
Cabinet
Rust-free, all-aluminum white case with louvered intake grille for attractive appearance
Statically and dynamically balanced fans are designed for quiet air movement
All factory installed electrical components are wired to a terminal board in the junction box making eld wiring
quick and easy
Inlet connection allows for external mounting of TXV
Coil
Sweat-type cooling coil connections reduce the potential for leaks
Nickel-steel alloy heaters provide a positive defrost and have long life
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
Cross-n cooling coils with corrugated aluminum ns spaced 6 FPI & 3/8" OD staggered copper tubes provide optimum
heat transfer and reduce the amount of refrigerant required
Generous coil surface helps to maintain steady room temperature and minimize product shrinkage
Access port on the suction connection allows superheat to be easily and accurately set
Drain Pan
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
All models use inner drain pans to reduce sweating
Motors
Motors are factory-wired to unit junction box for fast installation
Thermal overload protected motors are resiliently mounted inside the unit to assure minimum noise level
High eciency PSC motors are optional on sizes 070 through 170. PSC motors are standard on sizes 190 through 270
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
Options
Units available with copper fins. Air defrost units also available with polyester coated fins or various coil coatings options
