Features & Benefits  
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.  
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 field 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-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  
• 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 efficiency 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
