Flow-Temp low air velocity unit coolers are ideally suited for meat cutting, holding and
packing rooms as well as produce storage and florist boxes.
• There are nine models available, ranging in capacity from 5,000 to 34,000 Btuh @ 10° TD
• Rust free heavy gauge embossed Aluminum housing is standard. Optionally available
with alternate materials and coatings.
• Seamless enhanced Copper tubes are staggered and mechanically expanded into
corrugated Aluminum fins assuring maximum heat transfer.
• Optional Copper fins and fin coatings are available.
• Available voltages: 115/1/60, 208/230/1/60, 460/1/60, 100/1/50, 200-220/1/50 and 380/1/50.
• Fan motors and blades can be easily accessed by lowering the hinged drain pan.
• Standard motors are permanently lubricated with thermal overload protection.
• High efficiency EC motors are standard, PSC or shaded pole motors are optionally
available.
• All models are available in air, electric and hot gas defrosts designs.
