Unit cabinets are constructed of heavy duty aluminum, thoroughly reinforced with riveted gussets.
Fan outlets provide additional strength to fan panel and assure even air flow for quiet operation.
Mounting legs are constructed of heavy duty aluminum and are shipped with the unit for field installation.
The condensing unit contains a scroll compressor with crankcase heater, filter drier, sight glass and condenser coil. The condenser coil is constructed of plate type die formed, aluminum fins mechanically bonded to copper tubes and employ full height, self-spacing collars which completely cover the tube surface. The coil is pressure and leak tested at 425 PSIG air under warm water, evacuated, dehydrated, and sealed with caps on connections.
Propeller type fans, carefully matched to the coil, cover a large percentage of the coil face area providing a uniform air distribution. The direct drive fans have heavy duty gauge aluminum blades securely riveted to zinc plated, chromate treated center hubs. All fans are statically and dynamically balanced before shipment and operate at low tip speeds for minimum vibration and low sound levels.
The fan motors are heavy duty PSC or three phase motors with permanently lubricated ball bearings. All motors are thermally protected against burn-out and may be started by a single contactor. Protective slingers shield the motors from weather damage.
All motors are factory wired with leads terminating in a weather protected junction box located on the outside of the unit casing. Fan motors are _ horsepower, 1075 RPM.
The fan guards are constructed of heavy gauge, close meshed steel wire powder coated for corrosion resistance.
All Data Aire DRCU type condensing units are E.T.L. listed.
