Unit Cabinets are constructed of heavy duty gauge corrosion resistant steel with a powder coated finish, 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 steel and are shipped with the unit for field installation.

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 DARC type condensers are E.T.L. listed.

Low Decibel DARC-LD Condenser Capacities

Cabinets are constructed from 14 gage welded tubular steel and are coated with a heavy corrosion inhibiting finish for long life. The unit has complete front and side access by means of high quality furniture grade steel panels with heavy duty hinges. The panels are lined with 1 inch thick, 1.5 pound density insulation. Each door is provided with sure close latches. Cabinets are painted to match or contrast with other equipment in the space.

The blower is a belt driven centrifugal type, double width, double inlet and is statically and dynamically balanced as a complete assembly to a maximum vibration level of two mills in any plane. The blower wheel is supported on a haevy steel shaft with self-aligning ball bearings with minimum life span of 100,000 hours. The blower is driven by a motor mounted on an adjustable slide base. The drive motor is 1750 RPM. The drive package is belt driven with dual belts and a variable pitch sheave sized for 200% of the fan motor horsepower. A factory mounted and wired disconnect is optional.

The condenser coil is constructed with copper tubes and aluminum fins. The coil is equally circuited to match each refrigeration compressor. The coil sits in stainless steel drain pan. A receiver with pressure control and solenoid valves is provided for each circuit. All refrigeration piping terminates inside the unit cabinet. Standard refrigeration piping is through the bottom of the unit. Options are available for either top piping or side piping with short right hand side door.

Air intake is horizontal. Standard discharge is horizontal with top air discharge available as an option. An optional integral filter rack with 4″ thick, 30% efficient filters (based on ASHRAE Std. 52-76) is available for the air intake.
