"DPV" SERIES VERTICAL INDOOR SYSTEM GENERAL MECHANICAL SPECIFICATIONS

GENERAL

All models 5-15 tons ship as factory-charged unitized packages. The 20 ton model shall be shipped as separate evaporator and condensing unit modules (nitrogen holding charge only). All units may be field split and installed as separate modules to suit on-site requirements. All packages are designed for free- standing mounting on the floor, or on a field fabricated structural steel stand. The 5, 8, and 10 ton models are shipped with vertical evaporator fan discharge as standard. The 12, 15, and 20 ton models are shipped horizontal discharge as standard.

CABINET

All cabinets are completely constructed of heavy gauge galvanized steel. The entire unit interior ( both evaporator and condensing section ) is insulated with 1/2" thick, 2 lb. density insulation. Service panels are equipped with lifting handles for ease of removal and handling. Duct flanges for condenser discharge, condenser intake, and evaporator discharges, are provided with the unit for field installation. Duct flange on evaporator return is incorporated into the filter frame.

COMPRESSORS

All models utilize "Scroll" type hermetic compressors. Compressors are mounted on rubber isolators to minimize vibration transmission. Internal overload protection is provided. External high pressure and low pressure cutout switches are included in each compressor control circuit. Crankcase heaters are standard on all models.

REFRIGERANT CIRCUITS

The 5 ton units have a single refrigeration circuit. The 8-20 ton units feature two independent refrigeration circuits. Each refrigeration circuit includes an adjustable thermal expansion valve (with external equalizer), liquid line filter drier, sight glass/moisture indicator, and service gauge ports.

EVAPORATOR AND CONDENSER COILS

The evaporator and condenser coils are constructed of internally enhanced copper tubes mechanically bonded to rippled aluminum plate fins. Both coils are employed in a draw-thru configuration. Large evaporator coil face area minimizes potential water blow-off.

INDOOR/OUTDOOR FANS

Forward curved, double inlet and double width centrifugal blowers are used for both evaporator and condenser air movement. Blower wheels are fabricated of galvanized steel. Blowers employ solid steel shafts, supported in permanently lubricated ball bearing. All blowers are belt driven. Variable-pitch motor sheaves allow for field adjustment of blower rpm.

ELECTRICAL/CONTROLS

All units are completely factory wired with all necessary controls. Manual reset protection is provided on both evaporator and condenser motors. A manual reset circuit is also provided on each compressor control circuit in the event of high/low pressure cutout. A 24 volt control circuit, with oversize transformer, is provided for field connection.

FILTERS

All models are shipped with 2-inch thick medium-efficiency throwaway filters factory installed. Filter rack is external to the cabinet (shipped loose).

Johnson Controls maintains a continuous product improvement policy, therefore specifications are subject to change without notice.
