Commercial Air-Cooled Condensing Units
Size Range : 1 to 20 Tons, Nominal
Starcore Refrigeration Ltd. Model Series Air Cooled and Water Cooled, Medium and Low Temperature

System Description :

Outdoor-mounted, air-cooled condensing unit suitable for on-the-ground or rooftop installation. Unit consists of a hermetic / semi hermetic reciprocating / scroll refrigeration compressor assembly, an air-cooled coil, propeller-type condenser fans with external, and an electrical control console.

Quality Assurance :

  • Unit shall be rated in accordance with ARI Standard 360-2000.

  • Unit construction shall comply with ANSI/ASHRAE 15 safety code latest revision and comply with NEC.

  • Unit shall be constructed in accordance with UL 1995 standard and shall carry the UL and UL, Canada label.

  • Unit cabinet shall be capable of withstanding 500-hour salt spray exposure per ASTM B117 (scribed specimen).

  • Air-cooled condenser coils for hermetic compressor units shall be leak tested at 150 psig, and pressure tested at 350 psig.

Equipment
 

General :

Factory-assembled, single piece, air-cooled condensing unit with factory wiring, piping, controls, compressor, holding charge, and special features required prior to field start-up.

Unit Cabinet :

  • Unit cabinet constructed of galvanized steel, bonderized and coated with a epoxy non corrosive powder coat paint of 50 to 100 micron thickness pre painted baked enamel finish.

  • A heavy-gauge roll-formed perimeter base rail with forklift slots and lifting holes shall be provided to facilitate rigging.

Fans :

  • External Rotor Condenser fans direct driven, propeller-type, discharging air vertically upward.

  • Fan blades dynamically balanced.

  • Condenser fan discharge openings with PVC-coated steel wire safety guards.

  • Condenser fan motor IP55 degree protection.

Compressor :

  • Compressor hermetic / semi hermetically sealed reciprocating or scroll type.

  • Compressor mounted on anti vibration mounts.

  • Compressors with overload protection.

  • Compressors equipped with a crankcase heater.

  • Compressor with safety control like internal high discharge temperature protection.

Condenser Coil / Shell and Tube Condenser :

  • Condenser coil shall be air-cooled and circuited for integral sub cooler.

  • Standard condenser coils are with internally enhanced copper tubes and aluminum fins. Coils are furnace brazed design. Condenser coils are leak tested to 150 psig; pressure tested to 350 psig, and qualified to UL 199 burst test at 1980 psig.

  • All tubes used are internally enhanced and in case of water cooled condensers are externally finned to increase the heat transfer area.

  • All shell and tube condensers come with IS 1239 shell tube and flanges as per DIN standards

Refrigeration Components :

Refrigeration circuit components include liquid line service valve, suction line service valve, oil separators, accumulators, liquid line solenoid valves, catchall driers, a full charge of compressor oil, and shipped with Nitrogen inside to ensure no leaks during shipment.

Controls and Safeties :

1. Minimum control functions include

  • Control wire terminal blocks.

  • Compressor lockout on auto-reset safety until reset from microprocessor controlled thermostat.

2. Minimum safety devices which are equipped with automatic reset include

  • High discharge pressure cutout.

  • Low pressure cutout.

  • Oil safety switches in case of semi hermetic compressors.

Electrical Requirements :

  • Nominal unit electrical characteristics are 400v 3-ph, 50 Hz. The unit is capable of satisfactory operation within voltage limits of 380v to 420v.

  • Unit electrical power is a single-point connection.

  • Unit control circuit is 220 Volts.

Special Features (OPTIONAL) :

  • Low-Ambient Temperature Control : A low-ambient temperature control can be available as a factory-installed option or as a field-installed accessory. This low-ambient control will regulate speed of the condenser-fan motors in response to the saturated condensing temperature of the unit. The control will maintain correct condensing pressure at outdoor temperatures down to -20 DegC.

  • Optional Condenser Coil Materials : Condenser Coil Protective Coating Blue fin coils and Marine water Condensers available on special request.

  • Unit-Mounted, Non-Fused Disconnect Switch in case of emergency:

  • Switch is factory-installed and externally mounted.

  • Thermostat Controls : Programmable multi-stage controller with features that can be user defined, integrated to a compatible PC system with software to view and control operating parameters and remotely monitored, a Optional supply accessory.
