MECHANICAL SPECIFICATIONS

General

All units are factory assembled, piped, internally wired and fully charged with R-22. They are also tested and checked under a strict quality control system in the factory. All units are designed for outdoor rooftop or ground level installation. Exterior surfaces of all units are phosphatized, zinc-coated steel with acrylic resin primer and ivory white baked enamel finish.

Condenser Coils

Unnecessary power input due to higher discharge pressure is avoided by high performance designs of cross-finned coils. Condenser coils are made of 9.52mm OD, 0.35mm thick seamless copper tubes mechanically bonded to 0.12mm thick aluminium plate fins. Each coil is factory pressure and leak tested at 3.3MPa.

Refrigeration Controls

Refrigeration controls include condenser fan, evaporator fan and compressor contactor. Each circuit of the unit has a separate set of refrigeration controls. PR, PRH,PRH-L-15,20 units have two independent circuits.

Evaporator Fans

Belt-drive, forward curved, centrifugal type fans made of galvanized steel are used to deliver an accurate airflow at low noise level.

Compressors

All units have high efficiency type hermetic line starting compressors. Compressors are equipped with thermal overload protector, overcurrent relay and high pressure protection controls. Crankcase heaters are standard .

Condenser Fan

This direct-drive propeller fan is dynamically balanced, to ensure smooth airflow. A weather- proof three-phase squirrel cage induction motor is used to drive the condenser fan.

Evaporator Coils

Highly efficient cross-finned coils are applied to provide a larger cooling capacity with low air speed on the coil. Coils are made of 9.52mm OD and 0.35mm thick seamless copper tubing mechanically bonded to 0.12mm thick aluminium fins and are factory leak tested at a pressure of 3.3MPa. They are provided with strainers attached to the capillary tubes to further ensure a clean system.
