2 STANDARD INCLUSIONS: Fully wired electrical panel - includes space for additional electrical equipment Rotary isolator switch Hydrophilic Blue aluminium fins and high efficiency inner grooved tube condensers Axial-flow, external rotor motors - vertical air discharge Powder coated frame for protection against the elements in exposed locations Liquid receiver Liquid line drier Liquid line sight glass Oil separator Suction line accumulator - insulated suction line Dual Pressure Switch HP Fan control to cycle condenser fan at low ambient Flexible high pressure control hoses to pressure switches Schneider switchgear as standard Crankcase heater OPTIONAL EXTRAS: Fan speed controller Suction line filter Additional schrader connections Brazed plate heat exchanger for heat reclaim applications Brazed plate heat exchanger for liquid chiller applications APPLICATIONS: The 500 Fusion Series condensing units are well suited to applications where a wide operating envelope is required at higher ambient temperatures. With integral economiser, the compressor scrolls and oil is cooled resulting in the compressors ability to operate at higher ambient temperature without overheating. INTERNAL SONIC LINER The compressor compartment is internally lined with sound absorbing foam sonic wave liner to shield and reduce noise generated by the compressor from transferring outwards. HYDROPHILIC BLUE FIN CONDENSERS All Altitude condensing units feature treated aluminium blue fins with hydrophilic qualities. This treatment means the condenser fins are protected against corrosive elements and they have a longer lifespan in aggressive surroundings such as sea spray and airborne chemical environments.

In addition: Provides scroll and oil cooling while delivering subcooled liquid refrigerant to the evaporator Refrigerant feed for compressor cooling is precisely metered using an electronic expansion valve digitally controlled by on-board CoreSense electronics based on discharge gas temperatures Discharge gas temperatures are kept within acceptable operating limits even under low temperature operations Serviceability in the Field Copeland Scroll Fusion s horizontal cast iron body allows for complete field serviceability. Standard field tools can be utilized to service the compressor and it is easier to service than traditional semi-hermetic piston compressors due to the fewer moving parts associated with the scroll design.

Vapor injection subcools the main liquid line and cools the compressor oil by the economizer s plate heat exchanger. This underscores the importance of insulating the liquid line from the economizer to the evaporator. The subcooled liquid will increase the capacity of the expansion valve; therefore, users must follow the manufacturers liquid line temperature correction factors for proper selection of expansion valves. Pumpdown Cycle Copeland Scroll Fusion compressors have an inherently superior liquid handling capability so a pumpdown at each thermostat cycle is not recommended. Copeland Scroll Fusion compressors are fitted with spring loaded low-leak check valves. Therefore, an external check valve is not necessary. When a pumpdown cycle finishes, the compressor will stop and will contain a very large volume of high pressure gas in the top cap area, which will leak back to suction and cause a significant rise that could reset the low pressure switch. The control circuit should not allow the compressor to restart on pressure. Restart should only occur when the thermostat closes. Legend - Compressor Dimensions 500 EX Fusion Compressor Series 5
