Eleven sizes with nominal cooling capacities from 40 to 162 kW.
Units integrate the latest technological innovations: ozone-friendly refrigerant R410A, scroll compressors, low-noise fans made of a composite material and auto-adaptive microprocessor control
Exceptionally quiet latest-generation Flying Bird 4 fans, made of a composite Fan motor controlled by a variable-frequency controller, to allow reduction of the fan speed, if the extra low noise option 15LS is selected. Rigid fan installation for reduced start-up noise (Carrier patent).
Low-noise, reliable scroll compressors with low vibration level. The compressor assembly is installed on an independent chassis and supported by anti-vibration mountings. Dynamic suction and discharge piping support, minimising vibration transmission (Carrier patent).
Refrigerant circuit includes all components for easy connection to a direct expansion air handling unit: filter drier, moisture sight glass, high and low pressure switch, as well as solenoid valves for pumpdown. Two independent refrigerant circuits from size 38RBS 140 onwards.
Increased energy efficiency at part load. The refrigerant circuit includes several compressors connected in parallel. At part load, around 99% of the operating time, only the compressors that are absolutely necessary operate. At these conditions the compressors operating are more energy efficient, as they use the total condenser and evaporator capacity.
Designed for year-round operation.
Electrical connections are simplified.
Exceptional endurance tests.
