• State-of-the-art concept - Reduced size and weight make these units ideal for today’s lightweight building structures. - Rugged design of critical components. e.g. motor supports, suction/discharge piping etc. - Powder-painted sheet metal, especially suitable for outdoor use (light-grey colour RAL 7035).
• Exceptional endurance tests - Corrosion resistance tests for polyester powder painted galvanized sheet metal parts in salt mist. - Accelerated ageing test on components that are submitted to continuous operation: compressor piping, fan supports. - Low vibration design. - Transport simulation test.

These new rooftop units integrate the latest technological innovations: - state-of-the-art scroll compressor technology, - low-noise fans made of composite material, - auto-adaptive Pro-Dialog+ microprocessor control - Variable air volume supply fan optimizing energy consumption at full load and part load

• Excellent full and part-load efficiencies achieved with multiple scroll compressors and indoor coils with dual refrigerant circuits. The refrigerant circuits are both electrically and mechanically independent, to provide standby capability should one circuit require service. Totally enclosed outdoor fan motors are designed for many years of trouble-free operation.
•  Increased energy efficiency at part load, around 99% of the operating time. Only compressors that are absolutely necessary operate.
