  2. Large Splits Axial Condensing fan Benefits: • Split system from 20 to 90 kW • Ductable indoor unit • Auxiliar heating (elect heater or hot water coil) available • Allows ventilation, free cooling available Where to apply / typical market: • As an universal condensing unit to match with other systems (evaporator of a AHU) • For offices where duct installation is the preferred solution against chiller+FCU or multiple minisplits • Typical installations are anyplace where AHU is fitted, industry, petrol stations

  3. Large Splits Centrifugal Condensing fan Benefits: • Split system from 20 to 90 kW • Ductable indoor unit • Auxiliar heating (elect heater or hot water coil) available • Allows ventilation, free cooling available • Indoor can be installed on top of the outdoor unit (compact solution) Where to apply / typical market: • As an universal condensing unit to match with other systems (evaporator of a AHU) • Indoor Installations in technical room (to prevent from extreme outdoor temps or to install low noise kits or no outdoor inst possible) • For office buildings, supermarkets …

  4. LARGE SPLIT CENTRIFUGAL FAN – VCH Main Advantages / Features • R410A Refrigerant • Improved efficiency and reduced noise level • YKLON V3 board • Designed to service (service valves, improved accessibility) • Vertical or horizontal discharge • 50m pipe length • New options and accessories • Economizer • Return fan • Hot water coil and control (0-10V, 4 stages) Johnson Controls

  5. Stop valves Service valves Large Splits Centrifugal Condensing fan Access to components Johnson Controls

  6. Large Splits Centrifugal Condensing fan • Access to components Electrical box Motor Belt / Pulley TEV’s Sight glass Filter Drier Elec. channel Compressors Cabling Service valves Piping Johnson Controls

  7. Large Splits Centrifugal Condensing fan • Low ambient control (down to – 10°C) Actuator Control Damper Low Ambient regulation * * Not suitable for outdoor application Johnson Controls

  8. Large Splits Axial Condensing fan Main Advantages & Features Vs SOC/SOH + SICH • R410A Refrigerant • Improved efficiency • Quiet operation • Shares same indoor unit as VCH -> VIR • Long pipe run (up to 50m) • New size 20 kW • New PCB YKN2Open (JCI protocol) • New options and accessories • Soft Start Compressor for outdoor unit • LAK as option (before as standard) Johnson Controls
