  1. Air-cooled small chillers 33kW (9,4TR), 80kW (22,7TR), 110kW (31,3TR) Confidential Property of Schneider Electric | Page 1

  2. Aquaflair Applications Critical Environments • Data Centers • Computer Centers • LAN Rooms • Laboratories Industrial processes • Process Cooling / industrial • Transportation • Food and Beverage • Healthcare • Energy Confidential Property of Schneider Electric |

  3. Technical Vs Comfort chillers AvailableModifications are necessaryComplete design isnecessary Confidential Property of Schneider Electric |

  4. Small and mid chillers 33kW (9,4 TR) 80kW (22,7 TR) 110kW (31,3 TR) Air-cooled small and mid chillers kW LRAC180A ERAC0921A ISAC1221A Air-cooled chillers Performance data refer to nominalconditions: water inlet/outlet temperature 12/7°C; outdoor ambient temperature 35°C; 0% glycol

  5. ISAC1221A VSD compressors Scroll compressors • One inverter driven scroll compressor + one fixed speed scroll compressor • Environmentally friendly R410A • Single passage plate heat exchanger • Finned tube condensing coils • Quiet noise version • Electronic Expansion Valve • AC/EC fans • Integrated soft start & PFCs • High / Low ambient temperature operation (+ 50 down to -20°C) Main features Confidential Property of Schneider Electric |

  6. High water temperatures LRAC / ERAC / ISAC Operationat high water temperature and wide delta T LRAC/ERAC/ISAC units can efficiently operate at high water temperatures and wide delta T High water temperatures & wide deltaT are mandatory to comply with ASHRAE standards improve OPEX: • Pump power saving • Less power consumption on fan side allow CAPEX reduction • Saving on hydraulic infrastructure • Reduced pressure drops ISAC1221A – Mumbai 100kW, delta T = 5°C Annualenergyconsumption @ 7/12°C is 216000 kWh Confidential Property of Schneider Electric |
