  2. RANGE DESCRIPTION

  3. Range description 2 Families Close Control Unit – INNOV@ Telecom Unit – @DNOVA Capacity kW

  4. Range description 4 ranges DX from 6 to 20kW INNOV@ CENTRIFUGAL Medium size : DM Chilled water from 8 to 22kW INNOV@ECFAN Chilled water from 8 to 236kW High size : DH INNOV@ECFAN DX from 20 to 120kW DX from 7 to 70kW INNOV@ENERGY DX from 2.5 to 26kW @DNOVA

  5. INNOV@ Codification Codification : D H x x x 0000 INNOV@CENTRIFUGAL & INNOV@ECFAN Medium size DM INNOV@ECFAN High size DH IN INNOV@ENERGY TH @DNOVA

  6. INNOV@ Operating mode Codification : D H A x x 0000 A Air cooledwithremote condenser W Water cooled with remote dry-cooler Z Water cooled for city tap water

  7. INNOV@ Operating mode Codification : D H C x x 0000 C Chilled water Dual Cooling • Air cooledwithremote condenser more • chilled water coil D

  8. INNOV@ Operating mode Codification : D H K x x 0000 • Water cooled with remote dry-cooler • more • chilledwater coil K Dual Cooling Dual Cooling • Water cooled for city tap water • more • chilled water coil Q

  9. INNOV@ Operating mode Codification : D H F x x 0000 • Water cooled with remote dry-cooler • And indirect free-cooling F

  10. Return air INNOV@ Operating mode Indirect Free-cooling Onlyavailable for unit water-cooled with dry-cooler Itisnot and option thisis a type of unit Dry Cooler

  11. INNOV@ airflowconfiguations Codification : D H x D x 0000 Downflow discharge D Upflow discharge U Displacement X

  12. INNOV@ Fans Codification : D H x x R 0000 Centrifugale For capacity from 6kW to 22kW C High pressure fan as an option Psd =100 à 250 Pa Radial plug fan For capacity from 6kW to 236W R Plug Fan with EC motor (std) Aesp =140 à 560 Pa 600mm for DM 795 or 950mm for DH

  13. INNOV@ Codification Codification : D H A D R 0 5 9 2 • DH = INNOV@ A = Air cooledwithremote condenser • D = Downflow discharge • R = Radial plug fan with EC motor • Capacity kW in this case 59kW • Number of compressors/circuits in this case 2 comp/2 circuits • 0 or 1 = 1 compressor / 1 ref. circuit or chilled water unit • 2 = 2 compressors/2 circuits • 4 = 4 compressors/2 circuits • One exception 0205 whichmean 20.5kW withonly 1 compressor/1 circuit

  14. INNOV@ General features • Refrigerant: R407c et R410a • Refrigerant components • Scroll compressor • Plate heatexchanger AISI304 • Filterwithmolecularsieve and activated alumina. • Sight glass withhumidity indication. • Thermostatic valve with MOP function and externalequalization. • Liquidreceiver • HP pressostat withmanual reset • LP pressostat withautomatic reset • Schrader valves for maintenance and/or Control. • Hydrophiliccoiltreatment: • Allows film condensation in dehumidification • Process • No water dragging, especially in downflow units

  15. RANGE DESCRIPTIONDM • 6 - 21kW direct expansion • 8 - 23kW chilled water
