High Performance Components High SEER Special inverter fan (option) pCO1 control and PGD user interface 3 pump option Energy saving in partial load True dual circuit evaporator Optimized heat transfer coefficient 800 mm, 6 poles, axial fans Blue fin coil as standard on HP models 360° accessible compressor box for maintenance

Oustanding Strength Points  Units with R410A refrigerant (it will be the real replacement of R22). As near azeotropic mixture it behaves like a homogeneous substance (reduced service problems in case of leakage or re-charge) with negligible temperature glide. Refrigerant with superior thermo-dynamical proprieties compared to R22 and R407C, it allows to have more efficiency or compact and lighter systems and larger operating limits (T ambient = -15 °C in heating mode).  2 independant refrigerant circuits with 2 scroll compressors for each circuit.  Bi-flow electronic expansion devices on...

Specifications (continued) Compressors ➜ Evaporator antifreeze protection. Each unit is equipped with 4 hermetic scroll compressors arranged in tandem configuration per refrigerant circuit. ➜ Heat pump defrost control for automatic operation. The compressors are fitted with an electronic control device which ensures protection of compressors against : - overheating and overloading, ➜ Management of the electronic expansion valves by means of EXV controller allowing optimized functions : cooling, heating, start-up and defrost. - reversal rotation and phase loss. ➜ Management of external...

Control : ^ HP and LP transducers (two for each circuit). ^ Evaporator water inlet température sensor. ^ Evaporator water outlet temperature sensor (with an antifreeze function). ^ Suction temperature sensor for EXV control. ^ Ambient air temperature sensor. ^ Coil temperature sensors. ^ Heat recovery condenser temperature sensor (AQVR only). Conformity with standards The following applies to all the sizes and versions of AQVL/AQVH/AQVR units : 3 Machine Directive : 2006/42/EC 3 Low Voltage Directive : 2006/95/EC 3 Electromagnetic Compatibility Directive : 2004/108/EC 3 Pressure Equipment...

All hydro options are supplied fitted inside the unit.
