Technical data VZH line up by configuration and modulation range Hybrid Tandems Maximum capacity: 100 RPS ARI Minimum capacity: 15 RPS (VZH 028-044) & 25RPS (VZH 088-170) 7,2°C / 35°C / 11,1K/ 8,3K (Part load) VZH 4-7TR have built-in Intermediate Discharge Valves (IDVs). IDVs adapt the effort of the motor and its energy consumption to the varying load thus improving the seasonal efficiency of air conditioning systems. For more information see the video: VZH 13-26TR models are optimized for two pressure ratios to deliver enhanced efficiency in diverse applications. Evaporating temperature (°C)...
