16 17-Dec-15 Customer benefits 1. Inverter outdoors (ERX or VRV) 2. Pair (ERX) and multi applications (VRV) 3. Extended control systems possible : control on evaporating temperature control on air temperature (suction / discharge / room temperature) Compared to Chillers : 1.Same small temperature gradient and control possibilities 2.No hydraulic components 3.Better price setting 6.
