IEV & XEV

IEV & XEV represent Dixell solution for stepper electronic expansion valves management. XEV20D (combined with iPro controllers), IEV22/24D (stand-alone functioning or combined with IC200 evo controllers) allow the best superheat regulation of the unit. In this way the maximum performance of the unit is guaranteed during every weather operating condition, thus improving energy saving.
