Efficiency challenging the future: ErP 2018 ready

The European Regulation EU 2016/2281, known as ErP 2018, sets the new SEPR parameters for assessing the energy efficiency of chillers. The entire CyberCool 2 range complies with the limits required by ErP 2018. 


  • E.E.R.: Energy Efficiency Ratio
    Chiller efficiency at a certain condition.


  • E.S.E.E.R.: European Seasonal Energy Efficiency Ratio
    Seasonal efficiency of a chiller for comfort: ambient air from 25 to 35°C


  • S.E.P.R.: Seasonal Energy Performance Ratio
    Evaluates the load and temperature variations during the year,
    relative to the chiller's electricity consumption.
