This product meets the efficiency values according to ErP 2018
and many more
The compressors, fans and pumps are the only noise sources with the Explorer units. Depending on operating conditions, the noise level of the chiller can be reduced by up to 10 dB.
To do this, the maximum fan speed is restricted during operation. Furthermore, cooling capacity that is comparable with the standard version can be attained with the low-noise version due to the matching of condensers and fans.
Figure below: Restriction of fan speed - To reduce noise emission, the fan speed is reduced by approx. 30% by the use of a star-delta circuit.
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 Explorer 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.
