Engine power definition is according to ISO 3046-1 and ISO 8528-1. However the engine ratings are valid for the following reference conditions:
Air inlet temperature                                          max.  + 38°C
Air inlet temperature                                          min.  + 5 °C
Heat dissipation.                                                + 25°C
Charge air low temp. cooling  water inlet temp.    max.  +42 °C
Site altitude above sea level                               max.   258 m
relative humidity                                               60%


Charge air cooler heat dissipation will vary with water flowrate and inlet temp., these data to be calc. after receipt of final process data

Specific energy consumption is according to ISO 3046-1 and is given at full load(MCR), running on NATURAL GAS with a lower heating value of 36.0 MJ/m3n and two engine-driven pumps.
