Two-Stage After cooler Cooling Systems
The two-stage after cooler, currently offered for some gas engines, is intended to provide high temperature heat recovery for Electric Power Generation (EPG) applications and Reduce overall radiator sizing for Gas Compression applications. There are two coolant stages on
the two-stage after cooler; the first stage uses high temperature coolant to cool the charge air to an intermediate temperature and the second stage cools the air down to
engine rating requirements. The two stages after cooler can allow much higher coolant inlet pressure to both stages than the single stage after cooler. There are various cooling systems available for use with the two-stage after cooler. These are offered in the Gas Engine Price List. Contact Caterpillar for more details on these cooling systems
