RA electrical after-coolers

OMI compressed air aftercooler RA type air/air

The generously dimensioned heat exchanger and powerful electric fans allow the compressed air temperature to be reduced from 120°C to an outlet temperature 9°C higher than the ambient temperature.
Pressure losses are reduced to a minimum and the collected condensate is discharged via a condensate separator at the outlet of the heat exchanger.
