THESE AIR OIL COOLERS ARE USED WHERE THE TEMPERATURE TO BE MAINTAINED IS NOT VERY PRECISE. These units are equipped with a Fin & tube heat exchanger & Axial Fan. The air is passed over the heat exchanger
external surface area and oil flows inside the tube from the bleed line of the power pack. Here the temperature of the oil depends upon the ambient temperature. These units are equipped with a digital
temperature indicator cum controller to cut off the fan when the set temperature is attained .
