As we all know, air compressors can be divided into fixed and mobile series.

For the fixed series, the after cooling system is divided into two parts which respectively cool the hot oil and the compressed air, so the temperature of the compressed air is relatively low.

For the diesel portable air compressors, as it is generally used for field construction, the requirement of the temperature for the compressed air is not strict, so the after cooling system of the standard model diesel portable air compressors is only used to cool the hot oil, there is no cooling effect on the hot compressed air, and the temperature is about 80 degrees Celsius, which is relatively high.

If our customer needs to cool the hot air, what should we do? There are two solutions that can be solved. One solution is to add a built-in radiator, which is specially used to cool the hot air, this solution needs to be reset the internal structure of the air compressor, which will increases the procurement cost and delivery time for the customer; The other one is to add an external aftercooler, compared with the first solution, the operation is relatively simple, and for the customer, the procurement cost is reduced, the delivery time is relatively short.

Therefore, adding an external aftercooler is the most effective solution.

If you have a similar problem in the future. do you know how to choose now?
