Deposits of dust, lime, rust, oil and other dirt reduce the permeability of the fine cooling fins of an intercooler or oil cooler. Cooling can no longer be guaranteed with the reduced air flow and reduces the performance of the cooler until it fails completely.
To restore the original heat conduction of the heat exchangers, they must be thoroughly cleaned. Cleaning with an ultrasonic cleaner allows cleaning even between the cooling fins without mechanically damaging them.
