Intercooler / Charge Air Cooler

The intercooler is air to air type and has a large cooling fan capacity. The intercooler life and performance
depends on the intake air condition greatly. Fouled air pollutes and clogs the air fins of intercoofer. As a
result of this, the engine output is decreased and engine malfunction is occurred. So you always check
whether the intake air systems like air filter element are worn or polluted.
• Cleaning
In order to maintain the heat transfer efficiency of the intercooler, it is necessary to clean it at regular
intervals.
Cleaning of intercooler fins : Every 600 hours for normal site conditions.
