HRT Knowledge

The cooler is a very important part of the screw air compressor. The main function is to cool the lubricating oil of air compressor and the compressed air. If it’s blocked, then the temperature will go up. A main cause of the air compressor failure at high temperature is the blockage of the cooler.

So what are the causes of the blockage of the cooler?

Dust is the most common cause of air compressor cooler blockage. It usually happens when there is no dust cleaning for air compressor cooler for a long time. On the other hand is the dusty environment around the air compressor.

If the place of air compressor station is harsh, and it is not well protected, blockage also occurs. For example, things as the broken thread of textile industry, sawdust of furniture factory, iron filings of steel works float in the air and stick to the cooler will lead to blockage.

Some users bought bad-quality air compressor lubricants out of their bargin-loving heart. Or if the air compressor runs in a high temperature for a long time, the inside of the cooler will form carbon and cause blockage. Reducing the amount of lubricating oil flowing through the radiator, results in poor heat dissipation.

There are three main reasons for the blockage of air compressor cooler, and we’d like to inform you to prevent the clogging of the cooler, ensure the normal operation of the cooler and improve the production efficiency. At the same time, it also requires users to clean the coolers daily, do the maintenance work in time, and find professional after-sales staff to deal with the problem.
