The temperature is rising, and you might be packing your suitcase with sun cream, but your compressor doesn’t get a summer holiday. In fact, high temperatures and humidity are exactly a compressed air systems worst nightmare if not looked after properly! Hot summer months translates to some not-so-fun challenges with regards to compressors as like the other fun things it takes along. Thus we have do’s & don’ts of compressors in summer.

Just like any appliance, compressors require regular cleaning and maintenance. Facilities rely on their compressed air system for many processes, but it is often forgotten about until it breaks down and production stops. A little preventive maintenance at the change of seasons can save you downtime and headaches later in the season.

The challenge in the hotter months is how to keep the compressor room cool when the temperatures continue to increase. Let’s get a look at how compressors are affected by heat.

• Lower Flow Rates – Higher temperature means air is less dense, so less air makes its way through the intake.
• Higher Cooling Water Temperature – The heat raises the temperature of your cooling water, forcing it to work harder.
• Increased Water Output – Warmer air can hold more water vapor. That is why having good filtration and a reliable air dryer downstream is so important to your compressed air system.
• More Draining – More water means your drains have to work harder as well.
• Reduced Throttle Regulation – by the same token, the higher intake air temperature limits the ability of the throttle valve to efficiently regulate the operating range of the compressor.

Following now we will see some of the do’s and don’ts for compressors.Ventilation: Proper ventilation helps with compressor efficiency and keeping the operating temperature down. The more obstacles you have around the compressors vents, the less effective its internal ventilation will be. For the summer, hot air coming from the machine should be routed outdoors or away from the room entirely. This can be effectively done with the use of ducts and vents.

Also, the inlet vent should be large enough to provide cool air to the compressor, and it should be placed in an area that won’t suck in warm air coming from the exhaust ducts.Filters: Increased temperatures cause changes in the ambient environment, such as the air becoming drier and dustier. Dirt and dust can form an insulating layer and build up heat on electrical components. Be sure the cabinet fan works, and to clean or replace the filters on the electrical cabinet if present.

Coolers: Dirty coolers in an air compression system can inhibit effective system cooling and lead to overheating. In the hot days of summer, consistently cleaning and maintaining the coolers is extremely important for adequate cooling. Well-maintained coolers can also help the dryers work more efficiently. To ensure proper functioning, organize a summer service to clean dust and residues from the cooling fans.

Oil: Excessive heat can drastically reduce the lifespan of the system’s oil. For the summer, check the oil on a regular schedule to ensure it’s still effective, and change it when necessary. Compressors need oil changes, especially in the summer, as excessive heat tends to kill most compressor oils. Keeping up with oil maintenance can keep the system clear of acids, moisture, and small debris.Belts and Couplings: The hotter the belts and couplings are, the faster they’ll wear out. During the hotter months, keep an eye on all the belts and couplings to ensure they’re in good shape. If they start to crack or are otherwise damaged and worn, replace them immediately. It might be a good idea to keep extras on hand just in case.

Coolants: For any compression systems that use water to cool the machine, carefully maintain the pressure, flow, quality, and temperature of the water used in the cooler. Failing to do so can lead to higher operating temperatures, which can lead to more frequent oil changes and possible overheating. The water temperature needs to be adjusted to ensure it’s cool enough for summer conditions.

DON’T operate the air compressor until you have ensured that all of the hoses and fixtures are intact and that each connection is properly connected. Leaks and loose parts can cause serious injuries when you operate the air compressor.

DON’T neglect checking of the above mentioned points while having a checkup on the compressor.

DON’T overdue any of the replacements that are needed. Like that of the oil replacement of belt, coupling replacement. In case of any cracks.
