It’s been a hot summer and the warm weather is predicted to continue throughout August and into the autumn – making an overheating air compressor a very real threat in settings where it might not normally be a problem you face.
Hopefully, you followed our advice back in June to clear clogged filters and vents, test your drains and dryer dew points, and replace lubricating oil with the right viscosity for the warmer summer season.
There are other ways to tackle an overheating air compressor if you’re still having problems though – here are five of the best.
1. When windows go bad
Ventilation is good news for hot air compressors, so open windows are good too – but only if it is cooler outside than inside
Windows can also have a greenhouse effect as the sun’s rays pass through the glass and get trapped inside, so consider blacking them out if it keeps temperatures lower around your air compressor.
2. Are bigger vents better?
Bigger vents let more air in, which is better for cooling, but it is possible to go too big. If the vent is too big, this can affect the flow of air – like trying to use a vacuum cleaner with the wrong width hose – so make sure your vents are in that sweet spot in the middle.
3. Diabolic discharge
Remember the air inside your compressor is likely to be much hotter at certain stages in the process than the jet you get out of the discharge line, so if possible, test it at various points to make sure it’s not exceeding the compressor’s maximum rated internal temperature.
4. Take a break
Is your air compressor designed for continuous use? Sometimes we all need a siesta, and that goes for your machinery too. Give it a break if possible, let all its components and fluids cool to room temperature, and then you can start over on your next production run.
5. Rated limits
No matter what you do, sometimes an air compressor just isn’t right for what you’re asking from it, and especially in a heat wave, your equipment might not be rated for such high temperatures – so consider investing in an air compressor that is rated for higher ambient heat if necessary.
