Choosing Between an Air-cooled or Water-cooled Compressor

By: Neil Mehltretter

For larger industrial plants, a common consideration when selecting a rotary screw compressor is whether to go with an air-cooled or a water-cooled version. Both designs certainly have their advantages and naturally their disadvantages. In general, the vast majority of rotary screw installations are air-cooled. Air-cooled rotary screw compressors are typically more readily available, and will require less overall installation costs. However, there are some applications where water-cooled compressors could be advantageous. The best way to approach this decision is to consider your compressed air system installation. Here are four questions to answer when deciding whether to go air-cooled or water-cooled. Continue reading “Choosing Between an Air-cooled or Water-cooled Compressor”

The Trouble with Modulating Compressors

By: Michael Camber

Many plants are still running modulating compressors. For many decades, they were the go-to design choice for compressed air systems. Now they’ve mainly been relegated to warming the bench, mostly due to the rise of variable frequency drive (VFD) compressors. While still numerous, they pose problems—especially in the areas of controls and efficiency. If you have multiple modulation control units in your plant, you just might have the makings of an energy savings jackpot. Continue reading “The Trouble with Modulating Compressors”

Zen and the Art of Compressor Maintenance

By: Werner Rauer

I’ve never understood the reluctance to take care of routine compressor maintenance. They’ll say compressed air is absolutely critical for their plant and that their processes can’t function without it. But, in the next breath admit they don’t regularly change the oil or check the air filters on their compressor. Truthfully, regular care and maintenance is one of the best ways to bring a little Zen to your compressed air system. It can reduce unscheduled downtime and keep your system running as efficiently as possible. Here are five tips on what to consider when putting together a maintenance plan for your plant.
