Six simple ways to improve your compressed air system
By Ron Marshall Compressed air is one of the most expensive ways to supply energy to facility tools and equipment. This is due to the inherent inefficiencies in the process of compressing air — the biggest product is heat and the secondary output is compressed air. While this is disappointing, there are still things that […]
Why is compressor control important?
When controlling screw compressors, the goal is to try to keep all the running compressors fully loaded except one.

Compressed air fail: Ventilation design
A plastics manufacturer was having constant trouble with his desiccant air dryers. No matter what he did, they would constantly set off dewpoint alarms, which was very annoying. He called in a compressed air auditor to have a look. The auditor shot temperatures and found that the discharge of the compressors was too hot. Outputs […]
Compressed air fail: A modulation nightmare
John, the maintenance manager of a wood products company, was very proud of his Number 3 compressor. It has been operating for years, racking up more than 200,000 run hours — and was so trouble free, it was almost scary.
