I have a customer that is a resort with a small 9 rack system with 7 medium temp 2.5 horse compressors and to low temp compressors. One of the compressors is on its way out become very loud and showing symptoms a possilbe burnout to come acid test are clean right now, but I am trying to educate the customer about the dangers of burnouts in a rack system, and the benefits of changing the compressor now to save them the money. They are very in charge types and I need some literature to back me before our meeting can anyone help, with literature that can illustrate the cost of waiting for this compressor to burn out and having to clean the entire system up.
