Greg Jolley – Michelin Tire, – Spartanburg, SC

US3 (Spartanburg) is still very pleased with the Case Controls. I do not have history on energy savings. Our consumption has steadily gone up over the last few years with equipment modifications, higher production, less attention to leaks, etc… I can say that we are presently using about 3.5 of 4 compressors which means they run at MMA a lot of the time. Prior to Case all of our compressors had a MMA setpoint of 53 amps. But with Case I have seen MMA as low as 47 to 48 amps (according to the condition of the machine) in the cooler months. So it would be safe to say that for at least 6 months out of 12 we save 5 amps at 4160 vac 3 phase on the 3 Case Controlled machines. –> 3 mach x 5 amps x 4160 vac x 1.73 = 108 kw, –>108 kw x 24 hr x $.05/kwh x 30 days = $3,888 / month.

I am very pleased to say the install is complete and everything is going great. The system is operating exactly as you described it would. My guy’s are real excited about the system and the way it is running. We just started Air Master this morning and already I am seeing a more stable PSI in the plant than before.

I wanted to take a minute to thank for all you help getting the project completed. I am not the most knowledgeable person when it comes to air compressors and controls. You did a great job of explaining everything to me in a way that I could understand. It was a pleasure working with you and your company. I also want to thank Air Relief. They too are an outstanding outfit and have great people representing them in the field.

Reid Sasaki – AES Hawaii, Inc., – Kapolei, HI

On December 19th, 2002, all three of AES Hawaii’s Ingersoll-Rand Centac plant compressors failed to start after a unit trip. Upon further investigation, it was determined that the MP3 control boards in all three compressors had been destroyed due to a voltage disturbance. Although we were able to replace one of the three MP3 control boards with a spare, it was imperative to repair the remaining compressors as soon as possible. Due to the obsolescence and unavailability of the MP3 control boards and timing of the event during the holiday season, AES Hawaii was in quite a predicament.
