Specifications include, but are not limited to: A. Vibration Analysis 1. All Vibration Analysis testing should be provided as requested by the University. After completion of each test, the vendor shall interpret the results and provide a written report to the University including any corrective action(s) necessary. 2. The vibration signature of each chiller shall be compare with the manufacturer's data on similar make, type, model, and amount of run type through a database. A recommendation will be made in order to minimize risk of chiller failure. 3. The vibration analysis must be performed by a certified vibration analysis agency. The vibration analysis report on chillers should compare actual readings to the most current published ASHRAE recommendations and be based on: Amplitude - measure of severity in terms of inches per second of velocity (IPS) or gravity of acceleration. Modulation - shown as a group of spikes around a specific frequency. Harmonic Content - vibrations occurring at 2x, 3x, etc. The frequency of interest. Orientation - vertical, horizontal, and axial. B. Oil Analysis 1. Oil Analysis to check the internal integrity of the refrigeration equipment must be performed as requested by the University. The University must be advised of any dynamic or static parameters that may cause equipment problems. 2. An oil sample must be taken and analyzed in a certified laboratory as proven to and approved by the University. The oil analysis should test for wear metals, total acid number and debris in the oil, moisture content, etc. A comprehensive report must be given as per below: Water ppm Acid Number mg KOH/g Chloride ppm Fluoride ppm Ion Activity mmhos Aluminum ppm Copper ppm Chromium ppm Iron ppm Nickel ppm Lead ppm Tin ppm Zinc ppm Phosphorus ppm Oil Type ppm
