Olive Street Fort Collins CO 80524 12/13/2014 104773 Make repairs Chilled water make up tank is low. Notes added by tech Tom S on 10/222014 0001 I1•jPPIler4 Check for leaks in the chilled water system. Checked the chiller for possible water leak in the evaporator. Checked building piping and pumps. Found an air bleed that was oV 4 damaged and was leaking and a small leak at the bottom o the header of the chilled water coil. Replaced two of the chilled water air bleeds and checked system. I PV 4 Notes added by Mike E. 10242014 Rob reported that they had added 15 gallons of glycol mix to the make up tank in the past two days. When 1 arrived the make-up tank level was half. So of that 15 gallons added, 12 to 13 gallons had been pumped into the system in 2 days. I checked the evaporator bundle to see if there was any water in it and found it had refrigerant that smelled clean. I looked for leaks all over the system as Tom had done before me. The only thing I found was the expansion or compression tank was almost water logged. This is an air to water tank with a gage glass. It would appear the upper valve of the gage glass has allowed the air to escape from the tank. I suggested they replace this tank with a bladder type tank. The tank volume is about 10 to 12 gallons, about the amount that of glycol mix that has been added. The chilled water coil is leaking at the header again, same place as this past spring. But there is only a small amount of water on the floor. No other leaks were visible. Will follow up with a bid for the tank replacement. Notes added by tech Tom S on 10272014 Was called back, the system was still loosing volume. Found the air tank for expansion had lost its air pocket and had water logged. Will get a price for a bladder style tank for repair and waft for approval. 0000648 Latch # 5.50 Labor 103.00 566.50
