140R1723Q0060/0002 compressors. The current compressors:

- Each have an individual receiver tank.

- Are water cooled by the plant service water system. NOTE: Chlorinated water is used to prevent the build-up of algae in the cooling system.

- Are equipped with a refrigerated air dryer on the discharge air supply.

The station service air compressors currently in use at Hungry Horse Field Office normally run with one compressor operating on the LEAD

Pressure Setting and the other compressor operating on the LAG Pressure Setting.

- The compressor operating in the LEAD Pressure

Setting is set to automatically maintain station service air pressure at 98 PSIG.

- The compressor operating in the LAG Pressure

Setting is set to start if the station service air pressure drops to 88 PSIG.

Normal compressed air for the generator brakes of the current system is supplied by utilizing a

3/4-inch tie line between Station Service Air

Receiver No. 2 and the Brake Air Receiver. This supply is provided with two manually operated isolation valves and a check valve to prevent backflow of brake air into the station service air system. The current compressors:

- Are nominally rated at 500 cfm (at 110 PSI), with a maximum working pressure of 150 PSI.

- Are located in a controlled indoor atmosphere.

- Are Atlas Copco Rotary screw compressor
