Chiller with HCFC 404A

I have a chiller with 3 compressor to cooled chilled water to sub-freezing temperature of -24F. While my discharged pressure is 165 psig, the saturated temperature should be 76 slightly higher than my condenser water about 60~66 F. However, I measured the actual temperature reading on my discharged piping it is almost 165F instead on 76F. Why does my discharged temperature is high?

might have to check the liquid line just out of the condenser for that reading.....the pressure will be the same as your discharge, but the state of the freon has gone from hot gas to a liquid with temperature change.
