I would like to pick the brains of you experienced individuals out there.
We are in the process of pulling a vacuum on our machine. The machine is a 2550 ton York Turbomaster.
The instrument we are using to check the wet bulb is a Supco VG60. We have been running our vacuum pump for a couple of days now, yet the indicator shows only 100-1500 microns. It would not go any lower than that. I was hoping for at least 700 microns. Any suggestions? Is the Supco gauge reliable. What is the ideal dry system? Any recomandations on alternate micron gauges?
