    CVHB 095C Trane Centravac (bench grinder)

    I fired this R-11 chiller up and it was half empty on freon. I added 800 lbs and that got me to a 33 degf evap temp. Still needs at least another 200 lbs. Everything looked normal. Chilled water-41 deg out/51 deg in
    Tower Water-76 deg in/86 deg out
    480v reading 870/920/850 amps
    Problem is the first stage started sweating like crazy. I have ran this chiller off and on sense 1990 and have never seen it. I shut it down because I was worried the terminal inlet board was sweating. Before I tear this thing down to look at the mist eliminators does someone have a suggestion?

    What's the wet bulb in the room?

    Add the gas and see if it still sweats, my guess is it doesn't.

    The plant is ventilated I did check Google and the wet bulb was 63 deg. Back in the day they were always low on charge, the old boss was stingy with the R-11. I do not remember them sweating like this-and we had (4) of them. BTW there was 5-6 psi condenser pressure. Thank you for the reply
