    I saw a 250 KV underground Static line [connects two power plants] get bored into just outside the Talleyrand Generating station. The bore pierced the concrete wall of the underground splice and then...

    We have tried just about every machine on the market and for now we are standardizing around the Appion due to the fact that the bearings are not inside the acidic refrigerant flow.
    We have had...

    Trane used to have a full color book "Why Compressors fail" that was the best I have ever seen. You would just match the picture to your failed compressor and it gave you the suggested causes.

    You again missed my point which was; ask questions when you don't understand why a solution is suggested.

    Maybe someday you will meet someone who you can learn something from.

    I only pointed out your lack of full deductive reasoning and not asking questions instead of trying to assert ability [physical and mental] you do not have.

    I did not make a mistake, I never suggested that newer Lieberts used HGB unloaders. I EVEN mentioned that Lieberts can suffer from cut-off unloader leaks. Many older Carriers had HGB unloaders with...

    We have a bunch of N+1 and N+2 sites where the AC8 or Sitemaster constantly has some equipment in standby.

    For locational reasons the site operations do not want them in a rotational schedule,...

    Not putting a discharge check valve [which many/most of the older 6D/6E Carrier units used to have] and letting a compressor fail due to rapid cycling is a poor practice, much worse than a "band...

    High condensing pressures cause high condensing temps. The valve plate has a higher temp than the discharge line. At 300*F the refrigerant and oil break down to form acids whether there is moisture...

    Ntirogen requires a lot of energy to make a chemical bond, inversely it releases a lot of energy when you break the bond [many potent explosives are nitrogen based]. I have seen CO2 eat through a...

    Bristol was also the first one to try Acid-Away too and was going to recommend it until Carrier and Trane found it generated salts in the lubricant.

    CO2 in welding is a 75%-25% mixture. The CO2 being acidic cleans the steel and the 25% argon acts as a shield gas.
    I have not seen a set of Engineer's spec yet that allow CO2 inside of a brazed...

    While I have never drilled an indent into the shaft, I always super-tighten and release the set screws several times which generates a "coin mark" on the shaft and can help it not to release. The...

    If a shaft is long between the bearings and small diameter with a large wheel, it can act like a "skip rope" which will unlock the locks on the bearings. Seen it many times.
