Thread: New coil

  1. #1

    New coil

    I have an inquiry I hope you can help me with. If a new coil is ordered from one of the HVAC companies, should the coil be pressurized with Nitrogen? I could understand the tube ends being plugged to avoid entry of dirt, but if the coil isn't filled with Nitrogen, would there really be a problem with corrosion?

    A new coil should be charged with some inert gas to prevent having moisture in it from the atmosphere.

    Most replacement coils are shipped with a holding charge of Nitrogen these days, to prevent air and noncondensibles for entering the coil, and to verify the coil does not leak prior to installation.
