    Freeze Pump, Freeze Protection Pump

    Good Morning,

    I'm trying to find a piping diagram for a freeze protection pump for a chilled water coil.
    I've never specified a freeze protection pump before because all the chilled water systems I've been involved with have used a water/glycol mix. Glycol is not an option for this project because the unit is being installed in a building owned by the Veteran's Administration which has a mandate against glycol due to reduced heat transfer efficiency.

    I would appreciate any help.

    Thanks,
    Eric

    Piping diagram

    This is what i've come up w/ based on a few sequences of operation that I've found...
    If anyone with a bit more knowledge could review it I'd be grateful.
