    Liquid Float Drainers use in Hot Gas Defrost



    Hello everyone,

    What is everyone's thoughts on Liquid Float Drainers and their use in Hot Gas Defrost? Do they work well? What issues should one look out for?

    Any insight is much appreciated as I'm a newbie in the industrial refrigeration arena.

    Regards

    Hi Redbos.
    welcome to the forum.
    Firstly, hot gas is more like cool gas by the time it reachs the evaporator, with suction pressure regulation etc., the evap becomes a big condenser, so draining excess liquid is necessary. So long as drain valve is sized correctly no problems, oil draining will happen at same time, the oil can clogg up the float and orifice though, and not drain excess liquid. So when system changes over, it can create a flood back.

    So it sounds like if they are installed correctly, they should work well.

    From an energy standpoint, how do Liquid Float Drainers stack up to other methods of defrost?

    the WITT have high pressure float regulators, and are the "HR".

    Definitely liquid drainers are better than back pressure regulators, because they drain the liquid and don't pass the gas. Blow by gas will reduce plant efficiency. However, liquid drainers are more expensive than BPRs.
