    Yeah... hampster wheels... might move lots of conditioned air... problem is the conditioning of the air as it passes through a hampster cage... whoops...

    I was making a subtle yet sarcastic joke... I doubt folks will find a piston on refrigeration units... simply because TXV's are the way it is done. The point was to subtly poke folks to think in a bigger picture...

    Quality work at a fair price with excellent customer service!

    Yeah on a 40 year old ice milk cooler,

    They don't work that well though! Have converted a few to txv's. They are more of a fixed orifice than a piston.

    Jimmyed, Nice looking install!

    When possible, try using THHN and combine them into one conduit, looks a lot cleaner.

    Yes, it's called a capillary tube and their all the rage now among OEMs of self contained equipment because they're dirt cheap.

    I will admit I've never seen a fixed metering device on a split refrigeration system.
