    R1234ze

    Has anyone got much experience on Chiller with R1234ze?
    Its an A2L so I'll need new recovery units, vac pumps etc.

    Whats the low down with repairing/brazing a leak on a chiller with R1234ze?

    Check manufacturer information, your equipment might already be compatible.

    Naval has a similar document. I don’t think you’d need a new vacuum pump since there wouldn’t be much refrigerant when your pulling a vacuum. JB does sell a spark proof vacuum pump though.

    Appion states that their vacuum pump works with A2L refrigerants because of the cooling fans. They prevent accumulation of refrigerant.

    I imagine ventilation would be what’s most important when working with these refrigerant.

    Just a few thoughts.
