    Who's using an MBK6?

    How are the rest you faring with your own MBK 6?

    I just filled my MBK 6 from REHVAC with dry co2 for the first time for my next install.

    Very convenient and light.

    I recommend it highly.

    Just click on the pdf for filling instructions.

    Been thinking about either the MBK6 or just a small 2.5 or 5# tank, just bought the adapter to use my nitro regulator on Co2 tanks.

    Are you using it as a purge gas and to pressure test new systems hvaclover?

    I think johnstone has it on sale for like 179.00 or something like that right now.

    That MBK-6 looks usefull, except, I was doing some reading on the web the other night. It was an article about leak testing from some manufacture or product company can't remember for sure, but they made a serious statement against using co2 for pressure/leak testing. They didn't say why...... just said "don't ever do it"!
    Any one know why ?

    Yes I am using it to pressure test and as a braze purge.

    co2 is not an inert gas. combined with moisture it makes carbonic acid. Not for use in refrigeration systems. Looks like it's made for clearing condensate drains. Hope Installers aren't using it to purge systems but from these posts it sounds like they are. You might as well use compressed air.

    It does have an adaptor available for nitrogen

    It's not compressed air. If you'd study more before accusing you'd know that.
    There are plenty of threads on BONE DRY CO2.

    It is not soda fountain CO like you buy from your supplier, it is pure..processed to the the degree it is dry and safe to use ...FYI...back in the day CO2 was the only braze purge around....I buy mine in 65# tanks.

    Question,

    Even if the CO2 is BONE DRY, won't you still get acid if there is any moisture in the system ?
    Do you evac first to 500 microns to be sure of no moisture before adding the CO2 ?

    Not trying to be a pain, just really trying to understand gas cost vs. extra time ( if needed ) of BD CO2 vs. N2. I know the N2 cost more than CO2 but will you save enough to pay for having second HP cylinder for CO2 ? Maybe you don't use N2 at all, so only one bottle ?
