    Awesome. Thanks! Starting to see more. Co2 systems come out of the woodwork in my neck’0’thewoods as well. I have yet to have to charge though. Is that just a regular drum adapter?

    Thanks for sharing. Always good to see work in the field.
    Safety principles should be an underlying element whenever working, and definitely highlighted in your presentations. Some have been touched on by others, like tethering the hose and protection for the public/customers. And where are the technician's PPE? Seems like safety glasses are an optional accessory on many Market Refrigeration Specialists.

    I agree with Mike Wolins. C02 is the future of supermarket refrigeration (even though its an old school refrigerant). But its different than the HFC's. The pressures are much higher. A transcritical rack runs a head pressure of over 1000 psig. So safety measures should be taken seriously and explained. There's a lack of professionalism in our field. But it needs to start with the veteran techs. It's no longer about picking up experience in the field. Tech schooling and training is a must. There's more to charging a C02 rack, than just connecting a hose to a CO2 cylinder and adding it in as liquid. For safety there are set temperatures you want to achieve. And of course your Personal Protection Equipment (PPE).

    I don’t know if you will see this but I just left a job (WalMart) and it was a hill Phoenix cascade rack and we added co2 but we used a regulator and it took forever is it ok to add straight tank pressure to the system. I’m new with this co2 stuff looks like that’s what you did and probably was way faster just wondering any info would be awesome
