Your welcome. Working with a refrigerant like CO2 you have to be safe. Wear the proper ppe, understand that those cylinders are heavy and at high pressure. Don’t forget you can cause dry ice in your hoses and always shut off the cylinder valve and bleed off the hose before removing. Good luck out there.

I'm starting to see Coke coolers using Co2 would like to see videos on compressor replacement.... guessing these are stainless steel lines how do u solder or are these coolers just going to be trashed not repaired if so how is that "saving" the environment ?
I believe they would be copper lines not stainless. You see many gas coolers that are copper with stainless headers because they have thicker walls and can handle the pressure. Always follow up with the manufacture.
Once the cylinder pressure equalizes with the system pressure, your create a pressure difference by supplying heat to the cylinder . If you are not sure how to do it safely, then don't attempt it. I have an experience charging an HFC system, where the cylinder pressure and system pressure equalized after only 4 cylinders, and yet I need 20 cylinders as initial charge (10MT/day tube ice machine). Using a 500 watt lamp array as heat source I was able to complete the 20 cylinder charge into the receiver. To keep the pressure low at the receiver while charging , I had to apply ice on the liquid receiver to condense some of the vapor so that the receiver pressure remains almost constant.

Not with fire but with a lower intensity heat source like a cylinder heater blanket w/ thermostat (if its available for CO2 cylinders). A 500 watt halogen spotlight might do the job too.
A large hot water bucket works better and safe than torch. The best way to avoid dry ice if is a new system or previous blown charge ,first switched the relief valve to 1700psi , turned off all circuit solenoid and start with vapor to 145psi and than start adding liquid and complete your charge without any problems. The receiver is sized for a full charge with a total of 80% receiver capacity. With that said now you have your charge in system open one circuit at the time and watch the process. Always stay focused to all your input. Be safe out there ✌️
Thank you for this underrated series
Keep learning and keep sharing that knowledge.
Exactly the information I was looking for. Thank you.

Whoa I knew you were local to me but didn't realize you were also in Brantford!

They used thicker copper, filter drier also heavier than normal ones, few of my technician friend got the drier burst out by using normal ones
Does emerson do co2 system trainings? In the US, Midwest.

I like that make sure you understand what your are doing and get the proper equipment like cylinder heat blankets if needed.
Do you have a part number for the brass tank adapter?

Co2 ? A brand of Coca-Cola 20 cubic foot coolers have Co2 refrigerant , Unusual find in Canada .
Yes I have also noticed many Coke cabinet fridges using R744
what about heating CO2 bottle with fire while charging sistem?
I do not recommend that. Have a second bottle and let stalled cylinder warm to room temp.
Not with fire but with a lower intensity heat source like a cylinder heater blanket w/ thermostat (if its available for CO2 cylinders). A 500 watt halogen spotlight might do the job too.
I like to use my oxy acetylene torch. I heat the cylinder until the paint bubbles and melts.
