    Just got a call, the R14 is ready to pick up at my local gas seller! Only waiting for the R23 now, which should arrive on Thursday hopefully.
    I won't add Argon for now. No need, and what I saw it gives only better idle temps but does nothing at load (only higher discharge pressure).

    Why using other refrigerant in place of R507? It's better to have higher suction pressure, thus higher boiling point ---> more capacity.

    I like how much space these things take up, but they are well worth it.

    Today I picked up the R14 and the R23









    Seems that I have a small leak in third stage. Found nothing with soapy water, rethightened the flares. I hope it is leak free now. If yes than I will charge it tomorrow.

    awesome cold_ice, you must have a fortune on gasses laying around by now Do you had to buy new regulators for those?

    I bought an Argon pressure reducer, fits for R14 and for R23. Hydrogen reducer fits for Ethylene, Methane and Ethane...
    I have a lot of gasses here now, will make a picture today.

    cold-ice: Where did you get the cheaper price for R14? I called messer today, and got a quota of 400€/6kg and 200€/100g... That small botle is insanely priced, but I dont actually have 400+tax+botlerent to spare at this time
    cool cool cool!

    I got the small bottle from Linde. 1,2kg for 150€ + tax and rent for bottle. Messer wants 450€ +tax for 6kg here...
    3rd stage seems to be leak free now, vacuumed it today. Also insulated most parts of first, second and third stage. Hope I can finish 4th stage tomorrow
    Pics tomorrow.
