Hi Fellow DIYers,
I'm starting a DIY split-unit aircon chiller project with drop-in coils.
However, i'm not too sure where i can get adustable expansion valves so that i can control the temperature at every coil.
Anyone have seen ppls selling or know where to buy?
If You have similar experience on the setting up, please share with me as i have never done DIY project of this scale before.
Thanks!!
