How did you replace captube into a TXV?

just vacuuming, disassembled and brazed some replacement parts :p:

therefore I need your advice, the right ev for my phase change systems

for first stage use the danfoss tes2 works with 507/404 i would stay away from 410a unless you have very good condensing on the first stage


there is only one txv that would be any good but its for r23(danfoss teb2) on second stage that you can buy in a shop

to make one work with 1150 you will need to change the gas in the txv bulb to 1150




i get my cpevs from piotres

As bazx said :).

IMO :

1st stage : Dafoss TS2 or TES2 plus 01 or 02 orifice (01 rather) plus R507
2nd stage : Danfoss TEB2 if You can use R23 there
3rd stage : I have no idea, I only have experience with Fach CPEV.
