TXV Brazing Tips And Liquid Line Filter Driers
Вставка
- Опубліковано 3 жов 2024
- When brazing a TXV (thermostatic expansion valve) it must be done correctly. We also discuss liquid line filter driers briefly with Jamie Kitchen from Danfoss. The TXV brazing tips included in this video include the following:
1. Getting the heat on and off quick
2. Pointing the torch away from the valve
3. Protecting the valve from heat with heat absorbing putty (WetRag Putty)
4. Ensuring there is good silfos penetration and a potential shoulder
5. Nitrogen brazing
In this video we are using the Ambro Controls Oxyset with Precision Torch Tip, which allows technicians to carry a light weight tool and offers easier access into smaller cabinets due to its size.

Nitrogen brazing is a thing
Fan of the podcast from out of North Carolina
Thank you, I appreciate that!
Heat the joint first. If your gap is snug, heat will transfer quickly to pipe. If not snug, use a lever type swaging tool.
Geat video. I know you did not flow nitro for demonstration purposes, what is the best way to remove those flakes from that txv afterwards?
Using a flush system like RX11 flush but nitrogen will avoid all that. In reality RX11 is only for linsets
Always ask if the nitrogen cylinder has been used for clean nitrogen only. Sometimes the cylinder was used for some other gas and it just gets repainted. If it has had some other gas in it you now have dirty nitrogen and you can get high levels of copper oxide inside even though it's clean gas. If possible get only medical grade nitrogen, the sales person will probably give you a strange look but tell them that is what you want. And even with clean and pure nitrogen you will get some copper oxide build up.
Counter guy will zero idea about this
Cool Video. Brazing with Nitrogen is cool.. i put regulator on 3.. at 6 I notice nitrogen pushing out filler... had that ever happened to you
If the flow is too high yes, that can happen
Can you make a video about Stay Brite 8 as an alternative to high temp brazing?
I'm working on it
Heat the pipe then the joint
Heat the joint them move the heat away not bring it towards
Fantastic video and info thanks
My pleasure thank you! @@eastcoast186
Do you recommend always change your txv when changing a compresor.?
What is the main reason for the acces port?
