It is Friday morning, no rush and taking it easy. Txv found completely shut in the evaporator with the sensor . This was causing the of freezing product on the other end by the other evap.

Love it when they go as planned.
Filter drier.
Nitrogen purge.
Triple evacuation.
500 micron vacuum held.
From put in park to put in drive 1 hour 45 min
Site left cleaner than found.
Food stocked back into cabinet.

Nice work!! Is that some type of heat transfer material in the txv?

 

[Gary Warren Jr]

Wet Rag! Great stuff for those hard to reach places. The trick is to remove ASAP as it holds the heat! The small tubing did not take a lot of heat to braze so I took the time to take a picture before removing.

I love it when a plan comes together!

You are not joking! Lately , on a few units, I have spent 2+hours just pulling moisture out of a system in a pull down, to finally have one that comes together as planned, ON A FRIDAY, was pure bliss!
I had one last year that had so much moisture in it I had to pull the compressor and drain the oil, it had a hole in the condensate heater, which was nothing but the condensing coils tailpipe, so it just sucked water in on off cycle.

Thats where Stay Brite #8 is worth it...............Plus no burning of other components.

I pick it all off and put it back in the tub to re-use.

Nice work on the replacement valve.

Look at all those six pans and drawers/doors. That's a good size unit.

 

[Red850kid]

Do you wait for the box to pull down and check/adjust the valve?

I know sometimes they come close out of the box. I typically like too see it between 10-12 degrees on coolers.

 

[Gary Warren Jr]

The box had satisfied with 15 minutes of the job being done.

 

[Gary Warren Jr]

Sorry. I did not adjust the valve. Due to having to remove everything and heating the coil up doing so, I am not sure if you could dial it in any better than the manufacturers preset settings. Don't get me wrong , if the box showed similar symptoms or had an issue, I would look to see if for some reason it was out of wack but since it satisfied within minutes , I left it alone.

Is that a Delfield ?

Russell

Would you have brazed in the txv with stay brite and no wet rags of any kind?

 

[Texas Pete]

You mean Randell not Russell.
I’m impressed with how clean that kitchen is and no crew in your way.
Usually I’m crawling around dodging the hash slinging slashers that man the grills trying to avoid all the grease and food escaping the grill from the all the slinging. :grin2:
Just sayin….

 

[Red850kid]

Yeah nice unit too.

 

[Red850kid]

Would you have brazed in the txv with stay brite and no wet rags of any kind?

I for one would have, but still thrown a wet rag over the valve quickly.

With a small map torch that would be heated up in 8-10 seconds and done.

Being able to braze it without choking yourself or burning up the cabinet is a skill you seem to have acquired.

I might also say the nitrogen purge is not AS required with the SB.

Brazing means over what 1600*!

Staybrite 8 8 - 900* F

Real refrigeration men braze AND can solder too.
Professional refrigeration craftsmen know how NOT to burn up the TXV and the appliance they’re trying to repair.
Just sayin…:.02:

If you are insinuating something please just say it Pete. I have probably soldered more pipe then most ever seen. All my joints in miles of pipe sized from 4" down looked brand new. BTW that TXV is just fine

 

[Gary Warren Jr]

OK. I may have misread your post. The "just sayin" at the end hit me hard. Haha. Yes you are right , it is a Randall not Russell.
