How do you deal with a leak in walk in freezer

[Peztoy]

How do you you guys deal with a refrigerant leak in walk in freezer. 10 ft x 20 ft freezer is loaded with product. It's his only freezer. Leak is on the rooftop condenser return bend. How long do guess I've got to bring it back online before the stuff gets questionable?

Keep the door closed and pump it down. Isolating the damaged part of the system will really cut down evacuation time and you'll be able to get it back online sooner. I usually say it's going to be offline for 4 hours. It's always better to tell the customer it's back up sooner than expected rather than tell them it's gonna be down longer than expected.

Might be hard to isolate being the condenser that needs repaired. I don't think he is going to get it all in the receiver. Even if he could how would he isolate it from the condenser without a service valve in between the two ?

Yeah, i just read it again..condenser return bend...then the 4 hour prediction would be right.

Customer wanted a quote. Now I wait.......less then a week.
It's blowing good bubbles.

Take all the time you need. All that frozen food would take a loooooooooooong time to thaw out, probably a few days.

You can get that done quick.


Let them know to keep the door closed, isolate it, pull the charge, braze it up, quick vacuum and let 'et rip.

I like to have everything laid out, hooked up, ready to roll before I start. Manifolds and recovery machine hooked up, vacuum pump hoses ready, everything ready to roll

I use a box, tub, or bag filled with ice and surround the the recovery jug with ice to take away the heat of the recovery process. Seems to nearly double the speed of refrigerant recovery.

I would think dropping the temp say 5-10*F an hour or two before the repair would help out too?

I am not much of a refer tech but it makes sense.

Peztoy,
Can you get to the leak ? Or are there non removable covers ?

Can it pull down when it's low on gas? Adding gas to freeze product might take a lot of time and gas. Customer is understanding type?

Yes it can pull down with less gas.

The gas was already added to get them through until the repair could be made, no customer is going to lose a freezer full of product over a few pounds of gas.

My question is, is there a reason why you would NOT drop the box temp as low as possible before shutting the system down for repair? I would think the lower temps would allow for more repair time or some fudge factor incase things go south with the repair?

We all know they didn't place the service call until the food was already soft anyway.
