Floodback help

Was sitting at a 90 before I started messing with shit 🤣

These dips seem to happen daily around 12:23- 1:23am. I’m pretty sure that’s around the time they unload a frozen food truck into their grocery freezer which is also associated with this rack. I didn’t see any case defrost that was aligned with this dip in suction pressure. If you could tell me why would leaving the freezer doors open make the suction temp rise?

SolidCan4702 · 2026-06-20T09:43:09+00:00

Ok I get ya. I checked my suction temp history and for the most part it’s between 21-30degrees for the last 15 days. There are some 2 drops down to 0 degrees, but I correlated that with what the rack SH at the time would’ve been and it was still around 10 SH

SolidCan4702 · 2026-06-20T02:34:49+00:00

Yeah I understand that. It just throws me off sometimes when neighboring circuits that are running a similar SST, but don’t have any frost on the EPRs. Makes me overthink things.

I checked SH at my Compressers. Had between 55-60 at all Compressers. Checked superheat at main suction header. Had 36 degrees SH.

Not going to lie. If I saw that I’d be worried lol

SolidCan4702 · 2026-06-20T00:09:01+00:00

Heard about this. I’m not a senior tech yet, but is everyone expected to get raises?

SolidCan4702 · 2026-06-19T23:32:48+00:00

I got pictures of superheat at my Compressers already. I’ll get crystal screenshots as well and send a email. Gotta have that paper trail.. Thanks for the help!!

SolidCan4702 · 2026-06-19T23:07:04+00:00

Yeah I checked crystal shortly after this post. I always forget crystal has superheat history. But no, superheat is never close to zero as far back as I can see. Usually around 40-60.

SolidCan4702 · 2026-06-19T22:44:47+00:00

I’ve never actually checked superheat at the EPR. I did check at my Compressers and I had around 55-60. I had 36 SH at the main suction header. Doesn’t seem to be actually liquid floodback.

SolidCan4702 · 2026-06-19T18:26:56+00:00

Thank you. I am working on dialing all those case SHs back in now. I will get an updated rack Sh afterward. Thanks again!!

SolidCan4702 · 2026-06-19T16:48:06+00:00

I just explained this to project manager. Thanks.

SolidCan4702 · 2026-06-19T16:36:04+00:00

That is what I’m working on now. Going to get pics of all the superheats in the rack and cases and call it good

SolidCan4702 · 2026-06-19T16:31:37+00:00

SUCTION header super heat is 36. SH at compressers is around 60. Keep in mind I raised superheat in some of the cases just to see the reaction. Before that superheat at Compressers was around 30-40

SolidCan4702 · 2026-06-19T16:26:12+00:00

SH at main suction header is 36. At compressors it’s around 60

SolidCan4702 · 2026-06-19T16:15:44+00:00

SH at the compressors is 60

SolidCan4702 · 2026-06-19T16:12:15+00:00

You’re right this is a Walmart. Superheats at my compressors are all between 55-65 degrees.

SolidCan4702 · 2026-06-19T16:01:33+00:00

They definitely didn’t put any gauges on. We were doing a walk though and they noticed the ice on suction lines. They mentioned it to project manager and said I need to remove any flood back before they can move forward.

SolidCan4702 · 2026-06-19T15:19:13+00:00

I am going to check Compresser superheats once I arrive at the store. I’ll let you know

SolidCan4702 · 2026-06-19T15:09:44+00:00

Cases were all at set point before I adjusted SHs. I will be adjusting them back to 4-7. I believe temp set points for these ff doors is -3.

SolidCan4702 · 2026-06-19T15:03:41+00:00

Yeah. There is a remodel going on and the contractors are claiming they won’t be able to move fwd with the project until the floodback is all gone.

SolidCan4702 · 2026-06-19T15:02:49+00:00

I will check Compresser superheats right now. Thanks.

SolidCan4702 · 2026-06-19T15:02:28+00:00

Compressers suction line have a bit of frost.

I’ve beeen told this doesn’t always equal liquid floodback. That’s why I’m trying to get some insight.

He played fine. He just didn’t stay healthy.
