Odd Beer Case issue

[gatorfan9606]

Ok i got a 24ft line up of Beer( Hill O5DM Case) the issue that im having is i'm getting some mold on the Beer packages.
My case setpoint is 36* my rack is 404a +20SST. I've played with 3 defrost a day and 4 at :42min. I've set my term at 45* etc...... My store conditions are 72*- 53%R/H -S.Heat on both is 6-9*. The highest the temp gets during defrost is 43-46* its controled by an E2E- suction epr is a (CDS)
I'm just don't know what else to look at my rack and case are spot on all my fans,and fan blades on the cases are good not bent. My a/c's are also working as they should. I don't have any excess air entering these case either. The beer itself is cold and fine its just the package that gets small sections of mold or mildew: THX

Where is the beer being delivered from?

[gatorfan9606]

there is a staging area in the stock room where the conditions are good as well

[catalina_mike]

Are the fans coming on before the coil temp is low enough to cause the condensation not to blow into the case?

Do they often have broken bottles? If someone breaks a bottle and splashes beer all over, you will get mold spots

There is a problem BEFORE the beer is loaded in to the cooler. Some distributors keep their beer cold then put it in a warm truck for delivery. It could also be in a cold truck and sweats in a stockroom somewhere before it gets put in the cooler. Once the cardboard gets wet and is stacked together with other cases, it is very hard to dry it out.

These both sound like reasonable explanations.

I'd also throw this one out there.

I have had several issues with HP cases not having the correct airflow.

Either they're installing the wrong motors at the factory or they're publishing the wrong specs.

I know that new, proper motors corrected it, so I'm betting that the specs aren't wrong..

I have thought of that cause out of all the cases in this store this is the only line up with the issue. I have called HP and they have assured me i've got the right motor package

not that i have seen or smelled

Does your airflow match their published specs?

They insisted all day long that they had the proper motors.

Even sent the wrong motors to me again.

Got an engineer on the phone, beat him up a little and got the correct motors in.

Haven't heard a peep since.

yes it does and i don't lose any airflow at all. At first i thought my coil was frosting up right before defrost but that wasn't the case

The fans that are in this case are that ECM motor and blade combo they are black i forgot the exact name of it

Ok, we'll toss the airflow idea out.


I'd think real hard about the product getting wet before it is stocked.

Cold beer onto a warmish sales floor, then into a case.

I see that condensing.

Yeah, those are the ones.

The ECM is programmable to different RPMs

[gatorfan9606]

I'm thinking this is a product issue and not a Refri problem....i have graphed these cases for over 5 days and its like clock work they don't hit 50* idk
