    Looks like theirs a big difference in your anti sweat amps. Don’t know what other than door issues you would face.
    Honeywell you can buy better but you cant pay more

    There aren't nearly enough heaters in the medium temp case to allow for low temp operation. It would freeze up everywhere quite rapidly. The coil fin spacing is too tight and the distributor usually needs to be changed. The doors are likely strictly for medium temperature too, so the glass would sweat like crazy.

    I wouldn't try it. It will never work right, you'll loose money doing it and end up wishing you stayed home to watch the grass grow.

    This customer bought these cases at an auction and cant return them! As I do on every installation that I do I need to make sure that all the equipment is sized properly!! I reach out to all my resources then quote the job. I spoke with the Kysor/Warren engineer and explained the situation to him. He ensured me that the only difference between the QDV5V14 ( medium temp.) and the QIV5V14 ( low temp) is that the medium temp. doors has no heaters. According to him evap. coils and distributors are the same and no additional heaters. Will have to add drain pan heater in addition to the defrost heater. Using a 1 ton valve with a R404zp with the new FFAP 2hp will supply the required 1250 btu's per door at a -5 sst. I explained to the customer that his fancy LED lighting may not work through the iced up doors but his product will be frozen.

    My next question would obviously be what's the warmest temp. I can maintain for frozen food ?

    That's interesting about the no additional heaters in the case. I hope that guy is correct, for your sake.

    The doors will still need to be addressed though. It's not just a matter of not being able to see the product, the customer needs to know that there will be water running onto the floor posing a slip and fall hazard that any decent inspector would write him up for. In addition, the doors may well be frozen shut every morning.

    I understand your position with the customer, but he's the one who bought the case without knowing what it was. My advice is "you gotta know when to hold 'em and know when to fold 'em."

    Quote based on the return air temperature required by your local heath dept. or go with 0°F return. If you don't, the inspector can shut you down.
