Eco-Friendly Refrigeration

This back bar refrigerator ensures optimal performance by operating with a 1/4 hp refrigeration system that circulates environmentally-friendly R290 hydrocarbon refrigerant to maintain temperatures from 33 to 40 degrees Fahrenheit. R290 refrigerant has an ozone depletion potential (ODP) of 0 and a global warming potential (GWP) of 3, making it an environmentally-responsible choice for your business.

Self-Closing Doors with Stay Open Feature

The doors of this unit stay open when they are opened past 90 degrees. If they are only opened less than 90 degrees, they automatically swing closed to help save energy! This not only helps your employees easily load product without the door closing on them, but also helps make sure the door closes properly when quickly reaching into the unit without fully opening it. The tight seal prevents potential energy loss.

Customer Q&A Ask a Question

I haven’t heard of R-290, R-600a, R-513a, or R-448A refrigerant before. What is it?
R-290 (also known as high purity propane or CARE 40) and R-600a (also known as refrigerant grade Isobutane or CARE 10) are hydrocarbon refrigerants. R513a (also known as Opteon XP10) and R-448A (also known as Solstice N40) are HFO (hydrofluoroolefin) refrigerants. They are being used as an eco-friendly refrigerant by some manufacturers in response to the EPA’s Significant New Alternatives Policy (SNAP) Program. Read more about this program in our blog post on Refrigerant Regulations.
Can this unit be built into cabinetry?
It should not be built into cabinetry. This unit requires 3” of clearance on all sides for proper ventilation.
I'd like to install casters on this unit. Do I need 8 casters?
Yes, this item requires 8 casters. For convenience, we offer a kit with all of the casters and the M8-1.25mm x 20mm bolts required to mount them. See the Items You May Also Need section.
What if my Avantco cooler doesn’t seem to be getting cold enough throughout the cabinet?
Make sure that you are loading it properly, and not overloading it. This unit is designed for cans, bottles, and similar items that naturally enable good airflow within the cabinet. Overloading the cooler with cases and boxes will interrupt the airflow and negatively impact the unit’s performance.
Does Avantco warrant this item for use in a food truck?
Avantco warrants new equipment sold to food truck customers to be operational for a period of 30 days from the date of delivery if installed and maintained correctly.

Here's some basic settings you can make to your Avantco refrigerator in your restaurant. If you want to adjust the temperature, you hold set for one second and you'll see your low temperature limit. This unit is set to shut off at 33 degrees. If you want to have it shut off at a warmer temperature you can adjust it up. But it will not go below 33. You see when I get to 33 it just cycles back up to the top of the temperature range. Take this unit back down to 33 degrees. Press set to save it and you're back to your home screen.

    unit shelf shelves switch light nice power top bottles cooler
    1 out of 2 found this review helpful
    We purchased this unit to replace a another unit which recently had the compressor go out after 9 years. There are several nice features about this unit. Unlike the other unit there is no bump down above the top shelf which prevents full use of the shelf. This means we can get a lot more product on the top shelf. The led lighting is also a nice bonus over older florescent tubes. Finally, having the light switch on the front of the unit is a god send after having to deal with the switch being behind the top shelf like on the other unit. There are few things which prevent this from being a 5 star unit. Firstly while the light switch on the front is nice, having the main power switch right next to it is not. Undoubtedly this is going to lead to a bartender accidentally turning the power off completely while closing. Relocating the power switch or adding a flip cover would greatly help to prevent an accident. While the led lighting is nice it consists of only one strip across the top. Once the cooler is filled this means the bottom shelf gets only minimal light and product is not well displayed. A light strip down the center bars between doors would do a lot to help properly illuminate product. Finally, and perhaps the biggest problem is the shelves are not strong enough. I first discovered this issue about a quarter of the way through loading the first shelf. By then the bottles stared to slide towards the center making loading very hard. I even had to check the wight capacity which is stated at 90 pounds. A fully loaded shelf should hold about 80 beers or 90-100 pounds meaning you have to leave open space to ensure not going over the limit. This is a simply a waste of cooler space. And regardless, long before 90 pounds the shelves begin to bend. Bend so significantly that there is no longer room under the shelves for a beer bottle (See Pics). Meaning you have to push the shelve up with bottles under them to fit them in. This issue alone is the reason this is not a 5 star unit. I find it hard that properly sized shelving that could support the product the unit is designed to hold would have added that much to the cost of the unit. I would have been happy to pay a few hundred extra for a unit with shelves as strong as our old units. At the end of the day the shelves will be a big deal for us. We still have another unit which is the same size we were hoping to change out before it went like its twin. While I was hoping to change it for the same Avantco we may have to consider stepping up to another unit. Read Less Read More
    Thank you for your feedback! We’re sorry you did not prefer this product. For recommendations, please contact our Customer Solutions team.
    I will follow up on this review after 1 month of operation, but I have to immediately put this out there. I felt I was in the twilight zone today when I receieved a call stating my delivery was arriving in 1 hour, that was at 11am and I placed the order at 3am in the morning! I literally got the cooler delivered to me about 9 hours after ordering online!!!! More on its performance later as I said, and I'll post photos and videos of it in operation then. I did plug it in to test and everything appears fine so far. Cosmetically, it looks great.
    Spacious refrigerator with good insulation and cooling abilities. Faulty cooling pipes in the back get too cold and make beer slushy sometimes but overall a great design that performs up to par.
    This unit is a beauty. It works great as well. Easy to clean. Durable, and most importantly, your beer stays nice and cold. Highly recommend.
    I can't complain about this cooler. I can easily give a 5 star But on label the light switch powers on/off and the power button does the lighting as labeled..first night full. got shut down luckily we only have water and soda ...besides the labeling part 5 stars
    We appreciate your feedback! We’re sorry this was labeled incorrectly. A Customer Solutions Representative will be contacting you soon.
