White Glove Delivery - Available -

What is White Glove service?

Standard common carrier delivery options cover the cost of getting an item to your shipping address but our White Glove delivery service does that and more!

The White Glove agent will call to schedule a Call Before Delivery within a four hour window, which gives you the flexibility to work around your busy schedule and to prepare the space where your item will be placed. Upon delivery, trained professionals will unload your large item from the truck, bring it into the room of choice, unpack the item and remove all packaging debris from the premises.

Please note that White Glove delivery will typically add 5 - 7 business days to your order's transit, and only includes 30 minutes of on-site time. If on-site time beyond 30 minutes is required, you may be responsible for additional fees. While the agents will bring the items into the location of your choice, this service does not include set-up of the items being delivered, such as installation of casters, shelves, or other accessories. Small items will not be unpackaged individually; they will be set in place and debris and packaging material will not be removed.

Customer Q&A Ask a Question

I haven’t heard of R290, R600a, or R513a refrigerant before. What is it?
R290 (also known as high purity propane or CARE 40) and R600a (also known as refrigerant grade Isobutane or CARE 10) are hydrocarbon refrigerants. R513a (also known as Opteon XP10) is an HFO (hydrofluoroolefin) refrigerant. 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 is rear and side breathing, and for proper ventilation it requires 3" of clearance behind it and on the sides.
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.

Depending on the model, these back bar refrigerators are built to accommodate two or three kegs, hundreds of bottles, or over a thousand cans so you never run out of drinks. These coolers are all made with heavy duty steel exteriors covered in a wear-resistant black coating to ensure long-lasting durability. In addition, their interiors are all made of type 304 stainless steel to resist corrosion and spills. And the stainless steel top fits smoothly underneath your bar or functions as a countertop. Every Avantco back bar refrigerator comes with a high-powered, side-mount compressor that circulates R-134a refrigerant throughout the body, while the walls are packed with foamed-in-place, high-density polyurethane insulation to help maintain temperatures between 33 and 41 degrees Fahrenheit. A lock and key are included to make sure your stock stays safe during off hours.
