ADC may have distributors for it's commercial laundry products, and or have an internal sales force. You will not find these units at your local appliance type store. Despite the blurb about "residential" use, IIRC, ADC is like Speed Queen's "HomeStyle" laundry appliance range. Designed for light commercial (motel, small hotel,bed and bath,beauty salon, restaurant, etc.)use, and secondary for residential use. While the units do run on 120V power, they are not exactly "small". One would need a pretty decent sized laundry area to install these units. Probably along the order of a "small" MacMansion.
The seller of the units shown above seems to be some sort of financing company, probably dealing with commercial laundry equipment. As these and other units he/she is selling are used, they probably are either off lease or perhaps even repossesed items. Or simply a laundry closed down and returned it's equipment to the owner, who could be this credit company.
Don't let the photograph fool you, it is the same stock photograph shown each time the auction is run.
