This is a Walmart Freezer rack with Novar control. It is R404A with unloaders and all the bells and whistles. I am letting this go for a steal at $5500.00 for both rack and condensers. I had a customer back out of a deal at the last minute and I have it sitting. I will gaurantee unit and can provide delivery with one of our trucks depending on location for a fee. It can also be picked up in Chicago. Call 773 468-2653 and mention that you seen on HVAC-TALK
