The True TDD-4CT Draft Beer Cooler is a 90 inch unit with a club top. The TDD-4CT uses forced air cooling to keep the contents of the cabinet cool. It can store up to 4 half-barrel kegs at one time. Two 3-inch, insulated, stainless steel beer columns are located in the top center of the counter. The interior of the refrigerated compartment has galvanized steel walls with a 300 series stainless steel floor making it easy to clean.
