GENERAL
U, UB, and DU Undercounter Food Storage Cabinets can be equipped for freezer (0°F) or refrigerator
(38°F) operation. The condensing unit can be self-contained or remote (supplied by others). The
equipment compartment can be specified for the left- or right-side. Refrigerators use R22 refrigerant;
freezers use R502 (remote freezers may be R22 or R502).
Undercounter Food Storage Cabinets may be ordered with one-, two-, or three-sections with a door
or two drawers in each section. Pass-through cabinets are available (U Series only) with doors front
and back – no drawers. Glass doors are optional on U Series refrigerator cabinets; pass-thru cabinets
cannot have more than 50% of the doors be glass. U and UB Series drawer sections are front opening
only (not available with freezers or pass-thru cabinets).
UB Series Food Storage Cabinets are built nine inches shorter than other U Series cabinets. Ideal for
use as a refrigerated base under countertop cooking equipment, UB Series cabinets are equipped with
drawers (standard) or solid doors (optional).
U and UB Series cabinets are available with S or C material codes. In the table below, S denotes
stainless steel; C denotes silvertone PermaShield polyester coated steel; G denotes galvanized steel.
DU Series cabinets feature a combination of Alum-a-Shield, stainless steel, and galvanized steel.
