Temperatures in this True TSSU-27-08-HC sandwich and salad prep table are adjustable to suit different applications, and users can set it on any level between 33 and 41 degrees Fahrenheit. Self-contained with the components in one place, the refrigeration system uses R290 hydrocarbon refrigerant—an eco-friendly option—to maintain these temperatures. If there is an issue in the system, the operator can access the condenser from the rear with its slide-out design.
