Running through the self-contained capillary tube system, R290 hydrocarbon refrigerant keeps the True TUC-48F-HC undercounter freezer at an average temperature of -10 degrees Fahrenheit. The condenser and evaporator fans provide even airflow, reducing heat production and conserving energy. Its evaporator is epoxy coated to resist corrosion, and for cleanup and maintenance, the condensing unit is accessible from the rear and conveniently slides out.
