So-Low's Superior Construction

Ultra low freezers have a 16-ga. exterior (cold rolled steel). Interiors are 14 gauge vs. competitions 16 gauge.Ultra low freezer interiors are galvanized, non-corrosive steel. Galvanized steel conducts temperature more efficiently than stainless steel. This creates less stress on compressors making them run cooler and longer.

So-Low's Digital Control

So-Low is the only ultra low temperature manufacturer to utilize a dual display digital temperature control. A red LED display indicates the actual interior chamber temperature while a green LED display located directly below the red display shows the actual setpoint temperature. This will give assurance that the freezer is operating at the correct temperature range whereas other manufacturer's temperature controls show only the actual temperature and not both the setpoint and actual temperature.
