The Cesaroni Design industrial design firm worked closely with the marketing and engineering teams at Sub-Zero to create a new concept of food preservation. The PRO 48 is the largest combination unit the client offers. This appliance can be freestanding or built-in for a more integrated look. 

The appliance is constructed of almost 100% stainless steel. A glass door offers an elegant transparency to an otherwise stainless steel sculpture. The refrigerator cavity is designed with channeled sidewall LED lighting that acts as a door area night light.

Innovative human factors considerations drove the development of the new product design. A unique auto-close system utilizes precision built hinges to prevent the door from slamming shut. The cam takes over to close the door the final 15-degrees.

Two stainless steel bins are designed to fit under the refrigerator shelf. The versatile design is oven-safe so a consumer can marinate meat in the bin overnight, and then transfer it directly to the oven.

An upper drawer is a crisper compartment specifically developed to store vegetables. Its clear view window enhances visibility inside the compartment. The drawer divider design is interchangeable for complete compartmentalization.

The electronic control system gives the consumer the ability to set a different temperature for the two refrigerator drawers from the temperature for the door cavity. The temperature in three separate areas is digitally displayed on the exterior of the appliance.

This new appliance design was featured in WIRED Magazine as Top Ten WIRED Tools and was also recognized by The Chicago Athenaeum with a Good Design Award.
