An Overview of Sub-Zero Appliances

The Sub-Zero Freezer Company manufactures a range of high-quality, high-end appliances that are preferred by chefs throughout the world. Sub-Zero founder, Westye Bakke, devised the first stand-alone food freezer shortly before founding the innovative appliance company in 1945. In the 1950s, Sub-Zero debuted the world’s first refrigeration unit that could be installed in a wall. Since that time, the Sub-Zero brand has garnered a reputation for innovation and excellence that remains unparalleled. In the 21st century, Sub-Zero appliances includes refrigerators, food freezers, under-the-counter refrigeration units, side-by-side refrigerator-freezers, chilled beverage centers, ice makers and wine coolers. Here are a few examples of the Sub-Zero products that are available today:

Sub-Zero PRO 48

Made with 100% stainless steel, this professional grade refrigeration unit features three evaporators, microprocessor controls and fresh produce drawers that can be adjusted separately from the main refrigerator compartment. A digital displays allows for precise temperature control. A fashion-forward optional glass door provides UV resistance for perfect freshness preservation. As with all Sub-Zero refrigeration units, the PRO 48 comes in classic stainless steel with custom panel options.

Sub-Zero BI36RGSPH

This 36-inch fridge-freezer combo offers plenty of space for fresh and frozen foods. This Sub-Zero refrigerator/freezer unit comes with four fully adjustable spill-proof glass shelves, a humidity-control produce drawer, two sealed produce drawers, an air purification system and a UV-resistant glass door panel. Sub-Zero under-counter refrigeration units provide ideal chilling for bars and cocktail lounges, patios, restaurants, living rooms, dormitories and family recreation rooms. Sub-Zero under counter units are rated for indoor and outdoor use.

Sub-Zero wine storage

Oenophiles protect their investment with built-in and stand-alone Sub-Zero wine storage units. These world-class coolers keep wine at optimum temperature while providing protection from the four enemies of wine: vibration, light, heat and humidity. Sub-Zero wine coolers are available with one, two or three drawers. Dual evaporators and easy-glide racks provide perfect protection for valuable bottles of wine. Exceptional labels remain visible through UV-blocking glass door panels. Independent storage zones allow for custom temperature control. The Sub-Zero 424 wine cooling unit can keep wine chilled to 38°F (3°C). The 424 features two custom-controlled temperature zones and can be connected to a security system for added security and protection of a valuable wine collection. Sub-Zero refrigerators tend to outweigh the competition. An average unit made by GE or Frigidaire generally weighs in at around 250–300 pounds (110–140 kg). A typical Sub-Zero unit can weigh a whopping 800 pounds (360 kg). The Bakke family protects the prestige of Sub-Zero cooling devices by fully vetting any and all vendors who wish to sell their products. At a time when so much manufacturing has moved to China, Sub-Zero remains a proud, family-owned maker of all-American products. As of 2015, Sub-Zero appliances are manufactured at production facilities in Fitchburg, Wisconsin, Phoenix, Arizona, Madison, Wisconsin and Richmond, Kentucky.
