Using technology that was developed by NASA, Sub-Zero’s air purification system slows down that process. Many foods emit ethylene gas, which is natural, but ethylene gas accelerates the spoilage process.

The seals are so secure that Sub-Zero owners have reported that even after a days-long power outage, their frozen food hadn’t thawed! Air Purification System This system helps keep food fresher longer and makes for a more energy-efficient refrigerator. The magnetic door gaskets around each door lock cold air in and keep outside air out. It provides optimum conditions for each type of food. Meanwhile, the freezer gets frigid, dry air that prevents frost and freezer burn. In the refrigerator, food stays fresher longer with cool and moist air. With this technology, there are two completely different cooling systems. This means that there are two compressors, one specifically for the refrigerator and the other specifically for the freezer.

Integrated refrigerators take it a step further, allowing for custom panel installation that matches the rest of the kitchen’s decor. Sub-Zero built-in models fit seamlessly into virtually any kitchen. They’ve pushed the envelope even further over the years, introducing a line of built-in and integrated refrigerator models. One of their most notable innovations was the counter-depth refrigerator, which was not duplicated by any other major brand until 20 years later. Sub-Zero has been in business for nearly 70 years, innovating many advances in refrigeration technology. Here are some reasons why they’re worth the price of admission: Built-In/Integrated Refrigeration That’s no different in the world of home refrigeration, and Sub-Zero products have only grown in popularity due to their quality, performance, and features. With most things in life, you get what you pay for. Why Sub-Zero? Here’s a closer look: Are Sub-Zero Refrigerators Worth The Cost? However, with the highest quality features and excellent appliance longevity, Sub-Zero refrigerators are well worth the investment. Sub-Zero has a respected reputation for building top-of-the-line refrigerators, but it’s natural to wonder, “Are Sub-Zero refrigerators worth the cost?” After all, you can furnish an entire kitchen for the cost of a Sub-Zero fridge.
