BioFresh has been a long-standing feature in the residential models of the global refrigeration specialists, offering an exceptional food preservation system.

By Dianne M. Pogoda

Liebherr, a global leader in technology, appliance, and heavy equipment manufacturing, has long been at the forefront of food preservation technology, ensuring that food stays fresher for extended periods.

With its exclusive BioFresh technology, Liebherr achieves the optimal conditions for food storage and freshness specifically designed for different categories: produce, meats/dairy, and seafood. By regulating temperature and humidity, the refrigerator’s individual compartments may be set to the exact needs of the food stored within, creating the perfect climate for long food preservation. These adjustable compartments offer flexibility to meet the homeowner’s needs at any given time.

The technology protects nutrition, appearance, and aroma, helping to reduce food waste. For example, a fruits-and-vegetable drawer maintains a temperature just above 32˚F and high humidity, creating an ideal environment for retaining vitamins, minerals, crispness, and juiciness. BioFresh technology also minimizes wilted greens and prevents ice damage. Liebherr research has shown that the fruits-and-vegetables food safe keeps lettuce fresh for up to 13 days and apples and kiwis for up to 80 days. Liebherr also offers HydroBreeze: a cold mist that covers fruit and vegetables like a protective balm. This cold mist, combined with a temperature in the safe of around 32˚F, gives food that extra boost for longer shelf life. And it creates a genuine visual wow effect. HydroBreeze is activated every 90 minutes for 4 seconds and for 8 seconds when the door is opened.

A meat-and-dairy drawer, on the other hand, may provide a drier environment with lower temperatures to preserve freshness and extend shelf life, while a seafood compartment is customizable for a lower temperature with lower humidity to preserve nutrients and maintain freshness longer. 

This revolutionary technology offers customized temperature control within the entire refrigerator as well, with individual drawers being set to 32˚F or lower and the rest of the interior being adjusted to a different temperature as needed. 

BioFresh is available in eight freestanding residential refrigerator models and 17 fully integrated models. Liebherr appliances are designed to be energy efficient, with all earning ENERGY STAR® certification, and some ENERGY STAR Most Efficient, and being produced in accordance with the company’s sustainability standards. The company is firmly committed to reducing its water consumption, energy use, carbon footprint, and environmental impact.
