The Liebherr Monolith MRB3000 is a 30-inch, 15 cu. ft capacity, built-in refrigerator column that rises to a staggering 84-inches, literally taking food preservation to new heights. This model is very energy-efficient, using just 305 kWh/y, while similar models use up to 447 kWh/yr.

PowerCooling ensures that newly stored foods are quickly cooled, while maintaining an even temperature throughout the interior, and Monolith circulates cold air behind the door, meaning that items stored in the door stay just as cold as everything else inside.

Energy efficient features

Part of the energy saving capabilities of this refrigerator come courtesy of BioFresh, an advanced food preservation system featuring independent climate controls with the use of a divider.

This function means you can create a high-humidity environment for fruits and veggies in one drawer, and a low-humidity environment for meats and cheeses in another, while a third drawer can be set as BioFresh-Plus, lowering temperatures down to 28°F, ideal for storing fresh fish and seafood.

Smart features

One unique feature of this model is Liebherr’s smartphone app, SmartDevice, which links to a SmartDeviceBox that can be controlled via a smartphone or tablet, activating settings and features while on the go.

SmartDevice can use internal cameras to let you see what you’re missing for any given recipe, arguably saving you time and money by making sure you don’t have to make additional runs to the store. You can even use voice recognition to order what you’re missing.

Water filtration

This model includes InfinitySpring, an integrated and flush-mounted internal water dispenser that accommodates pitchers of any size and uses a filtration system to eliminate harmful contaminants. And, you can safely store gallon jugs of in the door, freeing up the refrigerator’s interior shelves.

Depending on which size Monolith you choose, the door hinges are rated for up to 79 pounds.

Noise and light

The Monolith is very quiet, with a sound rating of just 40 dBA, and even offers customizable lighting.

The integrated LED side-wall lighting creates an even glow that can be adjusted according to taste, including a soft brightening effect upon opening the doors, and a night dimming feature.

The Monolith also features Liebherr’s InfinitySwipe touchscreen display, an intuitive electronic touch-control panel featuring a full-color 2.4-inch touch and swipe screen that’s bright, clean, and wonderfully user-friendly.

Additional features we love

Doors close automatically and gently thanks to SoftSystem technology, which eliminates slamming even when shelves are fully loaded, and drawers move on smooth telescopic rails for soft closing. The Monolith has a Star K certified Sabbath mode, interior stainless steel finish to help eliminate odor trapping, 4 cantilevered glass shelves, 2 crispers, and 3 adjustable door bins, and the doors are reversible and can accept custom panels. 

Liebherr warranty and reliability

This model also has an impressive warranty that puts it out in front of its competitors: 

  • Parts & Labor:  2 Years
  • Sealed System:  5 Years
  • Sealed System (Parts Only):  6th through 12th Year.

Sustainability at Liebherr

Liebherr were the first manufacturer to convert their entire appliance range to HCFC/CFC-free refrigerants, back in 1993, and Liebherr Appliances in North America was one of the first refrigeration manufacturers worldwide to be fully RoHS compliant by restricting the use of hazardous substances.

Liebherr uses environmentally-friendly powder coatings without using any solvents when finishing sheet metal, and doesn’t produce waste water that damages the environment. The company also recycles heat generated during manufacturing to heat its offices and production sites, and all of its plastic components are labeled to ensure easy and optimum recycling.

All Liebherr production sites are certified to the international quality standard ISO 9001 and to the international environmental management standard ISO 14001, and all appliances meet and, in most cases, exceed the requirements of ENERGY STAR®.

Liebherr vs. Blomberg

This impressively eco-friendly, high-performance model uses less energy than the Blomberg BRFB1822SSN Refrigerator. The Monolith also has a fantastic warranty, so if money allows, this is the one to go for, especially because it also has RoHS and REACH certifications unlike the Blomberg. Thanks to that comprehensive warranty, you’re in good hands with Liebherr, a company long committed to good environmental practices.

Final thoughts on the Liebherr Monolith 3000

Liebherr’s Monolith is an impressive feat of engineering, marrying style and function seamlessly. It is super quiet and very inconspicuous in the modern kitchen. This 15 cu. ft refrigerator is very energy efficient compared to similarly-sized models and is highly customizable, so you can keep running costs low and performance high.
