Ultraefficient

Energy-efficient refrigerators and freezers help with ever increasing electricity prices. Liebherr fully utilises the savings potential of every component – from the compressor to the seal, to the lighting and electronics. The ultra-efficient appliances in the Perfection series for example demonstrates how this has a positive effect on your overall operating costs.

NoFrost technology

With professional laboratory appliances from Liebherr, defrosting is no longer necessary. Any moisture that occurs is bound by the fan-assisted cooling, and needs-based defrosting phases drive even the last moisture particles out of the interior. For convenient, safe, and ice-free storage.

LED front lighting

The LED front lighting provides optimal illumination of the drawers even in dark environments. Thanks to the perfect overview, the desired substance is immediately at hand, the door can be quickly closed again, and the interior temperature remains stable. For low consumption and lower energy costs.

DIN 13277 compliant

Laboratory and pharmacy refrigerators from Liebherr meet all the necessary features and performance criteria to fully comply with DIN 13277. DIN 13277 defines the requirements and test specifications for refrigerators and freezers used in laboratories and for storing medicinal products.

Ultraefficient

NoFrost technology

Integrated WiFi/LAN interface

Connect and go: The appliance can be easily networked with external systems, such as SmartMonitoring from Liebherr via the integrated WiFi and LAN interface. Thanks to the digital monitoring solution, the storage temperature is controlled and documented via the interface in an effortless, safe, and convenient way.

Mechanical lock

All professional Liebherr appliances are equipped with a mechanical lock with two keys for the storage of temperature-sensitive products. This way you can be sure that no unauthorised hands can access your stored goods.

Designed for a service life of 15 years

Sustainable means the appliance is not only economical, but also durable. High-quality materials and solid workmanship, coupled with at least ten years of spare parts availability, make a Liebherr appliance a robust, reliable, and extremely long-lasting top performer in demanding everyday work.

Easy to clean interior

The plastic inside container is made of polystyrene: a fully recyclable, robust, and odourless plastic. Manufactured seamlessly from one piece, it has no hidden dirt traps and the large corner radii can be cleaned quickly and easily. The perfect combination of sustainability and hygiene.

Alarm relay

In the event of an alarm, the responsible control centre is informed immediately, usually through connection to the building control system. You can define in advance which alarms are to be forwarded, as well as set how long the forwarding remains active and whether a reminder should be sent after the alarm acknowledgement. This allows you to react immediately in critical situations.

15 years of spare parts availability

Liebherr-Hausgeräte GmbH is taking the service life of its high-quality appliances one step further for its customers: Spare parts availability will be extended to 15 years from the end of production of the respective model. This applies to all functional parts and storable parts of the equipment. Liebherr-Hausgeräte also guarantees this service retroactively for all appliances produced since 1 January 2021.

Height-adjustable feet

With height-adjustable feet as an accessory, the height of the appliance can be adjusted to your needs. For example, you could raise your professional appliance to clean under it more easily.

Alarm history

In order to be able to evaluate the quality of the stored substances, a clear history of anomalies that have occurred is necessary. The alarm history records important data about the last ten alarms such as date, duration or maximum temperature. This way, you don't rely on your memory to perform the check but rather rely on the facts.

Alarm test

An alarm is only ever any good if it can be triggered. The alarm test can be used to check the functionality of the internal and possibly an externally connected alarm device. The cooling of the appliance is not interrupted during the test run, so you can arrange an emergency simulation and rehearse with your team as you please.

Antibacterial lever handle

A benefit for users but a bane for germs: The easy-turn handle mechanism makes opening the door effortless. It contains special antimicrobial substances that reduce bacteria by up to 99.99%*. Regular and time-consuming disinfection is not necessary. This means the appliance is extremely safe even if many people have access to it. *According to ISO 22196:2011

Calibration function

Due to operational requirements and application-specific conditions, it is possible to deviate the temperature of the interior from the set temperature to a storage temperature determined with calibrated thermometers. These deviations can be adjusted by the calibration function. For the secure feeling of cooling at precise temperatures.

Interchangeable door hinge

Liebherr appliances are fitted with a right-hand door hinge as standard. Without much effort – and without any additional parts – the door hinge can be changed to the left. This allows you maximum flexibility when choosing your installation location.

Replaceable door seal

Save time and money: Liebherr's plug-in door seals can be easily replaced. If a seal is damaged, you can replace it yourself without any tools.

Cleanroom compatible

Liebherr fridges and freezers in the new scientific line have been tested for use in cleanrooms in accordance with DIN EN ISO 14644. As a result, an additional risk assessment by the customer to determine cleanroom suitability is no longer necessary. This saves time and money.

Clear appliance information

All information about the appliance should be there exactly when you need it. That's why every Liebherr has its serial and service number as well as the model designation on the display, where it can be easilyy read. Frustrated searches or even having to clear the interior to be able to read off the important codes are now a thing of the past.

Demo mode

For training purposes or exhibitions, the functionalities of the appliance can be simulated in demo mode without having to operate the appliance. This saves time and money as the cooling function is not needed.

Evaporator cover

The evaporator is secured with a cover to prevent stored substances from coming into contact with its cold surface. This means that it is impossible for substances to accidentally freeze on its surface. In addition, the evaporator cover ensures even greater temperature stability.

Feedthrough for external sensors

To additionally control the storage temperature with the help of a separate sensor, wiring from the outside to the inside is required. The cable feeding offers a clean and professional solution here. The integrated opening allows connection without drilling holes or breaking the door seal.

Hidden customer menu

Protected, secure, simple: The hidden customer menu provides users with status information about the appliance or allows them to make detailed appliance settings, such as resetting to factory settings. Since this information and the settings are located on a separate, code-protected menu level, unwanted changes or manipulation are avoided.

Hidden technician menu

The hidden service menu allows individual configuration of the appliance, such as alarm sound on/off, adjustment of target value ranges or changes to automatic defrosting. By making technical fine adjustments, the appliance can be adapted to your specific needs.

Integrated data logger

To ensure full traceability independent of the monitoring systems, the integrated data logger records the temperature profile, alarm history, and service information for up to five years. The stored data can be read out directly on the appliance via a USB interface.

Intuitive menu navigation

Self-explanatory, convenient, and clear: Seamlessly integrated into the door, the control panel shows detailed appliance information and your current appliance status on a generous display, which is colour-coded depending on the topic. The menu navigation is self-explanatory and is controlled by “touch and slide”.

LED front lighting

Min./max. temperature recording

Always keep an eye on the temperature: Min./max. temperature recording stores the minimum and maximum temperature values of the interior that have occurred from a defined start time and shows them clearly in the display. This way you can be sure that, up until the moment you read off the values, the storage temperatures were always within the tolerated limits.

Almost maintenance free

Saves time, energy, and money: Liebherr’s professional freestanding appliances operate without filters or other components and parts that require regular replacement. Only cleaning and calibration in line with your individual needs are necessary on a regular basis.

IEC 61010-2-011 Standard

Liebherr refrigerators and freezers specially developed for storing temperature-sensitive products are CE safety-compliant. This ensures that all mechanical and electrical requirements for injury-free operation are met – and that you and your team are kept safe.

Power failure alarm

If a malfunction occurs, an integrated battery provides a visual and audible alarm and takes over the power supply. As soon as the power is restored, the time of failure and the maximum temperature reached are displayed.

Product sensor PT1000

In addition to the integrated control sensor, another separate sensor can be connected to measure a simulated product temperature. The product sensor temperature shown in the display can be calibrated independently, instrument alarms and min./max. limits refer to this value. For greater storage reliability based on real product values.

Quick start guide

No one likes to read the instructions. That's why Liebherr offers the most important information at a glance on two pages. This includes information on menu navigation, the electronic lock, cleaning, and general topics such as stored goods that are or are not permitted. Leave the technician in charge of reading the original manual.

Recommended cleaning products and disinfectant

Liebherr appliances are designed to have a product lifetime of 15 years. To maintain this, cleaning and disinfecting agents that have been tested by Liebherr for safe use are recommended separately, or in the manual. This way you can be sure that you are not harming your appliance by mistake when you are actually trying to take care of it.

Reminder function

The reminder function reminds you when the next basic cleaning or calibration is due. The interval can be selected from predefined intervals and set directly on the appliance. Leaving you to focus solely on your valuable work.

Self-closing door < 90°

Carry out routine work in comfort; safety back-up in case anything is missed: From an opening angle of approx. 90°, the appliance door remains open and facilitates loading and unloading as well as cleaning. Below approx. 90°, it closes by itself so that the appliance does not accidentally stand open. This keeps the temperature stable and preserves the quality of your stored substances.

Settings with password protection

All settings that influence the function or control of the appliance can be secured by password. This means that the contents are optimally protected from unwanted changes or manipulation to the storage conditions.

Side-by-side set

The accessory kit provides a neat and secure solution for lining up multiple appliances. The units are firmly connected to each other via a profile rail so that they form a seamless front and cannot slip. Fixing them also guarantees the recommended distance and prevents condensation building up between the appliances.

Sturdy castors

With retrofittable castors, professional equipment for storing temperature-sensitive products remains extremely mobile. This allows you to change the installation location at any time or simply move the appliance for easier cleaning.
