Compliance with the ATEX Directive

Liebherr laboratory equipment conforms to EN/IEC 60079-0 or EN-IEC 60079-7 and complies with EU Directive 2014/34/EU (“ATEX Directive”). Classification of the interior to <Ex> II 3 G Ex ec IIC T6 (declared as Zone 22) makes them suitable for flammable substances in closed containers that could form explosive atmospheres.

SmartFrost

SmartFrost reduces frost build-up in the interior and on stored products. Defrosting is required less often – and when it is necessary, it is made much easier by the smooth, easy-to-clean interior walls. The evaporator in the foam insulation ensures high levels of energy efficiency as well as even cooling.

±5 °C temperature stability

Sensitive substances cannot be subjected to large deviations from the set storage temperature. Liebherr freezers guarantee a minimal temperature fluctuation of no more than ±5 °C. This means that your valuable contents are optimally protected against impairment and their quality is preserved.

Compliance with the ATEX Directive

SmartFrost

Retrofittable WiFi/LAN interface

This is how easy it is to network a Liebherr: With the retrofittable WiFi and LAN interface, appliances can be effortlessly connected to external systems, such as SmartMonitoring from Liebherr. With the digital monitoring solution, the storage temperature is controlled and documented conveniently and securely via the subsequently set up interface.

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.

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

Intuitive menu navigation

Convenience at your fingertips: Read out the appliance status from the control panel integrated flush in the door without needing to open it. The menu guidance is self-explanatory and controlled by three touch buttons.

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.

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.

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.

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.

Connection frame

Odour or temperature separation can be achieved courtesy of the white connection frame, which makes it possible to combine various fridges yet still maintain a small footprint.

Worktop

Benefit from a larger work surface thanks to a robust worktop that is heat resistant up to 100 °C. This optional worktop, available as an accessory, is easy to install and raises your appliance by 3 cm so that it fits perfectly with 85-cm work tables. The integrated ventilation slits ensure excellent heat dissipation, even when installed flush to the wall.

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.

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.

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.

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.

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 info

If the power supply has been interrupted due to a fault, the power failure info appears when the power is restored. This reports that the appliance was temporarily without power and details which maximum temperature was reached during this time. This allows you to assess whether a loss of quality is to be expected due to the power failure.

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.

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.
