Product features

• 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.

• 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.

• 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.

• 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.

• 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.

• 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

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• SmartMonitoring (optional)
The cloud-based digital solution continuously monitors and documents temperatures and alerts you immediately via email, text message or phone if any deviations occur
