Liebherr Laboratory Freezer SFF Series
with plastic inner container
Min./max. temperature recording
The min/max temperature recording stores the minimum and maximum values of the interior and shows in the display whether the storage temperatures were within the tolerance limits.
+2-°C-SafetyDevice
If the temperature drops below +2 °C in the event of a malfunction, the SafetyDevice takes over control. It stabilizes the temperature, activates the alarm and protects the contents from freezing.
Power failure alarm
An integrated battery provides a visual and audible alarm in the event of a failure and takes over the power supply. As soon as power is restored, the time of failure and maximum temperature reached are displayed.
LightAlarm
In the event of an uncontrolled temperature rise or other problems, the interior light of the unit starts to flash. This quickly indicates the need for action.
Feed-through for external sensors
An integrated opening allows a separate sensor to be connected for additional temperature control without having to drill holes or break the door seal.
Integrated data logger
The integrated logger records temperature profile, alarm history and service information for up to five years. The data can be read directly from the unit via USB interface.
Mechanical lock
Professional Liebherr units are equipped with a mechanical lock and two keys. This ensures that unauthorized persons cannot access your valuable and sensitive stored goods.
SmartMonitoring
The cloud-based, digital solution continuously monitors and documents temperatures and immediately alerts you by email, SMS or phone call in case of deviations.
Integrated WiFi/LAN interface
The integrated WiFi/LAN interface allows you to effortlessly network your equipment with Liebherr's SmartMonitoring or connect it to local existing systems.
Easy to clean interior
The interior container made of fully recyclable, robust and odorless polystyrene is manufactured in one piece without joints. This makes it quick and easy to clean in large radii.
Replaceable door seal
Save time and money: Liebherr's plug-in door seals are easily replaced. If a seal is damaged, you can replace it yourself without any tools at all.
Self-closing door <90°.
To make loading, unloading and cleaning easier for you, the appliance door remains open from an opening angle of approx. 90°, below which it closes by itself for safety.
Note: The equipment details shown depend on the model; the description for the respective model applies.
