Liebherr SFFsg laboratory freezers

Constant temperatures are essential when storing sensitive substances. This especially applies to work in laboratories, where even the slightest deviations can jeopardise the quality of research results. This is why Liebherr has developed new refrigerators and freezers specifically for this sector, combining maximum refrigeration performance with optimum temperature stability. Innovative safety features with monitoring and alarm functions offer all-round protection from all kinds of incident and malfunction.


% Liebherr SFFsg 5501 laboratory freezer Liebherr freezers for laboratory and research use also meet the highest requirements, especially in terms of safety and temperature stability. • Min./max. temperature log The min./max. temperature log stores the minimum and maximum interior temperatures and shows on the display whether the storage temperatures were within the tolerance limits. • +2 °C SafetyDevice If the temperature falls below +2 °C due to a malfunction, the SafetyDevice takes control, stabilising the temperature, activating the alarm and protecting the contents from freezing • Power failure alarm Network failure alarm after a power failure. • Feedthrough for external sensors An integrated opening allows a separate sensor to be connected for additional temperature monitoring without having to drill holes or break the door seal. • Mechanical lock Liebherr professional appliances are equipped with a mechanical lock and two keys. This ensures that unauthorised persons cannot access your valuable and sensitive stored goods. • 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. • WiFi/LAN interface (optional) The integrated WiFi/LAN interface enables you to easily connect your appliances with Liebherr SmartMonitoring or existing local systems. • Easy-to-clean interior The inner liner made of fully recyclable, robust and odourless polystyrene is manufactured in one piece without joints. This makes it quick and easy to clean the large, rounded corners. • Replaceable door seal Save time and money: the insertable Liebherr door seals are easy to change. If a seal is damaged, you can replace it yourself without any tools. Contact Liebherr Customer Service to purchase replacements. • Self-closing door < 90° To make loading, unloading and cleaning easier, the appliance door stays open if opened by more than 90°. If the opening angle is less than 90°, it closes automatically for safety • SmartFrost technology Thanks to the SmartFrost technology, the frosting of the interior and stored products is significantly reduced. Defrosting is required less often – and if it is, it is made much easier by the smooth, easy-to-clean inner walls. The evaporator foamed into the insulation ensures high energy efficiency and uniform cooling. • ±5 °C temperature stability Sensitive substances cannot be subjected to large deviations from the set storage temperature. Liebherr freezers guarantee a temperature fluctuation of no more than ±5 °C, so that the valuable goods you store in them are optimally protected and their quality is preserved. • Standard compliance The devices fully comply with the DIN 13277 standard and the IEC 61010-2-011 standard.	% Liebherr SFFsg 4001 laboratory freezer Liebherr freezers for laboratory and research use also meet the highest requirements, especially in terms of safety and temperature stability. • Min./max. temperature log The min./max. temperature log stores the minimum and maximum interior temperatures and shows on the display whether the storage temperatures were within the tolerance limits. • +2 °C SafetyDevice If the temperature falls below +2 °C due to a malfunction, the SafetyDevice takes control, stabilising the temperature, activating the alarm and protecting the contents from freezing • Power failure alarm Network failure alarm after a power failure. • Feedthrough for external sensors An integrated opening allows a separate sensor to be connected for additional temperature monitoring without having to drill holes or break the door seal. • Mechanical lock Liebherr professional appliances are equipped with a mechanical lock and two keys.
