Liebherr Laboratory Cooling Unit SRFfg Performance Series with ATEX 95
with explosion-proof interior
Explosion protection: ATEX 95
ATEX 95 certification certifies that Liebherr's laboratory refrigerators and freezers with explosion protection are suitable for the storage of explosive and highly flammable materials as defined by EU Directive 2014/34/EU (ATEX).
+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 info
The power failure info reports when the device was temporarily without power and what the maximum temperature was during this time. This allows you to better assess the potential loss of quality.
Min./max. temperature recording
The min/max temperature recording stores the minimum and maximum values of the interior and shows on the display whether the storage temperatures were within the tolerance limits.
Easy-to-clean interior
The inner chamber is made of fully recyclable, robust and odorless polystyrene and is manufactured in one piece without joints. This makes it quick and easy to clean in large radii.
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.
Mechanical lock
Professional Liebherr appliances 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.
Retrofittable WiFi/LAN interface
The retrofittable WiFi/LAN interface allows you to effortlessly network your devices with Liebherr's SmartMonitoring or connect them to local existing systems.
Antimicrobial handle with opening mechanism
The smooth-running handle is infused with special antimicrobial substances, making it particularly hygienic. Regular and time-consuming disinfection becomes unnecessary.
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.
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.
