SRFfg 4001 Performance with drawers

Liebherr laboratory refrigerators and freezers, including the SRFfg 4001, have to meet the highest criteria in terms of security and reliability. Precise electronic controls, a forced-air cooling system and highly effective insulation work together to ensure outstanding energy efficiency, so that operating costs are low and the environment is protected. Advanced components and precision controls ensure that substances and materials are stored as optimally as possible.

SRFfg 4001 Performance overview

• ±3 °C temperature stability: Temperature fluctuations must be minimal to ensure that the quality of sensitive substances is preserved. Liebherr refrigerators have an impressive maximum deviation of just ±3 °C from the set temperature. This not only maintains the storage climate, but also the value of your stored goods.
• 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.
• +2 °C SafetyDevice: If the temperature in the appliance drops below +2 °C due to a malfunction, the +2 °C SafetyDevice function takes control, which keeps the temperature stable and activates an alarm. Sensitive substances are protected from freezing and you are notified immediately.
• 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.
• 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.
• Environmentally friendly refrigerants: Liebherr appliances are optimised for maximum energy efficiency and low operating costs. We only use the natural and environmentally-friendly refrigerants R 600a and R 290. When used with highly efficient compressors, these are extraordinarily efficient and, with their low global warming potential, also future-proof.
