FAQs
How does the +2°C SafetyDevice work?
The +2°C SafetyDevice takes control if the temperature drops below +2°C in the event of an incident. It stabilizes the temperature, activates the alarm and protects the contents from freezing.
What happens in the event of a power failure?
The power failure info reports when the appliance was temporarily without power and what the maximum temperature was. This allows you to better assess the potential loss of quality.
How is the temperature monitored?
The appliance has a min/max temperature recording function that saves the minimum and maximum values of the interior and shows on the display whether the storage temperatures were within the tolerance limits.
Can I connect external sensors?
Yes, the appliance has an integrated opening that allows you to connect a separate sensor for additional temperature control without having to drill holes or break the door seal.
Conclusion
The Liebherr SRFfg laboratory refrigeration unit with ATEX 95 offers a safe and reliable solution for the storage of explosive and highly flammable materials in laboratories and commercial environments. With its numerous functions and certifications, it ensures that your valuable and sensitive substances are optimally protected. Similar models such as the Liebherr HMFvh medicine cooler in accordance with DIN 13277 also offer high safety standards and could be a suitable alternative.
