Frequently Asked Questions About the Axofreeze MF-86V838TDV
How does the redundancy in the dual cooling system work?
The system operates with two completely independent cooling circuits, each equipped with its own compressor. In normal operation, both circuits share the load, which increases efficiency. Should one circuit fail, the second automatically takes over full cooling capacity and keeps the temperature stable at -80°C. This provides double protection for highly sensitive sample materials.
What advantages do the VIP+ insulation and HC refrigerants offer?
The 90 mm thick VIP+ vacuum insulation massively reduces heat ingress from outside compared to standard insulation, which lowers power consumption. Combined with natural hydrocarbon refrigerants (HC), a GWP value of zero is achieved. This protects the environment and makes operation of the ultra-low temperature freezer particularly sustainable. In addition, the warm-up time during a power outage is significantly extended.
How is complete documentation of storage conditions ensured?
Control is performed via a 10.1-inch touchscreen, which visualizes all relevant data and stores it via a USB interface for up to 10 years. An integrated battery maintains the display and alarm system for approximately 48 hours during a power outage. The device can also be integrated directly into a central laboratory monitoring network via the RS485 interface. Alarms are reported visually, acoustically, and via remote contact.
