Frequently Asked Questions
How does the energy consumption of the MDF-U781VHE compare to older models?
The ALPHAVITA MDF-U781VHE consumes only 8.7 kWh per 24 hours thanks to frequency-controlled inverter compressors. The VIP insulation (Vacuum Insulation Panel) achieves 13 times better thermal insulation performance than conventional PU foams at a reduced wall thickness of 70 mm. Compared to older Sanyo or Panasonic models without inverter technology, this saves up to 30% in operating costs. The cascade cooling with HC refrigerant additionally optimizes the energy balance while delivering maximum cooling performance.
What safety features does the ultra-low temperature freezer offer for valuable samples?
The MDF-U781VHE features a multi-layered safety concept: electronic door access via PIN code, RFID card, or fingerprint prevents unauthorized access. The integrated data logger records all temperature data for USB export. Comprehensive alarm functions (visual, audible, remote alarm via volt-free contact) warn of over-/under-temperature, power failure, sensor errors, open door, and high condenser temperature. Two inner doors and a pressure equalization valve minimize temperature loss when opening.
Is the unit compatible with standard cryoboxes and existing storage systems?
Yes, the MDF-U781VHE provides space for 528 standard cryoboxes in 2-inch format, distributed across 24 racks. The three removable stainless steel shelves (871 × 537 mm) have a load capacity of up to 50 kg and are compatible with common freezer rack systems. The interior layout with four compartments allows flexible organization of various sample collections. Two cable ports (17 mm) allow for integration of external temperature monitors. The ergonomic design on sturdy casters facilitates positioning and cleaning in the laboratory.
