Overview
The MDF-DU703VHE-PE VIP SMART Ultra-Low Temperature Freezer combines energy-efficient sample storage with advanced access control and reliable temperature performance. Effective capacity: 729 liter. Cooling performance range: -86 to -40 °C. Natural refrigerants and inverter compressor technology improve efficiency while maintaining cooling performance, ambient tolerance and recovery following door openings.

Energy-saving performance
Designed to reduce operating costs associated with ultra-low temperature storage and deliver low energy consumption while maintaining reliable performance.

• 5.4 kWh/day at -80°C
• 4.4 kWh/day at -70°C

Smart Performance
Inverter-driven compressors with SMART control provide excellent temperature uniformity and intelligent compressor management to maintain tight temperature stability while improving efficiency.

Security control and monitoring
Manage and monitor access to stored samples, track who accessed the freezer and when, and measure door-open duration. Multiple access-control methods are available:

• Facial recognition (optional)
• Keypad
• Proximity card / NFC (optional)
