Ultra Slim, Space Saving Ultra-Low Freezer with Improved Energy Consumption

Evolutionary design
  • Panasonic V.I.P. Series -86˚C ultra-low temperature freezers use patented revolutionary vacuum insulation cabinet construction that reduces the wall thickness from 14cm to 7cm (5.5” to 2.7”) and achieves up to 30% more storage capacity than conventionally insulated freezers, without increasing its footprint.

  • The newly developed refrigeration system and the freezer structure offer a quiet experimental environment.

  • Achieves 12% higher energy conservation than previous model. (115V, 60Hz)

  • The rear ventilation cover combines with the aerodynamically designed and positioned components in the refrigeration compartment to provide superior air flow, drastically reducing the load on the freezer and contributing to improved durability.

  • Two independent and insulated inner doors with gaskets prevent cold air leakage.

Status Alert : Unconventional operation can cause malfunctions. Function control monitor notifies the unconventional operation to prevent the problems and helps the safe operation.
It always monitors the operation, and the flash lamp notifies the drops in the voltage, an abnormality of the temperature rise when the ambient temp is over 35˚C, lower than approximately 0˚C,and overload operation. It also notifies the time of battery replacement, and the door status.
The status of these alarms and indicators will be shown on the control panel.
*Pressing the Status key will display the status alert condition reference number.

  • A beak style inner door latch tightly closes the inner door against the freezer frame. It also helps make opening and closing the door smoother.
  • The condenser filter is situated at the bottom right side of the front panel to make filter removal and cleaning easier.
