MDF-U74V VIP ULT Freezers VIP ULT Freezers PHCBi -80ˇăC/-86ˇăC ULT Freezer Ultra Low Temperature Freezer

Extra-Large Capacity, 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 circuit regulates high stage compressor ON- OFF cycles, resulting in a reduction in energy consumption of approx. 14%* compared to the previous model. *The data is a measured example (AT 23˚C, 230V 50Hz, no load). Actual power consumption will vary depending on set and ambient conditions, loading and local voltage.
  • 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 (Condition monitor) monitors ambient and system conditions continuously and notifies of any abnormalities before a problem happens.

  • 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.

  • Alarm lamp and buzzer offer secure warning of power failure or abnormal temperature increase.
  • High and low temperature warning provides an audible and visual alarm when the temperature deviates more than ±5˚C to ±20˚C (adjustable) from the set point.
  • Alarm ring-back function ensures the buzzer will resume operation, should alarm conditions continue after it is silenced.
  • Microprocessor-controlled blocked filter alarm protects the refrigeration circuit.
  • The rugged, one-handed outer door latch allows a padlock to be used to securely protect valuable samples.
  • Control panel with digital display for easy operation.
  • A battery and fan motor replacement notification is provided.

*Cooling performance is indicated by the temperature reached at the center of the freezer (at ambient temperature of 30°C with no load). In order to use the freezer at a stable temperature for a long time, it is recommended that the temperature be set to at least 5°C higher than the indicated lowest temperature.

In addition, depending on the usage conditions, it may not be possible to reach the indicated lowest temperature.
