  • Equipped with NuveCom™ communication unit.
  • Minimized air exchange on opening reduces ice build-up and protects samples.


The ultimate protection for your samples is ensured by placing the cooling coils inside the shelves to provide the most efficient heat extraction. No reliance on air convection to transfer energy to the walls of the freezer but transfer by conduction with DirectFREEZE™.

When the DF series are used according to instructions, occasionally wiping away the ‘snow’, no ice will form on the door, maintaining efficient cooling.

The chamber of the DF series is designed around the sizes of the most commonly used cryoboxes that account for over 80% of all usage. This means that the maximum numbers of samples are stored in the minimum footprint.

The DF series Ultra Low Temperature Freezers are powered by N-SmArt™ which has internal memory storing temperatures records up to ten years with one hour intervals as digitally and graphically. By means of NuveCloser™ software, The DF series can be controlled via internet. Sample safety is given top priority with audible and visual alarm system and optional NuveWarn™ remote alarm system, plus an optional AlerText™ text message to multiple mobile phones.
