Blizzard HCNU-99728J
-80°C Ultralow Freezer
ENERGY EFFICIENT HC REFRIGERANTS | VIP & POLYURETHANE FOAM INSULATED | INSULATED & GASKETED INNER DOORS | USB DOWNLOADABLE DATA LOGGING
The Blizzard™ range of vertical ultra-low freezers efficiently stores samples by using HC refrigerants and protects them within a structure using steel walls and a composite VIP and polyurethane insulation. Multiple, polyurethane foam insulated interior doors allow easy access with minimal temperature loss to racks set on the stainless-steel shelves inside. Running parameters are clearly displayed on the front electronic control panel at all times and can be downloaded via the USB port for long term datalogging.

A MULTI-LAYERED DEFENSE AGAINST TEMPERATURE LOSS.
INSULATED CHAMBER AND LOSS
A combination of polyurethane and VIP insulation in the main body of the freezer forms the first line of defense for the low temperature environment.
The outer door uses a quadruple gasket to defend against loss of cold air at this critical juncture and closes with a claw-like latch to ensure a tight fit.
The final gatekeepers for the samples inside, the segmented inner doors are themselves both insulated and single-gasketed to minimize loss of cold air.
Stainless steel shelves allow racks to be aligned with the segmented doors for quick access to needed samples without exposing other compartments.
