The Blizzard™ NU-99486 17.1 Cubic Feet (486-Liter) -86 °C Ultralow Freezer (ULT) from NuAire provides core standard features and reliable performance for the storage of storage of cancer cells, stem cells, cord blood, T-cells, organ/tissue and other samples.


Blizzard™ Ultralow Temperature Freezers provide stable storage conditions for your samples and offer advanced features at an affordable price. Vacuum insulated panels surround the storage chamber to provide greater temperature uniformity and maximize storage space. A dual compressor system dependably maintains consistent storage conditions. Blizzard™ Ultralow Temperature Freezers are the safer choice for your storage needs.

Design and Technology

Power Factor Control

Monitors, compensates, and protects against facility line voltage variations.

Four Internal Shelf Locations (Three Adjustable / One Stationary)

Provides flexibility in rack configurations.

HFC Refrigerants

Commercially available HFC refrigerants are efficient, environmentally safe, and non-ozone depleting.

Vacuum Insulated Panels (VIP)

Surround the storage chamber offering increased temperature stability and maximizing interior volume.

Remote Alarm Contacts

RS 232 and RS 485 provide connection ports for popular monitoring systems.

Battery Backup

Powers the freezer in the event of an interruption in the primary power source. In the event of a power failure, the battery backup will power electronics and alarm systems.

Front Filter Access

Allows convenient access for regular maintenance to the washable condenser filter.

Outer Door Claw Latch

Maintains a tight seal to minimize frost built-up, yet requires minimal effort to open the freezer door.

Removable Insulated Inner Doors

Gasket sealed inner doors allow access to selected samples while preventing frost build-up and thermal intrusion in other parts of the interior.

Multi-point Gasket System

Four gaskets located on the outer door and one gasket on each inner door protects against thermal intrusion.

A USB Port

Easily accessible from the front of the freezer to download data.

Pressure Equalization Port

The Pressure Equalization Port is heated with a spring assisted mechanism to prevent icing allowing the freezer door to be opened shortly after adding samples.

Sample Ports

Two sample ports are located on the back top and bottom of the freezer to allow convenient access for monitoring tools.

Circular Chart Recorder

A circular chart recorder (optional) can be front-mounted for independent temperature recording and monitoring.
