-86°C Ultralow Freezer

For laboratories managing growing sample collections, the Blizzard VFT NU-99729VFT -86°C Ultralow Temperature Freezer provides a nominal 729-liter (25.7 cu. ft.) internal volume of ultralow temperature storage — accommodating up to 50,000 two-milliliter vials across 20 racks. It is the most widely specified model in the Blizzard VFT Series, combining meaningful capacity with ENERGY STAR-certified efficiency. Variable Frequency Technology (VFT) continuously modulates compressor speed to match real-time thermal demand, achieving ENERGY STAR-certified performance at 8.1 kWh per day. Two selectable operating modes allow your team to adapt to the moment: High Performance mode for tightest temperature uniformity, or Energy Saving mode for reduced power consumption during stable, long-term archiving. Four independent inner door sections minimize thermal disturbance during sample access, isolating each retrieval event to a single compartment while the remaining three maintain stable conditions. A 22-hour battery backup system sustains alarm coverage — monitoring temperature, power status, door position, probe integrity, condenser condition, and battery state — throughout power disruptions.

Variable Frequency Technology adapts compressor output in real time, achieving ENERGY STAR-certified energy consumption of 8.1 kWh per day. High Performance and Energy Saving modes allow your team to optimize for temperature control or energy economy.

Four thermally isolated inner door compartments concentrate thermal disturbance on the zone being accessed, keeping the remaining sample inventory undisturbed, essential in laboratories with frequent retrieval activity.

22-hour battery-backed alarm coverage maintains monitoring of temperature, power status, door position, probe integrity, condenser condition, and battery state during power events — protecting the samples your research depends on.

R290/R170 hydrocarbon refrigerant combines effective thermodynamic performance with near-zero global warming potential — supporting current environmental compliance requirements and positioning labs for anticipated future refrigerant standards.
