Choosing a -80°C Laboratory Deep Freezer: Dual, Cascade or Self-Cascade
The refrigeration system decides what happens when a compressor fails, how much power the freezer draws and which sizes are available. Our ULT freezer buying guide compares them in detail.
- Dual-system -86°C freezers → Two independent refrigeration systems; if one fails, the other holds the cabinet at -70°C. 408L to 838L.
- Cascade -86°C freezers → Two-stage cascade refrigeration with HC refrigerant. 340L to 838L.
- Self-cascade -86°C freezers → Single compressor with mixed refrigerant. 58L under-counter to 408L.

ULT Freezer FAQs
What is an ultra low temperature freezer?
An ultra low temperature (ULT) freezer is a laboratory freezer that reaches about -80°C or colder. WinHyCare ULT freezers are adjustable from -40°C to -86°C in 1°C steps and are used for biological samples, reagents, enzymes, tissue and frozen blood components.
What is the difference between a -80°C freezer and a -86°C freezer?
They are usually the same equipment. -86°C is the lowest temperature the freezer can reach; -80°C is the typical working set point. The margin below the set point helps the cabinet recover after door openings. Our ULT buying guide covers set-point choice and energy use.
Should I buy a dual-system, cascade or self-cascade ULT freezer?
Dual-system models suit collections where a single compressor failure is unacceptable, because the second system holds -70°C. Cascade models cover the large-capacity range. Self-cascade models use one compressor and include the compact 58L under-counter unit and the lowest-energy model in our range (WDF-86V408E, 12.82 kWh/24h).
What capacities are available?
From the 58L under-counter WDF-86V58 to 838L upright cabinets. New-Generation models list storage in 2-inch boxes, from 192 boxes (340L) to 600 boxes (838L).
Do the freezers keep temperature records?
Yes. Models have USB temperature-data download, high/low temperature and power-failure alarms with battery backup, and remote alarm contacts on many models, so logs can be archived for audits.
What is the price of a ULT freezer?
We quote per model, quantity and delivery city, including installation and optional annual maintenance. Send the capacity and configuration you need.
