The Haier DW-86L828BPST is a TwinCool -86°C ultra-low freezer built around two fully independent hydrocarbon refrigeration systems, each able to maintain -80°C on its own. That redundancy is the reason to specify this model: if one circuit is serviced or fails, the second continues protecting 828 L (29.2 cu ft) of irreplaceable samples. Frequency-conversion compressors and an LCD touchscreen deliver a claimed 50% energy reduction versus traditional HFC systems, making the DW-86L828BPST a first-choice cabinet for biorepositories that cannot tolerate a single point of failure.

Application Profile
The DW-86L828BPST answers the single hardest question in cold-chain risk management: what happens when a compressor fails at 2 a.m.? Its double independent hydrocarbon circuits are engineered so that either system alone can hold the cabinet at -80°C, converting a potential catastrophic loss into a serviceable event with no sample warming. This is the model to specify for master cell banks, clinical-trial specimens and long-accrued biobank inventory where the replacement cost of the contents dwarfs the freezer itself.
Redundancy does not come at the expense of efficiency. Intelligent frequency-conversion technology combined with the 100% HC refrigeration system delivers up to a 50% reduction in energy usage compared with traditional HFC freezers, and the cabinet runs at just 42 dB(A). Four insulated inner doors and three adjustable stainless-steel shelves compartmentalize the 828 L volume into 600 2-inch-box capacity, while optional LN₂ or CO₂ backup adds a further layer of protection during a total power outage.
Frequently Asked Questions
What makes the DW-86L828BPST "TwinCool"? It carries two fully independent hydrocarbon refrigeration systems. Each can maintain -80°C by itself, so the failure or servicing of one circuit does not warm the stored samples.
What temperature range does it reach? -40°C to -86°C, with a cooling performance of -86°C.
How much can it store? 828 L (29.2 cu ft), roughly 600 standard 2-inch cryoboxes, across four inner doors and three adjustable stainless-steel shelves.
Is it energy efficient despite having two systems? Yes. Frequency-conversion compressors plus hydrocarbon refrigerant give a claimed 50% energy reduction versus traditional HFC systems, and it is UL / ENERGY STAR listed.
What power supply does it need? This configuration is specified at 110-230V/60Hz; the platform is rated for 100-230V/50-60Hz universal input.
Ordering & Configuration
The DW-86L828BPST is a capital purchase. Add it to a quote and a Legacy Lab Supplies specialist will confirm freight, delivery access, electrical service and optional backup systems before order, and route factory warranty registration. Lead time is quoted per configuration; contact us for current availability.
Specify the DW-86L828BPST when refrigeration redundancy is non-negotiable — dual independent systems make it the safest choice in Haier's -86°C line for high-value biorepositories. If a single-circuit variable-speed freezer meets your risk tolerance at lower cost, compare the DW-86L830BPT; for smaller footprints, step down to the DW-86L728JA.
