The Haier DW-86L728JA is a large-capacity, -86°C upright ultra-low freezer offering 728 L (25.7 cu ft), roughly 500 standard 2-inch cryoboxes, on a 208-230V/60Hz supply. Built on Haier Biomedical's energy-efficient hydrocarbon cascade platform, it pairs high sample density with four insulated inner doors for controlled access, making it a strong central freezer for biobanks and multi-group core facilities that have outgrown mid-size cabinets.

Application Profile
At 728 L, the DW-86L728JA is a central-freezer class cabinet, the unit a facility standardizes on when several research groups pool their -80°C storage. Three adjustable stainless-steel shelves and four insulated inner doors divide the volume into manageable zones, so a technician retrieving one group's samples exposes only a quarter of the load. That compartmentalization is the practical mechanism that protects the -40°C to -86°C stability of high-value inventory during frequent, everyday access.
The hydrocarbon cascade refrigeration uses a zero-GWP HC refrigerant and reaches a true -86°C. The unit carries the complete Haier alarm suite plus USB and remote-alarm outputs for integration into building monitoring, and accepts optional LN₂ or CO₂ backup for outage protection. It runs on a 208-230V/60Hz circuit at up to 1700 W, so confirm a suitable dedicated receptacle and heat-rejection headroom at the install site.
Frequently Asked Questions
How much can the DW-86L728JA store? 728 L (25.7 cu ft), up to 500 standard 2-inch cryoboxes, across three adjustable stainless-steel shelves and four inner doors.
What temperature does it reach? It reaches -86°C (operating range -40°C to -86°C) with Haier's hydrocarbon cascade refrigeration.
What power does it require? A 208-230V/60Hz supply (listed as 220V/60Hz), drawing up to 1700 W. Plan a dedicated receptacle.
Does it protect samples during outages? The full alarm suite runs on backup, and optional LN₂ or CO₂ backup systems can hold temperature during a power failure.
Is it ENERGY STAR rated? It uses Haier's energy-efficient hydrocarbon refrigeration and is UL listed. An ENERGY STAR rating for the 728JA is not confirmed in the current brochure spec table. Contact us if ENERGY STAR qualification is a procurement requirement.
Ordering & Configuration
The DW-86L728JA is a capital purchase. Add it to a quote and a Legacy Lab Supplies specialist will confirm the 208-230V receptacle, delivery access and any LN₂/CO₂ backup options before order, and route factory warranty registration. Lead time is quoted per configuration; contact us for current availability.
Choose the DW-86L728JA as a high-density central -86°C freezer when you need ~500-box capacity with four-door access control. Step down to the 115V DW-86L578J for easier siting at 400 boxes, or up to the variable-speed DW-86L830BPT for the largest capacity and lowest running cost.
