The Haier DW-86L578JA is a single-system −86°C upright ultra-low freezer that delivers full 578 L (20.4 cu ft) biobank capacity at a lower entry price than the variable-speed BPT/BPST models. A high-efficiency hydrocarbon compressor reaches −86°C on a 220V circuit, four insulated inner doors and three adjustable stainless shelves organize up to 400 two-inch boxes, and the cabinet is UL certified.

Application Profile
The DW-86L578JA is the workhorse −86°C upright: a standard 20.4 cu ft cabinet for core biobanking, cell-line archives, nucleic-acid and protein storage, and clinical specimen inventories where a proven single-refrigeration-system freezer at competitive cost is the right call. It reaches a genuine −86°C (−40°C to −86°C range) with a high-efficiency HC compressor and delivers the same 400-box interior organization as its frequency-conversion siblings.
Four insulated inner doors divide the cabinet so opening one compartment barely disturbs the other three, and three adjustable stainless shelves let you match shelf pitch to your rack heights. Two rear 25 mm portholes accept independent monitoring probes, and casters plus leveling feet ease placement and validation.
Design Architecture
The microprocessor controller with LED display drives the full alarm suite: high/low temperature, hot condenser, power failure, sensor error, low battery, high ambient temperature, door ajar, and start-up delay, with USB, remote alarm contact, 5V port, and optional RS-485. Sixteen racks on 3 adjustable shelves hold up to 400 two-inch boxes, and both CO₂ and LN₂ backup are available as options.
Frequently Asked Questions
How does the 578JA compare to the 579BPT and 578BPST? All three are the same ~578 L class. The 578JA is a single fixed-speed system (best value). The 579BPT adds variable-speed frequency-conversion for lower energy and quieter operation. The 578BPST adds a second fully independent circuit for redundancy.
What temperature does it reach? −86°C cooling performance across a −40°C to −86°C range.
How many boxes does it hold? 578 L across 16 racks, up to 400 two-inch boxes on 3 adjustable shelves behind 4 inner doors.
What power does it use? 208–230 V / 60 Hz (220V nominal), up to 1600 W, UL certified.
Can it take a backup system? Yes, optional CO₂ and LN₂ backup.
Ordering & Configuration
The DW-86L578JA is a capital freezer: request a quote for pricing, freight, and siting. It ships palletized and benefits from a documented placement and validation plan. Backed by Haier Biomedical's manufacturer warranty. Confirm current terms and lead time with your quote.
Choose the DW-86L578JA when you want full 578 L −86°C upright capacity at the best price and a single refrigeration system meets your risk tolerance. Step up to the DW-86L579BPT for lower energy and noise, or the DW-86L578BPST for dual-circuit sample-security redundancy.
