The Haier DW-80WZ15 is a 15 L (0.53 cu ft) mini ultra-low freezer that reaches −80°C in a portable, benchtop-and-mobile form factor, running on standard 110V/60Hz AC or 24V DC for vehicle and field use. It gives field studies, sample transport, and small labs a genuine deep-cold −80 to −40°C range without a full ULT chassis.

Application Profile
Deep-cold storage is usually a fixed asset, but sample science increasingly happens away from the lab — collection sites, transport routes, field trials, and mobile clinics. The DW-80WZ15 brings a true −80°C capability to those settings: it is compact enough to carry, and its dual 110V AC / 24V DC power lets it run off a vehicle circuit in transit and off mains for long-term storage on arrival. That eliminates the dry-ice logistics and temperature uncertainty of passive coolers for the segment of samples that must stay near −80°C.
Direct-cooling hydrocarbon refrigeration drives the −80 to −40°C adjustable range, and at 15 L the unit holds a working set of aliquots or a batch of collected specimens. A safety lock secures the contents during transport, and the low 280 W draw suits vehicle and portable-power operation.
Design Architecture
The temperature controller with LED display lets you set the target across the −80 to −40°C band, and the freezer raises high/low temperature, power failure, and sensor error alarms so a transport excursion is caught immediately. The 24V DC input is the key workflow feature — plug into a vehicle's power system for continuous cooling in transit, then switch to 110V mains for holding at the destination, keeping the cold chain unbroken end to end.
Frequently Asked Questions
What temperature range does the DW-80WZ15 reach? It is adjustable from −40°C down to −80°C, with a −80°C cooling performance.
Can it run in a vehicle? Yes. It accepts 24V DC for mobile/vehicle operation as well as 110V/60Hz AC for long-term mains storage.
How much does it hold? 15 L — roughly up to 10 two-inch cryo boxes of working samples.
Is it a real −80°C freezer or a cooler? It is a compressor-driven mini ULT freezer that actively reaches −80°C, not a passive PCM/ice cooler.
How heavy is it? About 27 kg net (32 kg gross), compact at 690 × 320 × 500 mm.
Ordering & Configuration
The DW-80WZ15 is a capital purchase: request a quote for pricing and lead time. Backed by Haier Biomedical's manufacturer warranty — confirm current terms with your quote.
Choose the DW-80WZ15 when you need genuine −80°C storage that travels — field collection, sample transport, or a small point-of-use station — and dual AC/DC power. Step up to a full DW-86L upright when your samples stay in one place and box counts grow; use a PCM transport cooler instead only when you don't need active −80°C cooling.
