Haier DW-86L728J Ultralow -86°C Freezer, ENERGY STAR 728L (25.7 cf)

Description

Haier DW-86L728J Ultralow -86°C Freezer – Product Highlights

• 728L (25.7 cu. ft.) large-capacity ultralow storage in an upright -86°C cabinet rated for biorepository, pharmaceutical, hospital, and high-volume research applications requiring sustained deep freeze preservation of large biological specimen inventories across multiple sample types and collection programs.
• Four independent removable foam inner doors allow individual compartment access without opening the full interior, minimizing frost buildup and temperature recovery time during repeated sample retrieval — a critical sample protection advantage in high-throughput ULT upright freezer workflows.
• Hydrocarbon (HC) refrigeration system saving power by 50% over conventional ULT freezer designs, combined with ENERGY STAR certification, high-performance VIP insulation panels, and a patented cabinet insulation system engineered to minimize heat gain and maintain stable temperature uniformity across the 728L interior.
• Wide-range voltage system (185V–260V) with built-in voltage compensation and protection against extreme high voltages allows installation in facilities with inconsistent power infrastructure, with simultaneous display of input voltage and ambient temperature for continuous environmental monitoring at the control panel.
• Comprehensive alarm suite with audible buzzer and visible flashing light outputs covering high/low temperature, door ajar, power failure, hot condenser, high ambient temperature, sensor error, and low battery — plus user-settable protection code, configurable delay-to-start, and remote alarm dry contact output for facility monitoring system integration.
• Suitable for 10°C to 32°C ambient operating environments, with a field-proven reliability record across blood stations, hospitals, disease control and prevention centers, and life science research institutions operating in variable environmental conditions worldwide.
• Stainless steel interior option available (DW-86L728J series), supporting pharmaceutical GMP cold storage and cleanroom-adjacent environments where interior surface compatibility, corrosion resistance, and decontamination requirements are part of facility procurement or validation criteria.
• USB interface, dry contact remote alarm, and 5V power supply port standard, with optional RS232/485 port, CO2 backup system, LN2 backup system, and temperature chart recorder available for facilities requiring data connectivity, networked cold chain oversight, or continuous sample protection during power interruptions aligned with pharmaceutical and biopharma storage compliance programs.
• Pressure equalization port with heated, spring-assisted mechanism prevents icing on the vent and allows immediate door re-access after initial opening — eliminating the typical waiting period associated with sealed -86°C upright freezers in high-frequency sample access environments.

Frequently Asked Questions – Haier DW-86L728J Ultralow -86°C Freezer

What is the Haier DW-86L728J and what applications is it designed for?

The Haier DW-86L728J is a 728L (25.7 cu. ft.) upright ultra-low temperature freezer rated to -86°C, designed for long-term preservation of biological specimens including plasma, serum, cell lines, enzymes, genomic and proteomic samples, and pharmaceutical compounds in high-volume biorepository operations, research universities, hospital systems, blood banks, disease control and prevention centers, and pharmaceutical and biopharmaceutical manufacturing facilities that require large-capacity, sustained deep freeze cold storage.

How do the four independent inner doors on the DW-86L728J protect stored samples?

The DW-86L728J features four individual removable foam inner doors that can each be opened independently, allowing access to a single storage compartment without exposing the full interior to ambient air; this minimizes frost buildup inside the chamber, reduces temperature recovery time after each door opening, and provides the maximum protection of stored samples during high-frequency retrieval workflows — a design advantage for biorepositories and clinical laboratories where specimens are accessed repeatedly throughout the day.

Is the Haier DW-86L728J ENERGY STAR certified, and what certifications does it carry?

The DW-86L728J carries ENERGY STAR and CE certifications; UL listing is available on the DW-86L728JA variant — laboratories or institutions with UL listing requirements should confirm which model variant is appropriate for their facility; the ENERGY STAR certification reflects the unit’s hydrocarbon (HC) refrigeration system, which delivers 50% energy savings over conventional ULT freezer designs and supports institutional sustainability initiatives and energy reporting programs.

What are the electrical requirements and operating conditions for the DW-86L728J?

The DW-86L728J operates on 220–240V/50Hz, 120V/60Hz (18A), or 208–230V/60Hz (10A) power supply, with a wide-range voltage system accommodating 185V–260V to allow installation in facilities with variable or poor power quality; the unit is rated for 10°C–32°C ambient operating temperature, and the control panel simultaneously displays input voltage and ambient temperature for continuous environmental monitoring; exterior dimensions are 1049 × 980 × 1980 mm (41.3 × 38.6 × 78.0 in) with a net weight of 345 kg (760.6 lbs).

How does the DW-86L728J compare to the smaller Haier -86°C upright freezer models?

The DW-86L728J provides 728L (25.7 cu. ft.) of storage capacity, making it the largest upright model in the Haier J-series with ENERGY STAR certification, compared to 578L (20.4 cu. ft.) and 338L (11.9 cu. ft.) options available in the same series; all models share the HC refrigeration system, VIP insulation, and core alarm and connectivity features, while the 728J adds the four-compartment independent inner door system and wide-range voltage tolerance suited to larger facilities and international deployment; explore the full ULT freezer range to compare capacity options.

What remote monitoring and data connectivity options are available for the DW-86L728J?

The DW-86L728J includes a USB interface for temperature data downloading, dry contact remote alarm output for facility monitoring system integration, and a 5V power supply port as standard features; an optional RS232/485 port is available for serial data connectivity to LIMS or building management platforms, and an optional temperature chart recorder supports standalone continuous documentation; optional CO2 and LN2 backup systems are also available for facilities requiring uninterrupted cold storage protection during power interruptions.
