Haier Ultralow -86C Freezer, Energy Star 338L (11.9 cf)

Technical Specifications – Haier DW-86L338J Ultralow -86°C Freezer

Frequently Asked Questions – Haier DW-86L338J Ultralow -86°C Freezer

What is a ULT freezer and what is the Haier DW-86L338J used for?

A ULT (ultra-low temperature) freezer maintains storage temperatures at or below -80°C, enabling long-term preservation of biological specimens including plasma, serum, cell lines, enzymes, genomic samples, and pharmaceutical compounds that degrade at conventional freezer temperatures; the Haier DW-86L338J is a 338L upright ULT freezer rated to -86°C, designed for use in research laboratories, biorepositories, blood banks, pharmaceutical facilities, and vivarium operations requiring sustained deep freeze storage.

What is the difference between a -80°C freezer and a -86°C freezer?

The primary distinction is minimum attainable temperature — a -86°C ultralow freezer like the Haier DW-86L338J reaches a lower minimum setpoint than a standard -80°C unit, providing additional thermal margin for critical sample types or facilities operating in warm ambient environments where the freezer works against higher room temperatures; both designations refer to the same class of ultra-low temperature laboratory freezer, and the DW-86L338J is designed to deliver stable, verifiable temperature performance across the full -40°C to -86°C operating range.

Is the Haier DW-86L338J ENERGY STAR certified?

Yes — the Haier DW-86L338J carries ENERGY STAR certification, reflecting its hydrocarbon (HC) refrigeration system that operates at 45% greater efficiency than conventional ULT freezer designs; for laboratories and institutions managing sustainability initiatives, energy reporting requirements, or facility compliance programs, the DW-86L338J’s certified efficiency profile supports both operational cost reduction and environmental impact goals across long-term laboratory cold storage deployments.

Does the Haier DW-86L338J require any special electrical or infrastructure installation?

Specific electrical requirements including voltage, amperage, and circuit specifications were not listed on the product page and should be confirmed directly with ARES Scientific prior to installation planning; the DW-86L338J is an upright cabinet model with a slim footprint intended for standard laboratory floor placement, and optional CO2 or LN2 backup systems will require additional infrastructure planning for gas supply lines if selected.

Is the Haier DW-86L338J compatible with existing freezer racking systems?

Yes — the DW-86L338J is designed with compatibility for existing racking systems from competitor manufacturers, allowing laboratories to transition to Haier ultralow storage without replacing internal storage infrastructure; optional Haier storage racks and storage boxes are also available for new installations, and the unit’s 338L (11.9 cu. ft.) upright interior accommodates standard biorepository racking configurations used across research and clinical ULT freezer programs.

What alarm and monitoring features does the Haier DW-86L338J include?

The DW-86L338J includes a malfunction alarm, automatic clean-filter alarm, and sensor error alert, all displayed through the microprocessor-controlled LED digital interface; an optional RS232/485 port supports connection to external laboratory data management and remote temperature monitoring systems for facilities requiring networked oversight, audit trail documentation, or integration with institutional cold storage compliance programs.
