Haier TwinCool Frequency Conversion ULT Freezer DW-86L828BPST

The Haier TwinCool Frequency Conversion ULT Freezer DW-86L828BPST is an ultra-low temperature laboratory freezer designed for long-term storage of biological samples such as viruses, blood cells, bacteria, and tissue, as well as electronics and other special materials. The unit provides a controlled temperature range from -40 to -86°C and is intended for use in hospitals, disease control centers, life science and medical research laboratories, bioengineering and pharmaceutical facilities. The freezer combines frequency-conversion compressors, hydrocarbon refrigerants and a dual independent refrigeration system to deliver sample security, rapid pull-down and temperature recovery.

Key Features:

• Capacity: 828 L (29.2 cu.ft)
• Temperature range: -40 to -86 °C
• Power supply: 100–230 V, 50/60 Hz
• Exterior dimensions (W×D×H): 1145 × 998 × 1980 mm
• Inner configuration: 3 shelves / 4 inner doors
• Dual independent hydrocarbon refrigeration systems; temperature uniformity within ±3 °C
• 10.1-inch touchscreen with optional IoT monitoring

Advantages:

• Dual independent refrigeration provides redundancy so each system can maintain -80 °C for enhanced sample safety.
• Frequency-conversion compressors with HC refrigerant deliver up to 50% energy reduction versus traditional HFC systems, lowering operating costs.
• Large 828 L capacity and modular shelving support high-density storage (up to 600 two-inch boxes, ~60,000 samples).
• Intelligent control with a 10.1-inch touch screen and optional IoT enables real-time monitoring, alarms and self-diagnostics.
