Haier Ultra Low Temperature Freezers
[4 Models]Haier ultra-low-temperature freezers provide secure long-term storage for valuable biological samples and other temperature-sensitive materials at temperatures down to -86°C.
The range includes compact ULT storage for laboratories with limited space and high-capacity TwinCool models featuring two independent refrigeration systems for additional sample protectio
- Reliable -86°C ultra-low temperature storage
- Energy-efficient hydrocarbon refrigeration technology
- Designed for research, healthcare and life science laboratories
Secure Sample Storage
Maintain stable ultra-low-temperature conditions for valuable biological materials, research samples and other sensitive contents.
Intelligent Monitoring
Touchscreen control, data logging, alarm notifications and remote monitoring connectivity provide visibility of freezer performance.
TwinCool Protection
TwinCool models use two independent refrigeration systems, each capable of maintaining ultra-low temperatures if the other system requires attention.
Energy-Efficient Operation
Hydrocarbon refrigerants, frequency-conversion technology and advanced insulation help reduce energy consumption and operating costs.
Haier ULT freezers are designed for long-term sample preservation across life-science, clinical and research environments.
Typical applications include:
- Biological sample storage
- Blood, plasma and serum storage
- Viruses, bacteria and cell storage
- Tissue and organ-sample preservation
- Vaccine and pharmaceutical research
- Disease-control and prevention laboratories
- Biomedical engineering research
- University and scientific research laboratories
- Electronics, chemical and industrial sample storage
Compact models provide point-of-use storage beneath or beside laboratory benches. Larger upright models support centralised sample collections and higher-throughput biobanking facilities.s.
Ultra-Low-Temperature Performance
The range provides controlled sample storage at temperatures down to -86°C. Upright TwinCool models operate between -40°C and -86°C, while the compact model provides an extended range from -20°C to -86°C.
Dual Refrigeration Protection
TwinCool freezers feature two independent hydrocarbon refrigeration systems. Each system can maintain ultra-low-temperature conditions, helping protect samples if one refrigeration circuit develops a fault.
Frequency-Conversion Technology
Intelligent frequency-conversion compressors adjust cooling output according to demand. This supports temperature stability while reducing unnecessary energy use.
Natural Hydrocarbon Refrigerants
The refrigeration systems use hydrocarbon refrigerants with low global-warming potential, supporting more environmentally responsible ULT storage.
Touchscreen Control
TwinCool models feature a 10.1-inch touchscreen for temperature display, alarm management, historical data and system-status information.
ULT Freezer Alarm System
Multiple alarms warn users of high or low temperatures, power failure, sensor errors, low battery, an open door, high ambient temperature and other conditions that could affect stored samples.
Remote Monitoring Connectivity
USB, RS485 and remote alarm connections support data export and integration with compatible external monitoring systems. Optional connectivity can provide additional visibility of freezer performance.
Secure Access
Key locks, padlock facilities and optional electronic or fingerprint access help restrict access to valuable stored materials.
Rapid Door Re-entry
Pressure-relief technology reduces the time required to reopen the freezer following a door opening, supporting efficient sample retrieval.
Flexible Sample Organisation
Adjustable shelves, inner doors and compatible freezer racks help laboratories organise cryoboxes and samples around established workflows.
Compact ULT Freezer
The DW-86L100STL provides 100 litres of ultra-low-temperature storage in a compact format suitable for benchtop, stacked or undercounter installation.
Its space-saving design makes it suitable for laboratories that need samples close to the point of use without installing a full-size upright freezer.
TwinCool Frequency-Conversion ULT Freezers
The TwinCool range offers capacities from 578 to 828 litres. Two independent refrigeration systems provide additional protection for valuable sample collections, while frequency-conversion technology helps reduce energy consumption and noise.
Available models accommodate between 400 and 600 standard two-inch cryoboxes.
