Ultra-Low Temperature Storage for Research (-86°C)
Research laboratories storing biological specimens, cell cultures, enzymes, DNA/RNA samples, and tissue collections require ultra-low temperature storage to maintain sample integrity over months and years. WinHyCare offers three distinct ULT refrigeration technologies, each optimized for different laboratory priorities. All models reach -86°C with 1°C increment precision, include comprehensive alarm systems, USB data logging, and VIP insulation panels for superior thermal performance. Choose the technology that best matches your facility's requirements for redundancy, energy efficiency, and maintenance simplicity.
- -40°C to -86°C range
- 188L to 838L capacities
- 3 refrigeration technologies
- VIP insulation panels
Dual System Technology — Maximum Sample Protection
For laboratories storing irreplaceable specimens — patient biobank samples, long-term clinical trial materials, or unique research collections — the dual compressor system provides the highest level of protection. If one refrigeration system fails, the second automatically maintains -70°C, preventing catastrophic sample loss. WinHyCare dual system models (WDF-86V408D, WDF-86V588D, WDF-86V838D) feature four insulated inner compartments that minimize frost buildup and temperature fluctuation when accessing specific sections. The 7-inch LCD touch screen provides intuitive monitoring, while the USB data port supports compliance documentation for GLP and GMP-regulated environments.
- Dual compressor redundancy
- Backup maintains -70°C if one system fails
- 408L, 588L, and 838L models
- 4 insulated inner compartments
Cascade System — Energy-Efficient Performance
The cascade refrigeration system uses two refrigeration cycles operating in series — the first pre-cools the second — to efficiently reach -86°C. WinHyCare cascade models (WDF-86V340II through WDF-86V838) use HC (hydrocarbon) refrigerant that delivers approximately 50% energy savings compared to conventional ULT freezers. This makes cascade technology the preferred choice for facilities managing multiple freezers where energy consumption significantly impacts operating budgets. Available in six capacities from 340L to 838L, cascade models share the same alarm systems, touch screen controls, and VIP insulation as the dual system series.
- HC refrigerant — 50% energy saving
- 340L to 838L range
- Same alarm systems as dual models
- Lower operating costs for multi-freezer labs
Self-Cascade System — Simplified Reliability
Self-cascade technology achieves -86°C using a single compressor with a mixed refrigerant blend. Fewer mechanical components mean reduced maintenance requirements, lower noise levels, and a more compact footprint — making self-cascade models ideal for smaller labs, university departments, and clinical facilities where simplicity and reliability are prioritized. WinHyCare self-cascade models (WDF-86V188E through WDF-86V838E) range from the compact 188L unit for bench-adjacent placement to the 838L for high-capacity departmental storage. All include digital touch screen controls, comprehensive alarms, and USB data export.
- Single compressor — fewer parts
- Lower noise and maintenance
- 188L to 838L range
- Compact footprint options
Biomedical Deep Cold Storage (-40°C)
Not all laboratory samples require ultra-low temperatures. Reagents, certain biological materials, and routine specimens can be stored effectively at -25°C to -40°C. WinHyCare's -40°C medical freezer (WDF-40V528) provides 528L of microprocessor-controlled, forced-air cooled storage with the same level of alarm protection and temperature documentation as our ULT range. Auto-defrost, password-protected controls, adjustable shelves with interior lighting, and caster wheels for repositioning make this freezer practical for daily laboratory workflows.
- -10°C to -40°C range
- 528L capacity
- Auto-defrost system
- Password-protected controls

Common questions about laboratory cold storage solutions.
Dual system uses two independent compressors — if one fails, the other maintains -70°C (maximum protection). Cascade uses two compressors in series with HC refrigerant for 50% energy savings (best efficiency). Self-cascade uses a single compressor with mixed refrigerants for simpler maintenance and lower noise (best simplicity). All three reach -86°C.
The WDF-86V188E self-cascade model offers 188L of -86°C storage in the most compact footprint. It uses single compressor technology for lower noise and maintenance, making it ideal for smaller laboratories, university departments, and clinical settings with limited floor space.
All ULT models include USB data ports for downloading temperature logs, digital displays with 0.1°C resolution for monitoring, comprehensive alarm systems with remote contacts for LIMS integration, and can be connected to facility-wide monitoring systems. Temperature records support audit trail requirements in regulated environments.
Our cascade models use HC (hydrocarbon) refrigerant that achieves approximately 50% energy savings compared to conventional ultra-low freezers. Combined with VIP insulation panels and optimized door seals, cascade technology provides the most cost-efficient ULT storage for labs operating multiple freezers.
Many reagents, certain biological materials, and routine specimens can be stored at -25°C to -40°C. Our WDF-40V528 medical freezer provides 528L of -40°C storage at significantly lower cost and energy consumption than ULT freezers. Consult your sample storage protocols to determine the required temperature.
Most models operate on 220V/50Hz with a wide voltage tolerance of 185V to 260V, accommodating the power fluctuations common in many laboratory and hospital environments. Self-cascade models offer particularly wide voltage compatibility for varied installation conditions.
