Meling Biomedical DW-HL110V −40°C to −86°C Undercounter Ultra-Low Temperature Freezer 110 L

The Meling Biomedical DW-HL110V is a 110 L undercounter ultra-low temperature freezer designed for long-term storage of temperature-sensitive biological materials between −40°C and −86°C. Its compact horizontal cabinet combines inverter-driven refrigeration, a 10.1-inch intelligent touchscreen, integrated local temperature recording, comprehensive alarm protection, and organized storage for up to approximately 9,000 cryogenic tubes. It is suitable for laboratories, research facilities, biobanks, clinical environments, and other professional facilities requiring dedicated ultra-low temperature storage near the point of use.

Certifications

• UL certified for applicable United States safety requirements

• cUL certified for applicable Canadian safety requirements

The microprocessor controller and 10.1-inch HD touchscreen provide clear access to temperature readings, system conditions, alarms, and operating information. The inverter-driven compressor adjusts refrigeration output according to cooling demand, while the direct-cooling system, manual-defrost design, hydrocarbon refrigerant, and substantial cabinet insulation support reliable operation down to −86°C.

Temperature Performance

Manufacturer prototype testing reports:

• Temperature fluctuation of approximately 1.5°C

• Daily energy consumption of approximately 4.48 kWh

• Cooling time to −80°C of approximately 100 minutes

These figures are based on manufacturer internal prototype testing with the freezer set to −80°C and operated at an ambient temperature of 25°C. Actual performance may vary between units and depending on cabinet loading, ambient conditions, ventilation, installation, initial product temperature, voltage conditions, and door-opening frequency.

Comprehensive Alarm Protection

The integrated alarm system provides visual and audible notification for conditions including:

• High cabinet temperature

• Low cabinet temperature

• High ambient temperature

• Hot condenser condition

• High refrigeration-system pressure

• Power failure

• Low backup-battery level

• Backup-power detection failure

• Temperature-sensor error

• Door-ajar condition

• Local data-communication failure

These alarms help personnel identify temperature excursions, power interruptions, refrigeration-system conditions, open-door events, and monitoring faults promptly.

Local Temperature Data Management

The built-in data logger records cabinet temperature locally at five-minute intervals and supports retention of up to ten years of historical records. Authorized users can export stored temperature data directly through the USB port for audits, documentation, quality-control procedures, and local recordkeeping.

The RS485 interface and remote alarm contact can connect the freezer to compatible on-site alarm panels, monitoring equipment, or building-management systems without requiring an internet connection.

Privacy-Focused Offline Operation

Internet connectivity, cloud communication, and external manufacturer-server data collection are disabled to support institutional privacy, cybersecurity, and data-governance requirements.

Temperature and alarm records remain stored locally within the freezer and can be accessed or exported directly through the built-in USB data logger. RS485 communication and remote alarm-contact functionality remain available for compatible on-site systems.

Designed for Space-Conscious Facilities

The DW-HL110V provides 110 L of −86°C storage in a cabinet measuring approximately 815 mm high. Its undercounter configuration allows facilities to position dedicated ultra-low temperature storage near laboratory workstations, processing areas, or frequently accessed sample collections.

The inverter-driven refrigeration system, touchscreen control interface, organized cryotube capacity, local data logger, backup battery, comprehensive alarms, access control, and heavy-duty casters support professional long-term biological-sample storage without requiring a full-height upright ULT freezer.
