Meling Biomedical DW-YL450 −10°C to −25°C Dual-Compartment Upright Biomedical Freezer 450 L

The Meling Biomedical DW-YL450 is a 450 L upright biomedical freezer designed for controlled storage of temperature-sensitive materials between −10°C and −25°C. Its dual-compartment cabinet provides two separately accessible storage sections with a total of twelve ABS drawers, helping facilities organize materials while reducing unnecessary exposure of the entire cabinet during routine access. The freezer combines microprocessor temperature control, dual-compressor direct cooling, local temperature recording, comprehensive alarms, and secure solid-door construction for professional laboratory, clinical, research, and institutional environments.

Certifications

• UL certified for applicable United States safety requirements

• cUL certified for applicable Canadian safety requirements

• CE marked for conformity with applicable European requirements

The microprocessor controller provides clear digital temperature monitoring with temperature adjustments displayed in 0.1°C increments. A direct-cooling refrigeration system and manual-defrost design support controlled low-temperature storage without the periodic cabinet warming associated with automatic defrost cycles. Two compressors provide refrigeration for the dual-compartment cabinet, while R600a hydrocarbon refrigerant supports efficient operation.

Temperature Performance

Manufacturer internal testing reports:

• Temperature fluctuation of approximately 2.0°C

• Pull-down time to −25°C of approximately 2 hours

• Temperature recovery time of approximately 0.6 hours after a door has been opened for one minute

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

• Power failure

• Low backup-battery level

• Temperature-sensor error

• Door-ajar condition

• Data-logger failure

• Local data-communication failure

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

Local Temperature Data Management

The built-in data logger records cabinet temperature locally at ten-minute intervals and can store up to 100,000 temperature records. Authorized users can export stored records directly through the USB port for documentation, audits, quality-control procedures, and local recordkeeping.

The remote alarm contact can connect the freezer to a compatible on-site alarm panel, monitoring system, or building-management system 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 records remain stored locally within the freezer and can be accessed or exported directly through the built-in USB data logger. The remote alarm contact remains available for compatible on-site monitoring systems.

Designed for Organized High-Volume Storage

The DW-YL450’s two-door, dual-compartment layout allows personnel to access one storage section without opening the other. Twelve individual ABS drawers support separation by department, project, material type, storage period, or inventory category.

The combination of drawer-based organization, solid insulated doors, safety locks, local data logging, backup monitoring, and comprehensive alarms makes the freezer suitable for professional facilities that require secure and documented frozen storage.
