Meling Biomedical DW-YL270 -10 to -25°C Upright Biomedical Freezer 270 L

The Meling Biomedical DW-YL270 is a 270 L upright biomedical freezer designed for controlled storage of temperature-sensitive materials between -10°C and -25°C. It combines microprocessor temperature control, seven individual ABS storage drawers, integrated local temperature recording, multiple alarm functions, and a secure solid-door cabinet in a space-efficient upright design. The freezer is suitable for laboratories, research facilities, clinical environments, and other professional facilities requiring organized frozen storage.

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 adjustments displayed in 0.1°C increments. Direct cooling supports stable low-temperature operation, while the manual-defrost design reduces the temperature cycling associated with automatic defrost systems. The freezer is designed to operate in ambient temperatures from 16°C to 32°C and uses R600a hydrocarbon refrigerant.

Key Features

• 270 L storage capacity in a compact upright cabinet

• Seven removable ABS drawers for organized storage and separation of materials

• Microprocessor temperature controller with a digital display

• Temperature display in 0.1°C increments

• Operating temperature range from -10°C to -25°C

• Direct-cooling refrigeration system

• Manual defrost for controlled low-temperature storage

• R600a hydrocarbon refrigerant

• Solid foam-insulated door to reduce heat transfer

• Key-operated safety lock for controlled access

• Spray-coated aluminum interior

• Pre-coated metal exterior

• 25 mm access port for independent probes or monitoring equipment

• Circuit breaker for electrical protection

• Backup battery supporting continued local monitoring and alarm functions during a power interruption

• Two rear casters and two front levelling feet for positioning and stabilization

Temperature Performance

Manufacturer internal testing reports:

• Temperature fluctuation of approximately 1.1°C

• Pull-down time to -25°C of approximately 1.9 hours

• Temperature recovery time of approximately 0.5 hours after the door has been opened for one minute

These figures are based on manufacturer internal testing with the freezer set to -23°C and operated at an ambient temperature of 22°C. Actual performance may vary depending on cabinet loading, ambient conditions, installation, ventilation, 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 integrated USB port for documentation, audits, quality-control procedures, and local recordkeeping.

The RS485 interface and remote alarm contact can support compatible on-site monitoring equipment, alarm panels, 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 records remain stored locally within the freezer and can be accessed or exported directly through the USB data logger. Local RS485 communication and remote alarm-contact functionality remain available for compatible on-site systems.

Designed for Professional Facilities

The DW-YL270 combines organized drawer storage with a relatively narrow cabinet footprint. Its seven separate drawers allow facilities to divide materials by department, project, storage period, or inventory category while limiting exposure of the remaining contents during routine access.

The solid insulated door, safety lock, local data logger, backup battery, alarm system, and external monitoring interfaces make the freezer suitable for professional environments requiring controlled access and documented frozen storage.
