The Meling DW-FL270 vertical medical freezer is a low-temperature unit with a 270-liter storage capacity, designed to provide a stable environment between -20°C and -40°C. It is suitable for preserving plasma, vaccines, biological materials, and medical reagents that require precise and stable cooling in laboratories, hospitals, and research centers.

Main Features

Low-temperature cooling system with an operating range from -20°C to -40°C to maintain the stability of sensitive samples.
Seven internal ABS drawers to organize samples and reduce cross-impact between stored materials.
High-precision temperature control system with a digital display for easy reading and setting of cabinet temperature.
Double-layer insulated door with foam insulation to reduce cold loss and improve thermal efficiency.
High-efficiency compressor using a CFC-free refrigerant to help reduce energy consumption and noise.
Integrated, dust-resistant door gasket for a tight seal, reduced air leakage, and easy cleaning.
Bottom-mounted condenser to stabilize the cooling cycle performance and improve operating reliability.
External door handle with key lock to secure contents and prevent unauthorized access.

Physical security via an external door handle with key lock to restrict access to samples.

Applications

Storage of blood plasma at stable low temperatures.
Storage of vaccines that require low-temperature refrigeration.
Preservation of biological products and materials in research laboratories.
Storage of reagents and sensitive materials in university laboratories.
Use in hospitals and research centers that need low-temperature storage for various samples.

Guidelines When a High-Temperature Alarm Occurs

When a high-temperature alarm is triggered, check the following common causes and address them in order:

Make sure the freezer door is fully closed and that nothing is obstructing proper sealing.
Check for any recent power outage or electrical instability that may have affected temperature control.
Review the volume of newly loaded samples, especially if a large quantity of non-cooled items was added at once.
Inspect the condenser and clean any accumulated dust if necessary to improve heat exchange efficiency.
