528L Medical Refrigerator Freezer | Dual-Zone Cold Storage for Vaccines & Medications

Overview:

The METHER 528L is a combined refrigerator and freezer unit designed for reliable medical cold storage. With two independently controlled chambers, it provides stable temperature environments for sensitive products like vaccines, medicines, reagents, and biological samples.

Key Features:

• Two Separate Chambers:
  Upper refrigerator (273L) operates at 2–8°C; lower freezer (255L) maintains –10°C to –25°C or –20°C to –40°C. Each zone has its own compressor and digital controller.

• Efficient Cooling Performance:
  Refrigerator uses fan-forced cooling for even air distribution. Freezer applies static cooling with copper tube evaporators for consistent deep freezing.

• Durable and Hygienic Build:
  Features heated glass door to prevent condensation, and antibacterial-coated cold-rolled steel for easy cleaning and long-term use.

• Alarm System & Optional Logger:
  Includes audio-visual alarms for over-temperature, door ajar, and power failure. Optional USB data logger and lockable doors for added safety and compliance.

• Compact, High-Capacity Design:
  Offers a total of 528L storage with a compact footprint, ideal for hospitals, clinics, pharmacies, and research labs.

Applications:

Best suited for vaccine storage, pharmaceutical inventory, clinical testing materials, and temperature-sensitive lab supplies.

✅ Key Features & Benefits

• Dual Cooling System
  Two fully independent cooling circuits with separate controls provide reliable performance and individual temperature settings for upper and lower chambers.

• Temperature Uniformity & Stability
  Forced air cooling in the refrigerator and static cooling in the freezer ensure ±3°C uniformity, rapid recovery after door openings, and minimized fluctuation to protect sensitive samples.

• Optimized Performance
  Thick high-density PU foam insulation enhances thermal retention, while the fan-assisted circulation ensures consistent temperature across the interior. The system is CFC-free and energy-efficient.

• Alarm & Safety Systems
  Equipped with multi-level alarms (temperature, door ajar, power failure) and optional locking mechanisms, this unit is compliant with strict safety and clinical storage standards.
