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

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

Overview:

The METHER 528L is a dual-zone cold storage unit that combines a 273L refrigerator (2–8°C) and a 255L freezer (–10°C to –25°C or –20°C to –40°C) in one vertical cabinet. Designed for medical, pharmaceutical, and laboratory use, it ensures precise, independent temperature control for sensitive items.

Core Features:

• Independent Cooling Systems:
  Each chamber operates with its own compressor and microprocessor controller for accurate, uninterrupted performance.

• Advanced Cooling Methods:
  Refrigerator section uses fan-assisted air circulation; freezer section uses static cooling with copper pipe evaporators for deep, stable freezing.

• Clean & Durable Build:
  Anti-fog heated glass door improves visibility. Cold-rolled steel body with antibacterial coating offers hygienic, long-term durability.

• Alarm System & Data Monitoring:
  Built-in alerts for temperature deviations, door ajar, and power failure. Optional USB data logger and lockable doors for enhanced security.

• Space-Efficient Design:
  Vertical layout saves floor space while offering 528 liters of total storage — ideal for compact medical environments.

Suitable For:

Hospitals, pharmacies, vaccination centers, clinical laboratories, biotechnology companies, and research institutions.

✅ 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.

✅ Application Areas

• Vaccines & Frozen Plasma

• Life Science Samples & Enzymes

• Reagents, Chemicals & Pharmaceuticals

• Microbial Cultures & Clinical Diagnostics
