High-Performance Dual-Zone Refrigerator Freezer for Medical & Lab Use

The METHER 368L refrigerator freezer combo is purpose-built for laboratory and medical environments requiring precise, dual-temperature control. With separate cooling zones—refrigeration at 2–8°C and deep freezing at –10°C to –25°C (optional –20°C to –40°C)—it ensures optimal storage for vaccines, reagents, medications, and biological samples.

Independent Cooling Systems for Reliable Temperature Stability
Equipped with two dedicated compressors and digital temperature controllers, the unit prevents thermal interference between compartments. This independent system architecture guarantees stable performance, even under continuous use in clinical or research settings.

Optimized Cooling Technology
The upper refrigerator chamber features fan-assisted air circulation to maintain even cooling and fast temperature recovery after door openings. The lower freezer compartment uses static cooling with durable copper tube evaporators for low-temperature stability. A heated glass door eliminates condensation, ensuring clear visibility and easy access.

Safety Features and Intelligent Monitoring
Designed with built-in alarms for high/low temperature, door ajar, and power failure, the METHER 368L supports laboratory safety and compliance protocols. Optional features like USB data logging and lockable doors provide enhanced data security and access control.

Compact Yet Spacious Cold Storage Solution
Combining 368 liters of total capacity with a vertical footprint, this dual-chamber unit saves space while meeting diverse cold storage requirements. It uses eco-friendly, CFC-free refrigerants for efficient and sustainable operation in medical, pharmaceutical, and scientific facilities.

✅ 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
