Midea Ultra-Low Temperature (Dual Guard Series)

The Midea Biomedical Dual Guard Series (MD-86L568BS, MD-86L708BS, and MD-86L818BS) delivers fail-safe, ultra-low temperature preservation at -86°C for biobanks, clinical diagnostics, and agricultural gene repositories. Driven by dual inverter compressor technology, this series achieves up to a 40% energy reduction compared to conventional models while maintaining strict spatial uniformity of ±5°C. Featuring dual independent refrigeration circuits, an intuitive 10.1-inch LCD touch screen, and whisper-quiet operation (≤51 dBA), the CE and UL certified Dual Guard Series guarantees maximum operational security and temperature stability for mission-critical samples.
 
Product Features
Dual-Circuit Failover Protection (Dual Guard™ Assurance)
Driven by two 100% independent refrigeration systems operating synergistically. If one cooling circuit ever encounters an issue, the backup system activates instantly to sustain critical ultra-low temperatures, eliminating the risk of catastrophic sample loss.
 
Precision Thermal Stability & Accelerated Pull-Down
Proprietary control algorithms synchronize dual variable-speed inverter compressors to maintain strict ±5°C spatial uniformity across the cabinet. Rapid cooling engineering accelerates temperature pull-down from room temperature (25°C) to -81°C in 192 to 210 minutes.
 
Smart-Inverter Energy Efficiency & Low-Noise Operation
Variable-frequency technology intelligently balances heat-load demand, reducing daily energy consumption by up to 40% compared to conventional fixed-speed systems (consuming 9.4 to 14.3 kWh/24h depending on model size). Advanced vibration dampening achieves ultra-low acoustic levels (49 to 51 dB(A)), ideal for open laboratory spaces.
 
Intuitive 10.1" LCD Touch Screen Interface
Features a high-definition 10.1-inch color touchscreen display with 0.1°C resolution, allowing effortless protocol programming, real-time performance graphing, event logging, and clear visual status tracking for sensitive biological storage.
