🔬2、 Technical characteristics and innovative design

Efficient temperature change system

Nonlinear temperature controlUsing dynamic PID algorithm to automatically compensate for environmental interference and avoid temperature overshoot (overshoot<2 ℃).
Cascade refrigeration technologyThree stage compression (high-temperature R404A+low-temperature R23) combined with liquid nitrogen injection assistance, achieves rapid response to -70 ℃ deep cooling (cooling to -70 ℃ only takes 40 minutes).
Magnetic levitation compressorEquipped with magnetic levitation technology at low temperatures, energy efficiency is improved by 60%, reducing compressor start-up and shutdown losses.

Structural optimization and reliability

Box materialThe inner liner is made of SUS304 stainless steel (corrosion-resistant), the outer box is coated with anti-static carbon steel plate, and the insulation layer is made of 80mm polyurethane foam material (energy-saving by 30%).
duct designThree dimensional turbulent circulation system (wind speed 5m/s)+nano turbulence element, ensuring temperature uniformity error of ≤± 1.5 ℃.
safety protectionMultiple redundancy protection (over temperature/over-current/compressor overpressure/leakage protection), supporting power-off continuation function (automatic recovery interruption test).

Intelligent operation and maintenance

AI fault predictionWarning potential faults based on historical data (such as abnormal compressor bearings, 14 days in advance).
remote monitoringBuilt in 5G module, supporting real-time program control and fault diagnosis on mobile devices (such as E03 code=fan abnormality).

🚀3、 Application scenarios
