The dual cooling system delivers fast pull-down (4.5 hrs) and rapid door recovery (80 min) with ±2.5 °C uniformity. Advanced vacuum insulation panels and dual-layer inner doors provide maximum cold retention, optimal uniformity, and reduce energy use by 40%. The freezer holds up to 400 2-inch boxes (40,000 samples) and includes a 7-inch color touch screen, USB data logging, and a low-voltage alarm, ensuring safe, reliable storage while extending compressor lifespan.
