SED-750BG-D — Precision Ultra-Low Temperature Freezer

Uses a new-generation eco-friendly ultra-low-temperature mixed refrigerant and precision copper-tube evaporator circuits, with an ultra-thick rigid polyurethane insulation layer. The microprocessor temperature-control system monitors internal temperature via sensors in real time and controls compressor start/stop to maintain the set ultra-low temperature. Two silicone rubber door seals prevent cold-air leakage. The refrigeration system includes an automatic self-cleaning function for long-term stable operation.
