Ultra-Low Temperature Freezer MDF-DU500ZHL-PC 525 L (CAT#: STEM-BC-2678-ZJF)

The MDF-DU500ZHL-PC is an ultra-low temperature freezer designed for research sample preservation. It provides 525 L of storage capacity and operates from -40°C to -86°C. FrostLess technology uses an upgraded inner door, improved gasket, door frame, and handle structure to reduce frost formation. The enhanced insulation design helps lower defrosting frequency. Natural hydrocarbon refrigerant combined with inverter technology supports efficient cooling. The refrigeration system helps restore temperature after door opening. A new inverter compressor operates under PID control to maintain stable internal temperature. Low-speed compressor operation supports reduced energy consumption during stable operating conditions.
