Ultra-Low Temperature Freezer MDF-DU503VXHL-PC 528 L (CAT#: STEM-BC-2686-ZJF)

The MDF-DU503VXHL-PC is an ultra-low temperature freezer designed for secure research sample storage. It provides 528 L of capacity and operates from -40°C to -86°C. The TwinGuard ECO dual refrigeration system uses two independent refrigeration circuits for ultra-low temperature operation. If one refrigeration circuit is affected, the remaining circuit can maintain -75°C to reduce sample damage risk. Natural hydrocarbon refrigerant combined with inverter technology supports efficient cooling. The system helps maintain cooling performance and temperature recovery after door opening. A new inverter compressor operates under PID control to maintain stable cabinet temperature. Low-speed compressor operation supports lower energy use during stable storage.
