The Liebherr SUFsg 7001 MediLine is a larger-capacity ultra-low temperature upright freezer, built for the reliable long-term preservation of critical samples and specimens in medical, pharmaceutical, and research environments. It reaches an exceptionally deep temperature range of -40 °C to -86 °C using a static cooling system with environmentally conscious R290/R170 refrigerants. With a gross capacity of 728 liters (700 liters usable) and generous interior dimensions of 890/605/1300 mm, the unit offers ample storage across three adjustable shelves plus four dedicated freezer compartment shelves, each rated for 50 kg of loading. The steel housing is finished in white, while the door is solid steel and the interior liner is stainless steel — a durable, corrosion-resistant construction designed for years of continuous ultra-low temperature operation.
Achieving and holding such extreme temperatures across this larger footprint demands substantial insulation and power: the SUFsg 7001 features 103–180 mm of insulation to minimize thermal loss, along with a manual defrost system and a connection rating of 7.0 A (50 Hz / 230 V). This translates to an annual energy consumption of 2,957 kWh, reflecting the intensive demands of ultra-low temperature freezing at scale, and the unit is rated to operate safely in ambient temperatures between +16 °C and +32 °C.
Monitoring and security features are built in to protect valuable, irreplaceable samples. An electronic controller with external digital temperature display allows for clear, at-a-glance monitoring, while visual and audible warning signals alert staff immediately to any fault. A volt-free alarm contact and LAN (Ethernet) interface enable integration with building management or remote monitoring systems, ensuring rapid response wherever the unit is located. The freezer includes a fitted lock for secure access, a defrost water drain for convenient maintenance, and right-hand door hinges. At 361 kg gross weight, the SUFsg 7001 is backed by Liebherr's 5-year warranty — a strong assurance of long-term reliability for a high-capacity appliance built to safeguard critical, high-value stored materials.
