The Haier Biomedical –150°C Cryogenic Chest Freezer (DW-150W209) provides a safe, reliable, and energy-efficient ultra-low temperature storage solution for biological and industrial materials. Designed with Haier’s advanced dual-compressor cascade refrigeration technology, the freezer maintains a consistent –150°C environment — approximately 20°C below the water recrystallization temperature — to prevent ice crystal formation and ensure sample integrity during long-term storage.
Ideal for research institutions, hospitals, blood banks, biobanks, and epidemic control centers, the DW-150W209 offers a cost-effective and environmentally responsible alternative to liquid nitrogen storage systems.
