Hoshizaki CR3S-FGE Triple Glass Door Laboratory Refrigerator
The Hoshizaki CR3S-FGE Triple Glass Door Laboratory Refrigerator combines the rugged reliability of Hoshizaki's commercial refrigeration platform with the performance required for laboratory cold storage. Designed for continuous operation, the CR3S-FGE offers an impressive 74.3 cubic feet of nominal storage capacity (68.1 cubic feet usable), making it an excellent choice for biotechnology companies, pharmaceutical manufacturers, hospitals, universities, research laboratories, and biorepositories that require centralized refrigerated storage for large inventories of temperature-sensitive materials.
Hoshizaki has earned an outstanding reputation for building refrigeration systems that deliver exceptional durability, rapid temperature recovery, and dependable long-term performance. The CR3S-FGE features a unique ducted air distribution system, dual compressor design, thermostatic expansion valves (TXVs), and energy-efficient multi-pane argon-filled Low-E glass doors that help maintain excellent temperature uniformity throughout the cabinet, even during periods of frequent access. These features make the refrigerator well suited for demanding laboratory environments where sample protection is critical.
Many laboratories pair the CR3S-FGE with ultra-low freezers for long-term biological preservation, laboratory freezers for frozen reagent storage, biosafety cabinets for sterile sample preparation, and centrifuges to create a complete laboratory cold storage workflow.
