Platinum Upright Style Ultra Low Freezers -40°C To -80°C, 30 cu.ft., Manual Defrost Overview
The Platinum Upright Style Ultra Low Freezers -40°C To -80°C, 30 cu.ft., Manual Defrost (model ULF901UP) is an upright laboratory ultra-low freezer from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. Each unit delivers 30 cu.ft. of sample storage and holds a -40°C to -80°C operating range with manual defrost.
Chamber walls use 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel powder-coated cool gray. A cascade refrigeration system pairs two hermetic compressors with CFC-free R-508B and HCFC-free R-404A refrigerants. Air-cooled condensing relies on two heavy-duty fans, so no liquid coolant is required to reach ultra-low temperatures.
Power options cover 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 60.5" × 37" × 79.5", and the freezer ships at 1325 lbs. Made in the USA, the unit carries UL Listed certification.
Key Features
- Touch-screen controller: displays set point and chamber temperature, with a viewable temperature graph and multi-level security.
- Alarm system: battery-operated audible and visual alerts signal mechanical or electrical failure, backed by over- and under-temperature settings, a silencing switch, and a remote alarm relay.
- Connectivity and data logging: USB and Ethernet ports support data acquisition, FTP download, email and SMS notification, and VNC remote access from a PC or smart device.
- Cascade refrigeration: two hermetic compressors run CFC-free R-508B and HCFC-free R-404A to reach the -80°C range without liquid coolant.
- Storage configuration: 877 L interior with 4 adjustable shelves across 5 compartments and capacity for 35 racks.
- Power-failure recovery: an automatic timer restarts the unit once power returns, and a 1/2" access port ships with plugs.
