Chest Style Ultra Low Freezers -40°C To -85°C, 22 cu.ft., Manual Defrost Overview
The Chest Style Ultra Low Freezers -40°C To -85°C, 22 cu.ft., Manual Defrost (model ULF801C) from Yamato Scientific is a laboratory ultra-low freezer delivering a -40°C to -85°C range across 22 cu.ft. (626 L) of chest-style storage. LabSupplies.com supplies this unit as an authorized dealer. Standard equipment includes a microprocessor digital controller, audible and visual alarms, remote alarm contacts, alarm battery back-up, and a 1/2" access port.
Construction pairs a 14-gauge zinc-coated galvanized steel chamber with a 16-gauge steel exterior finished in power-coated cool gray. A cascade refrigeration system runs two hermetic compressors charged with CFC-free R-508B and HCFC-free R-404A. Air-cooled condensing uses two heavy-duty fans, so no liquid coolant is required. Interior space holds up to 36 racks across a 67" × 19" × 30" chamber.
Electrical configurations cover 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 98" × 36" × 43.5", and the freezer ships at 1,075 lbs. Built in the USA, the unit is UL Listed. Power-failure recovery uses an automatic timer that restarts the compressors once power returns.
Key Features
- Digital temperature control: microprocessor controller with dual display showing set point and chamber temperature, a scan button for setting, and tamper-proof lockout.
- Cascade refrigeration: two hermetic compressors with CFC-free R-508B and HCFC-free R-404A refrigerants reach the -40°C to -85°C range.
- Battery-backed alarm system: audible and visual signals on mechanical or electrical failure, over- and under-temperature settings, silencing switch, battery test switch, and a relay for remote alarm hook-up.
- Power-failure recovery: an automatic timer system restarts the unit after a power failure.
- Air-cooled condensing: two heavy-duty fans cool the condenser with no liquid coolant required.
- 22 cu.ft. chest capacity: 626 L interior holds up to 36 racks for high-density sample storage.
How to Choose the Right Ultra-Low Freezer
Matching an ultra-low freezer to your lab means weighing storage density, achievable temperature, and the power available at the install site. Use these axes to scope the right unit.
- Capacity: a 22 cu.ft. (626 L) chamber holding up to 36 racks suits labs storing large sample inventories; confirm rack format before ordering.
- Temperature range: a -40°C to -85°C span covers most biological and reagent cold-chain needs; verify your lowest required set point.
- Control type: a microprocessor digital controller with dual display and tamper-proof lockout protects set points in shared facilities.
- Voltage: confirm site power against the 115V, 208V, 230V (60 Hz) and 220V (50/60 Hz) single-phase options before installation.
- Footprint: chest-style units occupy floor space differently than uprights; plan for the 98" × 36" × 43.5" exterior and access clearance.
- Safety and monitoring: battery-backed audible/visual alarms and a remote alarm relay matter for unattended overnight protection.
