Chest Style Ultra Low Freezers -40°C To -85°C, 22 cu.ft., Manual Defrost Overview
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.
Key Features
- 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.
