Chest Style Ultra Low Freezers -40°C To -85°C, 3 cu.ft., Manual Defrost Overview
A cascade refrigeration system pairs two hermetic compressors with CFC- and HCFC-free R-508B and R-404A refrigerants to reach -85°C. Air-cooled twin heavy-duty fans handle condensing, so no liquid coolant is required. The chamber uses 14-gauge zinc-coated galvanized steel; an exterior of 16-gauge steel carries a power-coated cool gray finish.
Key Features
- Cascade refrigeration: two hermetic compressors with CFC- and HCFC-free R-508B and R-404A refrigerants reach -85°C.
- Digital dual-display control: shows set point and chamber temperature, with a scan button for setting and a tamper-proof lockout.
- Battery-operated alarm system: audible and visual signals on mechanical or electrical failure, over/under-temperature settings, silencing switch, battery test switch, and a relay for remote hook-up.
- Automatic power-failure recovery: a timer system restarts the unit after power is restored.
- Air-cooled condenser: two heavy-duty fans dissipate heat with no liquid coolant required.
