Chest Style Ultra Low Freezers -40°C To -80°C, 21Cu.Ft., Manual Defrost Overview
Chest construction pairs a 14-gauge zinc-coated galvanized steel chamber with a 16-gauge steel exterior finished in powder-coated cool gray. A cascade refrigeration system runs two hermetic compressors with CFC-free R-508B and R-404A refrigerants. Air-cooled condensing uses two heavy-duty fans, so no liquid coolant is required to reach -80°C.
Key Features
- Cascade refrigeration: two hermetic compressors with CFC- and HCFC-free R-508B and R-404A refrigerants reach the -80°C floor.
- Digital temperature control: dual display shows set point and chamber temperature, with a scan button for setting and a tamper-proof lockout.
- Battery-backed alarm system: audible and visual signals fire on mechanical or electrical failure, with over- and under-temperature settings, a silencing switch, and a battery test switch.
- Automatic power-failure recovery: a timer system restarts the freezer after a power interruption.
- Air-cooled condenser: two heavy-duty fans cool the system with no liquid coolant required.
