Chest Style Ultra Low Freezers -40°C To -85°C, 5 cu.ft., Manual Defrost Overview
Cascade refrigeration pairs two hermetic compressors with CFC-free R-508B and R-404A refrigerants, reaching ultra-low temperatures without liquid coolant. Air-cooled condensing uses two heavy-duty fans. The chamber is built from 14-gauge zinc-coated galvanized steel; the exterior uses 16-gauge steel finished in powder-coated cool gray. Interior space measures 30″ × 18″ × 16″ and accepts up to 15 racks.
Key Features
- Cascade refrigeration: two hermetic compressors and CFC-free R-508B and R-404A refrigerants reach −85°C without liquid coolant.
- 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 unit once power is restored.
