Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 14 cu.ft., Manual Defrost Overview
Construction pairs a 14-gauge zinc-coated galvanized steel chamber with a 16-gauge steel exterior finished in powder-coated cool gray. Two hermetic compressors drive the cascade refrigeration system, using CFC-free R-508B and R-404A refrigerants. An air-cooled condenser with two heavy-duty fans removes heat, so no liquid coolant is required. A 1/2" access port sits on the left-hand side with plugs.
Electrical options cover 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 72.5" × 33" × 47.5", and shipping weight is 900 lbs. Made in the USA, the unit carries UL Listed certification. Automatic power-failure recovery restarts the freezer after an outage.
Key Features
- Touch-screen controller: displays set point and chamber temperature, with multi-level security and a viewable temperature graph.
- Alarm system: battery-operated audible and visual signal on mechanical or electrical failure, with over- and under-temperature settings, silencing switch, battery test switch, and a relay for remote hook-up.
- Data and connectivity: USB port, ethernet port, FTP and USB data logging, plus email and SMS notifications and VNC remote access from a PC or smart device.
- Cascade refrigeration: two hermetic compressors with CFC-free R-508B and R-404A, cooled by an air-cooled condenser with two heavy-duty fans.
- Battery back-up: alarm battery back-up keeps monitoring active during power interruptions, and an automatic timer restarts the unit after a power failure.
How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer comes down to matching storage volume, temperature class, control depth, and site power to your sample protocols. Use the criteria below to confirm the unit fits both the workflow and the facility.
- Capacity: verify usable interior volume and rack count against your sample inventory; this model holds 14 cu.ft. (400 L) and accepts 30 racks.
- Voltage and site power: match the available circuit, since this unit offers 115V, 208V, 230V at 60 Hz and 220V at 50/60 Hz single-phase.
- Footprint and weight: measure your space and floor rating against the 72.5" × 33" × 47.5" exterior and 900 lb shipping weight.
