Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 3 cu.ft., Manual Defrost Overview
Cascade refrigeration pairs two hermetic compressors with CFC-free R-508B and R-404A refrigerants, reaching ultra-low setpoints without liquid coolant. An air-cooled condenser uses two heavy-duty fans for heat rejection. The chamber is 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel powder coated cool gray. A 1/2-inch access port sits on the left-hand side with plugs.
Power options span 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz. Exterior dimensions measure 34.5 × 25.25 × 48 inches, with a shipping weight near 500 lbs. Built in the USA and UL Listed, the freezer arrives ready for installation. Automatic power-failure recovery restarts the unit after outages.
Key Features
- Touch-screen control: displays set point and chamber temperature, with Hi/Low alarms, a viewable temperature graph, and multi-level security.
- Connectivity and data logging: USB and Ethernet ports support data acquisition, downloads via USB or FTP, and VNC remote access from a PC or smart device.
- Alarm system: battery-operated audible and visual signals on mechanical or electrical failure, with over/under-temperature settings, silencing switch, and battery test switch.
- Remote notification options: email and SMS alerts, alarm-relay and power-failure dry contacts, and a relay for remote alarm hook-up.
- Cascade refrigeration: two hermetic compressors and CFC-free R-508B and R-404A refrigerants reach −85°C without liquid coolant.
How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer means matching storage volume, target temperature, and site infrastructure to your sample workflow. Weigh these axes before specifying a unit.
- Capacity: Match chamber volume and rack count to your sample inventory; this 3 cu.ft. chest holds up to 8 racks.
- Voltage: Verify available site power against the unit's 115V, 208V, and 230V options to avoid installation delays.
- Footprint: Check exterior dimensions and weight against your floor space and load limits before delivery.
- Safety backup: Consider CO₂ or LN₂ backup and battery-backed alarms where sample-loss risk is high.
