Arctiko CO2 Backup System for Ultra-Low Temperature Freezers
Item#: CO2-BACKUPThe Arctiko CO2 Backup System is designed to enable the Low or Ultra-Low temperature freezer to maintain a safe sample storage temperature in the event of power cut or freezer fault.
An electronic measurement system continuously monitories the freezer’s interval temperature. If this temperature rises above a certain level (determined by the user), the system will inject liquid CO2 at a controlled rate to keep the cabinet cold. This action will continue until either the liquid CO2 supply is empty or the internal battery of the CO2 back up is discharged, giving time to restore power or move samples to an alternative location.
The system is powered by electric mains under normal conditions. Should the main power fail, the internal battery will continue to operate the system for several days (72 hours), providing continuous sample protection.
- Fits almost all types of Low and Ultra Low Temperature freezers (-50 °C to -70 °C)
- Safety door switch stops the liquid CO2 injection when opening the door
- Battery charging and CO2 injection active indicators
- Display of actual temperature and setpoint for injection
- Simple installation
- 2m flexible high-quality hose included
- Stainless steel case
