Product Overview:
The CA5000-C Liquid CO2 Freezer Backup System is a unique combination of field-proven, ultra-reliable alarm systems and a liquid CO2 injection system for safeguarding your precious biological materials and other products stored within an ultra-low temperature (ULT) mechanical freezer. The system works with any mechanical ULT freezer and offers user-programmable alarm and control setpoints, and alarm delay times, all stored in non-volatile memory.
The customer-supplied liquid CO2 is maintained at high pressure, ready to be injected into a failing ULT freezer cabinet. When a power outage or freezer malfunction occurs and the freezer warms above the user-defined setpoint, an alarm sounds along with a flashing red LED. If the freezer continues to warm, then a user-defined quantity of liquid CO2 is injected into the freezer, quickly restoring the temperature below the setpoint.
In addition to providing insurance against power outages and freezer malfunctions, a manual CO2 injection from the CA5000-C system will bring a freezer at room temperature to ultra-low temperature without having to wait for the typical ULT freezer cool down period.
NOTE: Click here for our model CA5000-N if you need controllable liquid nitrogen (LN2) backup injection for your ULT freezer system.
Our CA5000-C systems are easy to program,
including ULT freezer chamber target temperature, alarm delay
periods, CO2 injection initiation conditions, and CO2
injection timing. For operational safety, the system includes
a door interlock switch that disables CO2 injection when the
freezer door is open. The CA5000-C is MADE IN THE USA
at our Dover, NH facility.
Note: Hampshire Controls supplies the tubing from the CA5000-C to the ULT freezer. Tubing between the CO2 supply and the CA5000-C must be provided by the user, or, purchase our A84000-19 CA5000-C Liquid CO2 Backup System Installation Kit.
