Additional Information

N/A 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, safeguarding your precious biological materials and other products stored at ultra-low temperatures (ULT). The system 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 system will bring a freezer at room temperature to ultra-low temperature without having to wait for the typical ULT freezer cooldown period.

The peace of mind and rapid cooling efficiency of our CA5000 backup systems is crucial for vaccine and mRNA vaccine storage, virus and genetic samples, biopharmaceuticals, and other materials that must be stored at ultra-low temperatures.
