Product Overview:
The CA5000-N Liquid Nitrogen Freezer Backup System is a unique combination of a field-proven ultra-reliable alarm system and a liquid nitrogen (LN2) injection system, for safeguarding your precious biological materials and other products stored at ultra-low temperatures (ULT) in mechanical freezers. The system offers user-programmable alarm and control setpoints and alarm delay times, all stored in non-volatile memory..
The customer supplied LN2 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 LN2 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 LN2 injection from the CA5000 system will bring a mechanical freezer at room temperature to ultra-low temperatures without having to wait for the typical ULT freezer cooldown period.

The peace of mind and rapid cooling efficiency
of our CA5000-N backup systems is crucial for vaccine and mRNA
vaccine storage, virus and genetic samples, in vitro
fertilization (IVF) samples, biopharmaceuticals, and other
materials that must be stored at ultra-low temperatures.
Our CA5000-N systems are easy to program; including ULT freezer chamber target temperature, alarm delay periods, LN2 injection initiation conditions, and LN2 injection timing. For operational safety, the system includes a door interlock switch that disables LN2 injection when the freezer door is open. The CA5000-N is MADE IN THE USA at our Dover, NH facility.
Note: Hampshire Controls supplies the LN2 injection tubing from the CA5000 to the ULT freezer. Tubing between the LN2 supply and the CA5000-N must be provided by the user.
