Product Overview:

The CA5000-N system provides the ultimate in freezer backup protection for any ultra low temperature cold storage application. Not only does it provide monitoring/alarm and battery backup operation for cryogenic cold storage, it exceeds competitive system capabilities by incorporating rate-adjustable backup injection of LN2 into your freezer.

Unlike other competitive units, this system enables the end user to adjust ON/OFF backup coolant injection rates. It is shipped from our U.S. factory with default injection rate settings, however, injection rates are user adjustable.
Should a serious mechanical failure or a long-term power failure occur, the CA5000-N will activate injection cooling after a user-designated period. Once initiated, it will then inject LN2 coolant directly into your ultra low temperature freezer or cooler cabinet.

This additional capability is critical for the safe storage of genetic materials, vaccines, virus samples, IVF materials, biopharmaceuticals and other temperature-sensitive materials that must be maintained within a tight ultra low temperature range.

The system is simple to program and includes the ability to set alarm temperature conditions, alarm delay periods and backup injection initiation conditions. The system  also safely stores ALL programmed operating parameters within a non-volatile memory.
