News and Announcements

January, 1, 2011 Product Release. Hampshire Controls Introduces It's New Model CA5000-N LN2 Backup Alarm System.

The Model CA5000 N Freezer Monitor Alarm Backup System is a Unique Combination of the Field Proven, Ultra-Reliable Alarm Backup Systems Now Available - But with a Liquid Nitrogen (LN2) Injection System. The CA5000 Injects Carbon Dioxide (CO2).

The CA5000 N provides even greater security for products stored in ultra-low temperature freezers. It also offers user-programmable alarm and control set points & alarm delay times. All parameters are stored in non-volatile memory - so they are maintained even when power is lost.

Customer supplied liquid nitrogen (LN2) is ready for injection into the freezer chamber should a
malfunction occur that would allow the freezer to warm above its user-defined "safe storage" set points. A user-defined amount of LN2 is automatically injected into the freezer when this happens in order to maintain safe laboratory storage temperatures and storage safety.

The CA5000 N is very simple to operate; simply plug in the unit, place the probe in the freezer chamber to be monitored, and the display will show the temperature of that location.

FEATURES:
* An internal battery with charger keeps the alarm running for at least 24 hours after a power outage.
* "BAT" indicator warns of a disconnected or low backup battery condition.
* Backup time of at least 48 hours on one 65 liter cylinder of LN2 at -65°C set point.
* Independent user-programmable controls for system alarms and LN2 injection.
* Visible and audible indicators for system status.
* Multiple programmable alarms available to minimize nuisance or false alarms.
* Relay output for central alarm systems or automatic dialers.
* A door safety interlock switch prevents LN2 injection while freezer is being accessed.
