TankGuard Automatic CO2 Incubator Tank Switch

The TankGuard automatic tank switch ensures uninterrupted gas supply for cell culture incubators, automatically switching between CO2/N2 tanks and alerting on changes for optimal research continuity.


Engineered for precision and reliability, the TankGuard automatic tank switch is an essential tool for tissue cell culture incubators, ensuring a consistent supply of critical backup gases like CO2 and N2. It effectively monitors and indicates the active source gas tank while keeping tabs on the status of the secondary tank. Should the primary tank's pressure drop below 8 PSI, the TankGuard intuitively switches to the alternate tank, with an internal pressure switch facilitating this automatic transition. An audible alarm signals the change, while LED indicators display the new source status and the depletion of the original tank. Simple to install with hose barb connections, this switch is a vital component for NuAire CO2 Incubators, seamlessly maintaining gas supply and safeguarding hours of research against unexpected disruptions.

Automated Gas Supply Management

The NU-1550 TankGuard automatically switches between primary and secondary CO2 or N2 gas tanks, ensuring a constant gas supply for cell culture incubators. Researchers can enjoy uninterrupted experiments and maintain the integrity of their cell cultures. This automation reduces the need for manual monitoring, allowing more time for focused research and less worry about gas supply continuity.

Intelligent Pressure Monitoring and Alert System

Equipped with an intelligent internal pressure switch, the NU-1550 detects low pressure in the primary tank and seamlessly transitions to the secondary tank. It also features audible alarms and visual LED indicators for empty tanks. This system provides real-time updates and alerts, ensuring immediate awareness of gas levels. The clear indicators minimize the risk of unexpected gas depletion, ensuring a stable and controlled incubation environment for sensitive cultures.

Easy Installation and User-Friendly Operation

The NU-1550 is designed for easy installation, connecting to tank tubes via hose barbs. Its user interface is straightforward, making it accessible even for those with minimal technical expertise. Labs can quickly set up and integrate this tank switch into their existing systems without requiring extensive training or complex procedures. The ease of use ensures a smooth, hassle-free operation, enhancing the overall efficiency of the laboratory workflow.
