By eliminating air cooling entirely and improving thermal transfer efficiency, immersion cooling has the potential to radically reshape how data centers are operated.
Unlike traditional air-cooled systems, immersion cooling completely submerges servers directly into a dielectric fluid. This non-conductive, thermally stable liquid draws heat away from critical components, efficiently transferring it to a secondary loop that rejects the heat outdoors via a cooling tower or fluid cooler.
At the heart of this innovation is the dielectric fluid itself. This specialized fluid enables submersion cooling to work safely, affordably, and with minimal maintenance. Learn more about Dielectric Fluids.
BAC’s new COBALT™ Immersion Cooling System delivers unparalleled energy efficiency, system reliability, and optimized power use. Powered by patented CorTex™ Technology, the COBALT Immersion Cooling System provides the lowest Power Usage Effectiveness (PUE) solution at <1.05.
- No leak design
- Smaller installed footprint

BAC’s immersion cooling tank patented leak-free design has no penetrations below the fluid level, ensuring fluid integrity and system reliability.
Dual pumps provide redundancy, while the sealed, filter-free configuration simplifies operation and eliminates routine maintenance.
The tanks are now offered in multiple sizes — 16RU, 32RU, 38RU, and 48RU — allowing data centers to maximize rack density and accommodate a wide range of immersion-ready servers. Designed to support server widths of 19” and 21” and depths up to 1200 mm, each tank meets diverse infrastructure needs while maintaining a compact footprint compared to traditional air-cooled systems.
