BAC upgrades immersion cooling tank
10th October 2025
USA: Baltimore Aircoil Company (BAC) has release enhanced versions of its immersion cooling tank designed for high-performance data centres.
The tank is employs BAC’s CorTex technology – a leak-proof design where cool water circulates through coils and plates to capture heat from a dielectric fluid without the two fluids mixing. 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 – designed to support server widths of 19in and 21in, and depths up to 1200 mm. The tank helps deliver a PUE of up to 1.05.
Air-cooled servers can also be retrofitted for immersion cooling.
BAC’s immersion cooling tank is the indoor cooling solution of BAC’s Cobalt immersion cooling system, which is a complete indoor and outdoor cooling system for high-density computing.
When paired with BAC’s full range of outdoor cooling solutions including — evaporative, hybrid, adiabatic, and dry systems — the Cobalt system becomes a complete data centre cooling system.
