Achieve mission-critical uptime with compressor-free thermoacoustic cooling that eliminates failure points for data centers seeking 99.999% reliability.
In the world of mission-critical data centers, uptime is the ultimate metric. Achieving "five nines" (99.999%) availability—equivalent to just over five minutes of downtime per year—requires eliminating every potential point of failure.
While power and network redundancy are well-understood, cooling systems remain a critical vulnerability. Traditional vapor-compression cooling, with its reliance on mechanical compressors, pumps, and complex refrigerant cycles, is fraught with failure points that can lead to catastrophic thermal shutdowns. Thermoacoustic cooling offers a fundamentally more reliable alternative, engineered for the resilience that mission-critical facilities demand.
Thermoacoustic cooling eliminates the mechanical failure points that threaten data center uptime
In a multi-driver thermoacoustic array, the failure of one acoustic driver results in reduced capacity—not a total shutdown. This built-in fault tolerance provides an additional layer of resilience for mission-critical operations.
A thermoacoustic chiller operates on a principle of elegant simplicity. It uses a powerful, precisely controlled sound wave inside a sealed resonator to create a temperature differential. An inert working gas, such as helium, oscillates through a porous stack, where the heat exchange occurs without any moving parts in the thermodynamic cycle itself.
This thermal energy is then transferred to the data center's liquid cooling loop via robust heat exchangers. By removing the mechanical compressor—the number one failure point in traditional cooling—the system's intrinsic reliability is dramatically increased.
Compressor-free design eliminates the #1 failure point in traditional cooling systems
For data centers powering financial services, healthcare, or cloud computing, even minutes of downtime can result in millions of dollars in losses. Thermoacoustic cooling provides the robust, reliable foundation needed to support these mission-critical operations. Its inherent fault tolerance and low maintenance profile ensure that the cooling system is no longer the weakest link in the chain of availability. Cool Sound Industries, Inc., has been the thermoacoustic industry leader since 1996.
Higher MTBF than compressor-based systems
Reduction in maintenance requirements
Mechanical compressors to fail
The primary benefit for data centers is the unparalleled reliability that comes from a compressor-free design. This directly translates to a lower risk of unplanned downtime and a stronger foundation for achieving 99.999% uptime. The system's graceful degradation—where the failure of one acoustic driver in a multi-driver array results in reduced capacity, not a total shutdown—provides an additional layer of resilience. While the technology is advanced, its core simplicity leads to significantly lower maintenance requirements. The main tradeoff is that the technology represents a shift from traditional mechanical systems, requiring facility teams to be trained on its operation, though its operational simplicity makes this transition straightforward.
Compared to Computer Room Air Handlers (CRAH) or chillers that rely on centrifugal or screw compressors, thermoacoustic systems have a mean time between failures (MTBF) that is orders of magnitude higher. They are also immune to the common failure modes of traditional systems, such as refrigerant leaks, compressor seizures, or oil circulation problems. This makes them an ideal choice for Tier III and Tier IV data centers where fault tolerance is a primary design requirement.
