Accelsius has announced an 18,000-square-foot expansion of its manufacturing and testing laboratory located at 8301 Springdale Road in Austin. The company, founded in 2022, is scaling its infrastructure to support increasing demand for data center thermal management.
Why it matters
As data centers face intensifying cooling requirements, Accelsius is scaling its testing capabilities to handle multi-megawatt power loads. The expansion addresses regional demand for efficient thermal solutions in high-compute environments.
The expanded laboratory at 8301 Springdale Road is designed for multi-megawatt power level testing using direct-to-chip liquid cooling. This methodology uses a closed-loop system to circulate coolant directly to the hottest components to displace heat more efficiently than air cooling.
The players
Accelsius
A 2022 startup that develops and manufactures direct-to-chip liquid cooling systems for high-performance computing.
EdgeConneX
A data center operator currently building a campus in Bastrop County and managing existing operations in Houston.
Dell
A major server and systems manufacturer utilizing Accelsius cooling technology at its Customer Solutions Center in Round Rock.
The details
The facility focuses on direct-to-chip cooling, where coolant is piped to cold plates mounted on high-power processors. By utilizing warm-water cooling systems, the infrastructure allows for more efficient heat extraction compared to traditional computer room air conditioning. These systems are currently deployed at local sites such as the Dell Customer Solutions Center in Round Rock.
Timeline
Accelsius was founded in 2022.
The company secured $65 million in funding earlier this year.
The lab expansion was formally announced on October 12, 2026.
Construction is expected to be completed in January 2027.
The Tech Race
The expansion places Accelsius at the center of the regional race to support cooling-intensive high-compute clusters in Texas. It follows the industry-wide pivot toward liquid cooling as data centers, including those by regional players like EdgeConneX, move toward higher power density.
This facility expansion accelerates the development of cooling technology required for next-generation data centers in Central Texas. While the lab is for research and testing, local operations like the Dell Customer Solutions Center may see faster integration cycles for thermal management systems.
The takeaway
Accelsius is scaling its testing footprint to meet the growing thermal load of modern high-density processors. Readers should watch for the lab's operational status in January 2027 to see if the expansion successfully accelerates testing throughput for the local data center ecosystem.
