Honeywell Aerospace has installed its Thermal Response Module at Equinix’s Co-Innovation Facility in Ashburn, Virginia, where Equinix tested the system for liquid-cooled AI data centres. Designed to fit into an existing cooling loop between the coolant distribution unit and servers, the module uses phase-change materials to buffer heat during power disturbances and rapid shifts in computing demand. No order value, wider rollout or deployment beyond the test facility has been disclosed.
The module is intended to stabilise coolant temperatures while the wider cooling system responds to fluctuations. Its design does not require a system redesign or a specific coolant distribution unit vendor. Honeywell says the unit can stabilise the loop within seconds and provide several minutes of buffering; the company also claims it delivers 7.6 times the cooling power of chilled water.
Equinix’s testing examined the module’s response to rapid changes in GPU cooling loads. Pawel Wlodarczak, the company’s design innovation director, reported that it occupied less space than buffer tanks. The system also incorporates heat-exchanger designs and state-of-charge sensing.
The installation brings Honeywell Aerospace’s thermal-management work into data-centre infrastructure, but the disclosed development remains a test at Equinix’s Ashburn facility rather than evidence of commercial adoption at other sites.
