More compute. Same power.

Shift Thermal’s FLEX™ thermal storage cuts what your cooling draws at peak and puts that power toward compute, so the same site does more work.

Call to action

Data centers want speed to power

A data center’s power is split across compute, cooling, and overhead, and new capacity is slow and expensive to bring online. Cutting the power that cooling draws at peak leaves more for compute.

Turn cooling headroom into compute

FLEX shifts cooling away from peak demand, cutting the peak draw of your cooling system. That reclaimed capacity goes straight to IT.

5–10%

more compute from your existing power infrastructure

Up to 50%

of comparable chiller thermal ride-through capacity

A new way to bank cooling

FLEX is a patented heat-exchange innovation that makes low-cost, energy-dense phase change materials perform where they normally couldn’t. It’s highly scalable and built from standard parts.

Founded in 2017

Shift Thermal was founded by two Cornell PhD engineers who joined the inaugural cohort of Innovation Crossroads, a DOE-backed program at Oak Ridge National Laboratory. FLEX is protected by patents and know-how developed over years of iteration.

The HVAC foundation

In commercial and industrial cooling, FLEX is field-deployed today, with the potential to cut energy costs by up to 50%. That foundation is what the data-center design is built from.
