Thermal Transformer – De-electrified cooling

Thermal Transformer’s technology

Thermal Transformer‘s technology is built on decades of research and hands-on experience in thermal management at leading high-performance computing and energy research facilities. Instead of adding even more electrical demand for cooling, we unlock a new resource that is already there: the waste heat your systems produce every day. We offer a scalable path to meet the world’s rising demand for cooling — while significantly reducing the reliance on additional electricity.

AI boom: Swiss concerned about electricity usage

In Switzerland the boom of AI computer centers is an important concern for the population. In a survey the majority expressed concerns and supports that new data centers only can be built using renewable energy. Thermal Transformer will address this convern by reducing the energy hunger of the data centers by heat driven adsorption cooling that saves 30% of the electricy vs traditional cooling.

AI data centers: cooling is the hidden energy cost

As AI workloads grow, so does the energy needed to keep servers within safe operating temperatures. In many facilities, up to 30% of total power consumption is used just for cooling. At the same time, even with growing efficiency efforts, most low-grade waste heat from water-cooled racks is still not fully utilized.

Thermal Transformer changes this balance. Our system uses the waste heat from water-cooled racks to provide cooling for the rest of the data center infrastructure — storage, communication racks, and auxiliary systems.

Less electrical power needed for cooling
Better overall energy utilization
A more sustainable, future-proof cooling strategy for AI-ready data centers

Industrial cooling need

In industrial plants, gas compressors are essential — and they generate large amounts of low-grade waste heat. Today, much of this heat is simply discharged to the environment.

Thermal Transformer enables a different approach: We use the waste heat of industrial gas compressors to produce cooling, for example to precool the suction gas or serve other cooling demands on site.

Improve overall energy efficiency
Reduce electrical demand for compressors
Make better use of existing thermal assets instead of installing entirely new systems

Next-generation adsorption heat pump technology

At the core of Thermal Transformer is a new generation of adsorption heat pump technology, engineered specifically for low-grade waste heat and compact, high-performance operation. Our system is designed to:

Operate at significantly lower driving temperatures than conventional adsorption systems
Deliver a specific power density 2–3× higher than comparable solutions
Integrate with modern water-cooled rack systems and industrial heat sources

This combination makes it possible to unlock cooling from waste heat in places where traditional thermally driven cooling has not been viable before.
