We remove thermal barriers to technological progress.
Our vision.
To become the global industry standard for thermal control.
APR is a deep tech company, developing and producing high-performance distributed chip-scale liquid cooling architecture used primarily in datacenters, space, defense, telecom and batteries. The company was founded in Enköping, Sweden, in 2011 by three researchers with backgrounds in ion physics, materials physics, surface chemistry and system design. They shared a conviction: heat would become one of the most critical constraints on the future of technology. Today that conviction has proven correct, and thanks to the head start, APR already has the solution.
What sets us apart is our ability to control and redirect cooling liquid flow at chip scale level in immediate response to hotspots using solid-state technology.
The story of Rheion™.
Working in collaboration with NASA, ESA and Airbus, APR developed Rheion™. The name reflects the science. Rheo, from the Greek, means flow. Ion refers to the ion-drag mechanism through which Rheion moves fluid using electric fields rather than mechanical force. No moving parts. No pump. No wear. That same technology, designed for orbit, now addresses one of the most pressing constraints on earth. AI, power electronics and high-density compute are driving heat flux levels beyond what conventional cooling can manage. Rheion™ removes heat as a system constraint.
