Heat recovery in nitriding
ProjecT NITROTES
Together with the Leibniz Institute for Materials Engineering (IWT), we are developing NitroTES - a high-temperature thermal energy storage designed to capture and reutilize process heat from the afterburner of industrial nitriding furnaces.
NitroTES targets the first integrated demonstration of high-temperature waste-heat storage for nitriding applications. The project explores how thermal energy from the afterburner can be effectively recovered and redeployed to stabilize temperatures in downstream heat-treatment steps, thereby reducing external energy demand without compromising process quality.
Project start: May 2025 Duration: 18 months Project costs: ~ 582 k€ (70% publicly funded)
Electrifying brick manufacturing
Project eluzi
Together with KELLER HCW, the Institute for Brick Research Essen (IZF), and Jacobi Dachziegel, Heatrix is developing and demonstrating the application of a Heatrix system for delivering heated air up to 1300 °C within a tunnel oven for brick manufacturing
The project aims to validate the feasibility of replacing one burner group with Heatrix’s electric air-heating technology, without changing the kiln structure or compromising product quality. This pilot installation serves as a first step towards enabling carbon-neutral operation in energy-intensive firing processes and provides practical insights for future fuel-switch strategies in the ceramics industry.
Project start: May 2025 Duration: 24 months Project costs: ~ 1,5 M€ (67% publicly funded)
This project is funded by the German Federal Ministry for Economic Affairs and Energy (BMWE) under the grant number: 03EN2132A
Simulation of carbon-neutral energy systems
Project Simuheat
Together with the BIBA - Bremen Institute for Production and Logistics, Heatrix is developing an advanced simulation tool for the design and optimization of carbon-neutral energy systems for energy-intensive industries.
SimuHeat focuses on the development of a digital twin environment that enables the simulation, optimization, and economic evaluation of hybrid renewable energy systems integrating electric heaters, thermal storage, and fluctuating renewable power. By combining real production and weather data, the tool identifies cost-efficient and climate-friendly energy configurations, supporting industrial users in planning their transition toward full electrification.
Project start: April 2025 Duration: 18 months Project costs: ~ 320 k€ (78% publicly funded)
Decarbonized industrial heat will lead us into the future of production.
