Feige: Research project on energy-efficient heat recovery in paint booths

A research and development project by Feige Lackieranlagen was officially recognized in January 2026. The focus is on energy-efficient heat recovery from exhaust air from industrial paint booths under high demands on process stability and particle separation.
Feige Lackieranlagen GmbH & Co. KG has successfully implemented a research and development project for high-grade heat recovery from paint-contaminated exhaust air. The starting point was the technical challenge of using exhaust air from industrial paint booths efficiently in terms of energy and at the same time meeting the high requirements for particle separation and process stability. The aim was to develop an air technology system architecture that addresses these requirements in an integrated solution. The core of the technical implementation is a further developed heat recovery system that was specifically designed for exhaust air flows contaminated with particles and solvents. The system was first developed experimentally and then optimized using simulation-based methods. In addition, optimized sealing geometries and multi-stage filter cascades were used, which are adapted to the specific flow and particle properties. Final application-related tests confirmed the suitability of the system for industrial painting applications.
High degree of heat recovery in paint booths
In this way, an overall heat recovery efficiency of at least 67% is achieved, while at the same time over 99% of the paint particles contained in the exhaust air are separated. The system architecture developed is designed to combine energy efficiency and process stability in industrial painting systems. It can be integrated into new system concepts as well as technically retrofitted into existing paint booths, taking into account the respective spatial and technical boundary conditions. The research and development character of this approach has been officially recognized by the Certification Body for Research Grants (BSFZ). The recognition confirms Feige Lackieranlagen's claim to develop technically sound and at the same time future-proof solutions in which sustainability and technical feasibility are an integral part of the planning right from the start. Feige Lackieranlagen will be exhibiting at PaintExpo 2026 in Hall 2129.
