Engineering & Consulting Services for Energy Technologies
Where Deep Engineering Expertise Meets Real-World Energy Challenges
Flue gas cooling and waste heat recovery
Capturing waste energy to lower the cost of carbon capture
At LJUNGSTRÖM, our Engineering and Consulting Services are built on nearly a century of thermal science innovation. Today, we apply that legacy to the world’s most pressing energy challenges—waste heat recovery, flue-gas cooling, fuel switching, and carbon capture, utilization, and storage (CCUS)—helping power producers, industrial operators, and emerging energy sectors optimize efficiency, reduce emissions, and modernize their operations for a low-carbon future.
Our team of engineers, thermal modeling experts, and field specialists delivers end-to-end support—from early-stage feasibility to detailed design, implementation, testing, and long-term performance optimization.
