Heat Recovery Systems

As energy costs rise, businesses are under increasing pressure to optimize energy usage and reduce operational expenses. EIS specializes in designing heat recovery systems that not only minimize energy consumption but, in some cases, transform your system into a net energy producer.

By integrating advanced heat recovery technologies into your processes, our systems can operate autothermally, eliminating the need for support fuel. With experienced engineering and seamless integration, EIS ensures that your heat recovery system delivers maximum efficiency and reliability.

Achieving optimal heat recovery requires integrated engineering that considers both your emission control requirements and your facility’s thermal energy needs. Our project management expertise ensures trouble-free integration of heat recovery systems into your process, maximizing energy recovery while maintaining emission compliance and operational reliability.

Heat Recovery

Comprehensive Heat Recovery Solutions

Primary Heat Recovery Systems

Recuperative Heat Exchangers
Shell-and-tube heat exchangers integrated directly into thermal or catalytic oxidizer systems, preheating incoming process air with hot exhaust gases. Recuperative systems achieve thermal efficiencies up to 70%, dramatically reducing supplemental fuel consumption.

Regenerative Heat Exchange Media
Ceramic or structured media beds that alternately absorb heat from hot exhaust gases and transfer it to incoming process air through cyclical flow reversal. Regenerative systems achieve thermal efficiencies of 90-98%, enabling autothermal operation in many applications.

Secondary Heat Recovery Systems

Air-to-Air Heat Exchangers
Capture waste heat from cleaned exhaust gases to preheat makeup air for facility heating or process requirements.

Air-to-Water Heat Exchangers
Transfer waste heat to water systems for facility heating, process use or domestic hot water generation.

Thermal Oil Systems
Heat transfer fluid systems that capture high-temperature waste heat for process applications requiring precise temperature control.

Waste Heat Boilers
Generate steam from waste heat for process use, facility heating or power generation through steam turbines.
