At BM Process Management, we provide engineered solutions for thermal exhaust air purification, working with cutting-edge technologies from our long-standing partner Krantz. Together, we offer high-performance Regenerative Thermal Oxidizers (RTOs) tailored for VOC-emitting industries, combining efficiency, reliability, and ease of integration.
Krantz RTO systems are built around ceramic heat regenerators that recover and retain up to 96% of the thermal energy within the system. By reversing the airflow between hot clean gas and cooler exhaust air, these systems can operate autothermally at VOC concentrations of just 1.5 g/Nm³, reducing or even eliminating the need for additional energy input from fuels or electricity.
When inlet VOC concentrations are higher, the excess heat can be harvested and reused for generating process heat, significantly improving the overall thermal efficiency of plant operations.
We offer flexible configurations—2-chamber, 3-chamber, and multi-chamber setups—to match varying industrial needs and emission levels.
Krantz’s tried-and-tested oxidizers—Regetar and Tarmin—have been continuously optimized since 1990. Their robust design ensures high system uptime and long service life.
• Proprietary buffer technology enables lightweight, economical 2-chamber systems.
• Development of CO₂-neutral solutions is underway using hydrogen-enriched exhaust streams.
• Introduction of SmartRTO E, a fully electric RTO variant for clean energy applications.
Krantz’s SmartRTO series offers compact, pre-assembled systems ideal for fast-track projects and retrofits. Available in capacities of 5,000 to 20,000 m³/h, these systems are delivered ready-to-operate—simply unload, connect, and start purifying.
Configurations include:
• 2-chamber units (with or without buffer)
• 3-chamber systems for broader VOC range handling
Another innovation is the combination of the smartRTO technology with electrical heating. This enables customers to implement fully electrified exhaust air treatment in a fast and efficient manner. No need for natural gas connections, no additional CO2 emissions and no additional NOx emissions. Smart, fast and efficient.
