Refurbishing RTO Carousel: One Complete, One Beginning

Our shop crew of extremely capable refurbishing technicians continues to bring vitality to Regenerative Thermal Oxidizer (RTO) systems in need of functional and cosmetic updates. A pair of rotary valve RTO systems are currently passing like ships in the night. One, a Durr Reeco Brand, model RL 50 (50,000 scfm) RTO has been fully refurbished and updated and is ready to ship. The other, an Eisenmann brand RTO with 47,000 scfm capacity will begin its transformation. Each is a quality built rotary valve RTO design. Each was sourced from our large (20+) RTO inventory and reconfigured by our engineering team to match our customer’s process and VOC destruction requirements. One is complete and is looking nearly new, and the other is about to begin its refurbishing journey.
