Why ERG Yurcent?
ERG Yurcent combines ERG’s four decades of air pollution control engineering with Yurcent’s third-generation rotary RTO technology, delivered through an exclusive partnership for the UK, Ireland, Europe and the Middle East. This gives operators direct access to proven rotary RTO and VOC concentration systems, supported by local engineering expertise.
Projects are approached from a process-led engineering standpoint, ensuring systems are correctly sized, robustly designed and aligned with real operating conditions. Support spans the full lifecycle, from initial design and equipment supply through installation, commissioning, optimisation and long-term maintenance.
Built on standardised, high-performance RTO and concentrator platforms, each system can be tailored to specific flowrates, VOC compositions and regulatory requirements. The result is reliable compliance with stringent VOC and HAP limits, combined with high thermal efficiency, reduced fuel consumption and meaningful progress toward decarbonisation and ESG targets.

-
Deliver turnkey VOC abatement systems – from capture to stack
-
Provide project design, engineering, installation and commissioning
-
Offer long-term maintenance, optimisation and spare parts support
-
Help operators meet tightening emission limits while reducing lifecycle cost and energy use
Third-Generation Rotary Valve RTO Technology
Short intro:
Yurcent’s third-generation rotary valve RTO is a compact, high-efficiency solution for treating VOC-laden exhaust gas streams with high reliability and excellent heat recovery
Key benefits:
-
Ultra-high destruction efficiency
Up to 99.5% VOC destruction efficiency across a wide range of organic compounds -
Exceptional heat recovery. Up to 97% thermal efficiency, significantly reducing auxiliary fuel consumption and operating cost.
-
Rotary valve design. A continuously rotating valve distributes flow through 8–12 regenerative chambers, simplifying the flow path and providing stable temperature, low pressure drop and compact footprint.
-
Robust, standardised construction. Rotary RTO systems are built in a modern, high-capacity manufacturing facility with batch production, strict QA and ISO-certified quality management.
-
Digital safety & control. Advanced control systems monitor LEL, pressure, temperature and flows to keep operation safe, efficient and fully traceable for compliance.
Integrated VOC Solutions – RTO + Zeolite Rotor + Capture
For large-volume, low-concentration VOC exhaust streams, ERG Yurcent provides fully engineered systems that combine:
-
Rotary RTOs for final destruction of concentrated VOCs
-
Zeolite molecular sieve rotors to concentrate dilute VOC streams by 10–20×, reducing air volume and enabling smaller RTO packages
-
Air reduction and optimisation systems that lower total exhaust volume while increasing VOC concentration safely
-
Capture systems for both local equipment extraction and fugitive emissions, including oven exhausts, ducting, hoods and unorganised extraction from workshops
This integrated approach:
-
Cuts CAPEX and OPEX by optimising airflows
-
Improves energy efficiency with steam, hot water, thermal oil or hot air heat recovery option
-
Ensures stable negative pressure and safe VOC concentrations through advanced sensing and interlocks
Rotary Concentrators (VOC Adsorption & Concentration)
High-Efficiency Concentration for Low-VOC Exhaust Streams
The Yurcent Rotary Concentrator is designed to treat large-volume, low-concentration VOC exhaust gas by adsorbing VOCs onto a rotating molecular sieve and concentrating them into a much smaller, higher-strength stream for final destruction in a downstream RTO.
How the Rotary Concentrator Works
The rotary concentrator wheel is continuously rotated through three dedicated zones:
-
Adsorption zone
Low-concentration exhaust gas passes through the adsorption section, where VOCs are captured by the molecular sieve media. The cleaned air is then discharged directly to atmosphere. -
Desorption (regeneration) zone
Once the media becomes saturated, it enters the desorption zone and is regenerated using a small flow of hot air (typically 180–220 °C). The captured VOCs are released into a reduced air stream, creating a high-concentration exhaust. -
Cooling zone
The media then passes through a cooling zone before returning to the adsorption zone, allowing continuous operation with stable performance.
This continuous rotation enables steady VOC removal, regeneration and reuse of the adsorption media without interruption.
Performance & Key Benefits
-
VOC concentration ratio: typically 10–20×
-
Overall purification efficiency: 95–98%
-
Single-unit airflow capacity: 1,000 – 200,000 m³/h
-
Continuous, stable operation with low pressure drop
-
Reduced RTO size and fuel demand due to lower treated airflow
By concentrating dilute VOC streams, the rotary concentrator significantly reduces the size and energy consumption of the downstream RTO system.
Integration with Rotary RTO Systems
The concentrated VOC stream produced by the rotary concentrator is ideally suited for treatment in a Yurcent rotary valve RTO, forming a highly efficient combined solution:
Low-concentration exhaust → Rotary Concentrator → High-concentration VOC stream → Rotary RTO
This integrated approach delivers:
-
Lower CAPEX through smaller RTO sizing
-
Reduced OPEX via improved thermal efficiency
-
Improved overall system controllability and safety
Applications & Customisation
Yurcent rotary concentrators are suitable for a wide range of low-concentration VOC applications, including:
-
Coating lines
-
Printing and packaging
-
Surface treatment and finishing
-
Electronics and light manufacturing
Depending on the industry, VOC composition and operating conditions, Yurcent selects appropriate adsorption media and designs the concentration ratio and system parameters to ensure reliable compliance with emission limits.
Across multiple industrial references, Yurcent rotary concentrator systems have consistently achieved stable, compliant exhaust emissions, earning strong feedback from operators.

Proven Projects & Performance
Yurcent has delivered large, fully integrated VOC treatment systems for major packaging and printing operations, combining air reduction and concentration systems across multiple printing presses with high-capacity zeolite rotors treating over 100,000 m³/h of fugitive exhaust. Organised exhaust streams of up to 200,000 m³/h are treated using multiple rotary RTOs operating in parallel, with waste heat recovered as steam to supply several tonnes per hour back into the production process.
In operation, these systems consistently achieve total hydrocarbon emissions below 30 mg/m³, meeting stringent Class A limits. Significant reductions in purchased steam and fuel consumption are realised through effective heat recovery from the RTO system, improving overall plant efficiency. Performance and reliability are supported by centralised supervisory control, with upper-level computer systems and mobile app monitoring providing real-time visibility and remote oversight of all rotary concentrator and RTO units.
