How It Works
Rotary distribution simplifies regenerative oxidation.
VOC-laden exhaust passes through ceramic heat-storage media before entering the oxidation chamber. The recovered heat reduces burner demand, while a rotary distributor continuously redirects the air stream between bed sectors.
Single-reactor, space-saving layout
Stable alternating airflow
High thermal energy recovery
Reduced switching components
Continuous treatment cycle
The distributor coordinates heat recovery, oxidation and purge functions without a complex bank of switching dampers.
1. PreheatIncoming exhaust absorbs stored heat from the ceramic media.
→
2. OxidizeVOCs are converted at the required oxidation temperature.
→
3. RecoverClean hot gas transfers energy to another media sector.
Rotary distributor: one coordinated moving component routes gas through the regenerative sections and supports smooth, reliable operation.
Modular Advantage
Designed to reduce work at site.
Major equipment, combustion components, heat-storage media, controls and internal ducting are coordinated as a factory-built package. Pre-assembly and shop testing help shorten installation and commissioning activities.
Fewer Moving Parts
Rotary distribution replaces a complicated arrangement of frequently switching valves or dampers.
Heat Recovery
Regenerative ceramic media recovers process heat to limit supplemental fuel consumption.
Factory Pre-assembly
Mechanical, combustion, fan and control systems are integrated before delivery.
Shop Verification
Defined inspection and test activities help avoid site rework and reduce commissioning risk.
Five Standard Sizes
The VL series supports industrial exhaust-air duties from 2,500 to 30,000 Nm³/h.
RTO-VL Product Range
Five modular sizes for different process-air duties.
Model selection is finalized against actual gas composition, VOC loading, inlet temperature, particulate or condensable content, required destruction efficiency and project site conditions.
| Model | Nominal Airflow | Overall Envelope (L × W × H) | Approx. Equipment Weight | Main Fan Power |
|---|---|---|---|---|
| RTO-VL800 | 2,500–8,000 Nm³/h | 9,920 × 4,000 × 7,680 mm | 16 t | 22 kW |
| RTO-VL1200 | 8,000–12,000 Nm³/h | 10,130 × 5,000 × 7,680 mm | 19 t | 37 kW |
| RTO-VL2000 | 12,000–20,000 Nm³/h | 10,050 × 6,000 × 7,860 mm | 36 t | 55 kW |
| RTO-VL2500 | 20,000–25,000 Nm³/h | 10,050 × 7,600 × 7,860 mm | 44 t | 75 kW |
| RTO-VL3000 | 25,000–30,000 Nm³/h | 11,420 × 7,000 × 8,400 mm | 57 t | 90 kW |
