What Affects RTO System Cost? Key Project Factors
RTO system cost is not decided by airflow alone. Price changes with exhaust data, safety configuration, heat recovery requirement, material selection, automation level, supply scope and installation boundary.
Airflow and concentration define the base size
Airflow influences equipment body size, valve diameter, fan selection and duct connection. VOC concentration influences combustion load, fuel consumption, safety design and possible heat recovery.
A larger airflow with very low concentration can sometimes be more expensive to operate than a smaller high concentration exhaust stream.
- Total airflow and each exhaust source.
- Normal and peak VOC concentration.
- Expected pressure drop and fan power.
- Operation schedule and production fluctuation.
Safety configuration changes cost
Industrial VOC treatment equipment should not remove safety items to reduce price. LEL monitor, purge sequence, burner protection, emergency bypass and PLC interlocks all add cost, but they reduce operational risk.
For export projects, electrical standard and gas train configuration can also change the price.
- LEL detection and alarm logic.
- Fresh air dilution or bypass damper.
- Explosion relief or pressure relief where applicable.
- PLC, HMI and remote monitoring functions.
Material and corrosion requirements
If the exhaust contains corrosive compounds, high humidity or high temperature, material selection and insulation design need special review.
Stainless steel parts, corrosion-resistant coating or special seals can increase cost but may be necessary for service life.
- Solvent composition and possible acid gas.
- Moisture and dew point risk.
- Operating temperature and outdoor installation condition.
- Local climate and anti-corrosion requirement.
Supply scope must be compared carefully
A low quotation may exclude fan, duct, platform, insulation, electrical cabinet, installation guidance, commissioning or spare parts.
Buyers should ask every supplier to list the same scope before comparing.
| Scope item | Check before comparing price |
|---|---|
| Main equipment | Chambers, valves, ceramic media, burner and support frame. |
| Electrical | PLC cabinet, HMI, instruments, cable scope and signals. |
| Site work | Ducting, crane, foundation, platform and installation labor. |
| Service | Commissioning, training, documents and spare parts. |
FAQ
What project data should be prepared before asking for quotation?
At minimum, prepare airflow, VOC concentration, solvent or VOC composition, exhaust temperature, humidity, dust or mist content, operating hours, emission limit and installation location. Without these data, suppliers can only give a rough direction.
Can SERNO provide only equipment or a complete system?
SERNO can discuss different supply scopes, from main equipment to a more complete package with duct interface, safety controls, electrical cabinet and engineering support. The final scope should be confirmed in the quotation boundary.
Can SERNO give a quick budget price?
Yes, but the budget price is only meaningful after airflow, concentration, solvent type and supply scope are clear. A final quotation requires more detailed project data.
Need a practical VOC treatment recommendation?
Send SERNO your airflow, VOC concentration, solvent composition, temperature, humidity, operating hours and emission target. We can help compare RTO, Rotor RTO, RCO and catalytic combustion options before budget quotation.
