Exhaust gas treatment
Hazardous gas treatment systems used in
a wide variety of fields
Sinto began releasing information about emissions of specified chemical substances for each of its business locations in 2003. The following year, Japan’s Air Pollution Control Act was revised, putting VOC emissions reduction in the spotlight. Odors have also been subject to regulations under the Offensive Odor Control Law in recent years, making it necessary to address complaints from the local community.
Sinto’s exhaust gas purification systems are low-energy, high-efficiency systems capable of decomposing VOCs and targeting odors while effectively utilizing heat energy.
Sinto offers total engineering of exhaust gas treatment systems that reduce running costs.
These systems are eco-friendly.

Eco-friendly, energy-efficient system engineering
Energy-efficient system for exhaust gas treatment
Our regenerative thermal oxidizers (RTOs) have a definitive advantage over direct-heat systems in terms of both environmental and cost performance, and running costs and environmental impact are further reduced with the addition of ancillary equipment.
The 3Rs of exhaust gas treatment
Reduce the amount of gas to be treated
Concentrators reduce volume of CO2 emissions
① VOC concentrators
Our systems can be fitted with concentrators to target high-flow, low-concentration VOC gas. By increasing the concentration of VOCs and reducing the overall airflow to be treated, this contributes to reduced fuel consumption and lower CO2 emissions.
Reuse heat energy
Heat exchangers send heat to drying lines
② Heat exchangers
Add a heat exchanger to reuse the heat from treated high-temperature gas. The hot air is perfect for supplying to drying furnaces or other drying operations, allowing for energy savings throughout the entire production line.
Recycle heat energy
Waste heat boilers recycle heat energy as steam
③ Waste heat boilers
These devices effectively recycle treated high-temperature gas by converting it to steam energy. Reducing the operation of fuel-burning boilers can result in significant CO2 reductions.
Exhaust gas purification technologies
Regenerative thermal oxidizers (RTOs) (excludes ECRs)
Organic odors and volatile organic compounds (VOCs) can be efficiently burned and decomposed at temperatures of 800ºC and higher. RTOs use a honeycomb ceramic structure for thermal storage, resulting in extremely high heat exchange efficiency. This greatly reduces running costs compared to direct-heat equipment, which requires a constant supply of fuel.
Running cost comparison between direct-heat and regenerative thermal equipment*
VOCs will self-combust at a certain concentration and combustion room temperature, making it unnecessary to supply combustion fuel. This is how Sinto is able to bring the running costs needed to decompose VOCs to zero, greatly reducing fuel consumption. It’s the perfect solution for customers looking to cut costs while reducing CO2 emissions.

Proprietary honeycomb ceramic structure
Sinto’s proprietary design maximizes contact surface area for outstanding heat exchange efficiency while supporting straight-line gas flow that minimizes pressure loss as well as tar adhesion.
