Zenviro Tech’s Regenerative Thermal Oxidizers (RTO) feature uncomplicated, robust technology with low operating costs. Our space-saving single reactor systems treat exhaust air flows from 10,000 to 160,000 Nm³/h or 5,000 to 100,000 SCFM, depending on size, and may be deployed with multiple reactors in parallel for larger air quantities.

Advantages of Zenviro Tech RTOs

• Reliability with 99.99+% Uptime
• One Moving Part
• Very high energy efficiency despite handling large volumes of air
• Space-saving single reactor configuration
• Low operating and maintenance costs; due to smart designs and resulting low-wear.
• Can be used on exhaust air flows with a high or low concentration of pollutants
• Bakeout/Meltout mode suitable for exhaust air flows rich in organic particulates that otherwise can cause fouling

Rotating Distributor Replaces Valves

Zenviro Tech’s novel air distribution system uses a single moving part, a rotating distributor to ensure a steady, alternating flow through the different sections of the heat exchanger in the RTO. This eliminates the need for complicated valve or damper systems that present long term reliability issues. The collected air flow remains free of pressure fluctuations caused by competing valve style, as in a conventional three-tower RTO.

Zenviro Tech’s thermal oxidizers have proven to be robust, reliable and ubiquitous in many applications. More than 1,200 pre-assembled and tested thermal oxidizers have been dispatched in our institutional history into satisfied customers around the world.

Thermal oxidation achieves gas purity conversion well above 99% for VOCs, with some trade-offs in thermal NOx and CO. Based on clever process designs, Zenviro Tech is able to offer solutions that cost effectively mitigate NOx, CO and total carbon footprint through our thermal oxidizer designs.

Advantages

• ECO-friendly and energy-efficient thermal oxidation systems with the ability to utilize internal heat recovery, and/or downstream catalysts to mitigate thermal NOx, CO, and carbon footprint
• Highly modular designs that allow easy installation in days
• Designs that support rapid variation in upstream VOC loading, without obligating end user to consume excessive amounts of fossil fuels
• Designed with SIL-2 level reliability controls and logic solvers, with well thought out process hazard mitigation safeguards following industry standards

Zenviro Tech’s patented Dual Flow Wet Electrostatic Precipitator (WESP-2F) is an integrated solution for the removal of sub-micron sized particulate matter (PM10, PM2.5), acid gases, and NOx compounds from your process exhaust.

Advantages:

• Multi-Pollutant Control
• Integrated NOx Removal
• Upstream Process Flexibility
• Highest Available Removal Efficiency
• Lowest Total Cost of Ownership

The WESP-2F’s ability to effectively remove multiple pollutants in an integrated package ensures emissions compliance and maintains the flexibility to choose more affordable process feedstock/operation. Zenviro Tech has taken the proven wet electrostatic precipitation technology to a new level. The multistage design combined with integrated scrubbing zones and other proprietary features, provides performance to meet current and projected emissions regulations requirements.

Environmental requirements are every increasingly looking for tighter requirements. Plants are ever increasingly operating on higher uptime production schedules to optimize return. As such, some applications require integration of various thermal and particulate removal steps, in a solution that can be integrated in an existing site without disruption of current production. Zenviro Tech does and will supply the necessary upstream solutions for collection, PM removal, and thermal treatment systems including peripheral controls, auxiliary rotating and combustion equipment, and electrical sub-systems for applications demanding a single point of responsibility.
