VEN CLEANAIR RTO by Venjakob

Renewable Post-Combustion Systems for Industry

RTO Systems for Energy-Efficient Industrial Exhaust Air Purification

VEN CLEANAIR RTO systems are regenerative after-combustion systems designed to treat VOC-contaminated exhaust air streams. The systems are centered around ceramic heat storage media, defined switching cycles, and a system configuration tailored to the volume flow, pollutant load, and operating mode of the respective production process.

Depending on the application, various chamber designs, valve technologies, and control strategies are employed—ranging from compact system solutions to multi-stage systems for continuous production processes.

  • Design based on volume flow, VOC concentration, and process operating mode
  • Two- or multi-chamber systems with ceramic heat storage elements
  • Control and switching concept tailored to plant operation

The advantages of regenerative post-combustion systems

Regenerative thermal incineration becomes particularly important when ensuring compliance with emissions standards must not come at the expense of energy consumption. This is precisely where RTO systems excel.

High Energy Efficiency

The heat generated during the cleaning process is stored and used to preheat the incoming exhaust air. This significantly reduces the need for additional fuel.

Usable Waste Heat

When pollutant concentrations are high, excess heat can be recovered and used for other processes—for example, to support drying or heating processes.

Compact design

RTO systems can be designed to save space and integrate well into existing production environments. This is particularly important when available space or building structures are limited.

Easy to maintain

Easily accessible components simplify maintenance and service while the system is in operation. This helps ensure high availability and reduces unplanned downtime.

Safe Emission Levels

The RTO achieves a very high level of purification for VOC-contaminated exhaust air. This ensures reliable compliance with regulatory requirements.

Which VEN CLEANAIR RTO is right for your process?

Not every regenerative incineration system follows the same system design. The key factors are exhaust air volume, VOC load, operating hours, temperature profile, and the degree of consistency or variability in the production process. VEN CLEANAIR RTO systems are therefore not viewed as a rigid, one-size-fits-all solution, but rather as a product family with various technical configurations—tailored to the process, emission requirements, and energy balance.

For defined exhaust air streams with manageable volume flows and clear process parameters.

For continuous production processes in which stable flow control and high availability are paramount.

For applications in which the heat available in the system is to be specifically integrated into the production energy balance.

For processes with fluctuating VOC concentrations, varying operating conditions, or special safety and control requirements.

Plant Design Concepts for Different Production Environments

System Concepts for Different Production Realities RTO systems differ primarily in how they are integrated into the production process. Key factors include exhaust air sources, load changes, operating times, installation conditions, and whether heat is to be used solely within the system or additionally recovered. The VEN CLEANAIR RTO product family offers a variety of technical configurations designed for this purpose—tailored to real-world process conditions rather than standard values.

Not much space for the system

The VEN CLEANAIR RTO Vertical is suitable for high exhaust air volumes while requiring a reduced footprint.

Limited installation height at the installation site

The VEN CLEANAIR RTO Horizontal is suitable for applications with limited installation height or special installation requirements.

Short installation time requested

The VEN CLEANAIR RTO Compact is used atfor lower volume flows and to ensure the simplest possible integration.

High solvent content in the process

The VEN CLEANAIR RTO HD is suitable for processes involving higher concentrations of VOCs or solvents.
