Ecopure® RL – The Ecopure® RTO with a rotary valve

The Ecopure^® RL has twelve separate ceramic heat exchanger beds that are arranged radially over a proprietary distributor valve. Incoming contaminated air enters the media beds through the base of the Ecopure^® RL and is drawn upwards through five of the beds which have been pre-heated.

The air is heated as it rises and enters a combustion chamber at the top of the system where a burner provides any additional energy needed to complete the oxidation process. The pollutants are oxidized at high temperatures and converted into CO₂ and H₂O. Hot, clean exhaust gas is then drawn downwards through the five adjacent ceramic beds where the thermal energy is transferred to the blocks before the clean air is released into the atmosphere.

The two “spare” beds help to prevent cross contamination between the inlet and outlet sections and ensure that the Ecopure^® RL unit is highly efficient. Up to 95% of the thermal energy required for the oxidation process is recovered internally which keeps the consumption of fuel by the burner to a minimum.

The Ecopure^® RL system can be used in a wide variety of industries including:

• Chemical
• Pharmaceutical
• Petrochemical
• Carbon fiber
• Food
• Composites/textiles
• Fire testing facilities
• Foundries
• Glass
• Painting and surface treatment
• Printing and coating
• Rubber/latex
• Semiconductors
• Waste treatment/recycling
• Timber

Dürr Ecopure^® RL regenerative thermal oxidizers are available in pre-fabricated sizes for exhaust gas flows from 6000 Nm³/h to 126,000 Nm³/h. They can treat exhaust gases containing pollutant concentrations from <1g/Nm³ to 10g/Nm or up to 25% LEL (lower explosive limit).The Ecopure^® RL has an efficiency level of more than 99% and can remove the following pollutants from exhaust gases in industrial processes:

• Aliphatic and aromatic hydrocarbons
• Hazardous air pollutants (HAPs)
• Odors

The compact, standardized Ecopure^® RL Air Pollution Control System, which creates a special airflow through a rotating distributor in a single container, is available in various sizes. The system consists of twelve separate ceramic heat exchanger beds, which are arranged radially above a rotary distributor valve. The Ecopure^® RL comes as standard with a state-of-the-art burner control system consisting of a burner and a patented rotor. The Ecopure^® RL is pre-assembled on transport frames and shipped in as few sections as possible to keep the installation time and costs to a minimum.
