Dürr Systems, Inc.

Environmental solutions for the engineered wood products - Forestry & Wood

The engineered wood products industry relies on Dürr Megtec for regenerative thermal oxidizer (RTO), regenerative catalytic oxidizer (RCO), wet electrostatic precipitator (WESP), dry electrostatic precipitator (DESP), and wet scrubber technologies for effective emissions control of volatile organic compounds (VOCs), hazardous air pollutants (HAPs), particulate matter (PM), and blue haze from wood dryers and press vents. As an industry leader, we offer a comprehensive suite of advanced air pollution control products.

Dürr Megtec is a leader in providing regenerative thermal oxidizers (RTOs) for VOC/HAP control for products such as OSB, MDF, HDF, SYP, plywood, particleboard, veneer, wood pellets, and other composite wood products, with particular expertise in solving the problems of media plugging and alkali attack associated with wood dryer exhaust.

With thousands of systems installed in process industries worldwide, Dürr Megtec has the knowledge to provide the best solution for your specific needs. Our modular and low maintenance design, use alkali-resistant ceramics, and corrosion-resistant materials of construction.

Dürr Megtec provides rebuild services for upgrading or modifying existing equipment. A typical modification would be rebuilding a regenerative thermal oxidizer into a regenerative catalytic oxidizer (RCO). A rebuild from an existing RTO to RCO may result in the unit conforming to EPA guidelines, as well as meeting plant-specific permit levels at an operating temperature below the operating set point temperature of the previous RCO. A rebuild can restore environmental performance and reduce operating costs.

Our commitment to the wood products industry is proven with the availability of a pilot unit RTO for testing slip-streams of your process to determine the optimal pre-filtration (cyclone, dry electrostatic precipitator (DESP) or wet electrostatic precipitator (WESP) and RTO bed design.

With our extensive air handling experience, we can also provide services to reduce fugitive emissions, control process exhaust flow rates, and improve the overall efficiency of your VOC capture systems.

Dürr Megtec technologies are used throughout the wood products industry to effectively remove fumes and sticky particulate from energy systems, dryers, and press vents. Our systems are designed for minimum maintenance, while allowing the user to meet stringent emissions regulations, including the U.S. EPA Plywood and Composite Wood Products (PCWP) MACT rules.

The Dürr Megtec wet ESP removes sub-micron particulate (including back half salts, tar-pitch and fiber) and fumes from dryer and energy system gas streams. Our hex-shaped tube design delivers the best combination of removal efficiency, low maintenance, low-pressure drop and small footprint. Our venturi scrubber and Turbotak atomizing scrubber provide gas stream saturation and high-efficiency (front and back half) particulate removal as a stand-alone or in front of the WESP.

Dürr Megtec WESP upgrades bring facilities with existing air pollution control equipment into compliance. These upgrades eliminate carryover and costly maintenance by utilizing patented and proprietary solutions. Improvements to T/R sets, water treatment systems, gas flow distribution, and mist elimination all help improve performance, reduce operating costs, and protect downstream equipment.
