Exhaust Air Purification

Exhaust Air Purification
The requirements concerning the purity of the processes are always the same – however the exhaust gases themselves are as different as the respective processes. We have a suitable fan for all possible exhaust gas treatments. Regardless of pressure, temperature, contaminant composition or concentration of the exhaust air, we have an optimum solution for you. We will provide you with a customer-specific, highly efficient solution for your exhaust gas treatment system and, above all, in the case of very strict requirements concerning chemical and thermal resistance, abrasion, absolute tightness or demands for explosion-protected versions of fans.
We also guarantee you and your customers efficiency levels of more than 80 %, thereby exceeding the targeted energy efficiency of ErP 2015. For the various exhaust air purification procedures, such as Regenerative Thermal Oxidation (RTO), Direct Thermal Oxidation (TO), Catalytic Oxidation (CO), we supply fresh air fans, process fans, bypass fans and exhaust air fans – also for particularly high volume flows. Our wide range of materials and coatings, even at high levels of corrosion such as acids and bases as well as dust and moist vapours, guarantees years of operation – around the clock of course. For the impellers and parts that come into contact with the media, not only do we use high tensile steel but also normal or high-alloyed stainless steel, nickel materials, Hastelloy as well as Grade 2 and Grade 7 titanium for special applications.
Even in combination with temperatures of up to 1,000 °C we will find a customer-specific solution for your applications. With the right sealing systems, we can guarantee explosion protection for Zone 1 (21) and Zone 2 (22) in accordance with ATEX 94/9/EC. This also includes mechanical shaft seals, stuffing boxes or contact-free turbo labyrinth seals, also using sealing gas or return systems.

Luft- und Thermotechnik GmbH – Bennecke-Kaliko
The production of artificial leather places great demands on the technical design of the exhaust gas treatment. With efficiency factors of up to 90 % in combination with Super Premium Efficiency Motors IE4, our ATEX fans surpass all requirements for energy-efficient and high-output fans, thereby guaranteeing the effective use of the installed exhaust gas treatment.
Chemisch Thermische Prozesstechnik GmbH – Lanxess Singapur
Emissions are created during the production of butadiene rubber that must not be emitted into the atmosphere without a high-capacity thermal exhaust gas treatment (RTO). To ensure that this is possible on the basis of the latest requirements, EVG Engicon Airtech supplies both the main fan as well as the by-pass fan in an ATEX version in high-alloy stainless steel. Special splitter silencers ensure compliance with strict noise levels.
Danube refinery, Hungary
Thanks to the outstanding performance of EVG Engicon Airtech in the development and delivery of process fans for the refinery, the MOL Group Hungary has also ordered the new extremely high-performance ATEX exhaust fans of its Hydrogen system with 1,250 kW of motor power at EVG Engicon Airtech. Thanks to the premium high efficiency of the EVG fans, the electrical power requirement can be almost be maintained tin spite of the performance increase of the system.
