Clean air systems - Import export

International patent registered for the CLEAN ROOM SYSTEM line (DIN EN ISO 14644-1) The CLEAN ROOM SYSTEM units are linear actuators with belt driven transmission and are specifically designed for Clean Room applications They are supplied with a certificate issued by the IPA Fraunhofer Institute in Stuttgard, which certifies compliance with class ISO 3 (DIN EN ISO 14644-1), or with class Fed Std 0.01 (FED 209 E). The system prevents particles from being discharged in the environment where the linear unit is located. This has been achieved by using a special straight seal that closes the horizontal opening where the slider moves, as well as by the operation of a 0.8 vacuum pump connected to 2 vacuum pipes located inside the drive head and the idle head. The system allows vacuum to be generated inside the unit so that any particles released when the system is operating are sucked towards the air filtration areas. Clean Room System linear actuators components are all made of...

Biological exhaust air cleaning is always required if exhaust air needs to be purified of volatile organic components the socalled VOCs or odorous substances. The demand for biological procedures has increased in recent years. On the one hand, biological exhaust air cleaning does not generate any climaterelevant greenhouse gases. On the other hand, it meets all legal requirements for clean gas values. With over 200 biological exhaust air cleaning processes installed, Wessel has comprehensive practical knowhow and is the technology leader in the field of biological exhaust air cleaning. The biological exhaust air cleaning systems have been continuously optimised and further developed by WesselUmwelttechnik for decades. The modern cleaning systems from WesselUmwelttechnik work efficiently. Thanks to the continuous monitoring of the plant parameters, they require only a minimum of operating effort.

For its exhaust gas purification systems, Venjakob Umwelttechnik offers heat exchanger systems for utilizing the waste heat. These are characterized by: We build complete heat exchanger systems for heating water, steam, air, and gas or heat transfer fluid. The residual or excess energy contained in the clean gases of the Venjakob exhaust air cleaning systems often has sufficient potential to effectively support the actual production process, the building heater or other energy consumers. Whether as an individual system for heat transfer fluid, warm and hot water, hot air, and vapor, or combined as a downstream system solution for an exhaust air purification system - the planning, construction and production of the plant are done on an individual basis.

The adsorption system (AD) from Venjakob Umwelttechnik serves to concentrate exhaust air flows containing low concentrations of pollutants, and is particularly suitable for removing extremely low to medium concentrations of solvent-based pollutants (VOCs). This machine is characterized by: During the adsorption process, the pollutants are physically retained on the surface of a solid material (e.g. activated carbon, zeolite). The pollutants are then removed /desorbed from the zeolite by means of a small, hot stream of air. Afterwards, the flow of exhaust air from the desorption process is cleaned by means of an exhaust air cleaning system (TI, RTO, CTO). By reducing the volume and by increasing the concentration, the operating costs of the downstream exhaust gas purification system can be kept very low and make autothermal operation possible among other things The rotor is mounted vertically on a shaft with bearing and rotated slowly in the air flow. During rotation, the adsorption and desorption take place simultaneously in separate chambers with cooling on a hydrophobic (water-repellent) incombustible zeolite material. For tough applications, versions can be provided with a removable wear layer and / or higher temperatures of up to 300 ° C for desorption. Two containers are operated alternately. While one of the containers is adsorbing, the other container can be desorbed The adsorption process can be used for smoothing pollutant concentration peaks. If pollutant peaks occur during a process that could lead to a potentially explosive mixture (> 25% lower explosion limit), they cannot be introduced into an incinerator. However, the pollutants may be temporarily stored in an adsorber and then be released during the desorption phase. In certain situations, the installation of an additional fixed bed adsorber (molecular sieve) may further enhance the process (safety, operating costs).

Exhaust air purification and heat recovery systems are generally not standard applications, even if individual assemblies are now modular. We have made it our goal to offer our customers the best solution for their task. To do this, we take a step back with our customers in order to gain an overview of the whole. Together we look at how the exhaust air is generated and try to start our concepts right at the point of origin. Only then can we decide which exhaust air system is the most economical when considering the total cost of ownership and compliance with the limit values. Should an extended consideration be necessary, we can accompany you from basic to authority to detail engineering. In addition, it is not uncommon for pilot tests to be offered, which lead to the later real scale of the systems by means of scaleup. With these consulting and engineering services, we offer you a manufacturerindependent package with which you can make the right decision for your company.

In many incineration and industrial plants in various industries as well as in the municipal sector, dust emissions are produced during production processes. These emissions must be purified before they are released into the atmosphere. The dusts can be sticky, greasy, wet, dry or combustible and have different particle sizes. In general, they are between 0,1 and 1000 μm in size. Dust collection systems physically filter these dusts out of the exhaust air. WesselUmwelttechnik specialises in various methods of exhaust air cleaning, including industrial dust collector systems, to safely comply with legal requirements, e.g. the German TA Luft. In addition to dry filtering, the product range includes wet separators. This way, even humid and hot exhaust air as well as agglomerating dusts can be treated by the Wessel systems. The various exhaust air purification technologies allow the use of dust collecting systems in a wide variety of industries.

Operating principle The AGGLOControl scrubber does an excellent job separating the smallest particles and aerosols. This dust collector is suitable for removing fine particles down to grain sizes of less than 3 μm. This makes the AGGLO scrubber from WesselUmwelttechnik predestined for use in various industrial contexts. Exhaust gases and exhaust air of various types are filtered efficiently and, above all, costeffectively, and raw gas is freed from dust. Clean gas is released into the atmosphere that has been purified of over 95 % of particles from 1 μm in size. With the AGGLOControl scrubber, the higher the dust density, the more efficient the separation of the contaminants. The AGGLOControl scrubber from WesselUmwelttechnik scores with its compact and spacesaving design, which can be accommodated on any industrial site.
