Hi-Tec Shut-Off Impulse Tool. The lightweight Yokota YLT series impulse wrenches with double chamber air motor achieve the required torque very quickly. The tools have a high number of impulses per second, and therefore very accurate torques can be realised, resulting in increased production speed. Design innovation and the application of new materials significantly reduce the weight and increase the service intervals. Yokota impulse wrenches are widely used for tightening jobs in the assembly industry, where accurate torque tolerances are necessary. Impulse tools are light, powerful, small and very importantly, have no kick-back. Evaluation of tightening processes in car assembly shows that tightening joints uses 10% of the total assembly time. Working with faster tools therefore can speed up assembly lines substantially. [...]

In many incineration and industrial plants of various sectors 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 resulting dusts can be sticky, wet, dry or combustible and have different particle sizes. Often industrial dusts are between 0.1 and 1000 μm in size and vary greatly in composition. They are also present in various concentrations and combinations with other pollutants. Compared to dry separators, wet scrubbers have the great advantage that fires or explosive mixtures cannot occur. Depending on the industry and area of application, such as in incineration plants, wet separators are indispensable.

Operating principle With this type of scrubber, coarser solid particles and fibres are filtered out of the exhaust air. The DLP (Dust Low Pressure) scrubber from WesselUmwelttechnik has a number of advantages. In addition to a long operating period, this wet dust collector system scores with a constant separation performance. Wessel uses only highquality materials to manufacture scrubbers. This results in a high chemical resistance. Thanks to automatic monitoring of the process parameters during operation, the highest possible operational reliability is guaranteed. The system reacts automatically to changes in the inlet conditions. All in all, the DLP wet scrubber is easily operable due to the practiceoptimised control system. The power consumption is comparatively low due to low pressure losses. Typical areas of application The DLP scrubber is used, among other things, in connection with the Wessel BIOCAT scrubber, which is used for biological exhaust air cleaning.

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.

Bio scrubbers are systems for the biological cleaning of exhaust air and exhaust gases and thus for the reduction of odours and polluting emissions. In this process, air polluted with a wide variety of pollutants is cleaned with the aid of a washing liquid which is loaded with microorganisms and biocatalysts (various enzymes) taken from nature. The bio scrubbers from WesselUmwelttechnik work almost without wastewater and are therefore very sustainable, regardless of the nature of the exhaust air. The basic requirement, however, is that the ingredients are watersoluble and bioavailable. WesselUmwelttechnik supplies turnkey plants like the Wessel BIOCATScrubbers in single and multistage construction.

The BIOCATDUOscrubber from WesselUmwelttechnik consists of two units. One unit is the already mentioned BIOCATscrubber. A second unit, the DLP (Dust Low Pressure) scrubber stage, is a cleaning stage for separating dust and fine fibres from the exhaust air. With the BIOCATDUOscrubbers from Wessel, gaseous pollutants as well as dust can be removed from the exhaust air at the same time. The BIOCATDUOscrubbers have two separate washing water circuits for this purpose. It is characterised by a compact design, as both units are housed in one column. COMMON USE CASES The BIOCATDUOscrubbers are used in the woodbased panels industry, for example. More precisely where MDF boards (medium density fibre) and moulded fibre parts are produced. Here the exhaust air contains fine wood fibres which have to be filtered out of the exhaust air. Furthermore, pollutants and odours must also be reduced.

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.

With heat recovery systems in industrial environments, the heat contained in the exhaust air is efficiently used to heat air or water. A very efficient use of this energy is the preheating of dryer supply air. The heat can be used continuously here. This warm exhaust air is also suitable for heating buildings. Depending on the local conditions, both airtoair heat exchangers and airtowater heat exchangers can be used for this purpose. The heated air, in turn, is fed into production and factory halls or other areas of the building. This type of supply air heating is particularly costefficient. Such recovery systems also have a positive effect in terms of environmental compatibility. Waste heat from industry that is harmful to the climate is no longer released into the environment but remains in the cycle of the production process or building heating. The systems are also suitable for cooling rooms when outside temperatures are hot, for example.

Adsorption plants are an efficient way of filtering VOC (volatile organic compounds) or other pollutants from exhaust air, flue and exhaust gases in industrial and municipal applications. In comparison to absorption processes, in which harmful substances are bound by the use of liquids, an adsorption plant concentrates the pollutants These are physically attached to an adsorbent such as zeolite or activated carbon. The adsorption process is efficient and costeffective, especially for low to medium pollutant concentrations in large volume flows. If necessary, concentrated solvents, for example, can be recovered and reused with the help of other technologies. Especially for exhaust air streams with low or medium concentrations of VOC and other harmful exhaust gases, the use of socalled VOC concentrators is of great advantage.

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.

Industrial air scrubbers are used to purify the exhaust air of pollutants, for example in the chemical or pharmaceutical industry. As soon as the exhaust air meets the legal requirements for clean gas values, it can be returned to the environment. Absorptive exhaust air purification by waste gas scrubbers is a frequently used technology. Gas scrubbers are suitable for removing pollutants, aerosols and dust from the exhaust air. Especially watersoluble exhaust air components are separated with high efficiency.

When it comes to filter material, there are a few points to consider. The filter material should have a large surface area. This ensures a good exchange rate between exhaust air and filter material and provides sufficient space for microorganisms to colonise. The filter material must be designed in such a way that it has a good water holding capacity. The colonised microorganisms are only viable in a moist environment. In general, different filter materials are used in one batch. The reason for this it ensures both a good stability of the filter bed and a larger surface. In addition, the added microorganisms must be sufficiently supplied with inorganic nutrients and trace elements, unless this is provided by the composition of the exhaust air. The temperature inside the biofilter system plays a decisive role as well. Temperatures between 5 °C and 40 °C are favourable for the microorganisms to work properly.

Biological exhaust air cleaning is used whenever exhaust air has to be cleaned from volatile organic compounds (VOCs) and odours. Biofilters play a major role in this process. The polluted exhaust air is passed through a filter medium where the VOCs and odours are separated. Normally, this medium is an organic carrier material where microorganisms are grown on. They convert the VOCs and odours into noncritical components by means of their metabolism. Especially regarding the removal of odorous substances, biofilters are a very efficient and comparatively inexpensive way of biofiltration with an efficiency of up to 99 %. BIOCATbiofilters have a high degree of efficiency in a wide range of applications, even for exhaust air components that are difficult to dissolve in water.

A bio scrubber combines physical scrubbers with a biological activation unit. In this process, air polluted with a wide variety of pollutants is cleaned with the aid of a washing liquid which is loaded with microorganisms and biocatalysts (various enzymes) taken from nature. The washing water absorbs the exhaust air and pollutants from the air. Subsequently, added microorganisms oxidise them. These microorganisms use the air pollutants as substrate and nutrient medium and convert them into naturally formed decomposition products such as CO2, water, and biomass. Here, the washing water is continuously regenerated and used in a closedcircuit water treatment system. TYPICAL APPLICATION AREAS These plants are primarily used for watersoluble ingredients of the exhaust air. The usual pollutants that are filtered from the exhaust air with the help of bio scrubbers include aldehydes such as formaldehyde, alcohols, ketones and other hydrocarbon compounds.

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.
