Improved even further: electronics, handling and performance

Concomitant with the launch of the new INSPIRE control electronics, the TBH GmbH has also optimised the mobile filter and extraction systems of its FP200 series. In this manner, improvements were achieved in terms of transport and handling while the performance was improved even further, too.

These systems equipped with cleanable filter cartridges are particularly suitable for applications demanding the extraction of high amounts of dust. This includes, for instance, laser processing – in part also in combination with precoating – or mechanical processing such as grinding, deburring, milling, drilling or cutting as well as decanting, packaging, supplying or forwarding processes. Thanks to the use of special high-performance blowers or rather turbines, the systems feature a high effective air flow rate allowing their use as a decentralised extraction system for multiple workstations. The colour display of the new INSPIRE control electronics allows intuitive handling without complicated menu navigation. At first glance, the user is provided with a quick overview of any relevant information concerning the system status. The extraction performance is controlled by means of plus and minus buttons on the control panel and the filter-cartridge cleaning can be started by the push of a button. In addition, the interface available now also includes an error memory and a special programming access easing the support communication and the adjustment of the system to the customer’s specific requirements right on site.

Moreover, the complete system structure has been further optimised as well. The dust collector has been enlarged by 50 % thus reducing the maintenance efforts. The motor module was modified too. In case servicing becomes necessary, it can now be performed much easier. Considerably reducing the design height, the system transport is eased significantly thus cutting any related costs.

Thanks to the use of a new blower providing an increased vacuum level, the system performance was also improved. Despite increased performance, the energy-saving and low-noise characteristics of the system are preserved. In terms of noise, the levels reached fall below 68 db (A) thus allowing the application of the system in workshops and production facilities.

Laser processing: efficient extraction of pollutant particles

Laser processing causes hazardous and health-damaging emissions. Appropriate and powerful extraction and filter systems are thus required in order to meet the statutory provisions regarding the maximum pollutant concentration at the workstation. Thanks to its particularly large prefilter and the new INSPIRE control electronics, the TFS 1000 extraction and filter system by the TBH GmbH meets these requirements in a highly efficient manner.

By developing the TFS 1000 filter and extraction system, TBH managed to successfully close the gap between small and large system series for laser processing. The system is designed for laser processing applications with 30 to 150 W CO2 lasers or 10 to 50 W solid-state lasers with a working surface of up to 1,500 x 1,000 mm. It even copes with applications demanding high volumes of air such as, for instance, the simultaneous extraction at multiple workstations. The large filter surface and the concomitantly long system service life are particularly suitable for applications having to deal with medium or high amounts of dust.

During operation, the process air is extracted by means of an intake socket before passing several filter stages, a high-performance blower and the silenced exhaust vent recirculating it to the workstation. The SafeLine prefilter developed specifically for this system serves as first filter stage. It separates approximately 80% of all particles. Optimum inflow across the whole filter surface reduces losses within the filter. Heavy particles settle at the bottom of the filter thus not clogging the filter surface. The SafeLine filter is located within a closed filter housing which can easily be closed during the filter replacement thus preventing the user from coming in contact with the filtered matters. The next filter stage consists of an H14 particle filter complying with DIN EN 1822 and separating even smallest particles. The subsequent activated-carbon/BAC filter separates gaseous substances and collects odours. All filter stages can be replaced independently from each other and without any tools thus significantly easing the handling of the system. TBH will realize and launch additional systems based on this system concept in order to complement the output range both at the lower and at the higher ends.

The TFS 1000 filter and extraction system is equipped with the new INSPIRE control electronics allowing, for instance, separate filter monitoring of the SafeLine filter and the particle filter thus easing the maintenance planning and optimising the maintenance costs. The integrated colour display allows intuitive operation without complicated menu navigation and provides a quick overview of any important information concerning the system status: filter saturation, system status, performance settings / operating-hours meter, prefilter status, main-filter status, display and notification of malfunctions, etc. The integrated interface includes an error memory and a special programming access. On the one hand, this improves the coordination between the customer and the TBH service; on the other hand, it facilitates the adjustment of the system to the customer’s specific requirements directly on site.

New prefilter: focusing on customer benefits

Constant further development and optimisation of our filter and extraction systems is a major concern for TBH GmbH. As is the case with the new INSPIRE control electronics all systems will in future be equipped with, we thus focus on both technical development and on our customers’ operating/maintenance costs. In order to reduce the operating costs and for improved system availability, TBH now introduces a new prefilter for its range of systems: the Z-LinepanelPLUS filter.

When optimising the filter service life of filter and extraction systems, special attention is paid to the prefilter for being the most important system component. Thanks to improved production processes, the filter surface of the well-known Z-Linepanel filters can now be doubled. Depending on the individual case of application, the filter service life can thus be increased by up to 100% – without increasing the retail prices.

The advantages of Z-LinepanelPLUS filters are perfectly clear. Besides an increase in service life by up to 100%, the maintenance and operating costs are reduced accordingly. At the same time, the system availability is increased as well. In order to be able to benefit from the advantages of the new Z-LinepanelPLUS filter despite using an existing TBH system, it has been adapted to the modular system design. Existing systems can thus easily be upgraded by retrofitting.

The new centrepiece of TBH filter and extraction systems

The TBH GmbH, leading manufacturer of filter and extraction systems, presents its completely new INSPIRE control electronics. As a result of intense development work, the new centrepiece of TBH filter and extractions systems is now ready for operation from December 2015 onwards. In future, all of the TBH systems will be equipped with the new control electronics. That pays off as the new control board combines both easy operation and an appealing design.

During the development of the control board, the main focus was on creating a design as lean and manageable as possible thus easing the operation for the customer. A prerequisite therefore was a layout providing an immediate overview of the system’s actual state. This allows the operator to see possible system faults already from afar thanks to the use of blinking colour icons. The regulation of the extraction performance is now done by means of plus and minus buttons on the control panel. Furthermore, the colour display now also shows the hours of operation. In addition, the new interface is now also equipped with a notification memory. In case a problem occurs, it can be read out thus easing the troubleshooting.

In addition to the functions of saturation-filter systems, filter-cartridge systems now also feature the possibility to start the filter-cartridge cleaning by the simple push of a button. Depending on the customers’ preferences, the cleaning can either be started in accordance with a set interval or once a certain differential pressure has been reached. If required, automatic cleaning can also be started once the system has been shut down. This is achieved by means of the parameterization access. In combination with the TBH software, it allows adjusting each and every parameter to the customers’ requirements.

For TBH, the new INSPIRE control electronics resembles a complete redesign. Thanks to the lack of protruding switches and control knobs, cleaning the display has become much easier, too. Moreover, the new display is splash-proof, allows intuitive operation and thus prevents any complicated menu navigation.

TBH GmbH donates an extraction system to Makerspace Leipzig

Makerspace Leipzig – the interactive workshop open to anyone who likes tinkering, developing and advancing his/her own projects. The members of this society are between 14 and 69 years old and include both students preparing and working out their own startup as well as former executives from the industrial and research sectors supporting the members of the society and interested parties with their extensive knowledge.

In this manner, the society’s laboratory is used for work on exciting laser projects, for instance. Of course, the success of these projects also depends on both the technical and the peripheral equipment. The TBH GmbH from Straubenhardt (Germany) thus supports the society and provides a type BF 100 filter system for laser applications. Its individual filter steps for different particle sizes reliably remove any pollutants arising during laser processing. Afterwards, the cleaned air can either be recirculated to the work area or discharged into the open air outside the laboratory. With this donation, the TBH GmbH does not only ensure clean air at the laser laboratory, but it also assumes part of its social responsibility.

Mobile extraction and filter systems for laser applications

TBH GmbH presents the new generation of the GL Desk extraction and filter systems for use in laser applications. The system is the result of thorough development. It was specifically designed for its application as base unit for small laser markers. It combines the extraction and filter function with the advantages of a work bench. Just like the TFS 1000 extraction and filter system, which has recently been presented, the GL Desk series is now also equipped with the new INSPIRE control electronics.

Several parts of the system were analysed and improved at the new generation of the GL Desk series. In future, the system will consequently be equipped with an even bigger prefilter increasing the service life of the system by up to 50%. The optimised airflow inside the system furthermore allows an improved inflow into the filter thus easing the system cleaning.

In addition to the individual filter levels of the GL Desk series, the whole system concept has also been reviewed and the modular concept, which has proven itself in other TBH systems, was now implemented for the new system as well. In case servicing is required, the turbine module can now be sent independently from the whole system thus significantly reducing the customers’ efforts and expenditures.

The significant cost reduction for the extraction and filter system is yet another benefit of the redesign. It was achieved by optimising the production and by the new design of the body. As a consequence, the retail price of the new GL 30 was reduced by more than 20 % in comparison to the previous model of the system.

Despite reduced costs, the new generation of the GL Desk series also uses the INSPIRE electronic control system. The new colour display allows intuitive handling without complicated menu navigation and provides a quick overview of any important information regarding the system status. In addition to the known features, the new interface now also includes an error memory and a special programming access. On the one hand, this improves the support communication between customer and retailer or manufacturer and, on the other hand, it facilitates the adjustment of the system to the customer’s specific requirements directly on site.

Another main aspect during the development was the preservation of the following attributes also for the new system generation: energy-efficient, powerful, quiet. Using a new blower, the system’s energy-saving and low-noise characteristics are preserved despite the increased vacuum level. With a maximum noise level of 53 dB(A), the system can even be used in noise-sensitive areas.

TBH DT 100/150 downdraft table

The compact DT 100/150 downdraft table by TBH GmbH was developed as a combination of a standing workstation with an integrated extraction system. It is mainly used for the extraction of dusts and gases arising at certain working processes – e.g. when decanting or filling solid or liquid substances within a protective enclosure. It is particularly suitable for applications in workshops, laboratories and at the production of electronic components. Using DT 100/150, gluing and paint works with liquids containing solvents can be performed safely and in compliance with the given workplace requirements. The DT 150 version of the downdraft table was developed in accordance with ATEX guidelines and is suitable for the zones 22 (dust) and 2 (gas) thus complying with ATEX category EX II 3GD.

Besides its compact size with dimensions of 1 800 mm x 800 mm x 680 mm (H x W x D), the downdraft table features additional specific product characteristics. Using the integrated height adjustment, the working height can be adjusted infinitely between 850 and 950 mm. The protective screen and the possibility to adjust its height in steps of 50 mm allow a further optimisation of the application-oriented workstation configuration. For even further improvement of the user friendliness, the system is also available with a factory-fitted foot switch as optional accessory. A differential pressure indicator located on the front of the system allows monitoring the saturation filters. As most of the TBH extraction systems, the downdraft table also features a multi-level design. It comes with a prefilter (F5) as part of its standard equipment. Depending on the specific application purpose, the system can additionally be equipped with a particle/HEPA filter (H13) extracting finest dust particles and with a gas filter (activated carbon/BAC).

Mobile extraction and filtration systems for laser applications

During the LASER World of PHOTONICS taking place in Munich from May 22 to 25, 2015, TBH GmbH presents a new generation of extraction and filtrations systems for laser marking and engraving applications: the new TFS 1000.

The system is the result of intensive development work. It is used for 30 to 150 W CO2 lasers or 10 to 50 W solid-state lasers (fibre lasers and crystal lasers) with a working surface of up to 1,500 x 1,000 mm. Within the TBH product range, TFS 1000 is the first system equipped with the new electronic control system INSPIRE.

At the development of the TFS 1000, the main focus was on the prefilter as most important component of the system. Separating about 80% of the particles it is, at the same time, the most stressed component. Optimum filter inflow and a large filter surface concomitant with a small overall size thus are the main requirements for a reliable operation of the system. Furthermore, the prefilter bears the highest risk for the operator to come in contact with harmful filtered matters. These demands placed on an optimum prefilter led to the development of the new SafeLine filters. At these filters, air is led directly into the filter preventing the formation of deposits. The complementary gravity separation of heavy particles does not affect the filter surface. Two separate filter packs enable an optimum inflow into the filter medium. Thanks to this concept, the air speed within the filter is reduced significantly thus considerably expanding the service life of the filter. Low-contamination filter disposal and the replacement of the filter can be carried out easily and without any tools by simply closing the filter.

In order to meet the constantly growing safety requirements of our customers, particularly in the area of laser welding, the TFS 1000 is equipped with an H14 particle filter (meeting the DIN EN 1822 standard). This filter even facilitates the separation of ultra-fine particles and enables the recirculation of the cleaned air to the work area. For easy handling of the filter, it is braced directly onto the prefilter by means of a new tensioning system inside the extraction and filtration system. In this manner, service on the system is optimized as well.

The increase in service life of the activated carbon / BAC (biological activated carbon) was another major aspect during the development. It is the stage of the filter separating gaseous substances. For a further increase in lifetime, the entire airflow inside the filter was modified as well thus optimizing both the flow rate and the contact time of air and granulate.

As is the case with all of the TBH activated-carbon/BAC filters, TFS 1000 also uses two different filter materials for the absorption of gaseous substances. While activated carbon supports the physical absorption process, BAC granulate is used for chemical absorption. Neutralisation of specific gaseous substances is achieved through chemical binding with the reaction substance applied to the carrier material. Since physical and chemical adsorption processes are complementary, an extremely wide range of gases and odours can be collected.

In addition to comprehensive innovations in the areas of filter structure and system handling, the TFS 1000 is launched with the new INSPIRE control electronics. Its integrated colour display enables intuitive handling without complicated menu navigation and provides a quick overview about important information regarding the system status. Separate monitoring of prefilter and particle filter contributes to optimized service on the system and reduced costs for replacement filters. In addition to the known features, the new interface now also includes an error memory and a special programming access. On the one hand, this improves the support communication with the retailer/manufacturer and, on the other hand, it facilitates the adjustment of the system to the customer’s specific requirements directly on site.

Mobile extraction and filtration systems for laboratories and production

At the most important trade meeting of the sector of pharmaceutical and chemical technologies, the ACHEMA taking place in Frankfurt/Main between 15th and 19th June 2015, the TBH GmbH located in Straubenhardt will once again show a selection of its extraction and filtration systems as well as interesting enhancements and complements to the product range.

For the extraction of unwanted and dangerous emissions, TBH offers compact and mobile extraction and filtration systems geared to the specific requirements and needs of processes in laboratories and production plants. The systems with their modular design prove themselves in different areas of application. Emerging harmful gases are absorbed by activated-carbon filters while dusts are extracted reliably. Very compact extraction and filtration systems such as the BF5 and BF10 can be used in a space-saving manner. They feature both a reliable performance and the desired operational comfort.

ATEX work areas demand special requirements regarding safety and occupational-safety technology. TBH meets these requirements with its downdraft table DT 150. It combines an ATEX-compliant extraction unit with a standing workstation for filling and decanting tasks as well as for dosing and weighing processes. DT 150 can be equipped with the – individual or combined – filter cartridges required in each case.

Even the extremely high quality standards for clean rooms and sensitive production areas are met by TBH. Therefore, the CR series was subject to consistent further development focusing on customer benefits and process safety. Certainly, the most critical aspect of such a system is the filter replacement inside the clean room. This aspect was now “alleviated” by the use of a transfer-liner system. In addition, the future CR series will be equipped with new, advantageously priced filter blocks.

For customers purchasing a CR extraction system, TBH also offers the installation qualification (IQ) and the operational qualification (OQ). In other words, if desired by the customer, he does not only receive instruction, assembly and final acceptance of his CR filtration system (IQ), but also documented function tests and classification measurements related to the intended use of the device (OQ).

The TBH trade-show presentation is completed by the proven and practice-approved extraction and filtration systems of the LN and GL series. Useful and practice-oriented accessories such as extraction arms, table cabinets and collection elements for these systems will be shown as well.

Mobile Extraction and Filtration Systems

For many years, Europe has been a pioneering trendsetter in the areas of industrial safety and health protection. It is thus no surprise, our customers’ requirements concerning extraction and filter technology, particularly for laser and welding applications, increase steadily.

In order to meet our customers’ safety requirements even better, TBH has complemented its product range by different extraction and filter systems specifically tested by the German Institut für Arbeitsschutz (IFA) [Institute for Occupational Safety and Health] in accordance with DIN ISO 15012-1 (2013). They meet the requirements of the welding-fumes discharge class “W3” as described at the mentioned standard. This makes them particularly suitable for the separation of particles arising when welding steels with alloy percentages exceeding 30 % – e.g. nickel and chrome alloys.

These TBH systems thus meet the required conditions described in TRGS (Technical Rules for Hazardous Substances) 528, paragraph 4.5: “air return”. That is, safe returning of air to workplaces used for welding or similar tasks emitting carcinogenic, mutagenic or reprotoxic (CMR) substances of the categories 1 and 2.

As an expert on the area of extraction and filter systems, we thus contribute to human and environmental safety as well as to the safety of machinery. In order to ease the internal approval checks at your company, we would be pleased to provide your company’s safety officers with the corresponding verifications and certificates regarding our systems. In addition, all of our systems are marked with the “W3” label described in TRGS 528.
