An important task carried out by TLT-Turbo is the conducting of aerodynamic model acceptance measurements and final acceptance tests in the presence of our customers. These tests demonstrate the aerodynamic performance of TLT-Turbo fans on a model test stand to meet the required fan characteristics.
Model tests are significantly cheaper and less complex than conducting tests on a full-size performance test stand (FSPT) such as the one that TLT-Turbo has set-up in Chengdu, China. TLT-Turbo has various model test stands at their facilities in Germany and is able to test different diameters of axial fans, centrifugal fans and full-size jet fans.
Due to the restrictions of the COVID-19 pandemic, it is not possible to host clients for witnessing tests at our R&D center in Zweibruecken. In an effort to continue providing excellent customer service and for current orders to move ahead, TLT-Turbo has found a solution – making acceptance tests available for customers to attend virtually!
Inspired by the global movement to move physical business processes such as meetings and inspections online, TLT-Turbo started looking for a software solution that would allow them to conduct virtual aerodynamic model acceptance tests.
The solution was found through software, which allows classic video conferences to be combined with a connection to virtual reality on smartphones, tablets, smart glasses, or a video screen. This makes it possible for participants in a teleconference meeting to see and experience everything as if they were nearby.
“Our team has run through the process and rehearsed internally to make sure that we are ready to fully cover every aspect of the testing and we are ready to offer this service to our clients to allow work and delivery of fans to continue,” says Dr. Sebastian Fleder, TLT-Turbo Product Manager for Aftermarket and Services. “This is a major advancement in the digitalization of our offering. In future, even as we move into a post-COVID world, this model will remain an alternative option to conventional model acceptance testing, trouble shooting, inspections and many other services for all customers as it saves them both time and money.”

Like the rest of the world, India is facing the challenges of the COVID-19 pandemic and the effects of their own national lockdown. Those living below the poverty line as well as day workers and laborers have been particularly hard hit by the nationwide lockdown that started on 23 March 2020.
India’s Prime Minister addressed the nation and requested support for those in need. To facilitate donations, a special PM Office bank account was set up for individuals and organizations who wished to play their part in helping the nation’s needy.
While working from home, the team at TLT-Turbo India started discussing the unthinkable challenges facing their less fortunate fellow citizens and decided that they wanted to step up. In a moving and overwhelmingly generous gesture, the entire team decided to donate one day’s salary to the cause. This response on an individual level inspired TLT-Turbo India management to match their donations as a company. Together they reached a total amount of just over 100 000 Rupees (1300 Euro) which was deposited into the PM Office account.
“We felt a responsibility towards this cause. We are grateful to be able to continue working from home when so many others cannot work at all. The TLT-Turbo India team working from home are in contact every day and through our discussions it came to light that this cause was something we were all thinking about. I know that this amount may not be as high as some donations by larger companies, but our intent and philosophy is always do what we can to care for others and I am so proud of my team for making this happen,” says Pankaj Sohoni, TLT-Turbo India Managing Director.
Global Managing Director, Rainer Redinger applauded TLT-Turbo India for their generosity and sense of responsibility toward their fellow citizens. “Civic duty and pride are near to our hearts at TLT-Turbo. This donation demonstrates this part of our corporate culture perfectly. Throughout the COVID-19 pandemic and the various lockdowns that have been put in place across the world, the TLT-Turbo Global Team continues to show not only astounding resilience and motivation but also empathy for those who have been hardest hit. I would like to personally thank TLT-Turbo India for leading by example and for showing the world how unified action and solidarity can make a difference.”

Global ventilation fans
and systems manufacturer, TLT-Turbo GmbH, has announced the redesign of its
Auxiliary and Booster fan range. Developed in close collaboration with clients,
the new designs address both efficiency and cost effectiveness, in a versatile
product range that meets the specific ventilation requirements of the mining
industry.
Development of the new fan range concept began in early
2015. Following a lengthy global market study to gain an understanding of the
market requirements, the range was defined in mid-2017, with fabrication of the
first units taking place shortly thereafter. “The development of the Auxiliary
and Booster fan range would not have been possible without the input of
clients. This ensured that we focused on key market driven requirements
including energy efficiency, noise reduction, cost effectiveness and turnaround
time,” says Michael Minges, Technical Director at TLT-Turbo Africa, who headed
up the fans’ designs.
“To sell these products we needed to ensure close customer
relationships and visibility. We are striving to change the industry’s mindset
on the use of such fans to ensure proper fan selection for the ventilation
required. In optimizing mine ventilation, efficient, high quality Auxiliary and
Booster fans can add as much value as surface fan installations.”
(Above) The new TLT-Turbo Auxiliary and Booster fan range addresses both efficiency and cost effectiveness
TLT-Turbo started commissioning of the first iterations of
the fan range towards the end of 2017 within the Sub-Saharan market through its
Africa office. From there, they based the development of the various fan sizes of
the new range on market interest. The fan designs and their performance
validation was completed at the end of July 2019. They aim to complete product
roll out, with all supporting documents and certification, by the end of
September 2019.
Minges explains that meeting identified market demands was
the main focus of the improved designs. “As energy efficiency is one of the
main drivers of industrial equipment usage, and minimum efficiency requirements
on certain equipment are often legislated, TLT-Turbo identified the need and
opportunity in the market for more efficient mining fans compared to what is
currently in use.”
The new designs include several innovative additions to
enhance performance in order to provide exceptional underground ventilation. The
fan range was developed using the latest in engineering flow technology which
allowed TLT-Turbo to improve the aerodynamics, and thus efficiency of the fans.
A unique stator design and aerodynamic fairings, all manufactured from wear
resistant composite materials, result in improved efficiencies and reduced
noise levels. The modularity of the fan casings allow for quick and easy
assembly with interchangeable ancillary fan parts. The motor mounting in coherence with a
machined impeller track ensures low and controllable blade tip clearances for
improved performance and efficiencies. Pad mount motors are used for all fan
sizes and help reduce vibration levels in the axial direction of the motor
significantly which leads to longer motor bearing life and lower maintenance
requirements.
(Above) The first orders for the new range were received at the end of 2017
Minges says that all possible measures are taken to ensure
the highest quality and best possible performance of every fan supplied by
TLT-Turbo. “All fans are ISO 5801 tested, unless the client agrees to type
testing on higher volume orders. We ensure the client quoted performance is met
before the fans leave the factory. Test certificates on both raw data and
calculated performance can be provided on request. Fan efficiency is determined
with the performance test and this quality check ensures we deliver on what we
promised the client. Clients are regularly invited to witness the performance
tests to sign off on acceptance. The fans also come with pressure ports that
can be hooked up to a calibrated handheld measuring device to measure
performance in-situ.”
In addition to performance and efficiency, ease of
maintenance was also a major consideration in developing the new Auxiliary and
Booster range. The modularity of the product design and the interchangeable standardized
parts allows for quick turnaround time on parts supply. “For example, we only
have two blade types for the full product range and generally only one motor
barrel per fan size accommodating various motor sizes and types. Standardization
on the product is the key to successfully managing maintenance and repair as it
allows ample supply of spares for companies certified to do the repair work.
The design track record has indicated a longer mean time between failure (MTBF)
than previous products,” Minges explains.
(Above) The new TLT-Turbo Auxiliary and Booster fan range is available to clients worldwide
The fan range is being rolled out in phases. The preliminary
testing at sites located in Sub-Saharan Africa has been launched successfully.
The next phase is globalization as the new range will be rolled out in the USA,
Canada, Europe, Russia and Australia. Following this, product supply and
support will be extended to TLT-Turbo offices in South America and India. In
the interim though, Minges says that these fans can be supplied to clients
worldwide from TLT-Turbo Africa.
TLT-Turbo Africa has received a number of orders for these
fans since the end of 2017. These orders include South African clients seeking
a solution for deepening a gold mine, and for Kamoa Copper in the DRC as an
exclusive supplier. “The feedback that we have received thus far has been that
the fans are meeting our and client expectations. I am proud to say that one
EPC consultant used the phrase ‘super fan’ to describe the new range and
indicated that he has not heard a fan of this size so quiet before,” says
Minges commenting on the reception of the new range.
“The Auxiliary and Booster fan range was developed to
enhance TLT-Turbo’s mining ventilation product portfolio. The product is based
on historic innovative designs by the TLT-Turbo Africa R&D team. Continual
product development and keeping up to date with the latest technologies is
ingrained within the engineering teams of TLT-Turbo. Ensuring that innovations
are market and client driven with the end result being a benefit to the
industry, puts us in the forefront of advancement in ventilation solutions,”
Minges concludes.
TLT-Turbo GmbH builds
radial and axial flow fans for virtually any application. First-rate
engineering, tradition and progress in air handling technology and a worldwide support
network have been the cornerstones of their excellent global renown as a fan
and systems manufacturer for more than 140 years. TLT-Turbo GmbH fans and the
associated system components are deployed successfully all over the globe. To
date over 10,000 fans have already been installed. Their subsidiaries, branches
and agencies span the globe including TLT-Turbo offices in Germany, China,
Austria, Russia, South Korea, USA, Chile, Hungary, Australia, India and South
Africa.
Global ventilation fans
and systems manufacturer, TLT-Turbo GmbH, has spent the past five years
investing in and equipping its on-site test lab. The test lab now provides
streamlined processes for research, advancing product quality and expanded
capabilities for material testing. With a focus on particle impact wear
testing, the test lab is driving innovation forward at TLT-Turbo as the results
help improve product reliability, quality and performance in their final
operating environment.
Patrick Baumgärtner a Research and Development Engineer – and
expert in wear and corrosion protection – at TLT-Turbo, has played an
instrumental role in building up the test lab – located at the TLT-Turbo
Development Centre in Zweibruecken, Germany – to its current capabilities.
Together with Sabine Groh, Industrial Fans Product Manager at TLT-Turbo, they have
been spearheading the current research.
Currently, the core field of research at the test lab is the
testing of new wear-resistant materials and coatings for fan components.
Baumgärtner says that the testing takes place in the lab’s solid particle impact
wear test bench. There, various types of dust or abrasive particles are blasted
onto the test material, varying the angle and speed of the blasting to observe
the resulting wear. “We also carry out caking tests in which we select, for
example, anti-adhesive layers for our fans, in order to find suitable solutions
for customer applications. A further main focus is the analysis of process
residues that can have an abrasive or corrosive effect. Here the composition,
size distributions, pH value and conductivity in the eluate are determined,”
Baumgärtner explains.
(Above) Part of the materials testing laboratory in Zweibrücken
TLT-Turbo’s approach is to continuously test materials,
coatings and components in order to produce fan components that are designed
for performance excellence in any operating environment – no matter how
abrasive. This testing is applied to current and new products in development
but also to samples that are brought in from client sites in order to establish
the wear patterns caused by their specific environment. In this way, TLT-Turbo
is able to provide each client with a customized solution that will last longer
and require less maintenance.
The test lab now offers facilities for metallography, a
stereomicroscope, a pycnometer for determining the density of materials and
coatings, and an automated solid particle impact wear test bench. “The
capabilities of the test lab open a lot of doors for advanced research that
will make a positive contribution to the engineering community at large as
well,” says Baumgärtner. “Under my supervision, studies and thesis research
takes place in the laboratory in cooperation with local colleges and
universities. For me, this is the basis for successfully researching and
developing new solutions in our field.”
According to Groh, the test lab has almost endless
possibilities for the improvement of product delivery to clients. “Our
customers are often operating TLT-Turbo fans in abrasive and/or corrosive
environments. To develop suitable solutions that match the wear resistance
against particle impact we use our automated solid particle impact test bench.
Compressed air accelerates a defined mass flow of abrasive particles to
velocities up to 300 m/s and propels them onto a piece of sample material. This
leads to material loss and wear that we can examine. It is even possible to use original dust from
a customer’s plant to evaluate the most suitable solution for them. By varying
the impact angle we can observe system characteristic wear curves. With this
knowledge we can provide customized solutions for many processes.”
(Above) Exchangeable impeller blade exposed to massive wear
These customized solutions can be best illustrated in the
selection of coatings. This, says Groh, has an immensely positive impact for
TLT-Turbo clients. “If we were to propose a new coating for a customer, the
wear rate of the coating would be determined first. That is the main
scientific-based decision criteria for wear resistant coatings. If the coating
has a superior wear rate compared to other coatings or at least a wear rate
that is on par with other coatings and another beneficial quality such as
anti-stick effect, corrosive resistance or a cost advantage it will be
implemented into TLT´s coating portfolio.”
Groh says that they have also conducted tests that have led
to the development of completely new proprietary coatings. “During the manufacturing
process, coatings were tested to see the influence of welding heat on coating
qualities – such as the development of cracks – to ascertain how to avoid
damage caused by heat or weld splashes. We conducted research and testing on
combining welded coatings and thin layer coating into a Hybrid Coating which
can dramatically increase the operational lifespan of TLT-Turbo fans at their
clients’ plants.”
This is one of numerous examples of how TLT-Turbo’s testing
capability can positively impact ventilation systems across all applications.
“Due to the broad database of wear tests on various materials and coatings, we
are able to offer tailor-made wear protection solutions for various processes
of our customers,” Baumgärtner acknowledges.
(Above) Blasting nozzle and sample holder of test bench
Groh agrees, adding that the wide variety of chemical
compositions and coating conditions such as acceleration of coating powder and
heat development make it extremely difficult to objectively find the best coating
by carrying out testing at a customer plant. “The process of reaching just
initial findings in these conditions is very time consuming. In addition to
this, there is a broad variety of conditions to contend with at different
customer plants that hinder an accurate comparison of different coatings at
different plants. If you test different coatings on one machine you might get a
rough estimation what coating is superior, however different wear rates of
coating cause imbalances in the impeller and vibrations at the fan.”
She elaborates by explaining that finding a precise
comparative measurement on different coatings is impossible without being able
to analyse how the wear rate changes at different angles. “At the test lab we
can control the conditions to find precisely what we are looking for in a
shorter timeframe. Additionally we are able to replicate the fan’s operating
environment. We can run tests using dust collected from the client site while
simulating particle speeds that match the client’s environment to precisely
simulate wear rates.”
In the laboratory environment, the TLT-Turbo team is also
able to determine additional coating properties as they have the capability to
run additional experiments, e.g. corrosive resistance, anti-stick effect,
robustness, heat resistance, suitable application methods, and combination
possibilities like hybrid coatings.
The test lab has afforded TLT-Turbo engineers a deeper
understanding of the mechanisms behind wear and the effects of specialized
solutions. This has led to new approaches in product advancement and
development that are grounded in providing solutions that meet market
requirements.
“The analysis of residues from plants has a great influence
on product development as we are making more informed decisions when choosing
materials for corrosive and abrasive environments,” says Baumgärtner.
This has also had an impact on TLT-Turbo’s aftermarket
service offering. The test lab, has allowed for new customer services can be
generated, such as the performance of specific tests for customers. “The development
of new solutions for specific customer problems is now much faster and more
accurate. Also the suitability of low cost approaches or solutions that allow
for wear induced damages to be repaired on-site integrate effortlessly into TLT-Turbo’s
existing solutions,” Groh concludes.
The test lab enables TLT to continuously improve their
solution portfolio for different customer problems with a focus on wear. The
combination of understanding the client’s exact requirements and challenges and
having a tool that allows engineers to find the best solutions from a
scientific basis are a key factor for success in the market and play an
important role for TLT-Turbo’s on-going product development and quality client
delivery.

TLT-Turbo GmbH, a global ventilation fans and systems manufacturer, has launched a new range of mechanical vapor recompression fans, with ceramic hybrid bearings that provide an exceptionally long operational lifespan. Integrating the latest ventilation technologies, this fan offers numerous advantages regarding performance efficiency, minimal maintenance and high reliability.
The TLT-Turbo fan for mechanical vapor recompression (MVR) has been in development since 2012 since the first case studies were carried out. Following intensive discussions with clients, TLT-Turbo established that a need existed for low maintenance MVR fans. This was followed by four years of intensive research, product testing and consultations with clients. The first MVR fans were rolled out in 2016 while continual product improvement has remained a focus area for TLT-Turbo.
“MVR fans have been available on the market for some time but instead of just following the trend, TLT-Turbo took time to ensure that we came to the market with a completely new, state of the art MVR solution,” says Mario Schmidt, Head of TLT-Turbo’s Vapor Fans business segment. “And we continue to have on-going discussions and feedback exchanges with our clients worldwide in order to continuously adapt and improve our MVR offering to their requirements.”
According to Schmidt, the features of TLT-Turbo’s MVR fan, such as the lower maintenance requirements and the introduction of hybrid ceramic bearings, underscores their commitment to developing products in close alignment to their clients and their needs, and also speaks to TLT-Turbo’s key objective for continual innovation.
(Above) The new TLT-Turbo fan for Mechanical Vapor Recompression
The implementation of hybrid ceramic bearings is a key differentiator of the TLT-Turbo MVR fan. “Our clients are amazed by the possibility of a hybrid bearing operating at high speed without circulating oil. Conventional roller bearings do not provide the required support for operating the fan in a broad operational speed range without running into harmful resonance frequencies (under critical operation). Thanks to continuous enhancement in recent years, especially through the use of ceramic materials, more effective roller bearings are available today. The use of hybrid bearings with steel rings combined with ceramic rollers has been established in many industrial applications and in the case of the TLT-Turbo MVR fan, hybrid ceramic bearings mean significantly lower maintenance requirements and better operational performance,” Schmidt explains.
The hybrid ceramic bearings used in TLT-Turbo MVR fans are life time greased and can be operated for up to 10 years without requiring maintenance. To enhance this benefit for clients, TLT-Turbo introduced an additional device to the fan’s design that allows for the bearing to be re-greased from the outside in order to further simplify maintenance and to increase the fans’ service life.
High motor speeds, a wide range of optimized impellers and the allowance for high temperature and pressure increases complement the lifetime greased hybrid ceramic bearings to ensure that clients benefit from the enhanced performance and efficiency that they have come to expect from TLT-Turbo products. These factors allow for operation of the fan below critical speed which ensures both reliability and safe operation.
(Above) A high efficiency will be achieved with an optimized impeller design
“Reliability and safety are key concerns for our clients and TLT-Turbo has addressed this in the MVR fan by using high quality components. Thanks to the use of the hybrid bearings, no oil supply or oil pump is necessary which means that no oil can contaminate the product. In addition to this, the fan also features temperature and vibration monitoring and remote monitoring of the bearing is possible as well. Our entire manufacturing process is carried out according to all major quality standards, including DIN ISO 9001,” says Schmidt.
The TLT-Turbo MVR fan is suited to numerous applications in the chemical, pharmaceutical, waste water treatment, and the organic natural product production industries as well as in the food and beverage process and manufacturing sectors. “Since 2018, we have received 35 orders for MVR fans across the globe with one installation completed. Thus far, the feedback from clients has been very positive. We have received reports that the bearing temperature is considerable lower than that of other comparable MVR fans and that our fan runs with less vibration than other MVR fans,” Schmidt affirms.
“Overall, TLT-Turbo’s objective was to offer our clients a mechanical vapor recompression solution that would outperform what was currently available on the market. We have delivered a fan that requires less maintenance while providing high efficiency and reliability. This is exactly what clients would expect from TLT-Turbo as a world class fan manufacturer and global service organization.”
