LTG High Performance Tangential Fans
Even airflow over large areasTemperature range from -40 °C to +800 °C (-40 °F to +1500 °F)
Many production processes require an extended linear and absolutely even distribution of air or other gases over a certain area.
The special design of LTG High Performance Tangential Fans provides the optimum solution for these requirements.
The robust design and the use of high quality materials assure a long life expectancy. The way these fans work, allowing even air distribution without additional baffles and vanes, and the spacesaving design, make the use of tangential fans very economic.
Flow principle:
In a tangential fan, the air is drawn in over the entire length of the fan impeller. Inside the impeller, the airflow is diverted and accelerated by the vortex created by the rotation of the impeller.
The airstream then exits over the entire length of the impeller on the discharge side. The vortex separates the intake and discharge side of the fan at the narrowest point between the impeller and the vortex builder. Together with the fan scroll, the vortex directs the airflow. This results in an almost uniform laminar airflow over the entire outlet width of the fan.
LTG High Performance Tangential Fans To achieve better product quality and to improve the production process
airflow 90°
airflow 180°
Axial
• Fans perform well in any mounting position. Drive can be mounted on right or left hand side.
• Quiet operation due to optimised impeller and housing design.
• Long life expectancy due to robust design and location of bearings outside the hot air zone.
• Explosion-proof models according to ATEX available.
Advantages:
• Uniform, extended airflow over large areas.
• Space-saving installation due to 90° and 180° airflow pattern.
• Fan length can be matched exactly to machine width.
• Airflow conditions remain the same even for wider machines (simplified design and drafting in case of modular systems).
Choose LTG High Performance Tangential Fans
LTG High Performance Tangential Fans: easy to incorporate into your design
In various industries, tangential fans provide effective cooling, heating or drying. This assures a flawless function and quality improvement of machinery and equipment. The specific design of the tangential fan saves space and provides the designer with a lot of freedom during the design process.
Complicated additional air guidance systems, such as ducts or guide vanes to optimise the air or temperature distribution, are not required. The whole assembly can be produced smaller, more compact, saving a lot of space.
LTG Aktiengesellschaft offers fans for all airflow patterns:the best prerequisite for objective technical advice.

Our services• We analyse your existing systems, machinery and processes.
• Together with you, we define your requirements, taking all the relevant parameters into account.
• To find solutions, we use our broad know-how plus numerical and experimental flow analysis.
• The result: solutions that are tailored according to your needs. For example, we optimise the airflow in your process and maximise your energy efficiency.
Experimental flow investigations and optimisationThe visualisation of airflow on site or in an LTG flow laboratory, at reduced or original scale, provides certainty. Process parameters like air speed, pressure and temperature can be optimised. We apply the results of CFD simulations to the given situation and verify them with the product or process.
Acoustic optimisationMeasurements of your product’s acoustic power level in LTG’s reverberant echo chamber are part of our engineering services. Here we analyse sound spectra and optimise your product’s acoustic properties in a systematic manner. Additionally, we measure sound pressure levels on site at your workstations and systems.
On-site measurementsOur specialists determine the parameters of the existing system on site. Based on these parameters, together with you, we define your requirements and suggest ways to solve your particular problem. This information is used for numerical flow simulations and experimental verification.
Computational Fluid Dynamics (CFD)Computational fluid dynamics permits the calculation and visu-alisation of airflow for existing or planned systems and processes. By varying different parameters we develop reliable, innovative flow concepts and significantly shorten the development time.
