  Axial Fan/Centrifugal Fan/Mixed Flow Fan &  Exhaust Blower


Computational design can effectively shorten the fan and blower development time from year or months reducing to weeks by use of virtual experiment technologies.  TADL developed its own tools to leverage this technology for specific design processes. Having unsatisfactory performance in your fan/blower and air moving system and want to improve it or want to design a new fan with tough performance requirements?  Check with us to see how we can help to define the problem and search for solutions with our unique competences.  Contact us by fan2@turbomoni.com

Fan  Performance Testing and Measurement


Fan and blower testing is often used to obtain the performance curves of a fan or an air system, or identify possible performance issue. It is also used to verify a modification to a existing design or qualify  simulation results from CFD simulations. The measured data can be static pressure, total pressure, flow rate, sound pressure level, rotational speed of rotor, shaft torque and thrust force etc.   Sound frequency spectrum analysis can also be performed to further determine and analyze frequency spectrum of the noises. 

Specifically for those need to measure small fan with low pressure and low shaft torque, we have special small measurement range test instrumentation and test techniques that can serve you better.

Energy Saving:  Opportunity Identification   and  Optimization

Many existing ventilation systems often have great potential to reduce  power consumption by increasing the efficiency of the system (not only the fan but the whole system). A higher energy efficiency system usually comes together with lower noise emission from flow separation and blade passing induced pressure variation. We are experienced in identify energy saving opportunities and find solutions to improve the system performance for operational cost effective.

   3D  Fan/Impeller Digital Model Generation                

For whatever purposes such as concept design, product design, model making, display presentation, rapid prototyping or academic research with FEA or CFD simulation, the most time consuming and difficult part of the job is to build 3D model of the blade/impeller due to its complication of shapes. We provide 3D fan blade and impeller generation service to help you get the job done so that you can focus on other parts of the work.

You just need to provide necessary data to define your fan blade/impeller. Such as number of blades, diameter of impeller, diameter of hub, airfoil type (more than 1500 airfoils available for your choosing from or you can use your own airfoil) of the blade, twist angle and chord between the tip and root of the blade. You can also define other features of the blade i.e. swept angle and lean angle (see the example images on the right side). The generated impeller 3D file will be sent to you by email within one working day. The generation of axial impeller can be a fan, a wind turbine or a propeller. The 3D file will be provided in STEP or IGES or other required formats.  Contact us by fan2@turbomoni.com 

Subtractive Rapid Prototype with 4 Axis CNC   


We build 3D models as rapid prototyping with 4 axis CNC milling machine. The material can be in wax, resins, chemical wood, acrylic, PVC, PC, ABS, wood or light metals such as  brass and aluminium. Click here for more information. The resolution of the prototype can be smaller down to 0.1mm. This method gives better finishing surface quality than most additive rapid prototype methods in  present market such as FDM,SLA or SLS. The most important point is that the prototype can be used to perform functional test because of using the same material of your final product.

TurboMoni  Testing and Remote Monitoring Kit               

Thanks to the application of MEMS technology based sensor, we are also able to provide very low  differential pressure measurement capability from 30psi, 15psi, 10psi, 5 psi,2500Pa, 1000Pa. Due to the introducing of the new  sensors for very low pressure range, the resolution can be down to 0.1Pa even 0.002Pa.  Which extends possible range of application, such as  clean room or indoor air flow monitoring etc. See our demo online for very small axial fan performance monitoring. 

TuboMoni provides  convenient tools for automated and continuous  monitoring, on site test and commissioning of fan conditions with meaningful scientific dataset for online or off line analysis. It helps users to get  crucial information about operating condition of the rotory system in order to maintain better operation conditions. With the kit, the measurement can be carried out automatically according to a predefined task schedule. The measured data will be automatically delivered to user's office or mobile phone through email or web server. You can also  acquire a new measurement by sending a command email to the system.

Wind  Energy Harvest Capacity  Evaluation for Wind  Turbine  Installation Site Selection               

For a wind turbine, higher power output coefficient Cp is the first thing to pursuit in selecting a machine. The site selection for installation is even more important to ensure the installed turbine will produce enough power as expected. A better installation site selection can help to shorten payback time. We provide wind energy evaluation through wind turbine simulation in cooperate with local wind data analysis to estimate the power capacity for your installation. It is a good practice to carry out such a feasibility study before move forward with investment.
