Industrial Fan Software

Nowadays, ventilation engineering cannot be effective if it does not resort to specific analytical calculation programs.

In the real-world, it is very common to find oversized fans operating under conditions of poor performance, resulting in excessive and unnecessary consumption of electrical energy.

Fan Types

Designed to meet the needs of the air moving industry, including HVAC, our industrial fan software is a dynamic tool that accurately performs sizing of centrifugal fans and blowers, and axial fans.

Centrifugal Fans

  • Airfoil
  • Backward Curved
  • Backward Inclined
  • Radial Blade
  • Radial Tip
  • Forward Curved
  • Pressure Blower

Axial Fans

  • Propeller
  • Tubeaxial
  • Vaneaxial
  • Variable Pitch
  • Mixed Flow

Standards

Fan Standards

For the sizing of fans, the programming logic is developed according to engineering concepts homologated by international standards and institutions, such as:

  • AMCA - Air Movement and Control Association International, Inc.
  • ANSI - American National Standards Institute
  • ASHRAE - American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc.

Sizing of the Fan

The correlation functions used to calculate dimensional and physical parameters of each new fan have their origin in the classical theories of fluid mechanics, becoming known as the Fan Laws or Affinity Laws, while the noise predictions are based on acoustic principles and guidelines established by professional organizations.

For better accuracy, the software can also perform calculations and analysis improved by considering Reynolds number, Mach number, viscosity and compressibility of the fluid.

Calculations and Analysis

Centrifugal Fan CAD

In a highly organized, flexible and friendly environment, the user establishes the design requirements and the software performs all calculations and analysis necessary for sizing of the fan:

  1. The user supplies the design parameters.
    • Fluid Type
    • Fluid Temperature
    • Fluid Specific Gravity (Density)
    • Altitude / Elevation
    • Required Flow Rate
    • Required Pressure
    • Inlet Pressure
  2. The software adjusts the parameters in accordance with the fluid properties.
  3. The software simulates the use of each type and size of fan.
  4. The software calculates diameter and width of the fan impeller.
  5. The software calculates the operating rotational speed.
  6. The software analyzes the performance and suggests the most suitable fans.
  7. The software generates a selection list with sorting and filtering capabilities.
  8. The software plots performance curves of the selected fan, such as the following:
    • Flow Rate × Static Pressure
    • Flow Rate × Total Pressure
    • Flow Rate × Power - Brake Horsepower
    • Flow Rate × Static Efficiency
    • Flow Rate × Total Efficiency
    • Flow Rate × Sound Pressure Level - Noise
    • Flow Rate × Sound Power Level - Noise

Multiple Variable Graphs

Frequency Inverter and Electric Motor

In ventilation systems with variable demand, the use of adjustable speed drives is usually the best way to ensure maximum efficiency and minimum energy consumption.

Under such circumstances, it is essential that the designer has a broad view of the behavior of the fan to be selected.

Our software has the most advanced engineering charts with high resolution details, which show characteristic curves throughout the operating speed range of the fans.

Electric Motor Database

Since fans and blowers are often driven by industrial electric motors, the software has an extensive database containing data of electric motors from around the world.

IEC

  • 11 Types of Degree of Protection
  • 2880 Electric Motors

NEMA

  • 11 Types of Enclosure
  • 3240 Electric Motors

Fan's Design Setup

Operating Fan

In addition to the operating conditions, the software allows the user to set up construction features and choose components for each fan, such as:

  • Drive Arrangement AMCA
  • Inlet Box Position - Air Entry AMCA
  • Direction of Rotation and Discharge Position AMCA
  • Motor Position for Belt or Chain Drive AMCA
  • Far Field Sound Directivity Reverberant Room Method
  • Optional Accessories Selection Manufacturer

Reports

Fan Reports

Once the fan has been selected, the software automatically generates all the engineering reports, datasheets, charts and CAD drawings in several standard paper sizes.

The display and printing of reports use a WYSIWYG (What You See Is What You Get) interface:

  • Report of Design Data
  • Drawing of the Fan Impeller
  • Assembly Drawing of the Fan
  • Detail Drawing of Shafts and Hubs
  • Charts of Performance Curves
  • Calculation Report of Sound Spectrum

All of these documents can be easily customized, printed, emailed or exported to formats like:

  • PDF - DOC - XLS - JPG - GIF - TIF - PNG - FAX - etc.

GUI - Graphical User Interface

Software Tools

Built with multilingual user interface and an advanced unit converter, our software is fully capable to meet the needs and requirements of any manufacturer in the world, regardless of the volume of its production or the variety of its product range.

Software Tools

  • Multilanguage Support
  • Units of Measurement and Significant Digits
  • History Input Data
  • Custom Reports
  • Print Preview
  • Design Wizard
  • CAD Export

FEG - Fan Efficiency Grade

Our industrial fan software is also prepared to meet the latest American requirements for fan efficiency classification.

The FEG classification system can be used by government agencies or regulatory bodies around the world to define the energy efficiency requirements of fans used in specific applications.

The FEG is a simple way to indicate the aerodynamic quality of the fan.

While the fan efficiency is a function of the operating point on the performance curve, the FEG is based only on the fan’s peak total efficiency.

Similarly, our software also meets efficiency requirements of the European countries that prefer the FMEG classification system - Fan Motor Efficiency Grade.

Normative References:

  • ANSI / AMCA 205 - Energy Efficiency Classification for Fans
  • ISO 12759 - Efficiency Classification for Fans
