TEC Minneapolis Three Fan Blowout Wind System

The three fan blower system consists of three Model 3 fans and two digital DG-1000 pressure gauges, used for measuring the airtightness of buildings with an enclosure area of approximately 36000m ² or an internal volume of up to 440000m ³. The MultipleFan system is designed as a modular system, so it can not only measure large industrial and office buildings, but also use one or two fans, and can be used in single family residential or apartment buildings.

Using a three fan blower system (three Model3 fans) and TECLOG software, you can perform and record air tightness measurements at a flow rate of approximately 21600 m ³/h.

Fans are centrally controlled by computers or mobile phones through WI-FI/Bluetooth or data cables. In order to measure the airtightness of large residential or commercial buildings, multiple systems can be easily combined if necessary, up to a maximum of 16 fans can be combined simultaneously.

Meet the standards ISO 9972 and EN 13829

Use TECLOG MultipleFan software to measure the air tightness of large buildings with multiple fans. The main fan control function can centrally control all blower door fans from one laptop computer at the same time. A new feature is to control the blower door fan through the integrated WLAN module of DG-1000. Your laptop can be easily placed anywhere in the building, with fan speed controlled by the computer and real-time flow displayed on the DG1000 screen. By using the POR (Recording Cycle) function, pressing the button can record the required measurement cycle. Users can easily measure any deviation caused by wind or door opening, and can quickly respond to interference during the measurement process.

The total air flow is automatically obtained and the measurement chart can be accessed at any time by clicking the mouse. It is necessary to quickly analyze the measurement results in order to make on-site decisions on whether they are accurate and whether the results meet the requirements. After the measurement is completed, the data is read into Tecite Express 5.1 to create a test report. The new version of TECLOG software has completed other functions, such as recording the pressure difference of several buildings on different sides of the building and analyzing the pressure distribution inside the building.

The airtightness performance of buildings is crucial for achieving ultra-low energy consumption goals. Good air tightness can reduce the infiltration of cold air in winter, reduce the increase in cooling demand caused by uncontrolled ventilation in summer, avoid building mold, condensation, and damage caused by moisture infiltration, reduce the impact of adverse factors such as outdoor noise and air pollution on indoor environment, and improve the quality of life of residents.

TEC Minneapolis Three Fan Blowout Wind System

Important functions:

• Measurement of blast doors according to ISO 9972 and EN 13829 standards

• Clear and compact testing setup

Combination of different pressure gauges (DG500, DG700, DG1000)

• Control all fans simultaneously from one laptop

• Data communication through cables or integrated WLAN modules

• Automatic recording of measurement cycle

Real time display of air flow allows you to analyze measurement results on-site

Recording several building pressure differentials can help measure oversized buildings with complex floor plans

The testing system with three fans allows you to distribute fans (2+1) in different doorways to achieve constant pressure distribution in very large buildings

Data and annotations are recorded in one file

Automatically close when the maximum pressure is reached

Door frame and door cloth:

Frame material: extruded aluminum

Width: 28 inches to 40 inches Height: 52 inches to 96 inches

Door fabric material: Heavy duty coated nylon

Universal modular design:

The large Minneapolis blast door measurement system is very suitable for measuring large industrial and commercial buildings: you can combine any number of blast door fans and pressure gauges separately according to your needs and requirements. By calibrating the measuring fans and pressure gauges separately, even when multiple system components are combined, we still maintain the accuracy of the blast door measurement technology.

According to the on-site situation, the blast door measurement system is installed in one or more door openings. In large buildings with complex floor plans, the distributed measurement system in the building can achieve constant pressure distribution.
