How do you achieve such high energy savings with your FRP fans?
We achieve high energy savings by our state-of-the-art aerodynamically designed fan blades customised to meet the application and system requirements.
What parameters should I provide in the fan selection for my system?
Application, Fan diameter, Airflow rate, Static pressure, RPM and motor specifications are required for selection of right fan to deliver excellent performance.
What is the airflow rate?
Airflow rate is the volume of air passing through the system over a unit time.
What is static pressure? How is it different from Total pressure?
Static pressure is the summation of all the system resistances which the fan must overcome to provide the required airflow expressed in Pascal or mmWC.
Dynamic pressure is the pressure exerted by the moving air in the direction of its motion. Total pressure is the summation of static and dynamic pressure.
What is Fan Brake Horsepower? How do you calculate it?
Fan Brake Horsepower or Fan shaft power is the minimum net power required by the fan to operate. It is calculated by the BHP = Q × TP/ ?
Where Q- Airflow rate, TP- Total Pressure and ?- Fan efficiency.
How do you select the number of blades?
The two main factors responsible for selection in the number of blades are system pressure requirement and power per blade.
How do you select the MOC of the fan assembly?
We select the MOC of our fan assembly as per the type of process and based on a thorough analysis of water chemistry.
What is the effect of power saving on my existing motor?
The power saving through FRP fan for maximum air flow rate reduces the motor loading and may require a lower rated motor for the same system.
I use a VFD system in my fan, why do I require an energy saving fan?
Variable frequency drive (VFD) saves energy by controlling the RPM of the fan, which can be used as per the season and variation in heat load. Energy saving fans can save additional power and further improve the system efficiency.
How do I avoid resonant frequency problems in the VFD system?
To avoid resonant frequency, we provide a Campbell diagram of our fan to check the percentage difference between the closest resonant frequencies of 1st mode resonant frequency, blade and beam pass frequencies, and 1x Harmonics.
How do you take care of Noise limit specification with your fan?
Along with efficiency, our rectilinear fan blade also fulfils the criteria of low noise. For further reduction in SPL, we have swept blade design.
