and industrial fan manufacturers from Reitz india.
In sectors that use industrial fans, boosting the energy efficiency of 
these blowers is a major focus. Many plants and factories are now 
opting for retrofitting industrial blowers as a cost-effective 
alternative to deploying new fans. Retrofitting includes upgrading 
parts or various industrial blower systems. 
Why Retrofit Industrial Fans? 
Let us now explore why plants and factories are required to retrofit 
these blowers
Due to wear and tear, the performance of these fans gradually 
deteriorates over time. Additionally, if there are changes in 
production specifications, the existing blowers may no longer be 
adequate to meet the new requirements.
The power consumed by these older blowers is on the higher side, 
as well.
However, retrofitting these devices helps resolve these issues. The 
fans again deliver optimal performance, and their energy costs also 
come down. Overall, retrofitting extends the longevity of industrial 
fans.
•Retrofitting Industrial Fans – Salient Aspects 
•These are a few salient aspects about retrofitting these blowers:
•The impeller designs can be upgraded to achieve enhanced aerodynamics.
•When high-capacity motors are installed, the performance of blowers is boosted.
•Businesses have the option to integrate Variable Frequency Drives (VFDs) into 
blowers, allowing operators greater control over the fans.
•Retrofitting is significantly more cost-effective than purchasing new industrial fans, 
and plants can recover the costs in a relatively short period.
•Retrofitting Fans – More Benefits 
•It will now be worthwhile to glance at some more benefits of retrofitting blowers.
•Retrofitted fans can significantly reduce power consumption by approximately 15–
30%. It is important to note that installing the latest impellers in fans can greatly 
enhance energy efficiency.
A Case Study
•At this juncture, it will be helpful to briefly elaborate on a case study. A power plant 
greatly benefited from choosing to retrofit its existing blowers.
•A power plant started to notice an abnormal increase in energy costs because of 
improper operation of blowers. It was advised that retrofitting these devices would 
resolve the issue.
•As per the guidelines, aerodynamic impellers and Variable Frequency Drives were 
fitted.
•In a relatively short period, energy consumption was reduced by about 25%. This 
was accompanied by improved airflow management, lower emissions, and 
enhanced combustion efficiency.
•Plants and factories experiencing these issues are advised to retrofit their blowers 
as soon as possible. In today’s competitive market, retrofitting provides businesses 
with a much-needed advantage. There are now many providers offering retrofitting 
services. They offer solutions customized to meet the unique needs of each 
business.
