No matter the industry, fans play an important role in the process. Often they are the critical item in the system, a system that simply cannot be allowed to go down for any extended period of time.
PARAG Fans utilize the latest in CAD and FEA technology to model the Fan calculating stress levels and optimizing material selections. PARAG Fans can perform a frequency analysis to ensure natural frequencies are well removed from operating speeds and other sensitive frequencies like a 2x and blade pass. |
| |
| Retrofits, modifications include: |
 |
Installing higher efficiency Fans in same casing /stack |
|
Increased throughput using “Tipping” techniques |
|
Efficiency Improvements |
|
Resizing Fan for actual operating conditions versus original design |
