How to prevent imploded ducting
a. Introduction
Ducts typically implode when the internal pressure drops significantly below the external pressure. This can happen due to:
- System Shutdowns
- Improper Design
- Damper Malfunction
- Rapid Depressurization
b. Challenge
- Want to prevent the imploding of duct
- There are some requirements for static pressure that need to be set
c. Solution
- Pressure differential can be adjusted at the site with the help of counterbalance and weight based on site requirements
- Greenheck can set the temperature above -40 to 121°C
- Greenheck can custom-size the damper dimensions (width and height) to match the exact width and height of the ducting, ensuring a perfect fit for the system.
- Can set velocity up to 6400 fpm
