Overview
The Blast Shutter is designed to deform plastically under blast pressure, absorbing energy while preventing component failure.
The curtain is supported by horizontal steel connector rods that are attached to vertical wire ropes at both sides. The wire ropes are restrained at the top and either unrestrained (for PL1) or tethered (for PL2) at the bottom.
PL1 – Blast Mitigating
- No bottom restraints
- Absorbs blast through large displacement
- Minimizes structural reaction
- Allows post-blast egress
Tested to:
- Peak pressure: 75 kPa
- Peak impulse: 1050 kPa-ms
PL2 – Blast Resistant
- Includes automated bottom restraints
- Limits displacement and intrusion
- Fully retained under blast load
Tested to:
- Peak pressure: 40 kPa
- Peak impulse: 500 kPa-ms
Applications
- Oil and Gas Plants
- Chemical Processing
- Defence and Military
- Energy Infrastructure
- Industrial Zones with Explosion Risk
