Case Details

Product Introduction:

In response to the storage energy industry's need for fire protection systems to withstand various harsh conditions such as rain, snow, hail, and extreme cold and heat, there is an urgent market demand for upgrading explosion vent panels. Therefore, it is necessary to improve and upgrade the overall structure, climate protection, and usability of the DVPNL explosion vent panel to meet the higher fire safety requirements of the storage energy industry.

Technical Features:

Adopts a weather-resistant cover support structure to enhance resistance to hail/rock impact.
Uses new insulation materials and related structural designs to reduce the internal height occupancy of the box by approximately 20mm.
Employs a new sealing structure to improve sealing reliability.

Product Configuration:

Single-layer SUS 316L
Silicone foam UL94 V0 (-55℃ ~ +200℃)
Includes flange + silicone foam
Climate protection cover
Thermal conductivity of insulation cotton:

- ≤0.020 W/(m·K) (25℃)

- ≤0.023 W/(m·K) (100℃)

No water retention and anti-seismic design.

Explosion Vent Panel Device Selection Guide:

First, select the category of explosion vent panel product, and choose either upper insulation or lower insulation based on your needs.

The thickness direction of the upper insulation explosion vent panel is above the installation interface, which provides better and more reliable environmental weather resistance for long-term outdoor use. The thickness direction of the lower insulation explosion vent panel is below the installation interface, which saves space above the box for easier transportation and placement.

Secondly, provide the corresponding parameters and select the size of the explosion vent panel through compliant calculations.
