PyroCide Vent Panel

Fire-block meets stringent flame safety standards

Custom PyroCide Vent Panels are the ideal solution for electronics enclosure applications required to meet stringent flame safety standards. Custom PyroCide Vent Panels are aluminum honeycomb thermal barriers treated with a heat responsive intumescent flame coating for fire containment in electronics enclosures. Products are designed with thin profiles and configured with aluminum honeycomb to provide low resistance to airflow. Edge-to-edge venting requirements and intricate designs are met with precision metal fabricated aluminum frames and housings.

The PyroCide coating has an ASTM E-84 Class A rating with low flame spread and low smoke index values. A thin coating in the honeycomb cells reacts on exposure to flame or excessive heat and expands rapidly, filling the cells with foam that prevents flames from propagating through the Vent Panels. Currently, there are no established test criteria for intumescent coatings or honeycomb vent panels.

Air straightening and air diffusion are a standard feature for applications requiring thermal management. Products are custom designed to meet specific application needs and are configured with spring clips and other attachment hardware to improve installation and contact. PyroCide Vent Panels typically use 0.12” cell honeycomb in 0.12” and 0.25” thickness but other components like slanted 45 or 30 degree honeycomb and mesh screens are also specified.

Roll formed into a strong sturdy one-piece channel, using 0.025″ thick (0.032” thick for FF-2X), 3000 series aluminum. Frame is tightly fitted to filter media and fastened with an aluminum rivet. Part number is metal stamped into frame for quick, accurate identification.

In addition to the standard roll formed frame design, more custom options are also available.  The Windowpane style frame allows for highly customizable, non-rectangular frame profiles.
