DEFLAGRATION VENT PANELS

WITH INTERNAL THERMAL INSULATION

ALUMINUM BOX

Insulation protection box below the vent panel (Internal insulation)

ARC-VENT® INS-B aluminum explosion vent panel for industrial pressure relief and safety.

APPLICATIONS

To optimize our product range, we offer the ARC-VENT® INS – B panels with insulation protection box below the vent panel, specifically engineered for superior thermal performance. Designed to meet the internal environment control requirements of your BESS, we have enhanced the thermal insulation properties of our panels to ensure optimal enclosure protection.

As an alternative to INS -A version, the INS – B model incorporates mineral wool encased in an aluminum box, providing equivalent insulation performance without the use of synthetic rubber foam. INS -B is available in various insulation thicknesses to suit your specific needs, all while maintaining the panel’s efficiency during explosion events
