BD1 Explosion-Proof Door – Explosion Protection for Bunkers and Shelters

The BD1 explosion-proof door was developed to protect people and property in safety-critical structures. It offers high resistance to explosion pressure waves and is particularly suitable for bunkers, shelters, critical infrastructure, and industrial safety zones.

The solid, multi-layer construction is based on proven vault-building principles. The door has been tested by Fraunhofer EMI and meets resistance class EPR2 according to EN 13123-1. It offers blast resistance of over 1 bar for a duration of 25 ms.

Design and Explosion Protection

The 88-mm-thick door panel features a solid, multi-layer construction. A robust door panel and a sturdy frame construction form the basis for its high durability. In addition, a multi-point locking system with solid locking bolts 38 mm in diameter ensures secure locking.

Two sturdy, safe-style hinges ensure reliable door operation. In addition, there are extra locking bolts on the hinge side. These increase resistance to forced entry attempts.

Waterproofing and Ease of Use

The BD1 explosion-proof door features all-around seals. A movable, retractable floor seal complements the sealing system. At the same time, the threshold-free design allows for easy passage.

A sturdy steel handle on the inside makes it easy to operate. This makes the door suitable even for security-sensitive areas with specific requirements for accessibility and functionality.
