Dräger HC-COM

Hands-Free Helmet Communication for Extreme Environments

The Dräger HC-COM is a compact, lightweight helmet communication unit designed specifically for firefighters, rescue teams, and industrial emergency personnel. Engineered to facilitate crystal-clear voice transmissions in high-noise and hazardous environments, this communication module integrates seamlessly inside protective helmets. By establishing a direct, hands-free link to tactical radios, it ensures operational synchronization and improves team safety when executing critical fire ground or hazardous material operations.

Advanced Audio Clarity and Bone Conduction Technology

At the center of the HC-COM system is an innovative bone-conduction microphone or a high-performance boom microphone variant designed to capture speech directly through cranial vibrations or close-range acoustics. This specialized pickup methodology filters out loud background plant noise, rushing water, and roaring flames. Paired with a localized, flame-resistant ear speaker, the unit delivers clear audio directly to the wearer without blocking ambient spatial awareness or competing with standard acoustic PPE barriers.

Rugged, Intrinsically Safe Architecture

Built to withstand intense physical and environmental strain, the Dräger HC-COM features a ruggedized, water-resistant housing certified for explosive atmospheres. The unit connects effortlessly via quick-connect cabling to standard external push-to-talk (PTT) buttons and major industrial long-range tactical radio systems. Its low-profile, clip-in mechanical design allows it to mount inside fire helmets without creating pressure points on the user's head or interfering with the tight seal of a full-face SCBA respiratory mask.

Industrial Applications and Use Cases

• Structural Firefighting: Maintaining vital command communications while operating inside smoke-filled, high-noise structures.

• Technical Rescue Interventions: Enabling clear team coordination during tight confined space extractions or vehicle extrications.

• Hazardous Materials Response: Ensuring secure, intrinsically safe communication inside fully encapsulating gas-tight chemical suits.

• Industrial Plant Emergency Response: Linking facility emergency brigades directly to control rooms during high-stress industrial refinery incidents.
