AtlasIED HLE-3 60W Explosion-Proof Compression Driver – 16 Ohm

The AtlasIED HLE-3 is a UL-listed, 60-watt explosion-proof compression driver engineered for high-intelligibility voice communication and electronic signaling in hazardous industrial environments. Designed for Class I, Groups B, C, and D hazardous locations, the HLE-3 provides a specialized audio solution for facilities where flammable gases or vapors require appropriately rated equipment.

Featuring a 16-ohm voice coil, rugged die-cast aluminum housing, factory-installed pipe seal with integral field wiring leads, and adjustable mounting bracket, the HLE-3 is designed for demanding industrial communication applications.

The driver delivers a 250 Hz–12 kHz frequency response and supports two compatible AtlasIED explosion-proof projector horns, allowing system designers to select the appropriate sound dispersion pattern.

The HLE-3 is particularly suited for industrial paging, warning signals, and voice communication systems in hazardous environments, including locations where hydrogen may be present.

Important: The AtlasIED HLE-3 is a compression driver only. A compatible HLE/MLE-30 or HLE/MLE-32 projector horn is required and sold separately.

60-Watt Compression Driver for Hazardous Locations

The AtlasIED HLE-3 provides 60 watts of continuous power handling with a 16-ohm voice coil for compatible low-impedance audio systems.

Its high-efficiency design supports voice announcements and electronic signals in industrial environments where communication equipment must meet specific hazardous-location requirements.

Unlike conventional commercial compression drivers, the HLE-3 incorporates an explosion-proof enclosure designed for use in the hazardous locations covered by its UL listing.

This makes it suitable for appropriately designed industrial communication systems where equipment selection must account for potentially combustible atmospheres.

UL-Listed for Class I, Groups B, C, and D Environments

The HLE-3 is UL-listed for specified Class I hazardous locations, Groups B, C, and D, including certain environments where flammable gases or vapors may be present.

Its Group B classification is particularly important for applications involving hydrogen atmospheres.

The driver is listed to UL 1203 for applicable hazardous-location use.

Proper installation must follow the manufacturer's instructions, applicable electrical codes, and the requirements of the authority having jurisdiction.

Safety Note: The HLE-3's hazardous-location approval does not mean it is suitable for every classified environment. Always verify the complete location classification and approved installation requirements before specifying equipment.

Rugged Die-Cast Aluminum Construction

The AtlasIED HLE-3 features a heavy-duty die-cast aluminum enclosure designed to protect the compression driver in demanding industrial applications.

Its construction includes:

• Explosion-proof die-cast aluminum driver housing
• Factory-installed pipe seal with integral field wiring leads
• Adjustable mounting bracket for positioning
• Construction intended for compatible hazardous-location installations

The adjustable mounting bracket allows the driver and attached projector horn to be directed toward the required listening area.

Two Compatible Horn Options for Different Coverage Requirements

The HLE-3 accepts two AtlasIED projector horns designed for the HLE/MLE explosion-proof driver series.

AtlasIED HLE/MLE-30 Wide-Angle Projector Horn

The HLE/MLE-30 is a polycarbonate projector horn providing a 120° horizontal × 60° vertical dispersion pattern.

This configuration is appropriate for applications requiring broad directional coverage across industrial work areas.

When paired with the HLE-3, the assembly has a specified sensitivity of 108 dB.

AtlasIED HLE/MLE-32 Circular Projector Horn

The HLE/MLE-32 is a spun-aluminum bell projector providing 95° circular sound dispersion.

This configuration is suitable for installations requiring a more concentrated circular coverage pattern.

When paired with the HLE-3, the assembly has a specified sensitivity of 111 dB.

Important: Only the AtlasIED HLE/MLE-30 and HLE/MLE-32 projector horns are UL-listed for use with the HLE/MLE explosion-proof driver series.

Need a Compatible Explosion-Proof Projector Horn?

The AtlasIED HLE-3 requires a compatible projector horn, sold separately.

Choose the AtlasIED HLE/MLE-30 for wide-angle 120° × 60° sound dispersion, or the AtlasIED HLE/MLE-32 for 95° circular coverage.

Both horns are specifically listed for use with the HLE/MLE explosion-proof driver series.

Selecting the correct horn is essential for achieving the intended coverage and maintaining the applicable UL-listed configuration.
