Overview
Acoustic enclosure boxes provide the most cost-effective means of noise control for individual machines and equipment items. Unlike room-level treatment, a close-fitting enclosure concentrates acoustic material at the noise source, maximizing insertion loss with minimum material use.
HEMU Acoustics enclosure boxes use a modular panel system with click-locking steel frames. Standard panels achieve 20–35 dB insertion loss; high-performance double-skin panels achieve up to 40 dB. Hinged access panels and removable sections are designed into the enclosure for routine maintenance without full dismantling.
The enclosure is sized to clear the machine by 150–300 mm on all sides, enabling natural convection cooling for most applications. For high-heat applications, ventilation packages with acoustic attenuators are integrated into the enclosure design. All cable and hose penetrations are sealed with acoustic putty collars.
ATEX-certified variants are available for machines in hazardous areas (Zone 1 and Zone 2). Panels are manufactured in chemical-resistant powder-coat finish as standard, with stainless steel available for food, pharmaceutical, and marine environments.
Key Features

Hinged Maintenance Access
Pre-designed hinged panels and lift-off sections for routine maintenance points. Acoustic seals maintained at all access points.
Thermal Management
Natural convection sizing standard. Forced ventilation package with inlet/exhaust attenuators available for high-duty-cycle or high-heat machines.
ATEX Variants
Zone 1 and 2 ATEX enclosures with explosion-proof lighting fixtures and intrinsically safe temperature monitoring.
Chemical-Resistant Finish
Epoxy powder-coat for standard industrial use. 304/316 stainless steel panels for food processing, pharmaceutical, and offshore marine applications.
Custom Configuration
Enclosures designed to machine footprint with all penetrations, control panel cutouts, and access requirements incorporated in the factory model.
