IAC Acoustics Moduline® Acoustic Enclosures

SKU: ENCIACMOD

Typical Shipping Lead Time: 5-8 weeks after approval of design drawings

IAC Acoustics Moduline® Acoustic Enclosures protect workers and the community from noise generated by manufacturing and power generating machinery. In industrial settings, noise from this equipment frequently exceeds OSHA limits for hearing safety while also impeding communication. Without noise control remediation, local noise ordinances at plant property lines may be exceeded. Acoustic enclosures are an effective and efficient way to address these problems.

Access to over 12 different acoustic panel constructions provides options to find the most cost-effective solution to treat any given noise control problem. IAC Acoustics Moduline® Acoustic Enclosures are a modular system with a single-piece roll-formed “H” joiner for certified acoustic performance. This reduces the risk of compromised performance over a “stick-built” solution, where performance is based on varying assumptions and trade practices. Systems may be ordered with Noise Lock sound control door and window systems, permitting access and visibility while maintaining acoustic isolation. Enclosures may be outfitted with floating floors, HVAC silencers, ventilation, UL rated assemblies, blast protection, air conditioning, lighting and much more.

The Moduline® enclosures typically ship knocked-down as a set of components for simple and cost-effective shipment and assembly. Designs may be produced for both interior and exterior installation sites. Typical applications for IAC Acoustics Moduline® Acoustic Enclosures include diesel engine gen-sets, compressor enclosures, in-plant personnel noise shelters, control rooms, operator pulpits, vehicle and component test cells, and other noisy equipment.
