• _MG_1981Koch Personnel Enclosures, Control Pulpits and In-Plant Offices are a cost effective alternative to controlling noise at the source. The units are designed for extreme environments, providing noise, vibration, thermal, dust, and humidity isolation. Typical applications include paper mills, steel mills, printing plants, power plants, metalworking plants, foundry’s, mines, and all manufacturing operations with unique isolation and security requirements.

    The units are offered in seven standard sizes and shipped pre-assembled or knocked down. Constructed of Koch’s unique pre-fabricated modular acoustical panels and accessories, custom layouts are easily configured and most common.

    Koch units feature all steel non-combustible construction with a baked on powder coat finish. Applications that require high sound reduction, sound absorption, acoustical windows, acoustical doors and acoustical roofs are our specialty.

    Through decades of experience and product development, Koch Personnel Enclosures exceed customer expectations in all aspects including sound attenuation, sound absorption, appearance, cleanability, abuse resistance, cost, and ease of installation.
