ALL NOISE CONTROL
SILENCOR® METAL ENCLOSURE
Silencor® Metal Enclosures are engineered industrial acoustic enclosure systems designed to reduce high-level equipment noise in commercial and industrial environments. Constructed with modular double-walled acoustic panels, these enclosures deliver effective sound absorption, strong sound transmission loss (STC performance), and reliable low-frequency noise control.
Commonly used for generators, HVAC systems, compressors, pumps, and mechanical equipment, each enclosure is custom-designed to meet acoustic performance targets while maintaining proper ventilation, structural integrity, and maintenance access. Silencor® Metal Enclosures provide durable, code-compliant solutions for OSHA noise reduction, property-line compliance, and outdoor equipment noise control.
Application
Silencor® Metal Enclosures are engineered to isolate and contain high-decibel equipment noise in both indoor and outdoor industrial environments, supporting OSHA compliance, property-line sound limits, and overall workplace noise reduction.
Indoor Applications
For mechanical rooms and in-plant environments, Silencor® Metal Enclosures provide effective indoor equipment noise control while maintaining ventilation and maintenance access. Common uses include:
- Generator rooms
- HVAC and air handler enclosures
- Compressor and pump isolation
- Manufacturing machinery containment
- In-plant offices and control room isolation
Outdoor Applications
Designed for exterior exposure, outdoor metal enclosures are built to withstand wind and snow loads, UV exposure, and moisture conditions while delivering consistent acoustic performance. Typical outdoor applications include:
- Standby and continuous power generators
- Cooling towers and chillers
- Mechanical yard equipment
- Industrial blowers and fans
- Process equipment enclosures
Key Features of Silencor® Metal Enclosures
Silencor® Metal Enclosures are engineered for high-performance industrial noise control, combining durable steel construction with proven acoustic panel technology for indoor and outdoor applications.
Double-Wall Acoustic Panels – Solid outer steel shell with perforated inner liner and high-density acoustic fill for strong sound absorption and reliable STC-rated transmission loss.
High-Performance Noise Reduction – Designed to control both mid- and low-frequency equipment noise, including generators and heavy mechanical systems.
Integrated Ventilation – Configurable with acoustic louvers, silenced airflow paths, and forced ventilation systems to maintain proper cooling while reducing noise.
Heavy-Duty Construction – Available in galvanized or stainless steel with corrosion-resistant finishes for long-term durability and structural performance.
Custom & Code-Compliant Designs – Fabricated to meet project-specific acoustic targets, ventilation needs, and OSHA noise reduction requirements.
Compliance And Regulations – All Noise Control Silencor® Metal Enclosure
Silencor® Metal Enclosures are engineered to meet or exceed applicable safety, structural, and acoustic performance standards for industrial and commercial environments. Each enclosure system is designed to support OSHA noise exposure compliance, helping facilities reduce hazardous sound levels and improve workplace safety.
Panel assemblies are tested in accordance with recognized ASTM acoustic standards to verify sound transmission loss (STC performance) and sound absorption characteristics. For electrical and control applications, enclosures can be configured to align with UL and NEMA requirements, while outdoor systems are engineered to withstand wind loads, snow loads, and environmental exposure in accordance with building code standards.
Certified acoustic test data and engineering documentation are available to support compliance verification and project submittals.
Custom Steel Enclosures With Advanced Performance Features
Silencor® Metal Enclosures are fully customizable steel acoustic enclosure systems engineered to meet specialized performance and protection requirements. In addition to high-STC acoustic panel construction, enclosures can be configured with advanced options such as RFI/EMI shielding, X-ray shielding, ballistic-rated panels, and enhanced structural reinforcement for mission-critical applications.
Each system can integrate custom ventilation packages, acoustic louvers, electrical components, lighting, load centers, and removable service panels, ensuring proper airflow, operational efficiency, and long-term durability. These advanced configurations make Silencor® Metal
Enclosures suitable for high-security facilities, power generation plants, healthcare environments, and heavy industrial installations where both acoustic performance and structural integrity are essential.

FAQS
What is a Silencor® Metal Enclosure?
- A Silencor® Metal Enclosure is a custom-engineered industrial acoustic enclosure system designed to fully surround noisy equipment such as generators, HVAC units, compressors, and pumps to provide effective noise reduction and sound transmission loss (STC performance).
How much noise reduction can a metal enclosure provide?
- Depending on panel thickness and configuration, Silencor® Metal Enclosures typically achieve 20–35 dBA noise reduction or greater. Final performance depends on equipment type, ventilation design, and site-specific acoustic requirements.
Are these enclosures suitable for outdoor installations?
- Yes. Silencor® Metal Enclosures are designed for outdoor equipment noise control and can be engineered to withstand wind loads, snow loads, UV exposure, and moisture conditions while maintaining structural integrity and acoustic performance.
Do the enclosures meet OSHA noise regulations?
- Silencor® Metal Enclosures are engineered to help facilities achieve OSHA-compliant noise levels by reducing hazardous sound exposure around generators, compressors, and other industrial equipment.
Can ventilation systems be integrated into the enclosure?
- Yes. Enclosures can be configured with acoustic louvers, silenced ventilation systems, forced airflow packages, and plenums to maintain proper cooling while controlling equipment noise.
Are custom sizes and configurations available?
- Absolutely. Each Silencor® Metal Enclosure is custom-fabricated to meet project-specific dimensions, acoustic targets, ventilation requirements, and structural loading conditions.
Is certified acoustic test data available?
- Yes. All Noise Control provides independently verified acoustic test data, including STC ratings and sound absorption performance, to support engineering documentation and compliance submittals.
