Generators, pumps, and other industrial applications involving a large engine share one notable commonality: they are loud.

Products that operate for extended periods at over 70 decibels often require a sound attenuated enclosure, which not only protects equipment but also shields the surrounding environment from harmful sound waves.

Ameritex supports customers who provide “engineered to order” products to their end user with project based orders from quantity of one to several hundred enclosures. These projects often have a demanding delivery schedule that we pride ourselves on being able to meet or exceed.

Sound Attenuated Enclosures: What to Tell Your Metal Fabricator

Thinking of outsourcing your next sound attenuated enclosure to us? Provide this information up front to receive an accurate estimate and streamline the manufacturing process.

1. Doors, covers, and other equipment access

It’s important for us to understand the equipment layout, including where access is required for critical operation and maintenance, such as starting up/shutting down the equipment and changing filters. Additionally, be sure to specify door and cover locations and sizes.

Clarifying these details reduces the need for revisions down the line and helps you avoid the surprise of additional charges.

2. Hardware requirements 

We’ll need to know your hardware requirements to estimate your cost and lead time accurately.

For example, certain 3-point latches and stainless steel hardware can be expensive and difficult to source. Our customers appreciate when we’re transparent about how these factors will impact them up front, and we can only do that when we have the necessary information.

3. Insulation type 

If you have specific thickness and sound requirements for your insulation, let us know those requirements and if there is an insulation type you desire.

There are many options for sound attenuation, including Rockwool, polyurethane, and polypropylene sheets. We can combine these options with mass-loaded vinyl or rubber to control sound through exhaust vents, dampers, and louvers.

4. Opening sizes for air and/or flow rates 

It’s no secret that airflow is critical to keeping equipment cool. Be sure to relay air and opening requirements to us so that we can incorporate them into your enclosure.

5. Drop-over or skid-mounted 

Should we build your sound attenuated enclosure to sit over an existing piece of equipment already on its own skid, or should we ship it to you mounted to a skid?

These two options have significant price differences, so specifying your requirement up front is important. If you already have a skid, include a drawing or—even better—a model to ensure the enclosure properly mates to the skid.

6. Plans for lifting your sound attenuated enclosure

Enclosures can weigh up to 50,000 pounds, so careful forethought about how to transport them is an absolute must.

Let us know how you intend to lift your enclosure so we can incorporate proper lifting provisions into the fabrication. Roof-mounted lifting lugs, side-mounted lifting lugs, and fork pockets are just a few available options.
