Caterpillar’s New Enclosures for Cat® 3516C Generator Sets Supply Premium Sound Attenuation, Access, Security, and Protection from Elements

For Worldwide Release: June 5, 2024

IRVING, TEXAS – Caterpillar Inc. today introduced a new enclosure for Cat® 3516C diesel generator sets for use in 60 Hz standby and mission-critical applications. Available now from Cat dealers in North America, the walk-in enclosure is engineered by Caterpillar to provide superior sound attenuation, access for operation and maintenance, security, and protection from the elements.

Designed for the Cat 3516C generator set operating at 2.0 MW, the enclosure features a compact footprint that helps to reduce shipping and installation expenses, and it can be configured with an optional, integrated fuel tank base that provides up to 24 hours of run time.

The new enclosure is designed for maximum ambient temperatures up to 113 degrees Fahrenheit (45 degrees Celsius), with optional cold-weather kits available for severe-duty operation. Two levels of sound attenuation are available: 79 dBA and 74 dBA at 23 feet (7 meters). Additionally, it has been designed to comply with the International Building Code’s (IBC) 120 mph wind-load provisions and is UL 2200 Listed.

This enclosure design can also be easily adapted for Cat 3516C generator sets operating at 2.5 MW. It is ideal for outdoor operating environments across a broad range of industrial applications, including healthcare, education, communications and data centers, among many others.
