In the late 60's, Kinetics introduced the first spring isolation rails which were installed between the rooftop equipment and the roof curb. These did an excellent job isolating the vibration from the rooftop equipment to the building structure; however, they did not address the problems of duct-borne noise or equipment breakout noise into the conditioned space.
Today, Kinetics introduces the ESSR. The ESSR incorporates all the features of our ESR vibration isolation curb with our Vibron aerodynamic acoustical silencers, return air plenums and High Transmission Loss (HTL) panels. This gives you a noise control system that addresses all the noise and vibration concerns of your packaged rooftop equipment: vibration from the rotating equipment and casing radiation, duct-borne noise from supply and return fans, and breakout noise from the fans and compressors into the space below.
You tell us the NC level you want, the packaged system you want to use and some information on the building construction and we select the ESSR package designed to meet your needs. As with the ESR, the ESSR can be designed to meet all seismic and wind load code requirements. The ESSR is a modular system based on your needs. You may not need the acoustical return air plenum and the aerodynamic supply silencer - one or the other may be sufficient. Depending on the roof construction and the space usage below the packaged unit, the HTL panels may not be required. We will select only the acoustical elements you need.
