The California Office of Statewide Health Planning and Development (OSHPD) announced that another YORK large-tonnage, water-cooled chiller, manufactured by Johnson Controls, earned OSHPD Special Seismic Certification Preapproval. The YORK model YMC chiller (reference: OSP-0159-10) joins the Johnson Controls list, which currently includes the YORK model YK centrifugal chillers with variable-speed drives (OSP-0045-10).
The OSHPD Special Seismic Preapproval certifies that approved equipment will function after an earthquake of a specified level. To earn Special Seismic Certification Preapproval, several models within the product line were required to successfully demonstrate functional operation after a shaker-table test, which simulates an earthquake. YORK chillers were tested on both neoprene pads for rigid-mount applications, as well as springs for above-grade applications.
The President / CEO of MakeItRight, Inc. and Managing Partner of Dynamic Certification Laboratory, Joseph La Brie, SE, said, "Johnson Controls has been vigilant to properly capture the complex arrangement of equipment components in ways that many companies have not done. Consequently, the company has held suppliers of these components to the same rigorous standards to which it holds itself. The YMC chiller is only one of several products that have demonstrated the reliable performance of the product and its components under laboratory simulation of earthquake conditions."
Although the OSHPD Special Seismic Preapproval certification is regulated by the state of California, compliance with OSHPD's provisions also offers full compliance with the International Building Code (IBC) for seismic applications in other areas that are at a higher risk for earthquakes, including the Pacific Northwest, Alaska, St. Louis, Charleston and Memphis.
