The JTS Seismic Series chillers are based on the Signature Series with frame and mounting modifications to withstand seismic displacement. The Seismic Series line has the California Office of Statewide Health Planning’s Seismic Pre-approval (OSP 0173-10) as well as Pre-approved Anchorages (OPA-2674-10 and OPA-2675-10). JTS’s Seismic Series models measured a 2.7 sds and 3.0 sds, depending on the model. See for yourself how well the Seismic Series did under shake table testing on our Johnson Thermal YouTube channel. See our OSP, OPA or Seismic Certification documents for more details, or consult the factory.
