What is "Project Warnock Hersey"? No, it's not a top-secret mission, whereby Ruskin sends Rick Cravy back in time with a CD50 in hand to change the future of the damper industry (that's already been done). "Project: Warnock Hersey" is an example of how Ruskin continues to provide new products while moving in the direction the market mandates. "Project: Warnock Hersey" is Ruskin doing what other manufactures struggle to do.

Warnock Hersey, like UL, is an independent agency which evaluates and tests products to recognized standards including those dictated by UL, NFPA, ASTM, etc. If the product meets the minimum requirements set forth in the referenced standards or other Warnock Hersey specifications, then Warnock Hersey will list the product, and the Warnock Hersey certification mark can be affixed on it.

In the case of "Project: Warnock Hersey," an application of ceiling fire dampers into a residential building required a label. The job was a huge apartment complex in Tampa, FL called the Vinings Club at Boot Ranch. The application involved utilizing a CFD at a ceiling penetration off the top residential air handler. The duct penetrated the fire-rated ceiling then ran through the rest of the apartment.

No CFD had been approved for use in this application, but by working with the design engineer and the authorities having jurisdiction, this opportunity presented itself. The hard work resulted in thousands of Warnock Hersey - labeled CFDs for the Vinings Club at Boot Ranch.
