The State of Pre-Engineered Systems with Jamie Knowles

On September 30, 2022, the rules changed for fire sprinkler antifreeze systems. Sean Pearce of Lubrizol joins me to discuss the updates to NFPA 13 & 25 and how they will affect contractors and building owners moving forward. How do companies test new and old antifreeze moving forward? When are antifreeze systems required to remove and change out to the new UL-Listed products? What design variables are involved when engineering a new fire sprinkler system that is susceptible to the cold? How do you currently analyze your antifreeze testing? Are you grabbing data points to compare? All of these any more are discussed. Watch and listen here. 

Lubrizol has created an incredibly informative presentation called Listed Antifreeze for Fire Sprinkler Systems. You can download a copy here.
