This webinar will focus on the benefits of PEX in hydronic applications, including fan-coil units, VAVs, AHUs, unit heaters, radiant manifolds, and more and explore the differences and similarities of using PEX compared to other piping materials.
On Demand It’s not the heat, it’s the humidity! At Pfizer Pharmaceutical, this isn’t simply a notion of comfort, it’s a battle cry for engineers responsible for controlling the indoor environment at the company’s pill-manufacturing facility in Puerto Rico. So, when Pfizer began a large HVAC renovation, the company knew tight ductwork was essential. After several failed attempts at traditional manual sealing, contractors recommended a new internal approach to duct sealing. To prove success, painstaking measurements were taken before and after the work was done.
Engineered Systems magazine’s March 2019 issue examines the innovations offered by manufacturers at the 2019 AHR Expo and engineers at the ASHRAE Winter Conference, explores the difference between direct drive and belt drive fans in institutional applications, compares and contrasts the prescriptive and performance paths for boiler compliance, and much more.
