Reznor officials report that its new Model SHH is the first commercial air-handling unit that features up to 92 percent fuel efficiency. The company claims that other conventional units could consume up to 15 percent more fuel for the same amount of heat. The Reznor Model SHH features the TCORE3 heat exchanger, the latest generation in a series of 90 percent-plus efficient heaters first introduced 20 years ago. Reznor says that benefits of the Model SHH include fuel efficiency, low emissions, reduced carbon footprints and low environmental impacts.
