Surpassing the performance and efficiency of other rooftop systems, Sterling HVAC announced the commercialization of the Xcelon system, the first rooftop make-up air unit that combines innovative hydronic condensing boiler technology with advanced air distribution and heat recovery methods, for unparalleled levels of efficiency up to 98 percent.
Conceptualized and developed by Sterling, well-regarded throughout the industry as a leader in HVAC innovation, Xcelon’s unique engineering integrates hydronic technology, a new air distribution system, and an integrated control platform to produce ultra-high efficiencies, making it a truly revolutionary step in make-up air rooftop systems.
Available with a 800 – 1,200 MBH heating capacity, Xcelon utilizes an innovative factory charged, closed loop 35 percent glycol mix for freeze protection with no separate water supply required. It can offer airflow of 4,501 – 10,000 CFM.
Xcelon systems have been in testing in some of the coldest environments in the U.S. and Canada for more than two years, but have not been released until today to ensure the technology was performing as designed. With its unique air handler, heat exchanger and heat recovery system, Xcelon has surpassed expectations and is now ready for commercialization.
