The BAC Expo highlights BAC’s heat-rejection technologies for HVAC applications and its liquid cooling solutions for data centers, allowing engineers, contractors, and owners to see the equipment in real-world configurations.
Installed in 1981, an HDPE cooling tower at Radio Frequency Company has operated continuously for over 40 years – far surpassing the typical lifespan of metal models.
Cooling tower spillover during chiller rotation shows how thoughtful programming, sequence tweaks, and field fixes can tackle system instability in both winter and summer conditions
HVAC systems experience their most challenging moments during operational transitions – when systems first enable, modes shift, or equipment rotates or stages to meet demand. These brief windows often reveal instability that routine operation may hide.
The project also highlights how advances in cooling technology and smarter system design can help manufacturers adapt to extreme process demands while streamlining installation and maintenance.
Legionnaires' disease is caused by the Legionella bacteria, which thrives in warm-water environments and is typically spread through the inhalation of aerosolized water droplets, such as mist from cooling towers, hot tubs, and decorative fountains.
Photos from the project show the new stackable chiller modules, expanded piping, buffer tank, and rooftop fluid coolers – all key components of the library’s advanced, water-saving HVAC retrofit.
When it comes to cooling system maintenance, the smallest choices can ripple into major consequences. Using parts designed for your specific equipment isn’t just a matter of preference — it’s a question of dependable performance and long-term savings.
Baptist Health Medical Center in Little Rock, Arkansas, replaces its aging cooling towers —
overhauling its entire mechanical system with advanced, low-maintenance technology.
Bill McQuade, Vice President for Regulatory Affairs and Global Sustainability at Baltimore Aircoil Company (BAC) and ASHRAE's incoming President-Elect, discusses how innovative cooling technologies are reshaping the future of sustainable building operations.
