HVAC products manufacturer Field Controls LLC has purchased Ultra-Sun Technologies of Corona, Calif. Terms were not disclosed.

Ultra-Sun is a maker of indoor air quality products for cleaning air in homes, commercial buildings, offices and laboratories. Its flagship product uses ultraviolet-C spectrum light to turn on a titanium “honeycomb” that uses photo-catalytic oxidation to reduce volatile organic compounds, smoke and odors.

Ultra-Sun founder and CEO Robin Scott said he was excited to become part of Field Controls. “Field Controls has the sales team and distribution network to take our products to a new level,” Scott said. “This is a great day for Ultra-Sun.”

Patrick Holleran, president of Field Controls, said Ultra-Sun is known for its research and development work — something Field Controls plans to take advantage of.

“Ultra-Sun is developing truly innovative IAQ solutions that will further enhance our Healthy Home System offerings,” he added.
