Zehnder Rittling

What Zehnder Rittling does

Zehnder Rittling (legally Hydro-Air Components Inc.) is a Buffalo, New York-based manufacturer of commercial hydronic heating, radiant ceiling heating/cooling, and chilled beam HVAC products. The company traces its operating heritage to the Rittling Corporation, founded by Charles Rittling in 1946, and was acquired by Hydro-Air Components in 1979 before being acquired by Swiss group Zehnder Group in 2006, after which the Zehnder Rittling brand was adopted. Its product portfolio spans enclosures, finned tube elements, cabinet convectors, cabinet unit heaters, storage cabinets, panel radiators, and induction units under hydronic heating; Carboline, Alumline, Linear, and Zip ceiling panels under radiant heating/cooling; and chilled and induction beams (including the NuClimate product line). Core technology is water-based thermal transfer, anchored by foundational patents from 1930 (steel tube welded radiator design) and 1953 (twin tube residential baseboard elements), supplemented by in-house CAD engineering for custom-built solutions.

The company sells project-specified equipment to architects, engineers, and contractors on commercial, institutional, and industrial construction projects across North America (U.S. and Canada). Go-to-market is conducted through an independent manufacturer representative network, supported by a Rep Finder tool, the E-zselect.com technical specification platform, and direct sales contact. Pricing is quote-based with project-specific terms (FOB shipment, payment terms per purchase order); no public list pricing exists. Customer concentration is diversified across higher education, healthcare, technology, and nonprofit/professional services segments, with named installations including University of Georgia, American University, Arizona State University, Dartmouth Hitchcock Medical Pavilion, Intuit, and Anne Arundel Community College. Marketing includes AHR Expo participation, a technical literature library, and presence on Facebook, YouTube, and LinkedIn.

As a wholly-owned subsidiary of Zehnder Group (Switzerland, ~3,000 employees globally), Zehnder Rittling operates alongside sister brands Runtal, NuClimate, Zehnder America, Lifebreath, and Zehnder Clean Air Solutions. The company is led by CEO Scott Pallotta, appointed from McQuay International where he served as General Manager of Applied Terminal products. Revenue, funding, and detailed headcount are not publicly disclosed; the company's competitive positioning rests on 70+ years of specification-driven brand equity, patented hydronic technology, custom CAD engineering, and the distribution muscle of its manufacturer representative network.
