Benefits
Zehnder Rittling’s reputation for leadership in commercial heating systems design and fabrication thrives on a demonstrated ability to modify or adapt components from our vast standard inventory and to break new ground with innovative applications.
Our ingenuity and expertise allow architects and engineers the ability to break free from the constraints of hydronic heating conventions. We can, for instance, customize enclosures to any dimensions, in stainless, textured embossed steel. This works for installation anywhere: in ceilings, walls, or trenches. We’ll angle finned-tube systems to match the slope of a floor or the curve of a room. We’ll fabricate all copper heating elements or pipe enclosures, without grilles. Challenge us and we’ll build it!
If you have a special application you would like us to evaluate, please call to arrange a consultation with a Zehnder Rittling expert.

- 27 aluminum-finned, copper tube
- 6 different tubes, 5 types of fins, 3 options for fin spacing

Functionality
Zehnder Rittling has specialized in the design and manufacture of finned tube heating equipment since 1946, giving the market an unmatched selection for versatility of design configuration. All Finned Tube models use permanently bonded fins to optimize rapid, constant, high heat transfer.
Zehnder Rittling’s wide range of Enclosures feature sheet metal enclosures, surrounding commercial-grade finned tube element. Dense cool room air around the perimeter drops to the floor level, where by natural convection, it is brought across the heat transfer device, warmed and then flows towards the ceiling. These units are used for overcoming perimeter heat losses.
- Rittling Commercial Finned Tube can be installed bare or with any Rittling enclosure using our cradle-type expansion brackets
- The L-shaped enclosure brackets support both the enclosure and element. Second row brackets are used for bare tube applications, as well as installation of two and three rows
- Enclosures 20 inches high accommodate one or two rows of finned tube; those 24 inches high accommodate one, two or three rows of finned tube
- Dampers are available in most models for airflow control
- Return line supports are available to support different supply and return layouts
