ARCHITECTURAL ENCLOSURESRittling...Custom-Building Innovative Hydronic Systems For Commerce, Industry and Institutions Since 1946

Rittling long ago coined the phrase “Reinventing Finned Tube” to describe its commitment to design innovation... and its unlimited custom engineering capability. For decades, Rittling’s constantly-expanding inventory... and proven ability to control costs without compromising the highest quality standards in manufacturing... havemade the name synonymous with image, performance, reliability, price, delivery and service.

Rittling’s diversity and flexibility have freed architects from the constraints of designing around limited catalog selections of standard elements and enclosure configurations. Today Rittling engineers can draw on, or modify, any of 60 different hydronic heating elements... and 97 standard enclosure models... to build any system an architect can draw to tolerances of less than .015 inch... at an exceptionally competitive cost.

For the architects of the future, Rittling will continue to advance finned tube technology in still more new directions... and develop ever more efficient, cost-effective hydronic heat transfer systems.

Fifty years of quality, innovation and service... and we’re just getting warmed up.

To complement contemporary architectural and interior design, models in these series feature enclosures with clean-cut, unobtrusive linear profiles of classic simplicity and strong horizontal lines. The linear effect is further enhanced by flush, “hairline-crack” joints and completely concealed mounting hardware.

These sturdy, high-output enclosures are available in over 16 standard models, with fronts and tops of 14-, 16-, or 18-gauge furniture quality rolled steel. The air outlet is a handsome and rugged extruded aluminum grille that extends the full length of the cover. All models may be modified to suit any hot water or steam heating application, and ordered with any of Rittling’s 42 hydronic heating elements.

THE EFFECTS OF WATER VELOCITY ON FINNED TUBE OUTPUT

TheInstituteofBoilerandRadiatorManufacturerssponsoredatestprogramat theUniversityofIllinois to determine the effect of water velocity on heat output of various sizes of finned tubed element.

The results of this test show that when the water velocity falls below 0.4 f.p.s., the flow changes from turbulent to streamline. With systems designed at water velocities below this point the output cannot be accurately predicted so should always be avoided.

Figure2showsratingfactorsthatcanbeutilizedwhenthewatervelocityfalls below 3 f.p.s.

Itisrecommendedwhendesigninglow-loadsystemsthatthewatervelocitybe a key factor inelementselection.Figure3canbeusedtoensurethatthewater velocity is above the critical level with various tube sizes.

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 free architects from the constraints of hydronic-heating conventions. We can, for instance, customize enclosures to any dimensions in stainless, textured embossed steel... or aluminum, for installation anywhere: in ceilings... walls... or trenches. We’ll angle finned tube systems to match the slope of a floor. We’ll fabricate all copper heating elements and other specialty outlet grilles, 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.
