Steel Convector Elements

WENIG manufactures a complete line of high efficiency Copper Fin Tube Elements for hot water heat systems. Each aluminum fin has a die formed collar for even spacing and complete contact the entire length of the copper tube. The tubes are mechanically expanded and rolled into the headers. The headers are made of the finest cast brass. Steel side plates protect the fins and add to the rigidity of the elements. All elements have been carefully engineered to provide maximum heat transfer and years of care free service. Elements are tapped: 1-1/4” supply, 3/4” vent - One pipe steam
3/4” supply, 3/4” return - Two pipe steam
3/4” x 3/4” - End tappings

CS 140-47 The ratings of these convectors have been determined in conformance with Commercial Standard CS 140-47, as developed cooperatively by the trade and The National Bureau of Standards, US Department of Commerce and The Faid Ratings have been proved by the Convector Rating Committee.

Heating Effect These ratings represent the condensation capacity to which have been added. The following percentages in accordance with the provisions of CS 140-47.
Cabinet Height 18”/20”/24”
Percentage Increase 15%/14%/10%

Steel Convector Elements Specifications
Steel Heating Elements shall be constructed of 3/4” O.D. steel tubes, steel fins, cast iron headers and steel side plates. Holes in fins shall have die-formed flanged collars for neatly and efficiently spacing fins on tubes. Tubes shall be mechanically expanded into fin collars to provide metal contact between tubes and extended surfaces and shall be secured to headers by means of silver solder to provide permanent assurance against leakage and loosening of tubes. Heating element shall be leak tested under water with 150 p.s.i. air pressure.
