A rugged mechanical fin-tube bond helps assure durability and long life. Die-formed aluminum fins are mechanically bonded to copper tubes. The tubes are also mechanically bonded to brass headers with the ends rolled back in a boiler tube style. Features and Benefits Durable Heating Elements 3-Position Hanger Vent Plug Only the brass headers rest on end bracket tabs of the support assembly. The element assembly floats freely during expansion and contraction, relieving the fin-tube portion of any strain. Support assembly expansion and contraction is absorbed by vertical brackets. There is no direct contact with the cabinet and end panels allowing maximum heat transfer to be achieved. 6 Positive Temperature Control An efficient damper is mounted on the element. The damper reduces unit capacity by 70 percent. The bead chain control system is jam-resistant. The control knob is mounted on the outlet grille.
Selection Procedure Hot Water Systems The rating of convectors in a hot water system is determined by average water temperature, temperature drop and inlet air temperature. Tables PD-7 through PD- 30 contain <strong>Trane</strong> convector ratings at 10, 20 and 30 F temperature drops and average water temperatures with 65 F entering air temperature. Steam Systems The rating of convectors in a steam system is determined by steam pressure and entering air temperature. Tables SP-1 through SP-4 contain <strong>Trane</strong> convector ratings with 1 psi steam and 65 F entering air temperature. Refer to Table PAF-2 for steam correction factors above onepound gauge. All ratings are in accordance with provisions of Commercial Standard CS 140-47. Ratings at Other Than Standard Conditions Use the following formula to determine output: C s = [ t s - t i 215-65 1.5 ] H = H x C O s s This is an exponent to the 1.5 power per IBR correction factors where C s = Correction factor t s = Steam temperature at operating conditions – F t i = Inlet air temperature at operating conditions – F H s = Standard catalog rating H O = Rating at operating conditions 7 Heating Effect Convector capacity ratings in this catalog represent condensation capacity increased by the percentages shown in Table PAF-3. This is in accordance with provisions of Commercial Standard CS 140-47. Rating of Units Longer and Higher Than Standard Rating of units longer than standard is determined by extrapolating from published rating tables. Ratings for units above 38-inches high are about five percent higher than the highest standard convector. Effect of Grilles on Ratings Shown in Table PAF-4. Two Elements in a Cabinet The rating of a standard convector is not materially increased by placing two elements, one above the other, in a cabinet. Conversion Factors Btu to EDR Table PAF-5 permits selection of convectors for hot water systems directly from steam rating tables after heat losses have been calculated in Btu. For example, assume a forced hot water system with room heat loss of 8,000 Btu. The average water temperature is 190 F at 20 F temperature drop. From Table PAF-5 the Btu per square foot of steam capacity is 160. Dividing 8,000 by 160 equals 50 square feet EDR. The required convector can then be selected from the steam rating table.
