FEATURES AND BENEFITS Low Operating Temperatures & Premium Performance The Sterling High Capacity Finned-Tube is intended specifically for the use with low temperature water operating condensing boilers and ground source heat pumps. Allows For Maximum Boiler Operating Efficiencies Most Efficient & Comfortable Heating Option Available Greater Comfort with Room-by-Room Temperature Control When utilizing the many advanced control devices available, each room allows for comfort settings for the occupants based on personal preference. Clean and Healthy Heat from the natural convective action is distributed evenly along the exterior walls of the room, warming the wall while replacing the cold with warmth. When using hydronic heating systems, the building s ventilation system can be reduced in size, allowing additional budget to increase the quality of the indoor air quality system. This will provide cleaner and better air quality, and fewer airborne germs circulated throughout the building. Design Flexibility Future zoning or circuit layout changes are easily done and cost less than changing out expensive duct work. Custom Paint Color Matching Sterling s state-of-the-art powder paint system allows for the matching of custom colors and includes the availability of RAL color offerings. Multiple Enclosure Material & Gauge Options Cold Rolled Steel is standard. Aluminum and Stainless Steel are available options. Choose from 8, 6, & 4 gauge material thickness. Made in the U.S.A. All of the Sterling High Capacity products are proudly made in the United States utilizing domestically produced raw materials.

Capacity and Selection Data SELECTION. Determine the conditions of the system. (If hot water, the average temperature, temp. drop, etc.) 2. Determine the MBH capacity of the unit as required for each location as shown on plans or based on heat loss calculations. 3. Refer to the hot water capacity tables on page thru 23 which list capacities at the conditions for the job, for the model convector required. 4. Locate in table the required capacity and read convector size from columns showing Depth, Length, Height. 5. For rating below 60 F use correction factors from Table 3 for desired AWT and multiply times 25 F rating.

MBH 5 EXAMPLE: Temperature drop 0 F Factor from formula.0 5 x.0 = 3.0 GPM Where systems are designed for low flow rates (velocity) it has been determined by ASHRAE and the Hydronics Institute (I.B.R.) that a minimum flow rate of.25 F.P.S. should be observed. No formal test information is available for performance below the.25 F.P.S. at this point in time.

Note: Table 9 shows MBH which result at specific water temperature drops and minimum water flow rates which are required to maintain turbulent flow within element tubes. If the MBH output rating capacities shown on pages to 23 fall below those shown in Table 9 for the minimum flow rates, this indicates that the GPM required at a F water temperature drop is less than the minimum GPM required to maintain turbulent flow. Example: From page, - F water temperature drop -70 F AWT, 65 F EA -Unit: FSA-8, 8 deep, long -MBH = 2.6 (Rated capacity) This capacity rating is less than the MBH (2.8) shown in Table 9 for a F TD and the minimum flow rate of 0.28 GPM. Applying the following formula to the example above, we may determine the GPM required for a F TD at 2.6 MBH. 2.6 MBH GPM = ---------------- GPM = 0. x TD Again, this GPM is too low to maintain turbulent flow within the element tubes. Therefore, use Min. GPM of 0.28 per Table 9. The water temperature drop which may be expected when using the Min. GPM can be determined using the following formula: 2.6 MBH TD = ----------------- TD = 8.57 F x 0.28 Note: By using the higher flow rate, a lower water temperature drop will be experienced. Because of this, the average water temperature will be higher and result in a somewhat higher output capacity. For many installations, the use of the minimum GPM from Table 9 will be satisfactory, without further consideration. However, if required, a closer approximation may be obtained by dividing by two and subtracting the result from the entering water temperature of 80 F. 8.57 i.e. 80 - (----------) = 70.7 F AWT 2 Then, the new MBH rating may be determined by interpolation between the ratings shown on page 6 for the unit at 70 F AWT and 80 F AWT. In the above example, the new rating would be 2.6 MBH which would be very close to the actual performance without resorting to further iterations.

VENT PLUG NOTE: When ordering convectors with end pockets always refer to the standard unit length. The overall physical length will increase by 4 for each end pocket. The coil length will remain the standard size. Coil fins are 2 /2 high by width shown above and are mechanically bonded to copper tube at 6 fins per inch. 3-POSITION HANGER WELDED TO LINER CAT-45A Non-ferrous convector heating elements consist of aluminum fins specially collared and mechanically bonded to 3/8 diameter copper tubes as the primary radiating surface. The tubes are joined at each end by cast brass headers for connection to the system risers. One header is provided with /4 NPT tapping for venting, the other header is supplied with a /4 NPT galvanized plug. All elements have steel side plates for appearance and strength. Standard heating element is supplied with two single 3/4 NPT headers. An optional dual inlet header is available. This allows for piping to come in from the top or bottom of element. Specify DH header one end when required.
