COMMERCIAL HYDRONIC PRODUCTS A MESTEK COMPANY Convectors STEAM AND HOT WATER RADIATION CC-1

Sterling Convectors are engineered for both forced hot water and two-pipe steam heating system installation with heating elements of lightweight non-ferrous construction. They are available in (7) basic types to meet a wide range of heating applications in institutional buildings, hospitals, hotels, office buildings, schools, apartments and other structures. A variety of cabinet enclosure styles permits the selection of an attractive and functional installation to blend with any building interior modern or traditional. INSTALLED IN End Pocket Designed for maximum flexibility of installation arrangement, Sterling Convectors are available in free-standing, semi-recessed, wall hung and fully recessed models. Enclosures are formed from heavy-gauge steel, and finished in prime coat for complete protection against corrosion during shipment and providing a base for final finish to meet architectural requirements after installation. All Sterling commercial hydronic convectors are made from recycled materials. Recycled material contents can be obtained from your local Sterling representative or by viewing the www. sterlingheat.com website. Sterling is a participating member of USGBC-LEEDS. 3 1 5 2 Access Door Locations End Pockets End pockets may be provided at each or either end of Sterling institutional convectors to protect and conceal valves, traps and piping. A left-hand end pocket is illustrated. The liner is extended and a baffle welded to the back of the liner. The cabinet front is extended and grille is offset in length to line up with heating element. Length of end pocket is determined by using a standard element. Specify right or left hand. Available in " increments only. One end pocket only on " long units. No end pockets available on SR-A or RF-A " units. Note: Fronts and liners increase in length but the coil length remains the same. Access Doors Access Doors ( 1/" square) may be provided in the front panel of the convectors for inspection or operation of valves, traps, or air vents. These doors are hinged on top. Concealed 1/ turn locking device is provided with an Allen-head operator. Access doors are available in the standard locations illustrated. For units 2" or less in height, not all positions are available, consult factory. See table 5 on page 1 for derating factors. Heating Elements Heating elements are available in three nominal depths - " with 2-tube element, " with 3-tube element, " with -tube element. Fins of.010" aluminum have integral 2 collars to assure uniform spacing. Tubes are mechanically expanded into collars to permit maximum heat transfer. Both headers are cast brass with single - 3/" NPT tappings. A dual top and bottom 3/" tapped header is available. This option allows for supply and return piping to come from the top or bottom. Combined with the standard single header, piping direction is no longer a problem. Heating element assembly is protected by formed shield plates front and back running the entire length of element, and supported in enclosure by a welded bracket to eliminate strain on piping or element.

Tamper-Resistant Fasteners Our Convectors are provided with friction fit slip joiners. Hex Head Locks, to fasten fronts securely may be provided on special applications. Concealed Fasteners are available with Hex-head operator. Head of operator recessed 1/" inside cabinet. Fastener engages keeper, spot welded to inside of liner. Damper The assembly consists of a triple lead screw and a heavy gauge damper blade, flanged top and bottom for additional rigidity, that covers the entire louvered area of the enclosure. Damper assemblies are available with either a knob operator or a tamper resistant operator which is simply operated with a hex key. The later is particularly valuable in school or institutional work where only supervisory operation is desired. Institutional convectors are specially constructed to satisfy the requirements of strength and safety demanded by institutional building application. Heavy Gauge Steel To withstand the abuse often received on this type of application, institutional convectors are available in heavy gauge steel upon specific request. (Front and back available in, 1 and 1-gauge) Non-Standard Sizes Sizes other than standard can be provided for institutional buildings. Please consult factory with requirements. Perforated Outlet and/or Inlet Consult factory for unit styles offered with 1-gauge perforated front panels. ENCLOSURES Standard Fastener for Recessed Units Institutional Damper Operator Knob Operated Damper Operator Dual Inlet Header Allows piping from either top or bottom. Insulation 1/2" thick fiber-glass insulation is available on convector backs, or sides and tops for special application. (Top does not apply to sloping models) Special Finish All our Convectors are thoroughly cleaned after fabrication and provided with a high quality baked enamel prime coat paint. As an option, cabinet may be finished in one of the standard Convector colors also in baked enamel. Features of enclosure construction are shown below. Note that the element support provides a simple and inexpensive means of leveling the heating element or giving it an appropriate pitch for steam installation. Enclosures are formed steel with front of -gauge, back and sides of -gauge thickness. Enclosure fronts are separate and fastened by friction fit slip joiners at sides of the front piece. Back, top and sides are an integral welded structure in all models, except wall hung slope top model, which has top integral with front.

REF: BTU = GPM x 500 x TD GPM = (BTU 500) TD TD = (BTU 500) GPM CORRECTIONS WHEN USING GLYCOL SOLUTION IN SYSTEM Propylene Glycol 1.

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 13 fall below those shown in Table 9 for 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 12, F water temperature drop 170 F AWT, 5 F EAT Unit FSA-, "deep, " long BTU = 2335 This capacity rating is less than the MBH (3.000) shown in Table 9 for a F TD and the minimum flow rate of.30 GPM. Applying the following formula to the example above, we may determine the GPM required for a F TD at 2335 BTU. GPM = 2335 BTU GPM =.23 500 x TD Again, this GPM is too low to maintain turbulent flow within the element tubes. Therefore, use Min. GPM of.30 per Table 9. The water temperature drop which may be expected when using the Min. GPM can be determined using the following formula: TD = 2335 BTU 500 x.30 TD = 15. F 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 0 F. i.e. 0-15. =172.2 F AWT 2 Then, the new MBH rating may be determined by interpolation between the ratings shown on page 12 for the unit at 170 F AWT and 0 F AWT. In the above example, the new rating would be 215 BTU which would be very close to the actual performance without resorting to futher iterations. 15
