A variety of coil options reduces first cost Four or 6-row cooling coils combine the capacities you need with the most efficient heat transfer surface. For 4-pipe systems, select either of two split-coil options. Coils consist of aluminum fins securely bonded to 1 / 2-in. OD seamless copper tubes. Each fin s aluminum collar ensures accurate control of the fin spacing, while completely covering the tubes to lengthen coil life. All coils also feature manual air vents, with automatic air vent available as an option. Fan wheels are designed to provide low operating costs The forward-curved, centrifugal, double-inlet fans are statically and dynamically balanced at the factory to minimize transmission of vibration to the building structure.

The belt-driven motor (single or three phase) has a variable-pitch pulley which adjusts at the jobsite to accommodate limited ranges of air quantities and pressures. All motors (single and three phase) are UL listed, factory wired, single speed with thermal overload protection and are continuous duty rated. Motors are supplied with permanently lubricated bearings, class-b insulation and are open drip-proof. The motor mount has an adjustable platform for easy belt adjustment. The motor and its mounting are independently isolated from the cabinet and the blower. An adjustable pitch pulley allows CFM balancing to meet system requirements. Motor drive packages are provided with keyed pulleys. Complete factory assembly minimizes on-the-jobsite costs and problems Compact, lightweight units are designed for easy mounting. Knockouts designed to accept 3 / 8-in. threaded rod are provided on the top and bottom of each corner of the unit One-in. duct flanges on discharge and on return are furnished standard. These integral duct flanges cut installation time and labor expense. Durable construction means easy-to-maintain units The 42BH casings are fabricated from heavy-gage galvanized G90 steel, reinforced for maximum rigidity and structural strength. Removable side panels with tool-less camlock latches allow easy access for servicing interior components. One-inch matte surface, fiberglass thermal/acoustical insulation lines the fan coil cabinets to prevent sweating and to muffle sound transmission. The stainless steel, double-sloped condensate drain pan extends under full coil surface to cut maintenance costs. Table of contents Slide-in return-duct collar filter makes it possible to remove and replace the filter without disturbing return air ductwork.

Selection procedure This section provides quick-selection tables for the 42BH. Quick selection tables are based on nominal CFM. Correction factors are provided for other operating conditions as explained in the following quick selection example. For applications outside the range provided in this catalog, please consult the factory. FORMULAS TC = TCb x Ct x Et SC = SCb x Cs x Es Where: Cs = Sensible Air Flow Correction Factor Ct = Total Air Flow Correction Factor Es = Sensible Elevation Correction Factor Et = Total Elevation Correction Factor SC = Sensible Capacity SCb = Base Sensible Capacity from Base Cooling Capacities by GPM charts TC = Total Capacity TCb = Base Total Capacity from Base Cooling Capacities by GPM charts EXAMPLE 1: I Rate unit performance To rate the performance at sea level for an 42BHC-16 unit with a four-row coil at 80 F/67 F EAT, 45 F EWT, 7 GPM water flow, and 1500 CFM: a) Enter the Base Cooling Capacities by GPM, Standard Capacity Units (Four Row) table on 80 F/67 F EAT and 45 F EWT. b) Locate the appropriate row for unit size 16 and 7 GPM. Record the tabulated base performance. TCb = 43.8 MBtuh SCb = 34.9 MBtuh T = 12.5 F c) Divide CFM Actual by CFM Nominal to determine CFM Ratio. CFM Ratio = 1500/1600 =.9375 II Select CFM correction factors Select the CFM correction factors, Ct and Cs, from the Air Flow Correction Factors table. (Interpolation may be required.) Ct =.9625 Cs =.96 Select the elevation correction factors, Et and Es, from the Elevation Correction Factors table. (No correction necessary in this example, unit is at sea level). Et = 1.00 Es = 1.00 III Calculate actual performance. TC = TCb x Ct x Et = 43.8 x.9625 x 1.00 = 42.16 MBtuh SC = SCb x Cs x Es = 34.9 x.96 x 1.00 = 33.50 MBtuh a) Calculate water pressure drop (or refer to the Water Pressure Drop for Cv Factor and Water Flow Rate table on page 16). From the Cv Factor by Coil and Unit Size table on page 15, find the Cv value for unit size 16 with four rows. Cv = 7.2 P = [GPM/(0.658 x Cv)]2 = [7.0/(0.658 x 7.2)]2 = 2.18 feet of H 2O b) For selections other than those listed here, please contact the factory. IV Determine motor and drive To determine motor and drive selection requirements and obtain the CFM for a specific application, the total static pressure (TSP) for that application must be determined. The TSP is the sum of the internal static pressure (ISP) and the external static pressure (ESP) measured in inches of water column. ISP is sum of the static resistance of the components of the unit the cabinet, coil and filter. ESP is the static resistance of the external components of the unit, including, but not limited to, duct work, grilles and additional filtration. For nonducted applications, the ESP is 0 inches. After the TSP has been calculated (see the following example), use the motor horsepower table to determine the actual horsepower (HP) for your Belt Drive unit. Horsepower offerings are limited to 1 / 4, 1 / 3, 1 / 2, 3 /4, 1, 1 1 /2, 2 and 3. The standard selection is the nearest offering above the actual HP shown in the table. Using the TSP of the table, match the unit size with the CFM row to determine the correct motor for your specific application. Drive sheaves and the required belt assembly will be provided to meet your design requirements. Drive sheaves are set at the factory. Calculate the HP and drive selection required to deliver 1500 CFM on a 42BHC-16 unit equipped with a fourrow hydronic cooling coil and a two-inch pleated filter in a ducted application at.38 inches ESP, including duct and grille losses. Using the Component Static Resistance table on page 15, the ISP is calculated as follows: Cabinet 4-row Wet Coil 2-in. Filter ISP ESP TSP.09-in. wg.30-in. wg.12-in. wg.51-in. wg.38-in. wg.89-in. wg 7

Calculating pressure drop: The Cv factor is equal to the flow rate of water in GPM through a piping component when the pressure drop through the component is 1.0 pounds per square inch (psi), or 2.31 ft wg. P (ft wg) = P (psi) x 2.31 Use the Cv factor from the Cv Factor by Coil and Unit Size table to determine the water coil pressure drop. Coil pressure drop (ft wg): P = (GPM 2 /Cv 2 ) x 2.31 or P = [GPM/(0.658 x Cv)] 2 or Refer to the Water Pressure Drop for Cv Factor and Water Flow Rate table. See example on page 7.
