The housing panels are die formed from mill galvanized steel and insulated with 1" - 3/4 pound density mat faced fiberglass insulation. All fan sections have hinged and latched access doors. Unit below has fan and coil section. Heatcraft puts the motor inside the fan section cabinet. It is mounted on a heavy gauge steel slide rail base. There are several advantages with internal motor location. It eliminates the need for a bulky belt guard. Another advantage is that Heatcraft balances the factory mounted motor and drive components, which can eliminate additional balancing at start-up. Fans All units have single, double width, double inlet fan wheels for quiet performance and low energy consumption. Single wheels eliminate the problem of unequal loading which is characteristic of units with multiple wheels. Also, the expense of a “pants” type duct connection is avoided. Sizes 03 through 41 units have forward curved and size 50 through size 75 units have airfoil fan as standard. Forward Curved Fans Coil sections cover a wide range of heating and cooling requirements. Side, top and bottom panels are 16 gauge mill galvanized steel. All coil sections accommodate either small or large face area coils. The HCS coil section will hold 15 1/2" of coils and spacers. The HCS section covers most applications. Use the HCL coil section if the coil or access space is more than 15 1/2". (See page 38 for maximum per model.) Air Foil Fans Bearings Unit sizes 03 through 12 have lifetime lubricated fan bearings as standard. Unit sizes 03 through 12 with optional medium pressure fan have pillow block bearings rigidly supported on a heavy steel frame. Unit sizes 14 through 75 have pillow block bearing rigidly supported on a heavy steel frame as standard. The bearings are self aligning and are selected for an average service life in excess of 200,000 hours. There are extended lube lines and grease fittings on the drive side of all units that have pillow block bearings. The bearings on these models can be lubricated without opening the blower section access door. Maximum operating temperature is 140°F. Fan Shaft The fan shaft is solid polished steel, and keyed for both fan and drive. It is designed so that critical speed is at least 1.25 times the maximum operating speed. 4 Coil Section Cooling coil sections have a drain pan with double wall construction. Insulation is sandwiched between the outer panel and the inner drain pan. The pans are heavy gauge mill galvanized steel. Heatcraft welds the corners of the drain pans and puts drain connections on both sides of the coil section for field convenience. The coils sit in an upright position inside the coil section. The air flows horizontally through the coils. Larger models (sizes 50 through 75) have cooling coils stacked two high.These larger models come with an intermediate drain pan, so that condensate from the upper coil does not flow over the lower coil. Coils come in either small or large sizes (pages 42-43). A large face area coil fills the total face area of the coil section. The coil section’s total air volume passes through the large coil. A small coil is shorter in height and does not fill the total face height of the coil section. Air may bypass above the coil through balance dampers or internal face and bypass dampers. With either combination, it is possible to adjust and control the amount of air passing through the small size coil. Chilled water and direct expansion coil face velocities over 550 FPM should be avoided--WATER CARRYOVER. If desired, a blank off plate above the small coil can force total coil section air volume through the small coil. Air Handler Coils There are a wide variety of coil types to meet the load requirements of conditioned spaces. Heatcraft’s four coil types are: water, direct expansion, heat reclaim and steam coils. All standard coils have copper tubes and aluminum fins and a heavy gauge mill galvanized steel casing. Staggered tube designs increase air turbulence and improve coil performance. The plate type, die formed, corrugated fin design provides optimum strength. The fin design also enhances air turbulence for peak performance. Each fin has die formed, self-spacing fin collars which completely surround the tubes. Heatcraft mechanically expands the tubes into the fins to provide maximum heat transfer. Fin spacing selections of six to fourteen fins per inch insure that an optimum coil is offered to meet specific design needs. Water Coils Water Coils Direct Expansion Coils A wide range of choices leads to the best coil selection for each particular job. Select water cooling coils from 4, 5, 6, or 8 row coil depth options. Select water heating coils from 1, 2, or 3 row coil depth options. All water coils offer five fin densities (6, 8, 10, 12, or 14 FPI). Specify either 1/2" (Type A) or 5/8" (Type 5) tube diameters. Heatcraft optimizes circuit design from the header into the coil and delivers high internal heat transfer coefficients for each application’s conditions. This is done without resorting to internal devices which increase pressure drop or restrict draining. All circuit designs avoid trapped circuits, so the coil is drainable. There are vent and drain connections on both supply and return headers on coils of 3 or more rows. All coil connections terminate outside the air handler coil section cabinet. Design working pressure is 250 PSIG. Design fluid temperature for heating coils is 300°F. Select direct expansion coils from 3, 4, 5, 6, or 8 row coil depth options. All direct expansion coils offer five fin densities (6, 8, 10, 12, or 14 FPI). Specify either 1/2" (Type A) or 5/8" (Type 5) tube diameters. Each coil has a brass, sweat connection type distributor and copper suction header. Distributor leads of equal length work for equal refrigerant distribution to all the circuits. Working with Heatcraft software or your representative, select from a among variety of circuit designs. Heatcraft has an optimum design to deliver the proper refrigerant pressure drop for your conditions. Specify multiple distributors for face split or row split control of the coil. Direct Expansion Coils Heat Reclaim Coils Condenser Heat Reclaim Coils Refrigerant Heat Reclaim (RHR) coils with multiple circuits handle applications where a number of refrigeration compressors are connected to a single coil. Each circuit has heavy wall copper, sweat type, hot gas inlet and liquid or cooled gas outlet connections. Heatcraft's custom coil circuiting maintains an internal coil pressure drop below 5 PSIG for each system. Depending upon job requirements select 1/2" (Type A) or 5/8" (Type 5) tube coils, select one of five fin densities (6, 8, 10, 12, and 14 FPI), and select from coil row depths of 2, 3, 4, 5, 6, an 8 rows. Steam Coils Nonfreeze Steam (NFS) coils have internal steam distributing tubes which are directionally lanced for high performance and good condensate removal. The coils are also pitched in the coil casing. The design working pressure and temperature of standard copper tube coils are 150 PSIG and 366ºF. respectively. Depending upon job requirements, select the 5/8" (Type 5) tube diameter coil at an optimum fin spacing and a one or two row coil depth for air handler model sizes 03 through 50. For models 65 and 75, select the 1" (Type 8) tube diameter coil with one row at an optimum fin spacing. Steam Coils 5 Accessories- Electric Heat Electric heaters are UL listed for duct installation. The UL label applies to the heater only, not the complete air handler. Heaters are furnished as a separate section and are available with insulated or uninsulated casings. Controls such as contactors, fuses, etc., may be factory installed and wired in the heater section end panel provided the number of control steps is not excessive. Remote control panels are also available. Construction & Dimensions Y Unit Size 03 06 08 10 12 14 18 20 26 34 41 50 65 75 Heater Dimensions (In.)

How many fuse blocks required? is: 4.0 STEPS is: 4.0 FUSE BLOCKS °F. 153 38.2 Order the 153 KW to get the 27 degree rise. Throw out the 3 steps (figured at 10°F. rise in part B), because it is smaller than the two values figured per contactor size (parts D & E). Decide whether you want high amps or low amps contactors, if you want low amps contactors, round the 7.7 to 8 and order 8 of the low amps contactors (you now have a possible 8 steps of control). If four steps of control are satisfactory, order the high amps contactors. In either case, the application requires four fuse blocks (part E). Notes: 1. You must order the split shipment of the fan and coil sections to get electric heat on unit size 03 through unit size 18. 2. All electric heat controls are built into the heater control box. 3. Specify two pole break contactors or three pole break contactors. Two pole contactors only de-energize, while three pole contactors disconnect. 4. Be aware of requirements for heater circuits rated more than 48 amps. According to N.E.C. Code and U.L. you must subdivide the heater elements of such circuits. N.E.C. Code requires that the sub-circuit fuses be furnished by the heater manufacturer. Commonly Used Control Systems: A. For small loads (up to 20 KW),consider a multi-stage thermostat. B. For medium loads (up to 200 KW), consider a modulating thermostat that operates a step controller. C. For fine control of large loads (above 75 KW), consider a combination step control and SCR vernier system. This scheme has 80% of heater capacity controlled by conventional step controller, with the other 20% on a solid state SCR controller. D. For 100% proportional control of any size, consider a total SCR control. E. Heatcraft does not supply : multi-stage thermostats modulating thermostats But you will want to order contactors and fuse blocks from Heatcraft that are appropriate for for the control scheme specified in the field. 7 Accessories Mix Box Sections Flat Filter Sections Flat filter sections are space saving and economical. Choose either two inch or four inch filters. The two inch filters can be the throwaway, the 35% pleated, or the high velocity cleanable type. Four inch filters are 35% pleated, they have more filter surface than two inch filters. Four inch filters impose less static on air flow and do not need to changed as often as two inch filters. The filters slide into metal channels and are removable from either side of the section. The Mixbox is an entering air section. Typically, themixbox accepts air from two sources. Many system designers economize performance by varying the two air flows to deliver conditioned air with minimum energy consumption. Mixbox sections are constructed with heavy gauge mill galvanized steel. Select from three inlet opening locations: the air can enter through openings at the top, at the back, or at the bottom of the section. Order the mixbox with or without dampers. The section with dampers has parallel blades at each opening and an interconnecting linkage between the openings. The damper rods rotate in frictionless sleeve bearings, and the drive rod extends from both sides of the section for either left or right hand drive. Flat Filter Section High Capacity Filter Sections Designed for high air volume applications. Filters are arranged in a V or W pattern for the greatest surface possible which provides extended filter life and reduced resistance to air flow. This means less fan horsepower. The sections have access doors on each side to ease filter change. Mixbox Face And Bypass Dampers High capacity Filter Section High Efficiency Filter Sections For damper applications, choose either the internal face and bypass section or the external face and bypass section. If used with a large coil the damper section must be the external face and bypass damper type. When used with a small coil, select the internal face and bypass damper section. The damper sections have balanced opposed blades with interconnecting linkage. The blades positively lock to the damper shafts. The shafts rotate freely in frictionless sleeve bearings. High Efficiency Filter Sections Select 22", 28", or 44" bag filter sections. Choose medium or high efficiency bag or cartridge filters for this section. See pages 9, 29, 42, and 43. Sections are complete with prefilter and bag filter tracks. The sections have an extruded aluminum final filter track with a reinforced nylon pile seal. The postive seal forces the air flow through the high efficiency final filter.

Air handler selections vary with each application. Use the index below to find Heatcraft Products air handler performance tables for: • Standard comfort cooling (either direct expansion or chilled water) 2. • Heating (either steam or hot water, either make up air or return air) • Supermarket air conditioning (direct expansion refrigerant) • Heat reclaim (coil performance, refrigerant condenser, typically supermarket) The air handler performance tables give ARI ratings for the specific applications, conditions and coils listed. All performance tables (except reclaim) rate: 10 FPI coils at 500 FPM coil air velocity. To select air handlers for other applications, conditions, or components: • Call your representative. With your representative, you can have specific computer selected coils rated for your job conditions. • Use tables on pages 21 to 23 for estimates of coil performance at various conditions. 3. See page 12, step 5 to calculate total static pressure. Consult fan tables, pages 24 to 29 and select fan motor. 4. Heatcraft builds each air handler to your components specifications. Please specify the following as needed with your order: • CFM • External or total static pressure • Motor HP, motor type, motor voltage, motor location (left hand or right hand) • Describe coils or specify with Heatcraft Products model numbers. Coil description can include: Rows, FPI, refrigerant, design capacity (BTUH), Number of circuits, coil location inside air handler (preheat, reheat, etc.) Location of coil connections (left hand or right hand) • Filter sections and filter types • Vibration isolators 5.
