Standard Unit Features
Basic Ca
Basic Cabinet
Motor Mount
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.
Consists of a fan section and a coil section with double wall drain
pan. 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.
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.
Coil Section
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.)
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.
Forward
Curved Fans
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.
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.
Fan Shaft
If desired, a blank off plate above the small coil can force total coil
section air volume through the small coil.
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.

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
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.
Water
Coils
Direct Expansion Coils
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
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.
Condenser
Heat
Reclaim
Coils
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.

°F. 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).
Commonly Used Control Systems:
Notes:
A.
For small loads (up to 20 KW),consider a
multi-stage thermostat.
For medium loads (up to 200 KW), consider a
modulating thermostat that operates a step
controller.
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.
For 100% proportional control of any size,
consider a total SCR control.
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.
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.
B.
2.
3.
All electric heat controls are built into the heater
control box.
C.
Specify two pole break contactors or three pole
break contactors. Two pole contactors only
de-energize, while three pole contactors
disconnect.
D.
E.
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.

Accessories
Mix Box Sections
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 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.
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
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

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.

4.
See page 12, step 5 to calculate total static pressure. Consult fan tables, pages 24 to 29 and
select fan motor.
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

Selection Example
Air Handler Selection Conditions:
“I want a ceiling mounted air handler that gives 35 tons of cooling and 35 tons of heating. I have 44°F. water for
cooling and I have 200°F. water for heating. My entering air temperatures on the coil are standard, that is 80°F. dry bulb and 67°F. wet
bulb (50% relative humidity) for cooling. For heating, the entering air temperature is 60°F. I will supply duct work,
you should select the motor to handle a half inch of external static pressure. Select the smallest air handler possible and tell me what kind
of CFM, flow rates, fluid pressure drops, and sensible cooling performance your selection will give me. I want a filter too.”
Selection Procedure:
1. Which air handler for cooling performance?
Look at index of air handler performance

A. Change the application’s requirement at application’s TD
to adjusted requirement at 50°F. TD. Use Table 15:
344/0.9 = 382.2 MBH (adjusted)
B. Divide the adjusted MBH by the coil face area:
382.2 / 26.56 = 14.4 MBH (adjusted) per square foot
C. Find the coil air speed:
75.35
74.92
13280 / 26.56 = 500 fpm
D. Select coil rows and fins per inch from Table 16 at coil air
speed and with enough MBH to meet the MBH (adjusted to 50°F. TD) per square foot figured in step B:
Select 3 row 8 fin per inch coil with capacity of 14.56 MBH per square foot at 50°F. TD.
For this application, capacity equals: (14.56 x 26.56 x 0.9) or 348 MBH for size 26 at 45°F. TD.
E. When ordering, please specify refrigerant type and the total heat of rejection for each reclaim circuit.
Or specify the per cent of the total heat of rejection that is reclaimed for each circuit.

^ Average water temperature = (entering water temp + leaving water temp) divided by 2.
** For type 5, at 5 PSIG, if (total MBH divided by 0.961) divided by coil tubes is more than to 50 LB per tube, the condensate loading may be too high. At
higher pressures the condensate loading can be more than 50 LB per tube. Get a computer rating for the application.

Mechanical Specification
Coils
General
Provide water heating, water cooling, steam heating, and direct expansion coils
with ARI certification. All coils shall be of cartridge type, coils removable
from either side of casing. Direct expansion coils are to be aluminum ripple
corrugated plate fins on the staggered copper tubes. Fins shall have belled
collars and shall be bonded to tubes by mechanical expansion. Maximum
working pressure shall be 250 psig at 300°F. Coil shall be submerged in water
for testing. Direct expansion coils shall be provided with pressure-type brass
distributors with solder-type connections. All coils shall have a minimum of___
distributors, charged with dry air. Tubing for coils shall be copper with 1/2 or
5/8 inch outside diameters. Coils shall have suction and discharge connections
on the same end. Heatcraft coil performance data is certified as complying with
ARI Standard 410.
Provide a air handler of sound materials construction and design. Frame mem-
bers, structural bases and all casings parts are fabricated from mill galvanized
steel. The table on page 39 specifies the metal gauge of each component. Ex-
terior panels are to be a minimum of 16 gauge galvanized steel. Access doors
in the fan section provide complete access to motor(s), belts, drive(s) and fan.
Removable casing panels in the coil section permit removal of coil from either
side. Fan housings extend from the fan section panel for duct connections.
Air Conditioning Models - VCS, HCS, HCL
Provide a air conditioning air handler to meet cooling and condensate require-
ments. The air handler shall have standard insulation in both the fan and cool-
ing coil sections with a drain pan as described below.
Filter Sections
Flat - Provide the air handler with an accessible flat filter section. Flat filter
sections for 2 and 4 inch filters are available on all sizes. Access doors are
furnished on both sides.
Cooling Coil Sections
Provide a air handler with a readily accessible and drainable coil section. Coil
sections have removable panels on each side. Drain pan is of double wall con-
struction with insulation sandwiched between the metal pans. Two (2) 1-1/4"
FPT drain connections are supplied. These drain connections are furnished on
each side of the drain pan on all sizes. Drain pans are #16 gauge galvanized
steel. Provide standard insulation for the cooling coil section as described
below.
High Capacity - Provide the air handler with an accessible high capacity filter
section. High capacity filter sections are for 2 inch filters. High capacity filter
sections have one large door on each side.
High Efficiency - Provide the air handler with a high or a medium efficiency
filter section. Units are constructed of 16 gauge galvanized steel. Fully gasket-
ed doors are standard on each side of housing and units are fitted with positive
pressure trip lock latches that assures a tight seal. Both 2 inch prefilter and one
inch final filter tracks are extruded aluminum combined with reinforced nylon
pile seal to create a corrosion resistant seal.
Insulation
Provide the air handler with adequate insulation for air conditioning require-
ments. Standard Insulation is 1"-3/4# (1 inch thick, 3/4 lbs per cubic foot)
fiberglass. Insulation is mat faced to prevent erosion. It meets the NFPA 90
Standard for flame spread and smoke generation.
Economizer Section
Heating And Ventilating Models - HD
Provide the air handler with an economizer with inlets options at the back,
bottom, and top of the section. Economizer damper casing and blades shall be
not less than 16 U.S. gauge galvanized steel. Each blade shall be die-formed,
multi-break and not exceed 49 inches in length. Blades are to be mounted to
a single square one half inch rod, to prevent linkage slip, extending the full
length of the damper casing.
Provide a air handler to meet heating or ventilating (but no cooling) duty
requirements. The standard heating unit includes 1 or 2 row heating sections.
Furnish deeper coil sections for 3, 4, or 6 row coils. Do not insulate the fan or
coil sections on these units.
Fans
Provide a air handler with fan section that meets air flow requirements. All
units have been certified as complying with ARI Standard 430. All units have a
single fan design (either forward curved or airfoil). The fans are statically and
dynamically balanced in fan section before the unit leaves the factory. Fans and
shafts operate well below the first critical speed. Fan bearings are ball bearing
type selected for 200,000 hour average life. Low pressure LF fans - Sizes 03
through 12 have lifetime lubricated, rubber mounted, cartridge bearings. Unit
sizes 14 through 75 have extended lube lines to the outside casing of the air
handler on drive side.
Face and Bypass Section
Dampers are opposed blade type. Shafts rotate in porous bronze bearings.
Access Section
Access sections have two hinged and latched doors, for all unit sizes. Access
sections are not insulated as standard.
