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.

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.

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.

°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:

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.

You must order the split shipment of the fan

and coil sections to get electric heat on unit

size 03 through unit size 18.

All electric heat controls are built into the heater

control box.

Specify two pole break contactors or three pole

break contactors. Two pole contactors only

de-energize, while three pole contactors

disconnect.

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 capacity

Filter Section

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 Selection

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)

• 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.

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.

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.
