A pioneer in corrugated fin de velopment
HI-F Means High Efficiency
A principal factor governing fin heat transfer efficiency is the
boundary layer film of air adhering to any fin surface. This
boundary layer insulates the fin, severely reducing the rate
of heat exchange.
The advanced rippled-corrugated HI-F design creates a
state of continuous turbulence which effectively reduces the
boundary layer formation. The exclusive rippled edge
instantly deflects the incoming air to create initial turbulence. A succession of corrugations across the fin depth, in
conjunction with the staggered tubes, increases the turbulating effect and eliminates the "dead spots" behind the
tubes. In this manner, the HI-F design establishes a new
high in heat transfer efficiency yielding sharply increased
performance. The rippled fin edge also strengthens the fin
edge and provides a pleasing overall appearance.
E-F Means Energy Efficient
The term "energy efficient," which is used to describe how
well a system utilizes energy, has become a common
expression in the HVAC industry.
With costs of energy rising, the need for cutting operating
expenses is apparent. Lowering the air pressure drop
across the face of the coil will reduce the fan brake h orsepower requirement and fan motor electrical demand. The
need to cut operating energy expenses is met by the E-F fin
surface. The smoother fin design of the E-F surface results
in lower operating costs over the life of the equipment.

Staggered Tube Design
For High Performance
The more moving air in contact with the tubes in the coil, the
more performance obtained from the total available surface.
The staggered tube design exposes the tubes to more moving air than the in-line design. The geometry of the staggered tube design also allows the rows to be spaced closer
together. This results in a more compact coil providing
higher capacities.

Circuiting arrangements
Hot water coil circuitings
Type 5WB, 5WQ, and 5WH coils are designed to produce
high capacity with limited water quantity. High performance is
achieved by the increased water velocity obtained from the
circuiting of these coil types.
Type 5WL and 5WS coils are designed and engineered to
meet most applications requiring normal water quantities
and normal water pressure drop.
Type 5WM and 5WD coils are designed specifically for
applications that require high water quantities and low
water pressure drop.

Hot water (booster) coil circuiting
Type 5BB, 5BS and 5BD hot water booster coils are designed
for use in reheat applications and to produce very high
capacities in a limited space. They are particularly suitable for
installation in the supply duct to each room for individual
room control.
Type 5BB and 5BS coils are single circuited and are available in one and two rows deep. Type 5BD coils are double
circuited and are available in two rows deep.

Design features
A variety of fin spacings
Standard water heating and booster coils are available with
06, 07, 08, 09, 10, 11, 12, 13 or 14 fins per inch. The wide
variation in fin spacing permits accurate balancing of coil
capacities with the design load.
Copper tube headers
To provide extended coil life, 5W water heating coils are
manufactured from heavy-gauge seamless drawn copper
tube. Intruded tube holes provide maximum brazing surface for maximum strength. Copper tubes brazed to copper
headers offer a combination of similar materials which
eliminates unequal thermal expansion and greatly reduces
stress in the tube-header joint.
Full fin collars
Efficient fin presses perform multi-stage operations to draw
full fin collars with wide, smooth surfaces that completely
cover coil tubes. Our full fin collars actually form a tube
within a tube, yielding greater strength and maximum heat
transfer.
Lack of sharp collar edges makes our coils easier to clean;
smoother fin collars retard lint and dirt accumulations.
Flanged casings
Double flanged galvanized steel casings on all wa ter heating coils provide greater strength and better support for
easier coil stacking. Moving and handling operations are
simplified by the heavy coil casings.
Top and bottom casing flanges are turned back to form two
channel sections in a "box" shape, providing maximum
strength and durability.
Hot water booster coils can be furnished with flanges for
slip-and-drive fasteners or full flanged casings for standard
installations.
McQuay Catalog 412-6 7
General specifications - 5W and 5B coils

Application recommendations
1. Piping should be in accordance with accepted industry standards.
2. When drainable coils are desired, tubes should be
installed in a horizontal position. Use a spirit level. If
the tubes cannot be installed level, special drain
headers are available on request.
3. Connect the water supply to the leaving air side and
the water return to the entering air side of the coil.
Connecting the supply and/or return in any other
manner will result in a reduced performance.
4. Hot water coils are not normally recommended for
use with entering air temperatures below 40° F;
however, special high pressure water coils have
been used very successfully on high temperature
hot water jobs with low entering air temperatures
when correctly controlled. No control system can be
depended on to be 100% safe against freeze-up
with water coils. Glycol solutions or brines are the
only freeze-safe media for operation of water coils
for low entering air conditions.
5. When fresh and return air are to be heated by a hot
water coil, care should be used in the design of the
ductwork to provide thorough mixing before the air
enters the coil.
The return air should always enter the bottom of the
duct. Fresh air should enter the top of the duct. The
greater the distance between the point of mixing an d
entrance to the coil, the better the application.
Temperature control elements should be located
to sense the lowest temperature air that will enter
the coil.
Always install gasketed fresh air dampers which
are automatically controlled to close whenever the
water leaving the coil is too cool, or the fan stops.
Care should be used in designing fresh air intakes
to prevent stack effect (or wind) from forcing cold
air through the coils when the fan is shut down.
Two sets of dampers are frequently required. Continuous water circulation through the coils at all
times is recommended when fresh air mixtures are
used.
Face and bypass dampers are recommended in
preference to valves for controlling leaving air temperature from hot water coils used to heat fresh air
mixtures.
6. Two-position or modulating valves can be used to
control hot water coils on booster applications.
Follow standard recommendations of the control
manufacturer regarding sizing of valves and location of temperature controllers for these applications.
7. Pipe sizes for the system must be selected on the
basis of the head (pressure) available from the circulating pump. It is recommended that the velocity
should not generally exceed 8 feet per second and
that the pressure drop should be approximately 3
feet of water per 100 feet of pipe.
Hl-F5 vs. E-F5 coils
Two different coil fin surfaces are offered. This results in a more economical coil selection for a given application.
Type. Tube Dia. Fin Type Application
Hl-F5 5/8”
E-F5 5/8”

Hi-Efficiency
E-F

Efficiency
Gives highest heat transfer rate for a given amount of surface.
Smoother fin corrugation than the Hl-F5 results in a lower air pressure drop and
lower fan bhp requirements. The cost of additional surface can be amortized by
the kw savings.
Cleanable coils
5W type water coils are also offered in a cleanable tube co nfiguration. The cleanable coils are identical to 5W coils with
the addition of removable plugs in the header(s) to faci litate
tube cleaning. Type 5PQ, 5PH and 5PS coils have removable
plugs on the coil connection end only.
Type 5QQ, 5QH and 5QS coils have removable plugs on
the opposite connection end only. 5K, 5P and 5Q 1-row
and 2-row cleanable water heating coils may be outside the
scope of ARI standard 410.

See Table 2, page 10, under 24 FH dimension to determine
which coil type is available for the number of feeds desired
(or closest to desired). Type 5WB and 5WQ 1-row coils have
four feeds. Check type 5WB first because this is the most
economical coil.
6.Determine water pressure drop: Follow the example on
page 18. Read the header side and tube side pressure
drop. In this example the header side pressure drop = 1.4
ft. H
These pressure drops must be adjusted by using the temperature correction factors. At 185° F average water temperature this results in the following pressure drops:
tube = 1.2 x 2.2 = 2.64; header = 1.48 x l.2 = 1.77. Therefore, the total pressure drop = 2.64 + 1.77 = 4.42 ft. H

FA = Altitude Conversion
Factor from Figure 2
The CFM of standard air should be
used to determine face velocity
through the coil, which in turn is
used to determine heat transfer values, and the air pressure drop
through the coil.
The air pressure drop value taken
from Figures 6 and 8 must be converted to altitude to be used for
static pressure calculations. To convert the air pressure drop from standard air at sea level to the air
pressure drop at proper altitude use
the following equation:
Pressure Drop = Pressure Drop at Sea Level
at Altitude FT x F

Engineering guide specifications
Furnish and install as shown on the plans and as described in the tabulated specifications, McQuay ARI certified water
cooling coils 5W, 5M or booster coil 5B. The coil shall be of extended surface, staggered tube, rippled plate fin type.
PRIMARY SURFACE: The primary surface shall be round seamless (5/8” O.D.) (1/2” O.D.) copper tube staggered in the
direction of airflow. T ubes shall be on 1-1/2” or 3” centers. High pressure coils shall have cupro-nickel tubes and headers.
SECONDARY SURFACE: The secondary surface shall consist of rippled aluminum plate fi ns for higher capacity and
structural strength. Fins shall have full drawn collars to provide a continu ous surface cover over the entire tube for maximum heat transfer. Bare copper tube shall not be visible between fins. Tubes shall be mechanically expanded into the fins
to provide a continuous primary to secondary compression bond over the entire finne d length for maximum heat transfer
rates.
CASINGS: Casings shall be constructed of continuous galvanized steel with 3/8” diameter bolt holes for mounting on 6”
centers. Coil side plates shall be of reinforced flange type for greater strength and ease of stacking coils in banks (Booster
coils shall be furnished with flanges for slip-and-drive fasteners or full flanged casings for standard installation.)
COILS: Coils shall have the connections located to permit (unique) (universal) mounting of the coil for (right- or left-)hand
airflow and have equal pressure drop through all circuits. Coils shall be circuited to provide the maximum mean effective
temperature difference for maximum heat transfer rates. All coils over 45” fin length shall be furnished with four fin angles
to properly position the coil core.
WATER HEATING COILS: Headers shall be seamless copper tubing. The hea ders shall have intruded tube holes to provide large brazing surface for maximum strength and inherent flexibility. The complete 5W coils shall be tested with 315
pounds air under water and be suitable for operation at 250 psig and 300° F . High pressure coils shall be suitable for operation up to 400 psig and 400°F. Individual tube test and core tests before installation of headers is not considered satisfactory. Hydronic tests alone shall not be acceptable.
BOOSTER COILS: Connections on booster coils shall be 1/2” NPT wrought copper. The complete 5B coils shall be tested
with 315 pounds air under water and shall be suitable for use up to 250 psig and 300°F.
CLEANABLE TUBE COILS: Cleanable coils shall have removable plugs on (th e coil connection end) (the opposite coil
connection end) (both ends). Headers on cleanable water he ating coils shall be seamless copper tubing. The headers
shall have intruded tube holes to provide a large brazing surface for maximu m strength and inheren t flexibility. The complete 5W coils shall be tested with 315 pounds air under water and shall be suitable for use up to 250 psig and 300° F.
One -and two-row cleanable water heating coils may be outside the scope of ARI standard 410.
CAPACITIES: Coil capacities shall be as outlined in the tabulation and substantiated by computer generated output.
