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 high standard 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 horsepower
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.

Coil Selection
General Considerations
The cooling process should always be plotted on a psychrometric chart to be sure that desired psychrometric changes
are feasible.
When selecting a coil, it should be remembered that if the
required leaving wet bulb temperature is attained, the total
load is satisfied and vice versa. Also, when the required leaving dry bulb temperature is met, the sensible load requirement is satisfied.
A coil must meet both the total and sensible load requirement
in order to achieve the conditions desired in the space to be
cooled. Normally, the total load capacity is checked first.
However, the leaving dry bulb should always be checked.
When the sensible to total load ratio (S/T ratio) is low, the coil
selection is normally controlled by the total load even though
the sensible cooling capacity may exceed the requirement. In
some cases, if the leaving dry bulb temperature is too low,
reheat may be required.
When the S/T ratio is high, the coil selection is normally controlled by the sensible cooling even though the total capacity
may exceed that required. If the total capacity far exceeds the
requirement, a recheck on the system should be made to be
sure sufficient system capacity is available.
HI-F5 versus E-F5
Two different corrugated coil surfaces are offered to provide the most economical coil for a given application.
Normal cooling coil face velocities range from 300 to 700
FPM. For most applications, 500 to 600 FPM is recommended. See the individual air pressure drop curves (pages
11 & 14). to determine under what conditions moisture carryover might be a consideration.
Water velocity in the tubes of approximately 3 to 6 FPS is
desirable to attain high heat transfer rates with a reasonable
water pressure drop. Water velocity above 8 FPS may cause
erosion in copper tube coils.
Cooling coils should not normally exceed 54" fin height as the
condensate draining from the top portion of the coil tends to
load up on the lower portion of the coil and a significant
reduction in airflow and performance may result. Where the
fin height exceeds 54", we recommend two or more coils
banked one above the other and installed in accordance with
the recommendations shown below.
Cooling coils are normally selected to have a finned length of
three to four times the fin height for economy. Coils of several
different face dimensions are usually available to meet the
required face area.

Application recommendations, water cooling coils
1. Piping should be in accordance with accepted industry
standards.
2. When drainable coils are desired, tubes should be
installed in a horizontal position using a spirit level. If the
tubes cannot be installed level, special drain headers are
available on request.
3. Coils are unique for either right- or left-hand airflow. The
coil hand must be specified. CONNECT THE WATER
SUPPLY T O THE CONNECTION ON THE AIR LEAVING
SIDE AND THE WATER RETURN TO THE CONNECTION ON THE AIR ENTERING SIDE.
4. When cooling coils are banked two or three hi gh, a drain
gutter should be installed on the air leaving side of each
coil to collect the condensate. On high latent installations,
the condensate draining from top coils would load the
lower coils with condensate and a reduction in airflow
and performance may result. All individually installed
water cooling coils and the bottom coils of all cooling coi l
banks should be mounted in drain pans extending at
least 10 inches from the leaving air edge of the coil.
5. When fresh air and return air are to be cooled by a water
coil, care should be exercised in the design of the ductwork to provide thorough mixing before the air enters the
coil. If large quantities of fresh air below 40°F are introduced into the system, steam distributing coils should be
installed in the fresh air duct or mixing plenum as preheaters to raise the air temperature to a minimum of
40°F. This holds true unless the wate r coil is drained and
filled with antifreeze. Even though the coil is drained,
there may be enough water remaining to cause freeze
damage. The coil should be drained and flushed with
antifreeze. On any system that has fresh air introduced in
the winter season, all possible precaution must be taken
to prevent freezing.
6. Control of water cooling coils can be accomplished by
two-position control valves, modulating valves, three-way
valves, face and bypass dampers, or a combination of
these controls. Follow the recommendations of the control manufacturer regarding types, sizing and locations.
7. The pipe size 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.

HI-F5 & E-F5 water cooling coils
HI-F5 and E-F5 water cooling coils are designed for use with
chilled or well water on comfort cooling, process, dehumidifying and special applications. All water cooling coils have
vents and drains to aid drainability.
5W Water Cooling Coils are designed for general purpose
cooling. All 5W coils have heavy-gauge seamless drawn copper tube headers with carbon steel connections. This proven
header design can lengthen coil life by providing necessary
header flexibility to compensate for normal expansion and
contraction during operation. Intermediate drain headers are
available for coils that cannot be installed level.
General Formulas
TOTAL BTUH:
Total BTUH = 4.5 X SCFM X (Total Heat Ent. Air Total Heat Lvg. Air)
Where: 4 .5 = Density Std. Air x Min. / hr.
Density Std. Air = .075 lbs / cu. ft.
Minutes/hr. = 60
TOTAL BTUH:
Total BTUH = 500 x GPM x (Lvg. Water Temp. En t. Water Temp.)
Where: 500 = lbs. / gal. x min. / hr. x Specific heat water
Lbs. / gal. = 8.33
Min. / hr. = 60
Specific Heat Water = 1
SENSIBLE BTUH:
Sensible BTUH = 1.09 x SCFM x (Ent. Air DB -Lvg. Air DB)
Where: 1.09 = (Specific heat of air at 70° F) x (Min/hr.)
x Density Std. Air
Specific heat of air = .242 at 70° F
Min./hr. = 60
Density Std. Air = .075 lbs. / cu ft.
Example water cooling coil rating
The capacity data tables in this catalog rate a given coil at
the ARI conditions. For example, rate the following coil:

Entering dry bulb..................................................80°F
Entering wet bulb .................................................67°F
Entering water temperature..................................45°F
Airflow ...........................................500 feet per minute
Water velocity...................................4 feet per second
On page 9, find the table for 4-row coils, 24 x 48 inches. Follow the 5WS, 1 Serpentine column down until you reach the
08 fpi (8 fins per inch) row. This coil will provide 138.52 MBH
