DESIGN BENEFITS

Application, Design, Construction Overview - All Units

Wide Product Selection

• Ratings as low as 11,300 Btu/hr for hot water to as high as 952,000 Btu/hr for steam, based on standard conditions.

• Horizontal, Vertical, and Power-Throw™ (high velocity horizontal air delivery) models offer maximum application flexibility.

• Ratings are shown as Btu/hr (based on 2 PSI steam, 60°F entering air conditions), eliminating the need to convert from EDR.
This simplifies the matching of unit ratings to building heat loss.

Application Flexibility

• Horizontal and Power-Throw™ units are furnished with louvers for directional control of heated air. Vertical units are available
with various louver, truncone, and cone-jet deflector options to accommodate many different air distribution patterns. See
page 22 for more information.

• Units are available as low outlet temperature (LOT) models. LOT models have coils with fewer fins per inch to reduce the
output rating. This is a benefit for applications where the steam pressure exceeds 30 PSI and mounting height is critical; the
lower output results in outlet air temperatures that approximate that of standard coils at standard steam pressure. LOT models
are also well suited for dirty environments where the increased fin spacing decreases the build-up of foreign particles. Finally,
LOT models offer lower airside resistance resulting in greater allowable mounting heights and greater heat throw.

• Vertical and Power-Throw™ units are available with 90/10 cupro-nickel coils for high pressure/temperature applications, up to
250 PSI or 400°F.

• Side piping connections on the HC/HCH horizontal air delivery model allow for low clearance installations.

• Explosion-proof motors are available for use in hazardous areas. See page 8 for additional details.

• Design assures the correct relationship between air temperature, velocity, and air volume for greater heat throw; air is delivered
to the floor at maximum mounting height, increasing comfort and reducing fuel costs.

Ease of Installation/Maintenance = Reliability

• Units are compact and lightweight, requiring fewer contractor hours to install.

• All units include an electrical junction box, either integral to the motor or mounted on the unit casing, to allow for easy electrical
connections.

• All motors are totally enclosed. All single phase and explosion-proof motors include internal overload protection to protect the
motor from insulation damaging heat, resulting in longer motor life.

• Different suspension options are available for most units including threaded rod or pipe hanger adapters.

• All units are component tested for proper motor function and the coils are leak tested under pressure to ensure proper function
when the unit arrives at the jobsite.

• Fins on all units are vertical to limit build-up of foreign particles, prolonging periods between cleanings. Fins on vertical and
Power-Throw™ units are exposed for easy cleaning.

Blends with the Environment

• Quiet operation is assured through the use of carefully selected motors, fans, and scientifically designed venturi fan shrouds.

• HSB/HC/HCHC models have squared off corners for a clean, defined appearance. Vertical and Power-Throw™ units have a
pleasing circular symmetry.

• Casings are treated for corrosion resistance and finished with a neutral gray-green baked-on, electrostatically applied polyester
powder coat paint finish.

• HCH Casings are treated for corrosion resistance and finished with a Hammertone Beige baked-on, electrostatically applied
polyester powder coat paint finish.

Unit Features - Horizontal Delivery Unit Heaters

Horizontal delivery unit heaters are the most popular of all types.
These units are ideal for heating buildings with large open areas
and low ceilings. They are used to counter heat loss along outside
building walls, especially where windows are present.

In addition to the features noted on page 2, features that enhance the
popularity of the horizontal delivery unit heater are:

• HSB units have top and bottom supply and return connections.
This permits the unit to be rotated 360° without piping changes.

• HC units have side supply and return connections.
This permits the unit to be installed in low clearance areas.

• HCH high efficiency units have side supply and return
connections. This permits the unit to be installed in low clearance
areas.

• Units have a 2-piece casing for easy coil access.

• All models have tapped holes for suspension by threaded rod or
optional pipe hanger adapter kit, except HSB 18 and HSB 24
which mount directly to and are supported by the supply and
return piping.

• Serpentine copper tube coil design has high resistance to thermal
shock, even under high steam pressures.

• Absence of coil headers eliminates potential leaks and increases
coil face area without increasing overall size of unit.

• Coil designed for greater water carrying capacity with lower
friction loss.

DESIGN BENEFITS

Unit Features - Vertical Delivery Unit Heaters

Vertical delivery unit heaters are ideal for heating buildings with high ceilings or areas
that require the heater to be mounted above obstructions such as craneways. Selection
from a variety of heat throw patterns is made easy by choosing from four types of air
deflectors. Heat throw patterns range from a high-velocity narrow jet to a gentle-velocity
broad based cone of heated air.

In addition to the features noted on page 2, features that enhance the popularity of the vertical
delivery unit heater are:

• Extended motor life with the use of the standard motor cooling cone. The cooling cone
protects the motor from intense radiant and convection heat from the coil when the fan
is not running. The cone also meters a controlled volume of ambient air over the motor
to reduce motor temperature, when the motor is running.

• All models through V/VN 279 have tapped holes for threaded rod or optional pipe
hanger adapter kit.

• All models V/VN 333 and larger have angle-iron mounting bracket with 5/8" diameter hanger holes.

• All vertical units are supplied with an outlet fan guard covering the opening in the bottom of the unit.

Figure 5.1 - Unit Features

Motor-Cooling Cone – Shields motor from coil

heat - prolongs life of insulation, windings, and
lubricant. Prolongs motor life (V/VN models only).

Coil – Aluminum fins firmly bonded to tubes
for maximum heat transfer. Steam and water­carrying passages between extra-heavy steel
pipe connections are copper for model V/PT
and cupro-nickel for model VN/PTN.

Motor – All motors are totally enclosed. Single
phase and explosion-proof types include built
in thermal overload protection. Selected and
tested for operation on specific unit heater
models.

Fan – Accurately balanced to operate quietly
and at lowest possible power cost.

Junction Box – All motor wiring is terminated in an
electrical junction box either supplied on the unit
heater casing or as an integral part of the motor.

Motor Easily Removable – Modine design permits
motor to be removed through opening below the
unit especially important where heaters are installed
close to ceiling (V/VN models only).

Vertical Fins – Less opportunity for dust and dirt to
collect. Exposed for easy cleaning with air hose
and brush.

Casings – Baked-on, gray-green polyester powder
coat paint applied over rust- and corrosion­resistance treated steel lasts longer.

Unit Features - Power-ThrowTM Horizontal Delivery Unit Heaters

Power-Throw™ horizontal delivery unit heaters are ideal for heating large buildings where
a number of smaller units can be replaced by a few larger Power-Throw
results in a more economical installation. Their high velocity air delivery results in the
greatest heat throw available.

™

Power-Throw

units are also ideally suited for blanketing doors that frequently open.

Because of high velocity air delivery, care must be taken to avoid directing the air stream
at building occupants.

In addition to the features noted on page 2, features that enhance the popularity of the Power-Throw
horizontal delivery unit heater are:

• All models through PT/PTN 279 have hanger brackets with 5/8" diameter hanger holes

for 3-point suspension.

• All models larger than PT/PTN 279 have hanger brackets with 5/8" diameter hanger

holes for 2-point suspension and angle supports for 4-point suspension.

• Air distribution is controlled by a standard adjustable position horizontal louver assembly.

• The air stream can be concentrated into a high velocity jet or broadened to cover a greater area.

• Fan blades are properly balanced and pitched to move large volumes of high velocity air at relatively low sound levels.

• Refer to Figure 5.1 for features similar to the V/VN vertical models.

DESIGN BENEFITS

Unit Features - Low Water Temperature Greenhouse Heating Units

The Modine model GLW units are specifically designed to heat greenhouses
with low-temperature water. They can be successfully used in applications
where waste or reject heat from steam-electric power plants, refineries,
pumping stations, distilleries, and other industrial or processing plants can
be utilized for heating. With the ever-increasing cost of fossil fuel, utilizing
reject heat as a heat source for greenhouses is a sensible solution with the
model GLW.

Standard features include:

• Hot water coil with 1/2" O.D. copper tubes, aluminum fins, and 1-1/2" MPT
copper connections.

• Maximum operating pressure is 300 PSI, maximum operating water
temperature is 180°F

• Frame, enclosure panels, and 24" polytube transitions are galvanized steel
for corrosion resistance in humid environments.

• 1/2 HP, totally enclosed motors (1 for GLW330S, 2 for GLW660S), available for single phase or three phase voltages.

• High airflow, 3850CFM for GLW330S and 7700CFM for GLW660S, based on 150 feet of polytube duct.

Unit Sizing

Figure 6.1 - Model GLW Performance Curves

Unit performance is based on the flow rate and the temperature of
the water relative to the ambient air temperature. Refer to Figure 6.1
and the following example for determining performance.

Example:

Model GLW660S

5000

Determine heating capacity in BTU/hr for model GLW660S at
20GPM, 100°F entering water, and 70°F entering air.

4000

1. Figure 6.1 shows output in terms of BTU/hr per °F of ETD
(Entering Temperature Difference). ETD is the difference between
the entering water temperature and the entering air temperature.
For this example, ETD = 100°F – 70°F = 30°F.

Control Sequence

The following control sequence descriptions are typical for steam/hot water unit heaters:

Intermittent Fan Operation - Hot Coil

When a room thermostat calls for heat, the motor is energized. Hot water or steam is continuously supplied to the unit heater, even
when the motor is not running. When the thermostat is satisfied, the motor is de-energized.

Continuous Fan Operation - Intermittent Hot/Cold Coil

When a room thermostat calls for heat, a valve is opened, allowing steam or hot water to enter the unit heater. When the
thermostat is satisfied, the valve is closed. The fan runs continuously.

Intermittent Fan Operation - Intermittent Hot/Cold Coil

When a room thermostat calls for heat, the motor is energized. At the same time, a valve is opened allowing steam or hot water to
enter the unit heater. An aquastat may be attached to the supply or return piping to prevent fan operation until the coil is adequately
heated to avoid cold air delivery. When the thermostat is satisfied, the valve closes and the motor is de-energized.

Steam Conversion Tables - Example Calculations

Conversion factor example #1:

For an HSB340S operating at 30 lb. steam and 50°F entering air temperature, determine the following:

x Capacity (Btu/hr)
x Final air temperature (°F)
x Condensate (lb./hr)
x Maximum mounting height

Solution:

The factors/data necessary to solve this problem are as follows:

x Steam heating capacity conversion factor for 30 lb. steam and 50°F entering air is 1.43, from Table 10.1.
x Air temperature rise conversion factor is 1.40, from Table 11.1.
x The latent heat of steam at 30 lb. is 928.5 Btu/lb., from Table 12.2.
x The mounting height correction factor is 0.86, from Table 12.1.
x The standard rated capacity of an HSB 340 is 340,000 Btu/hr, from Table 13.1.
x The final air temperature of an HSB 340 at standard conditions is 120°F, from Table 13.1.
x The maximum mounting height at standard conditions is 20 feet, from Table 13.1.

= BtuS x Heating Capacity Factor = 340,000 x 1.43 = 486,200 Btu/hr

Btu

A

= (FATS - EATS ) x Air Temp Rise Factor = (120°F - 60°F) x 1.40 = 84°F

Condensate rate = Btu

Max. Mounting Height

÷ Latent Heat of Steam = 486,200 ÷ 928.5 = 523.6 lb./hr

A

= Max. Mounting HeightS x Correction Factor = 20 feet x 0.86 = 17.2 feet

A

Conversion factor example #2:

Which vertical unit heater model is required to deliver 155,500 Btu/hr at 20 lb. steam and 60°F entering air temperature. What will
be the actual capacity and rate of condensate production for the selected unit?

Solution:

The factors/data necessary to solve this problem are as follows:

x Steam heating capacity conversion factor for 20 lb. steam and 60°F entering air is 1.23, from Table 10.1.
x The latent heat of steam at 20 lb. is 939.3 Btu/lb. from Table 12.2.

= BtuA ÷ Heating Capacity Factor = 155,500 ÷ 1.23 = 126,423 Btu/hr (at standard conditions)

Btu

S

From Table 13.1, a V 139 model meets the requirement with a rated capacity of 139,000 Btu/hr at standard conditions.

The capacity of the V 139 at actual conditions will be Btu
139,000 x 1.23 = 170,970 Btu/hr.

Condensate rate = Btu

÷ Latent Heat of Steam = 170,970 ÷ 939.3 = 182.0 lb./hr.

A

Alternate Solution:

Low Outlet Temperature models are normally recommended for steam pressures above 30 lb. However, the use of these
models with steam pressure less than 30 lb. is acceptable.

Based on the example above, a V 161L model, from Table 14.1, meets the requirement with a rated capacity of 127,000 Btu/hr
at standard conditions.

= BtuS x Heating Capacity Factor =

A

The capacity of the V 161L at actual conditions will be Btu
127,000 x 1.23 = 156,210 Btu/hr.

Condensate rate = Btu

÷ Latent Heat of Steam = 156,210 ÷ 939.3 = 166.3 lb./hr.

Hot Water Conversion Tables - Example Calculations

Conversion factor example #1:

What is the capacity (Btu/hr), water flow rate (GPM), water temperature drop (°F) and final air temperature (°F) for an HSB 86 at
240°F entering water temperature (EWT) and 70°F entering air temperature (EAT)? What is the maximum mounting height?

Solution:

The factors/data necessary to solve this problem are as follows:

xHot water heating capacity conversion factor for 240°F EWT and 70°F entering air is 1.201, from Table 16.1.
xThe standard rated capacity of an HSB 86 is 60,200 Btu/hr, from Table 19.1.
x The standard rated capacity of an HSB 86 is based on water flow rate of 6.3 GPM, from Table 19.1.
x The standard high motor speed airflow of an HSB 86 is 1340 CFM, from Table 19.1.
x The maximum mounting height, at standard conditions for an HSB 86 is 16 feet, from Table 19.1.
x The mounting height correction factor for 240°F EWT is 0.89 from Table 17.2.

= BtuS x Heating Capacity Factor = 60,200 x 1.201 = 72,300 Btu/hr

Btu

A

For water flow rate, since only the entering water and air temperature conditions have changed, the water flow rate will remain

6.3 GPM.

= BtuA ÷ (480 x GA) = 72,300 Btu/hr ÷ (480 x 6.3 GPM) = 23.9°F

WTD

A

= EATA + [(460 + EATA) x (BtuA) ÷ (576 x Cfms)] = 70°F + [(460 + 70°F) x (72,300) ÷ (576 x 1340)] = 120°F

FAT

A

Max. Mounting Height

= Max. Mounting HeightS x Correction Factor = 16 ft. x 0.89 = 14.2 feet

Conversion factor example #2:

Select a vertical unit heater model that can deliver at least 150,000 Btu/hr with 160°F EWT and 60°F EAT. What will be the required
water flow rate, water temperature drop, final air temperature and maximum mounting height?

Solution:

The factors/data necessary to solve this problem are as follows:

x Hot water heating capacity conversion factor for 160°F EWT and 60°F entering air is 0.714, from Table 16.1.
x The mounting height correction factor for 160°F EWT is 1.19, from Table 17.2.

= BtuA ÷ Heating Capacity Factor = 150,000 ÷ 0.714 = 210,084 Btu/hr (at standard conditions)

Btu

S

From Table 19.1, a V 279 model will meet the requirement with a rated capacity of 212,600 Btu/hr at standard conditions.

The capacity of the V 279 at actual conditions will be Btu
151,796 Btu/hr.

= BtuS x Heating Capacity Factor = 212,600 x 0.714 =

A

Since the capacity was calculated based off standard conditions with factors for changes in entering water and air temperature
conditions, the water flow rate will remain 22.2 GPM.

= BtuA ÷ (480 x GPMA) = 151,796 Btu/hr ÷ (480 x 22.2 GPM) = 14.2°F

WTD

A

= EATA + [(460 + EATA) ÷ ((576 x Cfms ÷ BtuA) - 1)] = 60°F + [(460 + 60°F) ÷ ((576 x 5,460 ÷ 151,796) - 1)] = 86.4°F

FAT

A

Max. Mounting Height

= Max. Mounting HeightS x Correction Factor = 40 ft. (with cone-jet deflector) x 1.19 = 47.6 feet

SPECIFICATIONS

Specification for Horizontal, Vertical and Power-Throw™ Models

General

Contractor shall furnish and install steam/hot water unit heater model ______. Performance shall be as indicated on the equipment
schedule in the plans. Units shall be listed by CSA as certified to CAN/CSA-C22.2 No. 236-05 “Heating and Cooling Equipment”
and UL Std. No. 1995 “Heating and Cooling Equipment.” Additionally for Canada, the units shall have CRN registered heat
exchangers.

Casing

HSB and HC Models - Casings on model sizes 18 through 86 are 20 gauge steel (18 gauge on all other models) and consist of front

and back halves. Both halves are joined together at the top and bottom utilizing the condenser mounting screws. Casing top is
provided with threaded hanger connections for unit suspension (except for HSB 18 and HSB 24 which are directly mounted to the
supply and return piping). Fan venturi is formed in casing back half.

™

Vertical and Power-Throw

securely bolted together to form a single unit. The bottom cover has a die-formed fan venturi. The top cover incorporates a motor
cooling cone, which shields the motor from coil heat therefore prolonging motor life. An opening is also provided for circulation of
motor cooling air.

All Models - Casing shall be treated to prevent corrosion and painted with a corrosion resistant, baked, polyester powdercoat gray­green finish.

Condenser

Condenser coils are of the extended surface type, utilizing aluminum fins and DLP-type copper tubes with malleable iron supply
and return connections for HSB units, cast bronze connections for HC models and Schedule 40 steel pipe for V/PT models. Tubes
are mechanically bonded to the collars of the fins. The condensers are warranted for operation at steam or hot water pressures and
temperatures up to 150 psig and 375°F for copper coils and 250 psig and 400°F for 90/10 cupro-nickel coils.

Models - Casings consist of two circular 18 gauge steel covers. With the coil in between, the covers are

Fins are continuous across the width and depth of the condenser and are vertically oriented to minimize the collection of dirt and
dust.

Canadian Standards Association (CSA) requirements state that explosion-proof units (Power Codes 06 and 09) may not be used
with fluid temperatures in excess of 329°F or pressures in excess of 87 psig and still maintain their explosion-proof rating for
National Electric Code ignition temperature rating T3B for grain dust.

All coils are leak tested at 165 to 200 psig, air under water.

Horizontal Models - Coils are of serpentine design with horizontal tubes, vertical fins and center supply and return connections at
top and bottom of unit (except HC models, which have side connections). All tube bends are brazed. All tubes have individual
expansion bends. Copper tubes are 1" O.D. with 0.030" wall thickness (except HSB/HC 18 and 24 which are 5/8" O.D. with 0.028"
wall thickness).

return header. All tube joints are silver soldered. Copper tubes are 5/8" O.D. with 0.028" wall thickness.

Motors - See page 8 for Power Code and motor descriptions and page 23 for motor amp draw information. Motors are designed for
continuous duty and can operate in a maximum ambient temperature of 104°F(40°C).

Fans/Fan Guards - Fans are aluminum on all units and are secured to a steel hub. Each fan is balanced and is designed specifically
for the unit heater on which it is installed. Horizontal units are equipped with a combination fan guard/motor-mounting bracket. The
guard is constructed of steel rod. Vertical units are supplied with an outlet fan guard covering the opening in the bottom of the unit.

Air Deflectors - Horizontal units, including the Power-Throw
deflectors are adjustable to almost any desired position for downward, straight or upward airflow. Vertical deflectors are available
as an accessory for HSB/HC models through size 193, standard on model sizes 258-340. See page 22 for air outlet accessories for
vertical models.

Models - Coils are circular, providing for natural expansion. Each tube is continuous between supply and
