Features and

Benefits

WeatherTight Top and Cabinet

• Actual shipping tests were performed

to determine packaging requirements.

Units were test shipped around the

country to determine the best

packaging. Factory shake and drop

tests were used as part of the package

design process to help assure that the

unit arrives at the job site in top

condition.

Conversionless Units

• Voyager units incorporate either a one

piece top or the Trane-Tite-Top (T³).

Each part of the top (either two or three

pieces) overlaps in such a way that

water cannot leak into the unit.These

overlapped edges are gasketed and

sealed to ensure superior water

integrity.

• The dedicated design units (either

downflow or horizontal) require no

panel removal or alteration time to

convert in the field — a major cost

savings during installation.

• Horizontal units come complete with

duct flanges so the contractor doesn’t

have to field fabricate them.These duct

flanges are a time and cost saver.

• Rigging tests include lifting a unit into

the air and letting it drop one foot,

assuring that the lifting lugs and rails

hold up under stress.

• Quick- Access (12½-20 tons) panels

reduce the number of possible water

entry points.

U-shaped Airflow

• U-shaped airflow allows for improved

• For added water integrity, Voyager has

a raised 1¹/₈" lip around the supply and

return of the downflow units to prevent

water from blowing into the ductwork.

• We perform a 100% coil leak test at the

factory.The evaporator and condenser

coils are leak tested at 200 psig and

pressure tested to 450 psig.

static capabilities.

Quality And Reliability Testing

• All parts are inspected at the point of

final assembly. Sub-standard parts are

identified and rejected immediately.

• The fan and idler arm assembly

designs have been tested to over

300,000 cycles each. Our combined

cycle testing is now over 7,000,000

cycles.

• Every unit receives a 100% unit run test

before leaving the production line to

make sure it lives up to rigorous Trane

requirements.

• All of Voyager’s designs were

rigorously rain tested at the factory to

ensure water integrity.

We test designs at our factory not on our

customers!

Features and

Benefits

• Eliminates the need for field-installed

components with its built-in anti-short-

cycle timer, time delay relay and

minimum ‘’on’’ time controls.These

controls are factory tested to assure

proper operation.

• Requires no special tools to run the unit

through its paces during testing. Simply

place a jumper betweenTest 1 andTest

2 terminals on the Low VoltageTerminal

Board and the unit will stage through its

operational steps.The unit

automatically returns control after 60

minutes to the zone sensor after

stepping through the test mode a single

time, even if the jumper is left on the

unit.

ReliaTel™

Several years ago,Trane was the first to

introduce ReliaTel into the Light

Commercial Market.That design, along

with immeasurable experience, has

provided the technology forTrane’s

second-generation ReliaTel

• As long as the unit has power and the

LED is lit, the ReliaTel is operational.

The light indicates that the ReliaTel is

functioning properly.

microprocessor controls.

ReliaTel:

• Features expanded diagnostic

capabilities when used with Trane’s

Integrated Comfort^TMSystems.

• Provides unit control for heating,

cooling, and ventilating by utilizing

input from sensors that measure

outdoor and indoor temperature.

• As an energy benefit, softens electrical

‘’spikes’’ by staging on fans,

compressors and heaters.

• Improves quality and reliability

through the use of time-tested

microprocessor controls and logic.

• The Intelligent Fallback or Adaptive

Control is a benefit to the building

occupant. If a component goes astray,

the unit will continue to operate at

predetermined temperature set points.

• Prevents the unit from short cycling,

considerably improving compressor

life.

• Intelligent Anticipation is a standard

feature of the ReliaTel. Functioning

constantly, the ReliaTel and zone

sensors work together in harmony, to

provide tight comfort control.

• Ensures that the compressor will run

for a specific amount of time, which

allows oil to return for better

lubrication, enhancing the reliability of

the compressor.

• Reduces the number of components

required to operate the unit, thereby

reducing possibilities for component

failure.

Voyager’s Low Voltage Terminal Board is

external to the electrical control cabinet.

It is extremely easy to locate and attach

the thermostat wire.This is another cost

and time saving installation feature.

Standardized Components

• Components are placed in the same

location on all Voyager units.

Familiarize yourself with one Voyager

and you are familiar with every

Voyager.

Low Voltage Connections

The wiring of the low voltage

connections to the unit and the zone

sensors is as simple as 1-1, 2-2, and 3-3.

This simplified system makes it easy for

the installer to wire.

• ReliaTel can fit all Voyager Packaged

Gas/Electrics, Cooling with Electric

Heat, and Heat Pump models.This

provides standardization of parts for

the contractors. Less money is tied up

in inventory using the ReliaTel.

Quick-Adjust Idler Arm

Colored And Numbered Wiring

With the Quick-Adjust Idler Arm, the belt

and sheaves on all 12½-20 tons can be

quickly adjusted without moving the

mounted fan motor.The result is a major

savings in time and money.

You save time and money tracing wires

and diagnosing the unit.

VariTrac™

• Contractors/owners can stock fewer

parts due to standardized components

throughout Voyager units.

When Trane’s changeover VAV System

for light commercial applications is

coupled with Voyager, it provides the

latest in technological advances for

comfort management systems and can

allow thermostat control in every zone

served by VariTrac.

Sloped Drain Pans

Voyager has the features and benefits

that make it first class in the light

commercial rooftop market. Designed

with input from field contractors and

engineers, its U-shaped airflow

performance is outstanding.

Standard on every unit.

Downflow And Horizontal Economizers

CO₂Sensing

The economizers come with three

control options — dry bulb is standard,

enthalpy and differential enthalpy are

optional.

The CO₂sensor has the ability to monitor

space occupancy levels within the

building by measuring the parts per

million of CO₂(Carbon Dioxide) in the air.

As the CO₂levels increase, the outside air

damper modulates to meet the CO₂

space ventilation requirements.The CO₂

sensor kit is available as a field installed

accessory.

If all of your customers knew about

Voyager, all would insist on it.

High Static Drive Accessory

Available on many models, this high

static drive accessory extends the

capability of the standard motor. Avoid

expensive motors and operating costs

by installing this optimized sheave

accessory.

Ventilation Override Accessory

With the Ventilation Override Accessory

installed, the unit can be set to transition

to up to 3 different pre-programmed

sequences for Smoke Purge,

Pressurization, and Exhaust.The

transition occurs when a binary input on

the RTOM is closed (shorted).This would

typically be a hard wired relay output

from a smoke detector of fire control

panel.The ventilation override kit is

available as a field installed accessory.

Application

Considerations

Application of this product should be

within the cataloged airflow and cooling

considerations.

Condensate Trap

The evaporator is a draw-thru

configuration. A trap must be field

provided prior to start-up on the cooling

cycle.

Low Ambient Cooling

This Voyager line features, as standard,

low ambient cooling down to 0°F.

Contact your localTrane Representative

for more assistance with low ambient

cooling applications.

Clearance Requirements

The recommended clearances identified

with unit dimensions should be

maintained to assure adequate

serviceability, maximum capacity and

peak operating efficiency. Actual

clearances which appear inadequate

should be reviewed with the localTrane

sales personnel.

Barometric Relief

This product line offers an optional

barometric relief damper included in the

downflow economizer accessory.This

accessory consists of gravity dampers

which open with increased pressure. As

the building air pressure increases, the

pressure in the unit return air section

also increases, opening the dampers

and relieving the conditioned space.

Unit Pitch

These units have sloped condensate

drain pans. Units must be installed level,

any unit slope must be toward access

side of unit.

Selection

Procedure

Example:

Step 3

Step 5

Table PD-3 shows that a WCD180B4 has

a gross cooling capacity of 183.0 MBh

and 129.0 MBh sensible capacity at 95

degree ambient and 6000 cfm with 80

DB/67 WB air entering the evaporator.

Cooling Capacity

If the performance will not meet the

required load of the building, try a

selection at the next higher size unit.

Step 1

Calculate the building’s total and sensible

cooling loads at design conditions. Use

the American Standard calculation form

or any other standard accepted method.

Heating Capacity

To Find Capacity at Interm iediate

Conditions

Step 1

Calculate the building heating load using

the American Standard calculation form

or other standard accepted method.

Step 2

When the design conditions are between

two numbers that are in the capacity

table, interpolation is required to

approximate the capacity.

Given the following building

requirements:

Electrical Characteristics: 460/60/3

Summer Design Conditions:

Entering Evaporator Coil: 80 DB/ 67 WB

Outdoor Ambient: 95 DB

Total Cooling Load: 172 MBh

Sensible Cooling Load: 122 MBh

Airflow: 6000 cfm

Step 2

Note: Extrapolation outside of the table

conditions is not recommended.

Size the equipment usingTable PD-15 to

match the heating loads at design

conditions.

Step 4

Verify that there will be enough capacity

by determining net capacity. In order to

select the correct unit which meets the

building’s requirements, the fan motor

heat must be deducted from the gross

cooling capacity.The amount of heat that

the fan motor generates is dependent on

the effort by the motor cfm and static

pressure.To determine the total unit static

pressure, add the following:

Total Heating Load: 88 MBh

Outdoor Ambient (Winter) 17 DB

Indoor Return Temperature: 70 DB

Airflow: 6000 Cfm

External Static Pressure: .50 in. w.g.

Rooftop - downflow configuration.

Accessories

Economizer

Use the integrated portion of Table

PD-15 for the WCD180B4 to determine

capacity at winter design conditions.The

mechanical heating portion of the heat

pump will provide 45 MBh.

External Static: 0.50 in.

Standard Filter 1 in: 0.11 in. (from table

PD-12)

Supplementary Electric Heat

Economizer Return Air: 0.04 in. (from

table PD-12)

Step 3

Because 45 MBh is less than the

building’s required heating capacity at

winter design conditions, a

supplementary heater must be selected.

88 MBh - 45 MBh = 43 MBh

Heating Capacity 88 MBh

460 volt/3 phase Electric Supplemental

Heat - at 6000 cfm

Electric Heater Size 18 kW: .06 in.

Total Static Pressure: .71 in.

Note:The Evaporator Fan Performance

Table PD-7 has already accounted for the

pressure drop for standard filters and wet

coils.

Size the equipment usingTable PD-3.

As a starting point, a rough determination

of the size of the unit must be made.This

selection will then be confirmed after

examining the performance at the given

conditions. Divide the total cooling load by

nominal BTUH per ton (12 MBh per ton);

then round up to the nearest unit size.

172 MBh/12 MBh = 14.33 (approx. 15

tons.)

From Table PD-19, at 480 volts, the 18 kW

Heater will be adequate to do the job.

18 kW 61 MBh

Therefore, the actual Total Static

Pressure is .71 - .11 = .60.

With 6000 cfm and .60 inches,Table PD-7

shows 2.66 Bhp.

From Table ED-3 select heater

AYDHTRK418A (18 kW 460/60/3).

The note below Table PD-7 gives a

formula to calculate Fan Motor Heat:

3.15 x bhp = MBh

3.15 x 2.66 = 8.38 MBh

Now subtracting the fan motor heat from

the gross cooling capacity of the unit:

NetTotal Cooling Capacity =

183-8.38=170.62

Net Sensible Cooling Capacity=

129-8.38=120.62
