Micro Controls
•
For over 10 years Trane has been
working with micro-processor
controls in the applied equipment
markets. These designs have
provided the technology that has
been applied to the Voyager units.
•
The Micro provides unit control for
heating, cooling and ventilating
utilizing input from sensors that
measure outdoor and indoor
temperature.
•
The Micro improves quality and
reliability through the use of time-
tested micro-processor controls and
logic. The Micro now:
— prevents the unit from short
cycling, considerably improving
compressor life.
— 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.
•
The Voyager with the Micro reduces
the number of components required
to operate the unit, thereby reduc-
ing possibilities for component
failure.
Drum And Tube Heat Exchanger
•
The drum and tube heat exchanger
is designed for increased efficiency
and reliability and has utilized
Forced Combustion Blower
Negative Pressure Gas Valve
Hot Surface Ignitor
improved technology incorporated
in the large rooftop commercial
units for almost 20 years.
•
The heat exchanger is manufac-
tured using aluminized steel with
stainless steel components for
maximum durability. The require-
ment for cycle testing of heat
exchangers is 10,000 cycles by
ANSI Z21.47. This is the standard
required by both UL and AGA for
cycle test requirements. Trane
requires the design to be tested to
2½ times this current standard. The
drum and tube design has been
tested and passed over 150,000
cycles which is over 15 times the
current ANSI cycling requirements.
•
The negative pressure gas valve
will not allow gas flow unless the
combustion blower is operating.
This is one of our unique safety
features.
•
The forced combustion blower
supplies pre-mixed fuel through a
single stainless steel burner screen
into a sealed drum where ignition
takes place. It is more reliable to
operate and maintain than a
multiple burner system.
•
The hot surface ignitor is a gas
ignition device which doubles as a
safety device utilizing a continuous
test to prove the flame. The design
is cycle tested at the factory for
quality and reliability.
•
All the gas/electric rooftops exceed
all California seasonal efficiency
requirements. They also perform
better than required to meet the
California NOx emission require-
ments.
