Features
and
Benefits
Micro Controls
•
For over 10 years Trane has been
working with microprocessor 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 microprocessor controls and
logic. The Micro:
– 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 commercial compressor.
•
The Voyager with the Micro reduces
the number of components required to
operate the unit, thereby reducing
possibilities for component failure.
Quality and Reliability
Drum and Tube Heat Exchanger
•
The drum and tube heat exchanger is
designed for increased efficiency and
reliability and has utilized improved
technology incorporated in the large
roof top commercial units for almost
20 years.
The heat exchanger is manufactured
using aluminized steel with stainless
steel components for maximum
durability. The requirement 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 2 1 /
2
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.
*Apply to 60 HZ testing standards only.
•
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
premixed 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.
