Features and
Benefits
Micro Controls
The Micro provides unit control for
heating, cooling and ventilating utilizing
input from sensors that measure outdoor
and indoor temperature.
Quality and Reliability are enhanced
through the use of time-tested micro-
processor 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.
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 requirements.
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.
