| Features and Benefits Quality and Reliability
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:
— 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.
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.
• 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. |
