Quality and Reliability

Forced Combustion Blower

Negative Pressure GasValve

Hot Surface Ignitor

Drum andTube Heat Exchanger

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.

Drum andTube 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 21/2 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.
