5 Features and Benefits Micro Controls For over 10 years T rane has been working with microprocessor controls in the applied equipment markets. These designs have provided the technology that has been applied to the V oyager units.
6 Features and Benefits Excellent Part-Load Efficiency The Scroll compressor s unique design allows it to be applied in a passive parallel manifolded piping scheme, something that a recip just doesn t do very well.
7 Features and Benefits Serviceability T oday s owners are more conscious of the cost of service and maintenance. V oyager was designed with input from service contractors. Their information helped us design a unit that would get the serviceman off the job quicker and save the owner money .
8 V ariT rac T rane s changeover V A V System for light commercial applications is also available. Coupled with V oyager Commercial, it provides the latest in technological advances for comfort management systems and can allow thermostat control in every zone served by V ariT rac .

13 Application Considerations Exhaust Air Options When is it necessary to provide building exhaust? Whenever an outdoor air economizer is used, a building generally requires an exhaust system. The purpose of the exhaust system is to exhaust the proper amount of air to prevent over or under -pressurization of the building.
14 Application Considerations Acoustical Considerations Proper placement of rooftops is critical to reducing transmitted sound levels to the building. The ideal time to make provisions to reduce sound transmissions is during the design phase.
