| Features and Benefits
Excellent Part-Load Efficiency The Scroll compressors unique design allows it to be applied in a passive parallel manifolded piping scheme, something that a "recip" just doesnt do very well. When the unit begins stage back at part load it still has the full area and circuitry of its evaporator and condenser coils available to transfer heat. In simple terms this means superior part-load efficiencies (IPLV) and lower unit operating costs.
FC Fans with Inlet Guide Vanes Tranes forward-curved fans with inlet guide vanes pre-rotate the air in the direction of the fan wheel, decreasing static pressure and horsepower, essentially unloading the fan wheel. The unloading characteristics of a Trane FC fan with inlet guide vanes result in superior part load performance. Rigorous Testing All of Voyagers designs were rigorously rain tested at the factory to ensure water integrity. Actual shipping tests are performed to determine packaging requirements. Units are test shipped around the country. Factory shake and drop tested as part of the package design process to help assure that the unit will arrive at your job site in top condition. Rigging tests include lifting a unit into the air and letting it drop one foot, assuring that the lifting lugs and rails hold up under stress. We perform a 100% coil leak test at the factory. The evaporator and condenser coils are leak tested at 200 psig and pressure tested to 450 psig. All parts are inspected at the point of final assembly. Sub-standard parts are identified and rejected immediately. Every unit receives a 100% unit run test before leaving the production line to make sure it lives up to rigorous Trane requirements. Ease of Installation Contractors look for lower installation (jobsite) costs. Voyagers conversionless units provide many time and money saving features. Conversionless Units The dedicated design units (either downflow or horizontal) require no panel removal or alteration time to convert in the field a major cost savings during installation. Improved Airflow U-shaped airflow allows for improved static capabilities. The need for high static motor conversion is minimized and time isnt spent changing to high static oversized motors. Single Point Power A single electrical connection powers the unit. Micro The function of the Micro replaces the need for field installed anti-shortcycle timer and time delay relays. The Micro ensures that these controls are integral to the unit. The contractor no longer has to purchase these controls as options and pay to install them. The wiring of the low voltage connections to the unit and the zone sensors is as easy as 1-1, 2-2, and 3-3. This simplified system makes it easier for the installer to wire. |
