Trane
Trane's Precedent (3 to 5 tons) and Voyager (12.5 to 17.5 tons) package units are low installation cost, help reduce maintenance requirements and energy costs.
The Precedent and Voyager models include the variable speed compressor and Trane eFlex fans, which offer increased performance and efficiency.
The e-Flex compressor and fans operate at their fastest levels when the need is high, and are modulated to slower levels when demand is lower for high part-load efficiency, this means up to 20.7 points of load performance Integrated Energy Efficiency Index (IEER) on Voyager and 20.7 charging performance points on the Seasonal Energy Efficiency Index (SEER) on Precedent models.
