Adding Efficiency to
Existing Structures
Reaching New Heights of
Energy Efficiency
Tall structures and buildings with large amounts of
floor space benefit from water-cooled VRF technology
due to the long piping runs required. Trane VRF is
capable of serving 984 feet of pipe. Unique electronic
expansion valves employ a 2,000-step, gear-driven
design, while up to 8,400 RPMs of compressor speed
utilize the superior technology needed to achieve these levels possible.

Specialized Applications
Trane VRF systems deliver varying occupant-
Making History Modern
Historical structures have unique requirements. Many
older buildings have been constructed without adequate
ductwork, making it difficult to spec energy-efficient

appearance when thinking about how to heat and
buildings with numerous interior spaces and
cool a historical space. Trane water-source VRF uses
