VariTrane® Single Duct Terminal Units


VariTrane® Single Duct Terminal Units

VariTrane® variable-air-volume (VAV) units lead the industry in quality and reliability and are designed to meet the specific needs of today’s applications. Help to control comfort, indoor air quality (IAQ), noise levels, and energy consumption with the VariTrane single duct terminal units. Optional Certified Ultra-Low Air Leakage provides industry-leading energy efficiency and IAQ performance. VariTrane single duct terminal units are universally handed and optionally equipped with factory mounted and commissioned unit controllers, which reduce installation effort and startup time.  Optional Factory Installed Piping Package reduces time and risk associated with installation while improving system integrity.



The industry’s lowest air leakage rate

VariTrane’s ultra-tight two-piece casing construction helps to reduce the places where air can escape to help to reduce noise and energy losses. Units are manufactured using fully-automated, state-of-the-art sheet metal fabrication, with gasketed seams and gaps.

Tested and certified acoustical performance

Gain a proven and measurable acoustical advantage. Sound performance is tested and certified in accordance with AHRI Standard 880, and Trane stands behind the results.

Focused on indoor air quality

VariTrane delivers the proper amount of primary air/supply air to each zone during  operating conditions. Ultra-tight construction minimizes cold supply air leakage, which helps to reduce the risk of condensation that could lead to contaminants within the space. Plus, the optional LEED wrap prevents contamination during the construction phase.

Factory commissioned for superior performance

Optional factory-mounted digital Tracer controls are also factory commissioned. That means the unit operates with our best-known sequences for optimizing efficiency, quality and reliability. Sequences work in conjunction with building automation systems, making it easier to standardize VAV control over airflow and temperature setpoints, fan pressure, start-stop and more.
