IntroductionVariTrane variable-air-volume (VAV) units lead the industry in quality and reliability and aredesigned to meet the specific needs of today’s applications. This generation of VariTrane unitsbuilds upon the history of quality and reliability and expands the products into the most completeVAV offering in the industry.Single-duct units provide an economical energy-savings system solution. This is the mostcommon type of VAV unit.Dual-duct units have two air valves. One heating valve and one cooling air valve modulatesimultaneously to provide occupant comfort. This option is also used with system concepts whichuse one valve for maintaining and monitoring 100% ventilation air.VCCFVCEFVCWFCopyrightThis document and the information in it are the property of Trane, and may not be used orreproduced in whole or in part without written permission.

Features and BenefitsConstructionUL-listed productsSafety and reliability are vital in commercial construction. All VariTrane units are listed inaccordance with UL -1995 as terminal units. This listing includes the VAV terminal with electricheaters. Additionally, all insulation materials pass UL 25/50 smoke and flame safety standards.AHRI Certified PerformanceAll VariTrane units are AHRI certified. AHRI 880 guarantees the pressure drop, flow performance,and acoustical performance provided is reliable and has been tested in accordance with industryaccepted standards. AHRI 885 uses AHRI 880 performance and applies accepted industry methodsto estimate expected “NC” sound levels within the occupied space.Casing DesignInterlocking Panels—VariTrane products are manufactured in Trane’s state-of-the-art facility in theU. S. The interlocking panels are designed using integral I-beam construction technology. Thisminimizes deformation and creates tremendous product rigidity. An additional benefit is a smoothunit exterior with few exposed screws—ideal for exposed ceiling applications. VariTrane units aredesigned for use in systems that operate up to 5" w.c. of inlet pressure.Metal Encapsulated Edges—All VariTrane units are completewith encapsulated edges to arrest cut fibers and preventinsulation erosion into the airstream. This is the standard ofcare in applications concerned with fiberglass erosion orprojects with either double-wall or externally wrapped ductwork.The Trane Air Valve—is at the heart of VariTrane terminalunits. This is where airflow is measured and controlled.Repeatability and ruggedness is vital. VariTrane products arethe most rugged and reliable available.18-gage Cylinder—limits deformation or damage during shipment and job site handling, andprovides even airflow distribution across the flow ring for unmatched airflow measurementaccuracy.Continuously Welded Seam — an automated weld process creates the highest quality continuousseam, which is “right” every time. The welded seam improves air valve rigidity and createsconsistent and repeatable airflow across the flow measurement device. The result is a truly roundcylinder, with no flat spots caused by lower quality crimping and riveting technologies.Flow Ring—The Trane flow ring is time tested to perform under themost demanding conditions. Additionally, Trane’s patented flow ringis recessed within the air valve cylinder to reduce the potential fordamage during job site handling and installation.6VAV-PRC011M-EN

Features and BenefitsExternal Shaft—This simple design provides controller flexibility and is designed to facilitateactuator field replacement.Position Indicator—The position indicator shows current air valve position to aid in systemcommissioning. Many times this can be seen from the floor without climbing a ladder.External Actuator—This feature increases serviceability, control system compatibility, and actuatorclutch access for simplified commissioning.Indoor Air Quality (IAQ) FeaturesThe oil embargo of the early 1970s created an energy crisis, which resulted in tighter buildings, andreduced ventilation rates. A fallout issue of tighter building construction was poor indoor airquality. This heightened IAQ awareness. IAQ issues have been featured in publications from thesmallest towns to the largest cities. System design should consider applicable ventilation and IAQstandards.(See your local Trane Sales Engineer or visit www.trane.com for additional information).Good indoor air quality results from units and systems which: Provide the required amount of ventilation air to each zone during all operating conditions Limit particulates from entering occupied spacesVariTrane units are designed with simplified access and a full line of insulation options including:Matte-faced—Typical industry standard with reduced first cost.Closed-cell—This insulation has an R-value and performance equivalent to matte-faced insulation.The main difference is the reduction of water vapor transmission. Closed-cell is designed for usein installations with a high chance of water formation. (It has been used to coat the exterior of chillerevaporator barrels for many years.)Foil-faced—A fiberglass insulation with a thin aluminum coating on the air stream side to preventfibers from becoming airborne. The aluminum lining is acceptable for many applications, howeverit is not as rugged as double-wall.Double-wall—Premium insulation often used in many health care applications with insulationlocked between metal lin
