VAV-PRC011M-EN 7

Features and Benefits

External Shaft—This simple design provides controller flexibility and is designed to facilitate

actuator field replacement.

Position Indicator—The position indicator shows current air valve position to aid in system

commissioning. Many times this can be seen from the floor without climbing a ladder.

External Actuator—This feature increases serviceability, control system compatibility, and actuator

clutch access for simplified commissioning.

Indoor Air Quality (IAQ) Features

The oil embargo of the early 1970s created an energy crisis, which resulted in tighter buildings, and

reduced ventilation rates. A fallout issue of tighter building construction was poor indoor air

quality. This heightened IAQ awareness. IAQ issues have been featured in publications from the

smallest towns to the largest cities. System design should consider applicable ventilation and IAQ

standards.(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 spaces

VariTrane 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 use

in installations with a high chance of water formation. (It has been used to coat the exterior of chiller

evaporator barrels for many years.)

Foil-faced—A fiberglass insulation with a thin aluminum coating on the air stream side to prevent

fibers from becoming airborne. The aluminum lining is acceptable for many applications, however

it is not as rugged as double-wall.

Double-wall—Premium insulation often used in many health care applications with insulation

locked between metal liners. This eliminates the possibility for insulation entering the airstream

and allows for unit interior wipe-down as needed.

VariTrane VAV units are the most prepared IAQ units in the industry. The end result is a reliable

product designed for peak performance, regardless of job site conditions or handling.

Tracer Building Automation System

Building Automation System assures comfort within your building

Building controls have a bigger job description than they did a few years ago. It’s no longer enough

to control heating and cooling systems and equipment. Sophisticated buildings require smarter

technology that will carry into the future. Tracer controls provide the technology platform – mobile,

easy-to-use, cloud-based, scalable and open - for the next generation of data-driven, technology-

enabled services that are creating high performance buildings.

With a Trane Tracer Building Automation System, you’ll:

• Reduce operating costs through energy management strategies

• Consistently provide occupant comfort

• Enjoy reliable operation with standard, pre-engineered and pretested applications

• Easily troubleshoot and monitor either on site or from a remote location

• Reduce installation time and simplify troubleshooting

Whether factory-mounted or field-installed, Trane offers a wide range of controllers to suit virtually

any application. These units are compatible with a variety of building types and can be used for new
