Application Considerations

The Performance Climate Changer air handler, model UCCA, offers a wide range of application

flexibility while maintaining a simple, easy to install unit design. These units are a great choice

when a compact, reliable air handler is needed when budget is a critical factor.

Typical applications include many different types of buildings such as: schools, office buildings,

hospitals and retail. Applications can be either constant volume or variable air volume. Some

applications include:

• Two-pipe hydronic system for cooling and/or heating

• Two-pipe hydronic cooling system with electric heat

• Four-pipe system with dedicated heating and cooling coils

• Direct expansion (DX) split systems with hydronic heat

Standard AHU Arrangements

To complete the air-handling system, the unit must be arranged in a way that fits the available space

and meets the application requirement. The Performance air handler provides a draw-thru AHU

arrangement that places the coils and filters upstream of a ducted supply fan.

Horizontal Draw-Thru

Trane air handlers in a horizontal draw-thru arrangement provide the system components that are

required in a single-level unit. An optional blow-thru electric heater is also available. Accepted

system design practices are generally the only restrictions in a horizontal draw-thru application.
