Trane’s Integrated Comfort systems (ICS) concept incorporates the benefits of factory-mounted, wired, and tested microprocessor controls on each piece of Trane equipment described in this section. Trane Tracer building management systems link the HVAC equipment into truly integrated comfort systems that address the critical issues facing building owners, engineers, and contractors.

Chillers

Trane chillers are available with a compressor type, refrigerant type, and capacity to meet nearly any need. These chillers are designed to provide a reliable source of chilled water and are equally suited for comfort, industrial, or process applications.

Unit controllers factory-mounted on Trane chillers provide access to information and functions within each chiller. This access allows the building management products described in this catalog to optimize the operation of each chiller individually and to optimize their performance within a chiller plant.

You can link any of the chillers listed below to a Trane ICS to provide system-level monitoring, diagnostics, and control capabilities, including sequencing chillers as well as controlling pumps and cooling towers:

• CenTraVac Centrifugal Chillers
• Series R CenTraVac Helical Rotary Chillers
• Air-cooled and water-cooled Helical Rotary Chillers
• Air-cooled and water-cooled Scroll Chillers
• Two-stage and Single-stage Indirect-fired Absorption Chillers
• Horizon Two-stage Direct-fired and Indirect-fired Absorption Chillers Refrigerant management monitoring and reporting is also available for applicable chillers.

VariTrane VAV Terminal Units

VariTrane terminal units are available with either pneumatic, electronic, or microprocessor controls (DDC/VAV).

Factory-installed DDC/VAV controls are available with all shutoff terminal units, including parallel fan-powered and series fan-powered units. Dual duct units are equipped with two Unit Control Modules (UCMs)-one for the heat duct and one for the cool duct.

The Variable Air Volume (VAV) UCM is a microprocessor-based, direct digital controller (DDC) for the VAV terminal unit. It contains the control logic to modulate the flow of supply air through the VAV terminal in response to the load requirements within the VAV zone. The VAV UCM can communicate with the Tracer 100 series building controllers and the Tracer Summit BCUs.

Commercial Self Contained Units

Trane Commercial Self Contained air conditioners efficiently bridge the gap between unitary and central systems by factory-packaging rugged commercial components in a floor-by-floor decentralized system. Multiple, independent refrigerant circuits-using the 3-D scroll compressor—provide high performance redundancy. For application flexibility, units are factory-equipped for either water-cooled or remote air-cooled condensing.
