ECOLOGIC and ECOLOGIC η
The long-standing Engineering symbol for efficiency, η, is now Carrier’s symbol for air-cooled chiller efficiency. The standard efficiency ECOLOGIC and high efficiency ECOLOGIC η 30GXN,R air-cooledchillers are designed from the ground up to meet the needs of today and tomorrow.

Features/Benefits
Easy installation
The 30GXN,R unit has a compact design that is up to 50% smaller than earlier air-cooled chillers. The compact footprint can yield substantial installation savings by requiring less structural steel, concrete, security fencing or architectural screening. The 30GXN,R unit isdelivered as a complete package for easy installation. A quick start-up is assured once installation is complete, since each 30GXN,R unit is manufactured at an ISO 9001:2000 listed manufacturing facility to ensure quality. In addition, all units are factory run tested under full load to provide reliable start-up.

Easy to live with
The 30GXN,R units have a quiet, lowvibration design featuringrotary screw compression and AeroAcoustic™ fans that reduce sound levels and improve sound quality. Lower sound levels help avoid the need for costly sound barriers that may be needed with other screw compressor chillers. The 30GXN,R controls are fully automatic. The leaving-fluid temperature is directly controlled, and the enteringfluid temperature is continuously monitored to detect load and flowchanges. This combination (an exclusive ComfortLink controls advantage) provides the most precise temperature

control available. In addition, the 30GXN,R units can handle both quick and slow-loading applications. The 30GXN,R units use chlorine-free HFC-134a refrigerant to help protect the Earth’s ozone layer and your investment. From a servicestandpoint, the 30GXN,R units offer the following features: • Use of HFC-134a refrigerant, a single compound refrigerant that is easy to handle, readily available, and not subject to phase out • Mechanically cleanable cooler • Twin screw compressors require little routine service or maintenance • Easy viewing of suction and discharge pressures and temperatures using either standard or accessorydisplay module

ComfortLink controls are fully communicating, and are cable ready for connection to a Carrier Comfort Network (CCN). Occupancy scheduling, temperature and pressure readouts, and the ComfortLink handheld Navigator™ clear language display compliment the standard features, linking you to a world of carefree comfort. The 30GXN,R chillers are built on the legendary performance of theCarrier model 30G Flotronic™ chiller and share many of the same time-proven features and technologies providing easy operation, quick installation and start-ups that save you money!

pumping system, and not just at the chiller.

Energy management made easy
While 30GXN,R chillers have many standard features such as network communications capability and temperature reset based on return fluidtemperature, they can also expand as needs change. Supply temperature reset based on outside air or space temperature is as easy as adding a thermistor. The Energy Management option can allow you to take advantage of changing utility rate structures with easy to use load shedding, demand limiting and temperature reset capabilities. Reset triggered via 4 to 20 mA signal makes integrating from anexisting building management system simple. The 30GXN,R comes standard with the ComfortLink Navigator display, available with optional remote service connection port, and GFCI convenience outlet (60 Hz only). The Navigator displays information in a clear language format. The 4-line 20-character display can be plugged into the unit at either the control panel or at the remote service port. This allows...
