A History of Performance

For more than a decade, Carrier 30G FlotronicTM chillers have been utilized in schools, offices and in industrial process applications worldwide. With a history of proven performance and reliability, Carrier's engineers have combined advanced temperature controls, third generation screw technology and chlorine free refrigerant HFC- 134a to develop the 30GX EcologicTM chiller.

Since Dr. Willis H. Carrier's first centrifugal compressor in 1922, Carrier Corporation has been recognized for its technological and environmental leadership. This history of innovation includes such advances as mixed flow turbine-assisted centrifugal chillers (19XTR) that have earned Carrier the U.S. Department of Energy's National Energy Award.

Rotary Screw Compression

Carrier EcologicTM chillers utilize the Carrier Carlyle 06N Geared Twin screw compressor. Built in a state of the art facility in Syracuse, New York (U.S.A.), these third generation rotary screw compressors are designed, tested and built to the high standards that are expected from the world's leader in comfort cooling.


Liquid Cooled Carrier Carlyle 06N Rotary Screw Compressors are ideally suited for use with HFC-134a refrigerant.

Since operating pressures with HFC-134a are about 30% lower than conventional systems using HCFC-22, internal rotor blowby is reduced, thereby increasing compression efficiency and reducing chiller plant size. And, since the Carlyle 06N compressor is liquid cooled, it has a low internal pressure drop that makes it ideally suited for use with medium pressure HFC-134a refrigerant.

All 06N compressors used in EcologicTM chillers are equipped with the advanced Carrier Compressor Protection Module (CPM). The CPM protects compressors from phase-loss, reverse rotation, over/under voltage conditions, and ground current failures that can lead to motor burn-out, system contamination and costly system clean-outs.  

The EcologicTM Comfort Advantage

Building on the proven FlotronicTM temperature control, Carrier has added many new features to the 30GX EcologicTM chiller to ensure carefree comfort. The Carrier exclusive leaving temperature control with return compensation allows the flexibility to use either variable flow systems or conventional primary/secondary systems to ensure process control or building comfort.

EcologicTM chillers (like FlotronicTM chillers) utilize the 1500 step long-stroke electronic expansion device for unsurpassed refrigerant control, temperature control and part load performance.

All 30GX air cooled chillers with EcologicTM controls are cable ready for connection to Carrier Comfort Network (CCN) systems, or can be used in stand alone operation. And, with the standard accessory controls module, EcologicTM chillers can accept demand limit, dual setpoint and outside air temperature reset signals via 4-20 mA connection, making these chillers ideal in retrofit applications with existing building management (BMS) system.
The standard clear-language display of the EcologicTM control is easy to operate and incorporates many value-added features

The Texas Dept. of Transportation is an example of how the 30GX EcologicTM chiller works.

A Sound Investment

Unlike many competitive screw compressors that have earned a reputation for being loud, the Carrier Carlyle gear twin screw compressors used on EcologicTM chillers have been specifically designed for quiet operation by eliminating the annoying frequencies that direct-drive compressors often emit.

Standard Aerocoustic fans move more air, more efficiently, and with less noise.
And, since condenser fan noise can often be just as annoying, all EcologicTM chillers come standard with the low noise AeroAcoustic fan. Developed in conjunction with the United Technologies Research Center, the Aeroacoustic fan moves more air, more efficiency, and with less noise.

 

Out of sight

By incorporating many of the latest innovations from Carrier's large tonnage Rotary centrifugal chillers, 30GX EcologicTM chillers are surprisingly small. High efficiency flooded coolers with close coupled compressors and refrigerant economizers are but a few of the features that help make the 30GX up to 50% smaller than many of the units they will replace as well as many competitive machines. This smaller footprint means easier handling, lower shipping costs and more cooling capacity in retrofit situations where space is limited.

The Bottom Line

The bottom line is a packaged air-cooled liquid chiller that is the logical choice. A low sound, high-efficiency packaged chiller with many of the factory options that will reduce your installation and operating costs today, and the EcologicTM control and HFC-134a refrigerant that will provide you with longer term peace of mind and carefree comfort.
