The importance of real-world energy performance

MaxE YR screw chillers provide excellent real-worldenergy perormance the combined perormance at alloperating conditions, not just design. Because chillers inthe real world operate nearly 99% o the t ime at o-designconditions, o-design perormance is the major actor in

energy consumption. Thats why MaxE YR screw chillers areengineered or maximum eciency at both design and o-design conditions.

Unsurpassed integrated part load value

The Air-conditioning, Heating and Rerigeration Institute (AHRI)Chiller Certication Program endorses the importance oo-design analysis to compare chiller energy consumption.Measured with AHRIs Integrated Part Load Value (IPLV),most competitive screw chillers dont even come close to theenergy eciency o the MaxE YR screw chiller.

In act, the IPLV ratings o MaxE YR screw chillers are asmuch as 30% better than those o constant-speed centriugal

chillers, which have long been considered the eciencyleaders. The reason is that the screw chillers capacity-controlvalve does not create a rictional drag on eciency like thepre-rotation vanes o the centriugal chiller.

The result is unmatched energy savings, month ater month,year ater year, over the chillers entire lie.

The OptiView Control Center helps you operate your chiller moreefficiently by allowing for the precise setting of chilled-watertemperature and operating schedule.

Saves ozone and energy

To help protect theenvironment, MaxE YRscrew chillers use HFC-134arerigerant, which has zeroozone-depletion potential. In addition, they are optimized or

HFC-134a, which keeps their eciency high.

Take advantage of colder entering condenser water

MaxE YR chillers have been designed to take ull advantage ocolder entering condenser-water temperatures (ECWT), whichare naturally available dur ing o-design hours. The colder waterreduces the compressor workload and provides considerableenergy savings compared to articially holding the temperaturehigher as required by other chillers.

Powerful control center saves energy

MaxE YR chillers eature the OptiView Control Center whichuses microprocessor logic to save you energy. Operationat just 1F below the designed chilled-water-temperature

setpoint can increase chiller energy consumption by asmuch as 3%. The digital precision o the OptiView ControlCenter lets you set chilled-water temperature to a resolutiono 0.1F.

The OptiView Control Center can also be used toschedule daily operating hours and holidays. No longeris energy accidentally wasted by cooling the acility whenits not needed.

Easy to read

Johnson Controls has always pioneered powerul, yet simplerchiller control. We were the rst to apply microprocessor-based, plain-language-display, control centers to screwchillers. Now, MaxE YR screw chillers eature the ull-screen,ull-color, OptiView Control Center.

Its an advanced, microprocessor, control center that setsthe standard by presenting the most data in the clearestashion. You still get the code-ree, plain-language data.But now its even easier to read, thanks to a large, ull-colorscreen using advanced, active-matrix, display technology.

This larger display shows even more data per screen withar less button-pushing. And, that makes it much quicker andeasier to operate your chiller. To acilitate a higher level omonitoring and control, data outputs are shown in associationwith illustrations o the appropriate chiller components alayout that minimizes user conusion. For convenience, all datacan be displayed in nine di erent languages, in addition to

Imperial or SI units.

Easy to operate

With the OptiView Control Center, data input is oolproo.A dedicated keypad or numerical input minimizes keystrokeerrors. Cursor controls or screen navigation make it easyto access all input, control, and monitoring unctions. Plus,a navigation bar quickly guides you to the level oinormation you need.

Get the message quickly and graphically

Thanks to the large, active-matrix screen, detailed logs canbe read directly rom the OptiView Control Center. Instead okeystroke ater keystroke to gather sucient data rom a small,

monochrome LCD screen, a single button can reveal an array ochiller inormation that is quickly seen on a single screen. Dataoutput is provided in precise, digital orm. Valuable operatortime is reed or other important activities.

The MaxE YR screw chiller is one o the most versatilelarge-tonnage chillers on todays market. In addition toair-conditioning duty, it easily adapts to a variety ohigh-head cooling requirements, including brine coolingand thermal storage. It can also be tailored to buildingcodes around the world.

Performs well under pressure

I your application calls or cooling brine below 30F, standardcentriugal chillers just cant handle the pressure. The highercompression requirement is beyond their capability. But theMaxE YR screw chiller works well under pressure. It can easilycool brine down to 20F, which could signicantly reduce thesize and cost o the equipment using the brine.

Able to work double-duty

Thermal-storage applications oten require chillers to perormdouble-duty: during the day, its low-head, chilled-water duty;at night, its high-head, ice-build duty. In general, centriugalchillers can be built to do one or the other, but not both. The

best choice or the job is the MaxE YR screw chiller, which isable to work both the daytime and nighttime shits.

As an added benet, the MaxE YR screw chiller maximizesice production by utilizing an alternate unloading schemedesigned specically or thermal-storage applications. Thislogic maintains maximum chiller loading when conventionalchiller controls would unload the chiller. The result is shorterice-build times.
