G-CLASS V-SERIES WATER-COOLED CHILLERS

GLOBAL #1 IN OIL-FREE CHILLERS

G-Class V-series water-cooled chillers Product Overview 2

G-Class V-Series Water-Cooled Chillers

Smardt’s G-Class of chillers is distinguished by its use of environmentally-friendly refrigerants boasting

ultra-low GWP ratings. G-Class Water-Cooled V-Series Chillers are Smardt’s large-capacity chillers that

utilize Smardt’s oil-free chiller technology and Turbocor’s VTX compressors with ultra-low GWP R1234ze

refrigerant. G-Class V-Series Chillers are available from 300 to 2900 TR (1055 to 10200 kW) and can be

supplied in multiple configurations, which Smardt can customize per the requirements of your application.

G-Class Water-Cooled

Smardt has brought its extensive

experience in oil-free chiller

development, sales and service into

designing the G-Class V-Series — a

range of large-capacity water-cooled

chillers that deliver the highest level of

reliability, outstanding efficiency and the

lowest total cost of ownership.*

GClass V-Series Chillers offer valuable

benefits to owners and operators, such

as ease of installation, simple streamlined

operation and maintenance, and lower

lifetime operating and maintenance costs.

These advantages are the hallmark of

Smardt chillers.

Oil-Free Operation

Smardt oil-free centrifugal chillers use

magnetic bearings and a variablespeed drive to deliver IPLV efficiencies

that far surpass those of conventional

oil-lubricated centrifugal, reciprocating,

scroll and screw chillers.

Smardt utilizes totally oil-free Turbocor

compressor technology, achieving

the highest part-load efficiencies for

our chillers and chilled water systems

(including water-, air- and evaporativelycooled applications).

Proprietary magnetic bearings replace

conventional oil-lubricated bearings.

This eliminates the high friction losses,

mechanical wear, and the highermaintenance oil management systems

that are inherent with conventional

compressor designs.

Turbocor’s primary moving part (the

rotor shaft and impellers) is levitated

during rotation by a digitally controlled

magnetic bearing system. Position

sensors at each magnetic bearing

provide real-time feedback to the

bearing control system, 120 times each

revolution, ensuring constantly centered

rotation.

The result is oil-free operation that

delivers significant chiller energy savings

compared with standard chillers, and

provides an extended service life without

the efficiency decrease seen in oil-based

systems.

Global Number One

Smardt is the industry leader in oil-free

centrifugal chillers. Smardt pioneered oilfree centrifugal compressor technology

to provide plant owners and operators

a line of chillers that broke through

industry norms of lifetime performance,

energy conservation (reducing operating

expenses), streamlined maintenance, and

ease of operation.

Since our first oil-free centrifugal chiller in

2002, more than 10,000 Smardt chillers,

ranging from 60 TR up to 3200 TR, are

now saving money, energy and CO2

emissions across the globe.

Commitment to Environment

Smardt’s commitment to the environment

is fundamental to our chiller engineering

and design, and is central to our

company and in our products. Smardt

played a vital role in the innovation and

development of oil-free compressor

technology, and we engineered chillers

that leveraged that oil-free technology.

We develop true optimization systems

that enable plants to operate in the most

energy-efficient and effective manner

possible. And Smardt’s environmental

commitment extends to supporting

evolving refrigerant policies worldwide.

Largest Capacity Chiller

Smardt G-Class V-Series chillers are

designed for projects with ambitious

kW/TR requirements. The world’s largest

V-Class chiller, which serves a district

cooling application.

Turbocor VTX Compressor

The G-Class V-Series can be equipped

with 1–8 Turbocor VTX oil-free

compressors. The Turbocor VTX

compressors boast outstanding fullload efficiencies. On V-Series chillers,

Turbocor VTX compressors use R1513A,

R1234ze, or R515B refrigerants.

V Design Series Variations

The Smardt G-Class V-Series chiller is

also available in two versions that are

tailored for projects with special project

requirements. These are the Modular and

the Pony Express versions.

Modular Version

Smardt’s modular chillers are specially

designed to enable safe and efficient

transport in sections that fit within

a typical freight elevator. This can

avoid costly and time-consuming wall

demolition and rebuilding that might

otherwise be necessary for access.

G-Class V-Series Water-Cooled Chillers

Highlights

•Uses environmentally-friendly

refrigerants having low-GWP ratings.

•Smardt’s largest capacity range of low

GWP water-cooled chillers.

•Class leading part-load efficiencies,

achieving optimum IPLV in total capacity

range.

•Typically smaller footprint than chillers of

comparable capacity.

•Responsive chilled water control under

all conditions.

•Inbuilt redundancy with multiple

compressors.

•Designed for ease of maintenance and

serviceability, featuring field-serviceable

compressors.

•Smardt quality, acceptance tested and

pre-commissioned prior to delivery

ensuring trouble-free commissioning and

start-up on every project.

low-load “pony chiller” for reduced-load

situations such as nighttime or weekends.

This extends the chiller’s capabilities at

full or part load. It is achieved by utilizing

a combination of multiple Turbocor VTX

compressors running parallel with a

single, smaller-capacity TGS compressor.

This Pony Express compressor mix

efficiently handles all types of loads. In a

Pony Express configuration, the G-Class

V-Series Chiller can use either R513A,

R515B, or R1234ze refrigerants.

Turbocor TGS Compressor

The TGS is from Turbocor’s “green” range

of compressors, so-named because they

use next-generation refrigerants. The TGS

can operate with R1234ze (GWP <1),

and R515B (GWP is 299).*

Smardt’s G-Class chillers can be

equipped with up to eight Turbocor TGS

oil-free compressors. VFDs are built-in,

and drives are internal to the machine.

As with all oil-free compressors, the TGS

features reduced vibration and quiet

operation (up to 8dBA lower than screw

compressors) — ideal for noise-sensitive

applications.

Multiple Configurations

Smardt can configure your G-Class

V-Series chiller to fit any footprint or

height restriction, with multiple barrel

configurations available (see illustration

above).

Extended Service Life

The G-Class V-Series chiller is designed

for a service life of 25 years.

Chiller Options

Options for Smardt’s G-Class V-Series

chillers include our integrated pump

packages, and economizers.

Smardt Restart ensures that in the

event of a power failure, your Smardt

chiller is back on line as quickly as

45 seconds. Chilled water supply for

critical applications is not impacted by

intermittent power loss, eliminating the

need for additional thermal storage. The

start-up mode includes additional motor

and surge protection.

Applications

Energy conscious plant owners and

operators want optimized performance

with savings over the life of the chiller.

Smardt’s G-Class V-Series chillers

support critical-load applications in a

variety of markets, including commercial,

data center, pharmaceutical, hospital,

higher education, district cooling, hotels,

malls, and manufacturing.

Smardt G-Class V-Series Water-Cooled Chillers offer barrel configuration flexibility for

applications with restricted footprints or access challenges.
