G-ClassAD Design Series

Smardt has brought its extensive experience inoil-freechiller development,sales and service into designing the G-Class-a range of air-cooled chillers that deliver the highest level of reliability,outstanding efficiency and the lowest total cost of ownership.

G-Class 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 IPLVefficiencies that far surpass those of conventional oil-lubricatedcentrifugal,reciprocating, scroll and screw chillers.

Smardt utilizes totallyoil-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 rotorshaft 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,l2O 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 inoil-free centrifugal chillers. Smardt pioneered oilfree centrifugal compressor technology to provide plant owners and operators α 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,O00 Smardt chillers, ranging from 6O TR up to 3200 TR,are now saving money,energy and { \mathsf { C O } } _ { 2 } （204号 emissions across the globe.

Commitment to Environment

Smardt's commitment to the environment is fundamental to our chiller engineering and design,and is manifest in 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 across the globe.

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 four 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.

Extended Service Life

The G-Class chiller is designed for a service life of 25 years.

Chiller Options

Options for Smardt's G-Class AD include our integrated pump packages, economizer,thermosyphon free cooling Smardt Lift,and Smardt Restart.

Smardt Lift enables chiller operation at full load with enhanced efficiencies when supplying chilled water at temperatures that are close to the ambient temperature. This is extremely beneficial in both high temperature chilled water applications or in seasonal operation when the ambient temperature is similar to the design chilled water conditions.

Smardt Restart ensures that in the event of a power failure,your Smardt chiller is back on line as quickly as 20 seconds. Chilled water supply for critical applications is not impacted by intermittent power loss,eliminating the need foradditional thermal storage.The start-up mode includes additional motor and surge protection.

support critical-load applications in a variety of markets,including commercial, data center,pharmaceutical,hospital, higher education, district cooling,hotels, malls, and manufacturing.
