DECADES OF DEVELOPMENT

The Smardt engineering, development and manufacturing team shares more than 20 years’ experience working together with magnetic bearings and oil-free centrifugal chillers – a greater body of oil-free centrifugal experience than any other chiller company in the world. The Group’s long experience actually developing the Turbocor compressor technology and its applications brings the definitive high- performance range of water-cooled and air- cooled oil-free centrifugal chillers to the world market. The team makes sure each Smardt chiller saves its owners money throughout its long operating life– money in operating costs, money in maintenance costs, money because of high reliability and redundancy which practically removes mechanical risk altogether

Algorithms used in all Smardt chiller controllers further enhance the intelligence built-in to the compressor – achieving further efficiencies across each compressor’s operating map, and further, optimizing each compressor’s intrinsic part-load efficiencies in delivering integrated chiller efficiencies that are currently unmatched.

6000+ UNITS AND COUNTING

Smardt’s worldwide leadership in chiller energy efficiency means there are more Smardt oil-free centrifugal chillers operating across the globe (some 6000 already) than any other chiller brand – testament to their continued reliable delivery of energy savings in an array of different applications.

SMARDT Product Ranges

WATER-COOLED PACKAGED CHILLER 

RANGE 60 TR THROUGH 2500 TR

SMARDT V-CLASS WATER-COOLED CHILLERS

350 TO 2500 TR

R-134a, R-513a and R-1234ze

Smardt uses Turbocor’s VTT compressor range to bring new levels of efficiency, reliability and turndown to the large watercooled chiller market – up to 2500 TR. The VTT design – two-stage with enabled addition of Smardt economizer technology - continues the use of proprietary magnetic bearings in oil-free operation with integrated variable speed drive. Both drive and motor are actively cooled by refrigerant, and robustness enhanced with built-in DC coils and fuses.

Capacity control is precise and simple, using an elegant flow valve system which eliminates the need for inlet guide vanes or mechanical variable diffusers. This enhances full load efficiency – conservatively, 

0.55 kW/TR is routinely delivered. V-class offers the highest part load efficiency on the market – conservatively, below .35 kW/TR, while also allowing greater turndown – below 7% of maximum capacity is often utilized in cooler climates.

The Smardt systems design approach allows continuous chiller operation during chiller maintenance – vital in mission-critical applications. Smardt’s V-class installations so far have all occurred within the demanding application requirements of data centers or pharmaceutical manufacturing.

District cooling applications are an obvious extension, as is replacement of multiple-chiller plants using 4160v power.

In summary, the V-class range offers the lowest life-cycle costs in its class.

SMARDT G-CLASS WATER-COOLED CHILLERS

90 TR TO 880 TR

R-1234ze

Designed, developed and tested by Smardt Germany, the G-class range uses low-GWP refrigerant 1234ze – with a GWP 99% lower than current HFC-134a. Other low-GWP refrigerants and refrigerant blends are currently under test.

With 1234ze, Smardt G-class water cooled chillers deliver a full load efficiency of 0.52 kW/TR and an IPLV efficiency below 0.31 kW/TR, with an extended range of operating temperatures (to 40 deg F CWT).

As with Smardt’s other water cooled oil-free centrifugal ranges, built-in redundancy minimizes chiller downtime, and systems integration allows continuous operation during maintenance.

In summary, the Smardt G-class offers the lowest lifecycle cost in its low-GWP class.

SMARDT T-CLASS WATER- COOLED CHILLERS

60 TR TO 900 TR

R-134a

Several thousand of these oil-free centrifugal machines are operating efficiently across the world, some for more than 10 years.

In Thailand, since 2010 when the very first SMRDT chiller arrive to site until today with more than 100,000 TonR Total cooling capacity installed.

All use Turbocor’s TT-series oil-free centrifugal compressors.

The array of available options is probably the widest on the planet.

In configuration, you can choose between 

and optional alloys for use in seawater or difficult fluids, optional shock resistance or other special condition requirements such as marine application?

AIR-COOLED PACKAGED CHILLER RANGE

60 TR TO 600 TR

The Smardt air-cooled range offers the smallest footprint, the quietest operation and the highest air-cooled operating efficiencies in its market.

Condenser coils use a V configuration to optimize heat rejection and footprint. Coils are baked and double-coated as standard with sealed edges as standard, to extend the coil’s physical protection from environmental corrosion.

REMOTE AIR-COOLED CONDENSING

Remote location of the condenser can be a preferred option in some applications. Smardt can supply a full package if desired, or on a condenser-less basis.

“QUIETEST IN THE INDUSTRY!”

Standard Smardt air cooled chillers are over 70% lower in sound power than a standard screw machine. Even lower sound levels are deliverable when you need them.

EVAPORATIVE PRE-COOLING FURTHER DROPS POWER CONSUMPTION

Use of evaporative pre-cooling to lower the incident air temperature on the coil can dramatically reduce energy consumption, effectively shifting heat rejection from ambient dry bulb (95 deg F or 35 deg C) towards ambient wet bulb (say 75 deg F or 24 deg C). In warmer, dryer climates, Smardt reference sites show further savings of over 30% compared with normal Smardt air-cooled operation.

T-CLASS AIR-COOLED CHILLERS

70 TR TO 600 TR

Smardt’s T-class AD series air cooled oil-free centrifugal chillers offer new standards in oil- free centrifugal efficiency, especially when ambient conditions allow the use of free cooling modalities. All fans are EC variable speed; all condenser coils use low pressure drop microtubes. V-coil condenser designs protect the chiller against damage from dust, dirt, hail and ultra-violet rays. Special coatings protect against insidious corrosion. Smardt engineers work hard to use all available opportunities to drive high efficiency, low maintenance and long life while keeping designs as elegant and robust as possible.

This new Smardt air cooled chiller is now installed in a large data center. This mission- critical market sector accounts for a large proportion of the Smardt installed base.

Sound ratings are typically below 85 dBA at 1 meter – some 20 dBA lower than orthodox screw chillers in air cooled mode. Measurements are made in accordance with the AHRI-575 standard.

Additionally, the chiller’s base frame is heavy duty hot-dip galvanized and the screws and fixings above the base are stainless steel as standard for optimal corrosion protection.

Advanced electronics mean that mechanical forces can be managed with extraordinary tolerances, achieving very high reliability. Not a surprise, when shaft position is automatically measured and adjusted 120 times per revolution.

Smardt chillers optimize the benefits of the revolutionary Turbocor oil-free centrifugal technology. Above, the TT300 compressor delivers 60 to 90 TR while the TT400 delivers 120 to 150 TR and the TT500 delivers over 200TR

Oil Free Centrifugal Technology

Oil-free centrifugal compressor technology boosts energy efficiency, cuts operating costs and is now well-proven worldwide.

Smardt oil-free centrifugal compressors use magnetic bearings and variable-speed drive to deliver a quantum leap in IPLV efficiencies compared with conventional oil-lubricated centrifugal, reciprocating, scroll and screw compressors.

The totally oil-free Turbocor technology achieves the highest part-load efficiencies for chillers and chilled water systems (including water-, air- and evaporatively-cooled applications).

Proprietary magnetic bearings replace conventional oil-lubricated bearings, eliminating high friction losses, mechanical wear and high-maintenance oil management systems to deliver chiller energy savings of 35 percent and more over conventional chillers while ensuring long-term reliability.

Turbocor’s one main moving part (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.

High-speed variable-frequency operation affords outstanding part-load efficiency, compactness and extraordinary soft-start capacity. An inlet guide vane assembly trims low-load capacity and is digitally integrated with the variable-speed control to optimize energy efficiency and compressor performance throughout the full range of load and temperature conditions.

The compressor’s onboard digital controller proactively manages compressor operation while allowing external control and web-enabled monitoring of performance and reliability information.


HFC-134a refrigerant cools electronic and electromechanical components to assure maximum efficiency and safe operation.

Very low sound and vibration levels eliminate the need for expensive attenuation.

As this comparative study showed, over 20% of a lubricated chiller’s operating efficiency can be routinely lost in its early years as a result of oil clogging of heat transfer surfaces. No oil means no such problem.

The well-known ASHRAE study (Research Project 751) concluded that typical lubricated chiller circuits show reductions in design heat transfer efficiency of 15-25%, as lubricant accumulates on heat transfer surfaces, denatures and blocks normal thermodynamic transfer processes. Logically, no oil in your chiller means no oil contamination over time, so design efficiency is maintained effortlessly.
