AN EXCEPTIONALLY ENERGY EFFICIENT WATER-COOLED CHILLER RANGE FEATURING OIL-FREE TURBOCOR COMPRESSORS WITH<br />
ECONOMIZERS, FLOODED EVAPORATORS AND OFFERING A GREEN, LOW-GWP R1234ZE REFRIGERANT.<br />
A vast range of <strong>Powerstream</strong> <strong>Turbo</strong> models and options provides flexibility, tailored precisely to the customer requirements allowing to design truly efficient cooling solutions for<br />
every application.<br />
<strong>Powerstream</strong> <strong>Turbo</strong> has been designed for year-round mission-critical service. In a 24/7 world, keeping facilities up and running is critical, and we paid special attention to control<br />
and monitoring functionality, as well as to operational reliability and ease of maintenance. Due to its excellent efficiency at part-load conditions, <strong>Powerstream</strong> <strong>Turbo</strong> is an excellent<br />
economy solution for applications where the heat load is not constant and/or expected to grow. The synergy of modern technology, efficiency and reliability enables <strong>Powerstream</strong><br />
<strong>Turbo</strong> to be used in the most demanding applications.<br />

Environmental leadership<br />
Refrigerants with low global warming potential (GWP) are becoming<br />
more and more important in the refrigeration and air conditioning<br />
industry in Europe and beyond.<br />
R1234ze features low GWP of one and zero ozone depletion potential,<br />
thus providing the environmental leadership while achieving the best<br />
energy performance levels for applications.<br />
• 30 MODELS WITH CAPACITY RANGE OF 280 TO 1840kW<br />
• COMPACT DESIGN WITH 6 FRAME SIZES<br />
• REDUCED REFRIGERANT CHARGE<br />
• MINIMAL ENVIRONMENTAL IMPACT<br />
• SILENT OPERTAION<br />
<strong>Turbo</strong>cor compressors<br />
Save up to<br />
25%<br />
in operating costs*<br />
<strong>Turbo</strong>cor compressors offer the outstanding energy savings from digitally controlled,<br />
frictionless two-stage centrifugal compression and guarantees significant reductions in<br />
operating cost and environmental emissions associated with energy production.<br />
The oil-free design of <strong>Turbo</strong>cor compressors eliminates the potential for efficiency robbing oil<br />
contamination and all of the oil management accessories: oil heaters, oil pumps, oil separators,<br />
oil filters, plus oil disposal.<br />
Compressor soft-start draws only 2 amps and reduces mechanical stress, as well as the<br />
electrodynamic stresses on the power cables and electrical distribution network, extending<br />
the overall lifespan of the system.<br />

<strong>Powerstream</strong> <strong>Turbo</strong> features newly developed shell-and-tube condensers optimized for HFC and<br />
HFO refrigerants to provide the best efficiency. With high-performance tubes, new baffle design<br />
and shell, these condensers provide maximum efficiency with a low cost per kW, as well as shorter<br />
lenght and reduced weight comparing with competing solutions. Water flow within condenser is<br />
optimized to reduce the fouling and erosion risks.<br />
AVAILABLE<br />
Standard are 2 pass condensers, 4 pass condensers available as an option.<br />
Grooved connections<br />
We use grooved end connections because of their rigidity, flexibility, noise and vibration attenuation, and easy of installation and<br />
maintenance. The groove is made by cold forming or machining a groove into the end of a pipe. A gasket encompassed by the<br />
coupling housing is wrapped around the two grooved pipe ends, and the key sections of the coupling housing engage the grooves.<br />
The bolts and nuts are tightened with a socket wrench or impact wrench.<br />

Compressor efficiency comparison<br />
<strong>Powerstream</strong> <strong>Turbo</strong><br />
Competing screw water cooled<br />
Higher microchannel condenser performance results in a reduced condensing temperature,<br />
which in turn reduces compressor power consumption and increases the overall chiller<br />
efficiency, while allowable operating envelope of the compressors gets widened to a higher<br />
ambient temperature.<br />
Superior performance of the microchannel freecooling coil translates to higher freecooling<br />
capacity and increased freecooling hours, thus increasing the overall system efficiency. In the<br />
same time, the microchannel freecooling coils do not impact the fan power consumption due<br />
to the low airside pressure drop.<br />

Flooded evaporators<br />
• EXCELLENT FOR PART LOAD CONDITIONS<br />
• OPTIMIZED FOR HFC AND HFO REFRIGERANTS<br />
• EASY OF MAINTENANCE AND CLEANING<br />
The flooded evaporator enables to operate at the higher saturated evaporating temperature when<br />
compared to many others evaporator types and allows to achieve higher cooling capacity with<br />
correspondingly higher efficiency.<br />
The refrigerant pool behaves as a flywheel, allowing the controls of the flooded evaporator to track<br />
the varying load of a batch process, while optimized tube geometry ensures optimal refrigerant<br />
distribution.
Advanced controls<br />
The control hub of <strong>Powerstream</strong> <strong>Turbo</strong> chillers is a sophisticated controller and advanced software<br />
developed for efficient operation of <strong>Turbo</strong>cor-based chillers. It manages and optimizes the chiller’s<br />
performance, giving the complete control over the system for plant operator.<br />
For the efficient operation of multiple units on a single chilled water plant, the sequencing software<br />
permits interlinked operation of the complete system, thus providing optimal temperature control and<br />
minimal energy consumption.<br />
