Powerstream Turbo

SAVE UP TO 25% IN OPERATING COSTS*

Turbocor compressors offer outstanding energy savings from digitally controlled, frictionless two-stage centrifugal compression and guarantees significant reductions in operating cost and environmental emissions associated with energy production.

The oil-free design of Turbocor compressors eliminates the potential for efficiency-robbing oil contamination and all of the oil management accessories: oil heaters, oil pumps, oil separators, oil filters, plus oil disposal.

Compressor soft-start draws only two amps and reduces mechanical stress, as well as the electrodynamic stresses on the power cables and electrical distribution network, extending the overall lifespan of the system.

EXCELLENT FOR PART-LOAD CONDITIONS • OPTIMIZED FOR HFC AND HFO REFRIGERANTS • ENABLES HIGH EVAPORATION TEMPERATURES

The design of the Powerstream Turbo evaporators provides optimum system efficiency at both full and partial load operation.

The tubes in flooded evaporators are fully immersed in liquid refrigerant and enable a lower approach temperature between the refrigerant temperature in its shell and chilled water temperature in the tubes to be achieved when compared to other types of evaporators. With flooded evaporators, compressors operate at higher saturated evaporation temperatures and generate increased cooling capacities with the same power input.

The control software of Powerstream Turbo chillers maintains the level of refrigerant which is adequate for chilled water tubes to be constantly immersed, thus utilizing the full potential of the flooded evaporator even under part load conditions.

OPTIMIZED FOR HFC AND HFO REFRIGERANTS • ENHANCED THERMAL PERFORMANCE • EASE OF MAINTENANCE/CLEANING

​Powerstream Turbo features newly developed shell-and-tube condensers optimized for HFC and HFO refrigerants to provide the best efficiency. With high-performance tubes, new baffle design and shell, these condensers provide maximum efficiency with a low cost per kW, as well as reduced length and reduced weight compared with competitive solutions. Waterflow within condensers are optimized to reduce the risk of fouling and erosion. Standard are 2 pass condensers, 4 pass condensers available as an option.

SUBCOOLER • FLASH TANK

Turbocor compressors use two-stage centrifugal compression technology: the first-stage impeller raises the pressure of the refrigerant vapor halfway from the suction pressure to the condenser pressure, and the second-stage impeller raises the pressure the rest of the way. This allows using an interstage economizer, which provides advantages of capacity and efficiency improvements of up to 10% as a result of further subcooling of the liquid refrigerant.

Powerstream chiller offers two types of economizer arrangements: subcooler (standard for compressors with an economizer port) or flash tank (by request).

INTELLIGENT, CENTRALIZED CHILLED WATER PLANT CONTROL • SEQUENCE MANAGEMENT SYSTEM

The control hub of Powerstream chillers is a sophisticated controller with advanced software developed for efficient operation of water-cooled chillers. It manages and optimizes the chiller’s performance, giving complete control over the system for the plant operator.

Control software can be directly linked to the existing building management system. Integration with a BMS permits the collection and analysis of operating data of chilled water plant and helps to maintain optimal equipment settings, savings in energy, identification of trouble-prone areas, provision of maintenance schedules and the generation of safety and security alarms.

For the efficient operation of multiple units on a single chilled water plant, the sequencing software permits interlinked operation of the complete system, thus providing optimal temperature control and minimal energy consumption.
