VTT is helping chiller systems achieve efficient, reliable operation

Introducing the new VTT series of Danfoss Turbocor^® compressors, the pioneer of oil-free, variable speed,magnetic bearing technology. Based on the proven Danfoss Turbocor^® TT series compressor platform, VTT (Variable Twin Turbo) oil-free compressors feature patented IntraFlow™ technology and provide the highest full- and part-load efficiency in the industry as well as superior turndown.

The VTT series also extends Danfoss' existing compressor capacity range up to 400 tons / 1430 kW.

Exclusive IntraFlow™ patented technology
Innovative and patented IntraFlow™ technology allows the VTT series of compressors to eliminate the cost and complexity of inlet guide vanes or variable geometry diffusers and, at the same time, simplifies the capacity control, extends the stable operating range, and improves compressor efficiency.

In brief, IntraFlow™ directs a fraction of the flow from the volute exit to the inlet of the first-stage diffuser through a series of nozzles. This injection of flow into the first stage diffuser provides aerodynamic incidence control to give VTT compressors the largest stable operating range of any centrifugal compressor.

• Highest full- and part-load efficiency in the industry
• Superior turndown
• Extended stable operating range
• Eliminates the need for Inlet Guide Vanes or other types of mechanical diffusers

Danfoss Turbocor^® oil-free compressors VTT are designed to allow OEMs to meet the stricter chiller efficiency requirements expected in ASHRAE 90.1-2016 using either Path A or Path B.

Applications & data:

• Danfoss Turbocor^® oil-free compressors VTT are designed to meet the operational requirements of water-cooled or evaporatively cooled chiller applications and have nominal capacity ranges from 200 to 400 tons (700 to 1430 kW).
• Due to the unloading capabilities of the compressors, the VTT series is ideal for buildings that operate 24/7, such as data centers and hospitals.
• The VTT Series is available for voltage applications between 380 and 460 Volts and carries the ETL mark.

Features and benefits: 

• From 200 to 400 TR - 700 to 1430 kW with a R134a single compressor
• Up to 2 MW W/C and evaporative chillers with unmatched energy efficiency
• Innovative IntraFlow™ technology simplifies capacity control, extends stable operating range and improves efficiency

Experience the benefits of oil-free technology in high lift applications

The world’s first oil free compressor optimized for high lift applications.

The Danfoss Turbocor^® TTH/TGH oil-free centrifugal compressor is specifically designed for high lift applications such as air-cooled chillers in hot ambient climates, heat recovery, heat pumps or thermal storage.  The TTH/ TGH compressor provides a high-performance alternative to the traditional oiled screw compressor that is more efficient, quieter and with a smaller physical footprint.

In addition, oil free technology has no performance degradation over the life of the compressor unlike traditional oiled screw compressors which can incur performance degradation due to excess oil and mechanical wear over time.

As part of the Danfoss long-term refrigerant strategy, the TTH/TGH compressor is available with low GWP refrigerant options. The TTH model utilizes R134a and is compatible with non-flammable R513A while the TGH model uses ultra-low GWP HFO-1234ze.

Features and benefits:

 

 

• Zero performance degradation and no mechanical wear over the life of the compressor
• Outstanding energy efficiency at part load
• Compact, lightweight and simple system design reduce installation and maintenance costs
• Soft Start reduces in-rush current at startup
• Exceptionally quiet operation - 70 dB(A), up to 8 dB(A) quieter vs comparable size screw compressor
• ETL Listed and CE Compliant
