Danfoss Introduces Low-GWP R-513A Refrigerant Option and Low Lift Capability for Danfoss Turbocor® TT Series Compressors
TALLAHASSEE, Fla. â€“ Danfoss, the worldâ€™s leading manufacturer of Danfoss TurbocorÂ® oil-free, variable speed, magnetic bearing centrifugal compressors, has added to its portfolio of low-GWP (global warming potential) compressors by introducing an option to use R-513A, and expanded its operating map range to cover low lift applications for the TT Series compressor family.
Danfoss TurbocorÂ® compressors are engineered and manufactured in Tallahassee and deployed around the world to help buildings reduce energy consumption and costs.
New low-GWP refrigerant option
R-513A is a low-GWP, non-flammable (A1) alternative refrigerant to R-134a that allows chiller manufacturers to meet future HFC regulations, such as the European Unionâ€™s F-gas regulation. All TurbocorÂ® TT Series compressors produced starting in December 2017 with compressor firmware version 4.1 will be compatible with both R-134a and R-513A. Existing TurbocorÂ® TT Series compressor revision F models using R-134a can be retrofitted to use R-513A by simply changing the electronic controllers.
This new refrigerant option broadens Danfossâ€™ comprehensive portfolio of TurbocorÂ® compressors using low-GWP refrigerants. In addition to the TT Series compressors, Danfoss already offers the TurbocorÂ® TG Series compressors that use ultra-low- GWP refrigerant HFO-1234ze. Similar to R-513A, HFO-1234ze allows chiller manufacturers to be in compliance with upcoming refrigerant regulations that restrict the use of HFC refrigerants.
In summary, the following Danfoss TurbocorÂ® compressors now use low-GWP refrigerants:
- Available with HFO-1234ze: Danfoss TurbocorÂ® TG Series Compressors â€“ 40 to 150 tons
- Available with R134a and R513A: Danfoss TurbocorÂ® TT Series Compressors â€“ 60 to 200 tons
New low lift capabilities
Danfoss also has expanded the operating range of its TurbocorÂ® TT Series compressors to support low lift applications such as air-cooled heat pumps â€” enabling chiller manufacturers to expand their product offering to cover even more air-conditioning and process applications. The low lift operating range allows chillers to start and operate at low condenser water temperatures that are common during cold ambient temperature conditions and gives manufacturers the flexibility to eliminate the use of expensive economizers on chillers.
â€śBy expanding the use of low-GWP refrigerants â€” including the new low-GWP R-513A refrigerant option and the existing ultra-low GWP HFO-1234ze refrigerant, Danfoss TurbocorÂ® TT Series compressors can continue to be a future-proof, environmentally-friendly solution today that complies with evolving refrigerant regulations and standards around the world, including the European Union F-gas regulation. And with the expanded low lift capability, chiller manufacturers have the flexibility to benefit from the high-efficiency variable speed, oil-free operation of TurbocorÂ® TT Series compressors in even more air conditioningÂ applications,â€ť said Jose Alvares, Vice President, Sales and Marketing, Danfoss Turbocor Compressors.
â€śDanfoss is committed to taking a proactive approach to energy-efficiency, sustainable technologies by offering multiple low-GWP refrigerant options,â€ť Alvares said. â€śThe low-GWP refrigerant offering combined with innovative oil-free, magnetic bearing technology provide the best solution for our customers to meet environmental regulations today and in the future.â€ť
