Danfoss' Turbocor TG series for low-GWP (Global Warming Potential) refrigerants enables chiller manufacturers to build climate friendly and sustainable solutions which are also supporting refrigerant regulations for reducing the direct and indirect CO2
emissions such as - the European F-Gas Regulation – and the US SNAP regulation.
Similar to the current TT series compressors, the TG series compressors are oil-free, variable-speed, magnetic bearing centrifugal compressors. These products provide outstanding full and part load energy efficiency and feature a small footprint, light weight, low vibration, very low sound, intelligent controls, and soft starting characteristics. The cooling capacity is lowered by about 25% with an equivalent model using R134a, but the energy efficiency is slightly increased.
The new compressor models TG230, TG390, and TG520 are designed for standard temperature A/C applications
- TG230 – Delivers a nominal capacity of 230kW (65 tons) at water-cooled conditions and 175kW (50 tons) at air-cooled conditions. The TG230 compressor is available for nominal mains input voltages of 400V, 460V, and 575V.
- TG390 – Intended for water-cooled chillers and delivers a nominal capacity of 390kW (110 tons). The TG390 is available for nominal mains input voltages of 380V, 400V, 460V, and 575V.
- TG520 – Intended for water-cooled chillers and delivers a nominal capacity of 520kW (150 Tons). The TG520 is available for nominal mains input voltages of 380V, 400V, and 460V.
A new compressor model for medium temperature applications is also available.
- TG230 MT – Available with the same range as the standard temperature version but with the capability to extend operation down to evaporating temperatures of -10 degrees C (+14 degrees F).
In addition to these models, the TG310 has been updated to include a new model for a nominal mains input voltage of 380V. The TG310 was previously only available as 400V and 460V models.
Danfoss takes a proactive approach to further the development and use of low-GWP refrigerants to help abate global warming and to ensure the competitiveness of the industry.
Danfoss Turbocor TG compressors received AHR honorable mention in the green building category in 2017.
