Danfoss Releases Four New Turbocor TG Series Compressors

Danfoss’ Turbocor TG series for low-global warming potential refrigerants enables chiller manufacturers to build climate friendly and sustainable solutions that support refrigerant regulations for reducing the direct and indirect CO₂ emissions such as the European F-Gas Regulation and the U.S. Environmental Protection Agency’s SNAP regulations.

Similar to the existing Turbocor TT series compressors, the TG series compressors are oil-free, variable speed, magnetic bearing centrifugal compressors. The compressors provide outstanding full- and part-load energy efficiency and feature a small footprint, lightweight, low vibration, very low sound, intelligent controls and soft starting characteristics. The cooling capacity is lowered by about 25 percent with an equivalent model using R-134a, but the energy efficiency is slightly increased.

The new compressor models TG230, TG390 and TG520 are designed for standard temperature air-conditioning applications.

• TG230 – Delivers a nominal capacity of 230 kW (65 tons) at water-cooled conditions and 17 5kW (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 390 kW (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 520 kW (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 Turbocor TG compressors were an Honorable Mention in the 2017 AHR Expo Innovation Awards program, Green Building category.
