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 CO<sub>2</sub> 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
<ul>
<li>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.</li>
<li>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.</li>
<li>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.</li>
</ul>
A new compressor model for medium temperature applications is also available.
<ul>
<li>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).</li>
</ul>
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.
