Siemens converter a cool idea

With the sealed cabinet system, the liquid-cooled Sinamics S120 cabinet modules frequency converter is ideal in harsh environments.

June 2015

The liquid-cooled Sinamics S120 cabinet modules frequency converter from Siemens is a converter for use in harsh ambient conditions. Efficient heat dissipation means there is no need for air conditioning, which markedly reduces energy consumption. Both optimised layout and effective cooling have helped to reduce the module’s footprint. Since the liquid-cooled Sinamics S120 cabinet modules frequency converter is integrated into commercially available engineering tools it also makes ordering easier.


Thanks to the sealed cabinet system, the liquid-cooled Sinamics S120 cabinet modules frequency converter is ideally suited for use in harsh environments. Efficient heat dissipation means there is no need for air conditioning, which markedly reduces energy consumption.


Sinamics S120 cabinet modules frequency converters are part of a modular cabinet system for multi-motor drives. Siemens has extended this portfolio with a view to using it in such specifically harsh environments as in mining or the steel industry, where it makes sense to use a sealed cabinet to protect against chemically aggressive atmospheres. The liquid-cooled Sinamics S120 cabinet modules provides a liquid cooling solution that is fully enclosed in order to protect the frequency converters against hostile ambient conditions. Here, a special cooling technology makes heat dissipation efficient and renders air conditioning unnecessary. Added to this, liquid cooling uses little energy which makes for leveraging additional energy savings potential.
