Liquid cooling in Siemens converters reduces energy consumption

• Efficient heat dissipation in liquid-cooled Sinamics S120 Cabinet Modules makes air conditioning unnecessary
• Footprint smaller than with comparable air-cooled cabinets
• Simple ordering process, installation and implementing thanks to integration into commercially available engineering tools

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 optimized 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.

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.

Heat recovery principles can also be exploited by using the coolant heated up during the cooling process to provide low-cost process heat or room heating.

All individual liquid-cooled Sinamics S120 Cabinet Modules are perfectly compatible, modular, and can be flexibly combined. Additional a wide range of options is available, allowing specific requirements to be accommodated with ease. Factory pre-configuration and integration into commercially available selection and engineering tools, such as the Katalog, PMD and Sizer, make for simple ordering, installing, and commissioning of the system.

Sinamics S120 Cabinet Modules converters are mainly used in process, steel, and automotive industries and in the mining.
