Design process.
Kohsel ensures high quality through a constant focus on safety, cutting-edge production methods and training. Final control focuses especially on the critical tolerances that are important for the customer.
External reactors, chokes and filters
Line reactors
Reduce low frequency interference (harmonics) and relieve the strain on the grid network by compensating for the distortion reactive power induced.
Harmonic filters
Reduce current harmonics (THDi) to comply with the limit values required under the standards. This protects the connected grid network from circuit feedback and increases the system immunity from interference. Our LCL filters are specially designed to reduce harmonics of current absorbed by the rectifiers in the input converter.
Motor chokes
Reduce the voltage rise and the voltage spikes between the conductors which become more pronounced as cable length increases.
dV/dt filters
Protect motors against high voltage increases and voltage peaks at the motor terminal.
Sinus filters
Effectively protect the motor insulation and reduce supplementary losses and noise emissions from the motor. All-pole sine filters also enable the use of unshielded motor lines.

Our certificates
Kohsel is committed to providing customers with the highest-quality products, but also aspires to the highest standards of social responsibility and ethical conduct. Our core values support a strong commitment to economic, environmental and socially sustainable development.
Our journey started back in 1969. More specifically at Skovvænget 7 in a town near Aarhus down in Poul-Erik Kohsel and his wife Hanne’s basement. This was where it all began. Soon after that the basement was replaced with a factory nearby. Years after new markets were conquered, new factories in Europe and Asia were built and many people have been employed since then.
