A family business with a long tradition, looking back on 210 years of history that started in the textile industry.

The entrepreneurial Krawinkel family has created seven generations of traditional manufacturing, innovative technology and constantly fresh ideas.

After many years of experience and success selling electronic light advertizing, PWM introduced as first manufacturer worldwide a new generation of price displays for fuel stations – featuring the electronic input of data.

Since this invention hit the market in 1984, PWM grew into the world market leader for electronic price displays, today active in more than 100 countries.

Innovation remains the motor of the success, while PWM turned the price display into a lighthouse bringing travellers to the fuel station. Today PWM is aiming to be a part of the future of individual mobility.
