Rico-Werk Eiserlo & Emmrich Ltd. evolved since 1969 into one of the largest manufacturers of high-voltage DC systems for electrostatic precipitator in Europe. So far, we have built over 12,000 installations, which are in use worldwide.

Our products include the top technology in the supply of high voltage electrical filters.

The removal of dust from flue gases by means of electrostatic precipitators is a way of reducing costs and has proved its value over and over again down the years. Our HV units are used together with electrostatic filters in environments where large volumes of flue gas, dust or process gases need to be purified.

For many years now Rico has had an excellent reputation with its customers for speedy and effective service. Our customer service department guarantees to give your units the best possible service and maintenance. We can also repair and maintain units of other manufacturers competently and carefully. We have all the usual spare parts in stock.
