Our products

Product category: Filter technologies (flue gas and electrostatic)


The dry electrostatic precipitators offered by INTERPROJEKT are characterized by a modular design based on five basic modules. Due to that, an optimum adaptation to the respective operating conditions is ensured.

In case of changing conditions or tightening of the regulations an easy and economic extension is possible.

More than 70 installations in Europe.

Mainly as a dry scrubbing with calcium carbonate (lime) as a sorbent for the reduction of SOx, HF and HCl.

In a special designed reaction tower (scrubber), the flue gas is mixed with the sorbent, so that a maximum separation or for a given deposition, a minimum consumption is achieved.

The Reduction of NOx with SCR process (Selective Catalytic Reduction) is usually achieved with ammonium hydroxide as a reducing agent.

With our new patented cleaning process of the catalyst surface, the compressed air consumption is minimized, the pressure drop in the catalyst is reduced, the lifetime of the catalyst is extended and the dust carry over during the cleaning process is minimized
