IKN covers the entire clinker production capacity from 500 t/d to 15,000 t/d without compromising clinker or process quality.

In 2011 and 2012, three Pendulum Coolers® with a capacity of 13,000 t/d each startet operating. The coolers were designed with an intermediate crusher. The total grate size is 303 m². Only 16 fans are required to provide the necessary cooling air. For further information, see press, media and news.

In contrast, IKN supplied a small cooler to a customer in Spain. It has 22 m² of aerated surface and 5 cooling fans, processing a nominal capacity of 900 t/d.
