Claudius Peters Clinker Cooler - ETA Cooler

After 50 years of experience with conventional grate coolers Claudius Peters developed a modern and future-oriented machine to overcome all disadvantages of older clinker cooler technologies. 
The Claudius Peters ETA cooler represents the 5th Generation of Clinker Coolers. 

It is worldwide the most advanced clinker cooler reaching clinker capacities from 500 t/d to 13 000 t/d. 

The ETA cooler consists of an HE-module (static inlet) in the kiln drop zone and standard units with horizontal arranged lanes, and enables operation with a higher clinker bed than conventional clinker coolers. This improves the function of the heat exchanger and generates a significantly higher degree of efficiency than with conventional grate coolers and beam coolers.

Claudius Peters offers
Flat Coolers – with the Hammer/Roller Crusher at the end
Stage Coolers - with intermediate Roller Crusher

The compact design fits perfectly for both Greenfield projects as well as cooler replacements for wet and dry kiln systems. The ETA cooler is particularly suitable for the use of Waste Heat Recovery(WHR-) systems and recirculation (i.e. Duotherm-) Systems.
 Due to the high degree of efficiency and the associated high and stable recuperation temperature due to the high clinker bed, the ETA cooler is particularly suitable for the sustainable use of alternative fuels (secondary fuels) and supports an increasing replacement of primary energy sources.

Since 2004 the ETA clinker cooler technology has proven its unique process excellence with all leading cement producers.

HE Module

Claudius Peters supplies all his coolers since years with a static grate in the inlet zone of the clinker cooler, the so-called HE module. In recent years, the HE module has been developed to achieve a long service life with low-pressure losses, reducing operating costs to a minimum.
