The invention of the Maerz PFR kiln process was a big step towards increasing the efficiency of the lime burning process. With an efficiency of 85 % of the heat energy used, the PFR process is still unbeaten today. We have continuously developed our PFR kilns based on our experience and technical innovations and offer this kiln in two series.
