Automation and control

Stable sludge drying

CORE-DDRY automatically adjusts steam, load level and rotor conditions to stabilize moisture in sludge drying. It reduces process fluctuations, improves energy efficiency and keeps end-product quality consistent even with changing sludge characteristics.
