Project: Replacement of existing process evaporator unit
Objective
CITAL was selected to engineer, manufacture, and supply a custom process evaporator for a major chemical production site in northern Italy. The unit was designed to replace an existing exchanger operating in critical process conditions, ensuring thermal stability, chemical resistance, and mechanical robustness over time.
