E-4103 Process Evaporator – Chemical Sector (Italy) 2024

Sector: Chemical
Client: Confidential
Country: Italy
Year of Delivery: 2024
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.
