The prime design for Vacuum Air-cooled Condensers is based on MASH© concept. Steam is brought to the condenser via steam duct and a manifold. Steam flows down across 2 or 3 rows of finned tubes. Condensates are recovered inside bonnet header boxers connected to a hot water tank. Non condensable goes up through a deflegmation row for final condensation
Advantages of the MASH system are:
Frames of tube bundles and supporting A frame structure designed for Modular assembly concept and transportation by sea requirements
Over 30 years corrosion resistance using Extruded fins technology.
Answering most of API 661 (ISO 13706) and ASME VIII div 1 requirements
U stamped when required by end user
Round tubes of 2,11 mm core thickness
Optimized selection for plot plan restrictions using Groovy fins
