Single Tube Heat Exchangers


MASH System

The prime design for vacuum air-cooled condensers is based on MASH concept. Steam is brought to the condenser via a 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 go up through a deflegmation row for final condensation.

Answering most of API 661 (ISO 13706) and ASME VIII div 1 requirements

U stamped when required by end user

Optimized selection for plot plan restrictions using Groovy fins

Single Row System
The Single Row system consists of an aluminium coated steel flat tubes. Aluminium fins are brazed to the aluminium coated flat tubes. The solder filling the gap between the foot of the fins and the core tube provides excellent heat transfer properties.

Low Steam Side pressure drop for better vacuum and low condensate sub-cooling

Optimal use of the complete cooling surface as no-flow regions are avoided

Most resistant to freezing

A-Tube System
A-tube consists of an elliptical bare tube with rectangular carbon steel fins. Heat transfer is optimized by hot dip galvanization. The gap between the fin foot and the fin is filled completely with zinc to achieve excellent heat transfer properties.

Hot dip galvanizing provides for outstanding corrosion protection

Suitable for vacuum operation as well as for pressure condensers subject to PED or ASME VIII div 1
