Surface Condensers

The Steam Surface condenser is a critical component of both the traditional coal fired power plant and the new generation cogeneration and combined cycle power plants. AAHANA has manufactured more than 500 nos of Surface Condensers. The largest Condenser supplied by AAHANA Giffard systems is with surface area of 3800 m2 and of 160 TPH steam flow.

Main duties of any Surface Condenser are to convert the exhaust steam from its gaseous to its liquid state at certain under atmospheric pressure, and also, to release non-condensable presented in the steam cycle, together with vacuum unit.

AAHANA Giffard systems designs and economically sized condenser suitable for smaller turbine ratings under 100 MW. The circular configuration is compact for easy shipping and maintains the level of quality afforded all of our condenser designs.

All of AAHANA’s Surface Condensers are designed and built to the Heat Exchange Institute latest Standards. We also strive to meet all of our client’s project specific requirements.

Our Condenser design can incorporate enhanced deaeration systems, and or a variety of turbine exhaust options including Axial and top steam inlet design, which can assist greatly in improving plant layouts. We continually address and refine these and other considerations associated with circular designs where space is at a premium.

AAHANA Surface Condensers are fabricated in-house state of the art fabrication facilities located in India and Germany. All of the fabrication facilities are according to ASME code and an impeccable reputation for quality fabrication and on time delivery.

Our Surface Condensers feature high overall heat transfer coefficient (which result in smaller heat transfer areas and thus optimal use of the available space) and extremely low oxygen concentrations in the condensate. They are designed to stand up to turbine and steam generator overloads and to variations in cooling water temperature at different times of the year.
