Air Cooled Condenser ACX
The ACX Air Cooled Condenser offers a standardised and modular design leading to short quotation and delivery times, a short payback period and lower CAPEX. The modular design allows for a high degree of preassembly of materials in the workshop and / or at grade level on site which leads to reduction of site erection hours.
Choose from three different fan diameters, 24 ft, 28 ft and 32 ft and combine up to four modules to an Air Cooled Condenser Bay to cover the range of heat flow rejected between approximately 15 MW up to approximately 90 MW. The optimised V-Shape installation with induced draft air fan on top allows for a lower substructure and therefore for a lower overall height as well as reduced power consumption compared with classical A-frame configurations. The mechanical drive (motor + gearbox) is located at the lower platform to ease access and maintenance during operations.
- Modular & compact design
- Up to 20% less power consumption
- 30% less structural steel
- 20% less erection work
Air Cooled Condenser A-Frame
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
- Optimised 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 optimised 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 galvanising provides for outstanding corrosion protection
- Suitable for vacuum operation as well as for pressure condensers subject to PED or ASME VIII div 1
