ENMAS O & M -ACC DIVISION (Formerly EFFIMAX AIR COOLED CONDENSERS) is an experienced ACC engineering and supply firm located in Chennai, India. The founders and the engineers have a combined experience of more than 25 years with various multi-national companies in the design and engineering of Air Cooled Condenser.
ENVIRONMENTAL 1. No plume 2. No drift emissions 3. No blow down 4. No water treatment chemicals 4. No leaching of wood preservatives
OPERATIONAL AND MAINTENANCE 1. Lower annual maintenance costs than wet cooling systems 2. No circulating water pump costs 3. No water pretreatment costs 4. No water chemical costs 5. No outages required for maintenance 6. Longer life span than wet cooling systems
1. Steam from the turbine flows under vacuum to the primary fin tube bundles.2. Some steam condenses in the ducting before reaching the primary fin tube bundles, flows into the drain pot and then to the condensate tank by gravity or by pump. 3. 90-95% of the steam condenses in the primary bundles and flows by gravity to the condensate tank. 4. The remaining 5-10% of steam is pulled upward through the secondary tube bundles, condenses and flows by gravity down to the condensate tank. 5. Non-condensable are extracted from the top of the secondary fin tube bundles by pressure drop created by steam ejectors. 6. Non-condensable and residual steam are then processed by the inter and after condenser and condensate flow by gravity to condensate tank, non-condensable are ejected to atm. 7. Main condensate pumps circulate condensate from condensate tank back to the boiler.
EQUIPMENT DESIGN 1. ACC data sheet. 2. Condensate Receiver tank. 3. Steam Jet Air Ejector Data Sheet. 4. Pump data sheet. 5. Line list, Load list, Valve & instrumentation list.
MECHANICAL DESIGN 1. Mechanical including pump, ducting and Structural steel drawings, Wind wall arrangement. 2. Piping, isometrics, pipe spool drawing. 3. Mechanical strength calculations. 4. Equipment requisition packages.
PROJECT MANAGEMENT & PROCUREMENT SERVICES 1. Full control of the execution and delivery of the product. 2. Work with the single sourced vendors to ensure quality and on time delivery.
ERECTION AND COMMISSIONING SERVICES
Complete control of the erection for on time completion and commissioning of ACC.
ENMAS is determined to become its customers' most reliable partner. We understand that On-time delivery of the engineering is imperative to the project schedule. We are dedicated to meeting all customer schedule requirements while maintaining the highest levels of quality in order to eliminate the need to perform on-site rework.
Specific measures undertaken include:
1. Error free in shop detailing by combining the Engineering and shop detailing. 2. Allowing for transportation limitations during the design and engineering stage. 3. Considering construction requirements during the design and engineering stage. 4. Properly checking all engineering drawings prior to Shop engineering to eliminate unnecessary design amendments. 5. Preparing 3D models to ensure fit and interface requirements are met, using state-of-the-art software, compatible with fabrication machinery. 6. Performing interface checks at all scope limit points.
