RELIABLE POWER GENERATION
SDEC was founded in 1947 and is a diesel engine manufacturer. They are ISO9001, QS9000 and TS16949 certified, which is testament to their quality and reliability.
GENERAL SPECIFICATIONS
SDEC 405kW Diesel Engine
High Torque and Rapid Load Recovery
The SDEC 6ETAA12.8-G21 engine uses a 12.8L inline 6-cylinder layout equipped with an advanced twin turbocharger and a high capacity air-to-air intercooler. This forces cool air into the engine efficiently, allowing it to recover its power immediately when large machinery or commercial systems switch on. This ensures stable frequency control for operations that cannot tolerate voltage dips.
Built for Tough Local Conditions
Engineered to withstand demanding operational environments, this engine features a dry-liner block design and a 24V electrical system for reliable starting. It includes a large 36-litre oil sump for effective internal cooling and a 1000mm blower fan to keep running temperatures stable during extended power cuts. These features ensure long term mechanical reliability across South African industrial zones and remote facilities.
Robust Construction and 4-Valve Efficiency
Built with a high strength cast iron block and an integrated cylinder head, this engine uses premium international components to handle demanding large scale workloads. Its 4-valve design improves fuel mixing and delivers steady torque, making it a reliable choice for local generator builders and engineers powering commercial, agricultural, and industrial infrastructure.
Simplified Layout for Easier Maintenance
The engine is designed with fewer individual parts, reducing mechanical complexity compared to standard large engines. This straightforward layout keeps field servicing simple, lowers your long term spare parts costs, and ensures maximum uptime under harsh African conditions.
Key Technical Features
Efficient 4-Valve Layout: The robust cylinder block and integrated head improve thermal efficiency and extend the engine's service life.
Precision Manufacturing: Produced under strict SAIC Motor quality controls and verified by world class German automotive production standards for excellent consistency and performance.
Fewer Moving Parts: Uses integrated components to cut down the total part count, making routine servicing simpler and reducing operational costs.
All-Weather Starting: Starts up instantly without a pre-heater in temperatures down to -10°C, and handles extreme cold down to -30°C when paired with an auxiliary heating device.
Clean and Efficient: Meets Off-Road Stage II emission standards, ensuring a cleaner fuel burn and highly efficient fuel consumption.
