Exclusively developed to handle light commercial backup configurations and premium residential estate systems, the Baudouin 25kW Diesel Engine 4M06G25/5 is a highly responsive 2.3L inline 4-cylinder G-Drive plant. Emerging from Moteurs Baudouin’s legendary high-performance PowerKit platform, this liquid-cooled four-cylinder block is meticulously structured to serve as the mechanical heart for 25kVA prime to 28kVA standby generating sets. By combining a naturally aspirated induction pathway with a compact inline engine footprint, this design delivers smooth torque progression and maintains stable frequency curves during sudden block load connections.

Achieving a highly dependable maximum standby output of 25kW at 1500 RPM, this low-displacement model handles steep inductive load variances without hunting. It features a rugged inline layout, a reliable 12V single-battery electrical installation, and an advanced electronic governor. This setup guarantees prompt engine starts and absolute structural reliability under the demanding ambient heat variations and high-dust thresholds characteristic of South African commercial yards and broader regional African infrastructure grids.

LiFeTIDE supports this versatile assembly with deep technical support, readily available warehouse stock, and prompt cross-border distribution.

LEADING GENERATOR MANUFACTURER

For over 100 years, Baudouin has designed and manufactured the highest quality diesel engines for marine and power generation applications globally

GENERAL SPECIFICATIONS

SDEC 25kW Diesel Engine

The Baudouin 4M06G25/5 highlights exceptional engineering balance, utilising a vertical inline four-cylinder layout with a 17.5:1 compression ratio optimised for highly efficient thermal profiles. The core engine architecture incorporates premium cylinder geometry alongside an 8-valve configuration to secure rapid volumetric air exchange. This robust cast-iron block features cross-flow cylinder head structures that isolate extreme structural loading points, effectively preventing head warping and maximising long-term field availability.

Industrial Power Architecture & Reliability

Designed with an integrated cylinder head and a high strength cast-iron block, the 4M06G25/5 utilises premier international component brands to ensure absolute mechanical integrity under rigorous load cycles. Its advanced layout guarantees optimal fuel atomisation and torque delivery, making it the preferred choice for local generator builders requiring reliable prime and standby power for commercial, agricultural, and residential infrastructure. With a simplified layout that drastically reduces part-count complexity, this engine lowers long-term operational overhead while maximising field uptime under demanding African environmental conditions.

Baudouin 25kWm Engine Technical Features

  • Marine-Grade Quality Infrastructure: Engineered backed by Baudouin's 100-year maritime heritage, ensuring extreme structural longevity, robust block thickness, and reliable continuous load-carrying capabilities.

  • Precise Governing Framework: Equipped with a highly sensitive electronic governor that complies with strict ISO 8528-5 Class G3 standards, providing an ultra-stable steady-state speed stability window of 0.5% or less.

  • Simplified Mechanical Framework: The structural blueprint relies on integrated components, reducing total part count compared to conventional diesel powertrains. This results in simplified field maintenance and lower spare parts overhead.

  • Strong Environmental Resilience: Engineered for instantaneous starting capability without an auxiliary device down to minus 5°C, and extending down to minus 15°C utilizing a water jacket heater for absolute grid-independence in cold regional climates.

  • Optimized Thermal Cooling Matrix: Features a mechanical radiator assembly with a belt-driven pusher fan designed for ambient operating temperatures up to 50°C, preventing thermal fatigue during intense high-load South African summer runs.
