⚙️ I. Core power and performance
1.Weichai original engine
Adopting Weichai WP2.3D33E200 four-cylinder diesel engine, equipped with supercharged air intake and direct injection fuel supply system, with rated power of 25kW (standby power of 33kW), mechanical speed control system to ensure that the rotational speed fluctuation rate is ≤4% when the load changes suddenly and the voltage stability is high.
2.Efficient cooling and starting
Closed water-cooling system: adapts to high-temperature environment above 45℃, and supports the use of antifreeze in winter.
12V DC start: equipped with pre-charged battery, supporting more than 6 consecutive starts, with excellent cold start performance.
⚡ II. High efficiency energy saving and environmental protection
1. Low fuel consumption design
Fuel consumption rate ≤ 212 g/kW-h (full load), with direct injection fuel system to optimise combustion efficiency and reduce long-term operating costs.
2.Low emission and noise control
Meet the European emission standards, industrial silencers control the noise at 95dB (LP7m distance), suitable for sensitive environments such as residential areas or hospitals.
🛡️ III. Reliability and Environmental Adaptability
1. Severe environment verification
It has passed the ‘three highs’ test of high altitude, high temperature (45℃) and high cold, adapting to complex working conditions such as mines and plateaus.
2.Electrical stability
Equipped with AVR automatic voltage regulator, voltage fluctuation rate ≤ ± 0.5%, frequency fluctuation rate ≤ ± 0.5%, to ensure the safety of power supply for precision equipment.
3.Rapid response capability
It can be loaded to full load within 1 minute in emergency mode, and supports frequent starting and stopping, which is suitable for fire-fighting backup power supply and other scenarios.
🛠️ Structure and maintenance convenience
1. Compact and lightweight design
The size is about 1700×750×820mm, and the weight is only 400kg, which is convenient for fixed or mobile deployment.
2. Low Maintenance Requirements
Long maintenance cycle: standard maintenance interval of 6500 hours, overhaul period of more than 32000 hours, reducing downtime costs.
Modular components: dry replaceable air filter element and full-flow oil filter simplify daily maintenance.
🏢 V. Application Scenarios and Expandability
Typical use: hospitals, office buildings, factory backup power, mining engineering and fire emergency power supply.
Optional configuration:
Rain-proof canopy/low noise box (adapted to outdoor or residential areas).
ATS automatic switching screen, battery float charger, etc., supporting automation integration.
💎 Summary
With the core advantages of low fuel consumption, high stability and strong environmental adaptability, combined with the long life design (overhaul period of 32,000 hours +) and convenient maintenance, the Weichai 25kW unit has become an ideal choice for small and medium-sized emergency/common use power supply.
