Main Technical Features Of This 50 Kw Diesel Generator For Sale
When you look for a 50 kw diesel generator for sale, you want a heavy-duty machine that works well under pressure. Our generator uses a high-performance 4BTA3.9-G2 engine. This is an In-Line 4-cylinder, 4-stroke engine with an electronic governor. The electronic governor is very useful because it controls the engine speed automatically, making sure the power output stays smooth even when your load changes suddenly.
The engine design focuses on long working hours and low maintenance. Here are the main features of the engine system:
- Closed-Circuit Cooling: The cast alloy aluminum fan keeps the engine temperature safe even when the outside weather reaches 40°C.
- Low Fuel Consumption: It only burns 14.1 liters of fuel per hour under 100% load, which helps you save a lot of running costs.
- DC 12V Electronic Start: The reliable battery starting system ensures the generator can turn on quickly within seconds during cold weather.
- High Compression Ratio: The 18.0:1 compression ratio makes sure the diesel fuel burns completely to give you maximum power.

Electrical Advantages Of Our 50 Kw Generator 3 Phase System
For industrial equipment, electricity must be balanced and stable. A 50 kw generator 3 phase system is much better than single-phase systems because it can start large electric motors easily. Our generator offers flexible voltage options such as 220/380V, 230/400V, and 240/415V. This means it can match different electrical standards in different countries perfectly.
The alternator inside our genset uses top-quality materials to ensure safety and durability. You can see its technical advantages from the following points:
- 100% Copper Winding: We use pure copper with a 2/3 pitch design to prevent overheating and reduce electrical loss.
- Brushless Exciter Type: There are no carbon brushes inside, so you do not need to replace parts frequently, saving your time and energy.
- Steady-State Voltage Regulation: The voltage variation is less than ≤1%, which is clean enough to protect sensitive computers.
- Low Total Harmonic Distortion: The distortion is less than 5% on load, which ensures your machines run quietly and smoothly.

Working Limits And Environmental Adaptability
A good generator must work well in tough environments. Our 50kw generator for sale is built to handle difficult outdoor conditions. It can operate at an altitude of up to 1000 meters without losing its output power. The body frame is made of thick steel, and the alternator has an IP21/IP23 protection grade with Class H insulation. This protects the internal electrical parts from dust and water drops.
Whether you need it for daily continuous power or as an emergency backup unit, this genset can handle the job. It also has a sustained short-circuit current capability of 300% for 10 seconds, which means it will not shut down immediately if there is a brief electrical problem in your factory lines.
