Open type generator sets, refer to generator sets where the engine and generator are mounted on a rigid metal base frame. Their structure is open, with the main components clearly visible.
I. Characteristics of Open Type Generator Sets
Open type generator sets have an open structure without any outer casing. They are low-cost, have good heat dissipation, and are easy to maintain, but they are very noisy and offer poor protection. They are mainly used in industrial sites and construction sites where noise is not a concern.

The company has become a trusted power solutions provider in industries such as industry, infrastructure, and agriculture.
III. Advantages of Open Type Generator Sets
1. High cost-effectiveness: Open type generator sets have the simplest structure, eliminating the need for an enclosure and complex noise reduction design, making them the most economical choice for the same power level, with low initial investment.
2. Excellent heat dissipation: The open structure allows the engine and generator to release heat quickly and naturally, ensuring high cooling efficiency. This is beneficial for long-term continuous high-load operation and provides good stability.
3. Convenient maintenance: The core components of open type generator sets are clearly visible, making daily inspections, fault diagnosis, maintenance, and repairs easier, saving time and maintenance costs.
4. Direct and efficient power output: The design focuses on power conversion with a compact structure and relatively low power loss, providing more direct electricity output.
5. Lightweight and flexible: Compared to silent or enclosed generator sets of the same power, open type generator sets are lighter and smaller, offering greater flexibility for fixed site installation or integration as a power unit.
Safety Operating Procedures for Open Type Generator Sets
IV. Preparations Before Starting an Open Type Generator Sets
1. Environmental Check: Ensure the unit is installed in a flat, solid, well-ventilated outdoor area or designated site, away from flammable and explosive materials, with no debris within 1 meter around it.
2.Open Type Generator Sets Inspection:
- Fasteners: Check that the base, engine, generator, and other connected parts are secure.
- Fuel System: Check that the diesel/gasoline level in the open type generator sets is sufficient and that the fuel lines have no leaks.
- Cooling System: Check that the coolant level is normal and that the radiator is not blocked.
- Lubrication System: Ensure the engine oil level is within the normal range on the dipstick.
- Electrical System: Check that the battery of the open type generator set is fully charged, wiring is secure with no exposed parts, and the output circuit breaker is in the "OFF" position.
- Protective Devices: Ensure that protective covers for rotating parts (such as belts and fans) are intact and securely in place.
V. Precautions for Starting and Operating Open Type Generator Sets
1. Personal Protection: Operators should wear work clothes, insulated gloves, and safety shoes; long hair must be tied up. It is strictly forbidden to touch rotating parts with gloves.
2. Precautions for Starting Open Type Generator Sets:
No-Load Start: Ensure there are no connected loads before starting.
After starting, run under no-load conditions for 3-5 minutes, and observe whether the oil pressure, voltage, and frequency are stable and normal, and check for any abnormal noises, severe vibrations, or oil leaks.
3. Monitoring the Operation of Open Type Generator Sets:
It is strictly forbidden to disassemble or adjust parts of the generator set while it is running.
Closely monitor the instruments (voltage, frequency, current, oil pressure, water temperature) to ensure they are within rated ranges.
Pay attention to sounds and exhaust smoke; if abnormalities are detected (such as unstable speed, unusual noises, or thick smoke), stop the machine immediately for inspection.
It is strictly forbidden to add fuel or coolant while the open type generator set is running.
Keep your body, clothing, and tools away from high-temperature parts (exhaust pipe, muffler) and rotating components.
VI. Precautions for Shutdown and Load Connection of Open Type Generator Sets
1. Normal Shutdown:
Gradually unload all loads first, allowing the open type generator sets to run idle for 3-5 minutes to cool down.
Turn off the start switch and remove the key.
Close the fuel valve (if equipped).
Emergency Shutdown:
In case of an emergency, immediately press the emergency stop button or close the throttle.
Connecting Load:
Electrical connections or maintenance must only be performed after the open type generator set has completely stopped.
The total load power must not exceed the rated power of the generator.
Follow the principle of "connect high-power loads first, then low-power loads" to avoid sudden application of excessive load.
Of course, there are many other safety operating procedures for open type generator set, and specific details should be referred to in the relevant operation manual.
VII. Q&A on Open Type Generator Sets
1. How to determine the power when purchasing an open type generator sets?
Calculate the total starting power of all loads and leave a 20%-30% margin.
2. Can an open type generator set be used indoors?
It is strictly forbidden to use it in enclosed or poorly ventilated indoor spaces, as this can lead to toxic exhaust gas accumulation and poor heat dissipation. If indoor use is necessary, a strong ventilation system should be installed, and the generator should be kept away from flammable materials.
3. How to properly connect loads to an open type generator set?
Connect cables while the generator is turned off.
The total load power should not exceed the rated power.
Follow the loading sequence of "large first, small later" to avoid sudden full-load addition.
VIII.. Application Areas of Open Type Generator Sets
1. Construction sites: Provide temporary power for construction equipment and lighting.
2. Factory backup power: Emergency start during power outages to ensure production.
3. Agricultural irrigation and farming: Supply power to water pumps, feed processing, and other equipment.
4. Mines and oil fields: Provide reliable power in remote outdoor locations.
5. Equipment rental: Used for temporary power supply during large events or emergency rescue operations.
6. Integrated power units: Serve as the core power source for equipment such as air compressors and fire pumps.
Open type generator sets feature simple structure, low cost, good heat dissipation, and easy maintenance. Users should choose the appropriate open type generator sets based on specific work requirements.
