What is the noise level in decibels of Huaquan’s Máy phát điện im lặng bộ?
When operating at full capacity, the Huaquan silent generator set can produce noise levels as low as below 75 decibel (measured at a distance of 1 meter from the unit), significantly lower than the 90-110 decibels produced by traditional open-type generator sets.
The comparison of noise data at different measurement distances is as follows:
| measurement position | Noise level of Huaquan silent unit | Measurement standard description |
| Tại 1 meter | 75dB(MỘT) | The factory testing standard is equivalent to the volume of normal conversation between two people |
| Tại 7 mét | 65-75dB(MỘT) | Simulate actual usage scenarios to meet urban environmental protection requirements |
| Ordinary open-type unit (Tại 1 meter) | 95-110dB(MỘT) | Equivalent to the sound of an electric saw or firecrackers |
Taking Huaquan Power’s 120kW silent generator set as an example, its noise limit at 1 meter is 75dB(MỘT); trong khi Huaquan Power’s 15kW low-power silent generator set can control noise within 60-65 decibel, making it more suitable for quiet environments such as homes.
- What does 75 decibels mean? What noise level does it belong to?
75 decibels is roughly equivalent to the volume of two people having a normal conversation face-to-face, which meets the requirements of noise-sensitive places such as hospitals, khu dân cư, trường học, và trung tâm dữ liệu.
Daily Noise Comparison Reference Table:
| noise source | Decibel value | Human perception |
| Late-night library | 30dB | Very quiet |
| Normal conversation | 60-75dB | comfortable |
| Huaquan silent generator (Tại 7 mét) | 65-75dB | Acceptable, does not affect conversation |
| Ordinary Máy phát điện Diesel (Tại 1 meter) | 95-110dB | It sounds like an electric saw, unbearable |
| aircraft engine | 110dB+ | Eardrum discomfort |
What does the noise level of Huaquan Power‘s silent generator set signify? It ensures quiet and worry-free operation, whether it’s for emergency surgery in the middle of the night, life monitoring in the ICU, or power supply in residential areas at night.
III. Are the noise levels the same for different power models?
The noise levels of Huaquan silent generator sets with different power levels vary slightly, but they are all controlled below 75 decibel. Nói chung, the lower the power, the lower the noise.
| Unit model/power | noise value | measure distance | Applicable scenarios |
| HQ15GF (15kW small model) | 60-65dB(MỘT) | Tại 1 meter | Household use, small shop |
| HQ120GF (120kW medium-sized) | 75dB(MỘT) | Tại 1 meter | Bệnh viện, tòa nhà văn phòng |
| HQ500GF (500kW large-scale) | 75dB(MỘT) | Tại 1 meter | Trung tâm dữ liệu, factory |
| Conventional models across various power ranges | 65-75dB(MỘT) | Tại 7 mét | General for cities and residential areas |
Ghi chú: The entire series of Huaquan Power’s silent units are designed with a unified noise reduction standard, targeting a noise level of 75dB(MỘT) regardless of power output, ensuring a consistent user experience.
- How does Huaquan silent generator achieve low noise?
Answer: Huaquan Power controls the noise of the generator set below 75 decibels through five major silent black technologies:
- Fully enclosed noise-reducing enclosure
The Huaquan soundproof enclosure is treated with spray painting technology, making it corrosion-resistant and rust-free. The enclosure is made of thickened cold-rolled steel plates that are cut and bent into a solid structure with an attractive appearance.
- Multi-layer sound-absorbing material
The inner wall of the box is filled with 6cm thick sound-absorbing cotton, combined with perforated galvanized soundproof boards, forming a dual noise reduction structure of “bông hút âm + galvanized boards”, which can reduce noise by 30%-40%.
- Maze-style air intake and exhaust sound-absorbing channel
The air intake and exhaust channels are designed with a three-layer blocking labyrinth structure: this ensures the sufficient input of fresh air, effectively cools the unit during operation, and also effectively seals the noise transmission path, achieving “ventilation without sound transmission”.
- High-efficiency filter-type smoke exhaust silencer
The exhaust system is equipped with an industrial-grade resistive muffler, which eliminates the high-frequency “hissing” sound produced when high-temperature and high-pressure exhaust gas is ejected, further reducing exhaust noise.
- Shock absorption design
A rubber automotive shock absorber is installed between the engine and the base, featuring a dual-screw design, effectively reducing vibration transmission and preventing the box from becoming a “large speaker”.
- What are the applicable scenarios for Huaquan silent Máy phát điện?
Huaquan silent generator sets, with their ultra-low noise characteristics, have become the “standard equipment” in the following scenarios:
| Kịch bản ứng dụng | Why choose Huaquan silent unit | Recommended power range |
| Hospital/Operating Room | Emergency surgeries in the middle of the night and ICU monitoring require absolute silence, and the ordinary unit with a noise level of 110dB cannot be used | 100-500kW |
| Residential area/house | Power supply at night does not disturb residents and complies with community noise management regulations | 10-100kW |
| School/library | The teaching environment is sensitive to noise and requires silence | 50-200kW |
| trung tâm dữ liệu | 24-hour uninterrupted power supply requires a low-noise operating environment | 300-1000kW+ |
| Night construction/emergency rescue | There are noise restrictions for urban nighttime operations, and silent units are a compliant choice | 50-300kW |
| Hotel/shopping mall | The business premises need to maintain a comfortable environment | 100-500kW |
| Large-scale event/concert | Ensure power supply without affecting the performance effect | 200-1000kW+ |
Typical reference: Huaquan Power’s 500kW silent generator set has been widely used in hospitals, trung tâm dữ liệu, và các kịch bản khác, with users reporting “it really works well”.
- Noise Comparison between Silent and Ordinary Generator Sets
The noise control advantage of Huaquan silent generator sets is very obvious. The following is a detailed comparison:
| Comparison item | Huaquan silent generator set | Ordinary open-type unit |
| Noise at 1 meter | 75dB(MỘT) | 95-110dB(MỘT) |
| Noise at 7 mét | 65-75dB(MỘT) | 85-100dB(MỘT) |
| Human perception | Normal conversation volume | Similar to the sound of a chainsaw or firecrackers |
| Applicable Environment | Cities, khu dân cư, bệnh viện, trường học | Construction sites, wilderness, factories far away from crowds |
| protective performance | IP23 is rainproof and dustproof, suitable for outdoor placement | A computer room needs to be built for protection |
| price | Relatively high (+20%-30%) | lower |
Key conclusion: The noise of a regular unit is equivalent to the sound of an airplane engine at 110 decibel, whereas the Huaquan silent unit can control the noise to below 75 decibel, which is equivalent to a noise reduction of over 35 decibel. For every 10 decibels increase, the perceived volume by the human ear approximately doubles – this means that the actual auditory loudness of the Huaquan silent unit is only 1/8 ĐẾN 1/4 of that of the regular unit.
VII. How to choose the suitable power for my Huaquan silent generator?
When selecting Huaquan silent generator sets, it is recommended to follow the steps below:
| bước | considerations | Specific suggestions |
| 1 | Total load calculation | List and add up the power of all devices that require simultaneous power supply |
| 2 | Starting current reservation | The starting current of motor-driven equipment (air conditioners/water pumps) là 3-5 times the rated current |
| 3 | biên độ an toàn | The main power of the unit is ≥ 1.2 times the total load |
| 4 | Noise limit assessment | Confirm the daytime/nighttime noise standards for the installation site |
| 5 | Confirmation of installation location | The silent unit only requires a flat floor and does not need to be installed in a machine room |
