FAQ
Q: What are the advantages of LNG generators compared to fuel generators?
A: Compared to fuel generators, LNG generators have three core advantages: ① better environmental friendliness: emissions meet the National VI standard, carbon emissions are reduced by more than 70%, there is no black smoke or carbon accumulation, and they are compatible with environmental policies; ② Lower operating costs: LNG fuel prices are stable, reducing diesel costs by 30% to 40%, and the maintenance cycle is long, resulting in lower operation and maintenance costs; ③ Higher safety: LNG combustion has no risk of explosion, and after leakage, it quickly vaporizes and spreads. Its safety far exceeds that of fuel, and there is no oil pollution.
Q: Do LNG storage tanks need to be replaced regularly? Is there a safety risk during storage?
A: LNG storage tanks do not require regular replacement and can have a service life of 8-10 years under normal use. Regular (once a year) testing of the tank's sealing and pressure resistance is sufficient. The safety risk during storage is extremely low: ① The storage tank is made of specialized low-temperature pressure resistant materials with excellent sealing performance, and the LNG volatilization rate is ≤ 0.5%/day; ② Equipped with an automatic overpressure relief device, which automatically releases pressure when the pressure exceeds the standard to avoid damage to the storage tank; ③ After LNG leakage, it will quickly vaporize, with a lower density than air, and will spread upwards, making it less likely to accumulate and cause explosions. Its safety is much higher than that of liquefied gas storage tanks.
Q: Can a 20kW LNG generator meet the production electricity needs of small factories?
A: Absolutely possible! A 20kW LNG generator can meet the basic production electricity needs of small factories and workshops, and can simultaneously drive 2-3 small processing machinery (such as lathes, milling machines), lighting, office equipment, ventilation fans, and other equipment to operate (multiple high-power devices can be turned on at the same time). If the electrical load is large, multiple units can be operated in parallel (up to a maximum of 120kW), fully meeting the production power supply needs of small factories.
Q: Can the equipment start and operate normally in low temperature environments (such as -20 ℃)?
A: Can start and run normally! This series of LNG generators is suitable for a wide temperature range of -20 ℃~50 ℃ (up to -25 ℃ for 20kW/30kW models) and is equipped with a low-temperature starting auxiliary device. Even in a low-temperature environment of -25 ℃, it can be started with one click without additional heating; The LNG vaporizer adopts a low-temperature adaptation design, with stable vaporization efficiency in low-temperature environments, ensuring sufficient gas supply and no fluctuations in equipment operation.
