Our Quality & Service Commitment.

What every JIUAN unit delivers — before and after it reaches your site.

Extended warranty, PICC-backed

Up to 2 years or 2,000 hours of full-unit warranty (whichever comes first), underwritten with PICC (People’s Insurance Company of China). The freight forwarder’s insurance policy is available for your reference. OEM extended cover: up to 3 years on Perkins engines and 2 years on Stamford S-series alternators.

3–5 day global parts express

Guaranteed expedited air shipping: core warranty components arrive anywhere in the world in just 3 to 5 days, keeping your downtime to a minimum.

100% new & individually traceable

Every unit is brand new with a unique ESN (Engine Serial Number). Each generator undergoes staged load tests at 0%–25%–50%–75%–100% and 110% overload before shipment — the test video and PDF load analysis report are delivered with every unit.

Heavy-duty canopy engineering

Soundproof canopies use cold-rolled steel ≥ 2.0 mm, finished with 120°C electrostatic high-gloss powder coating for outstanding rust and scratch resistance. High-density flame-retardant rock wool (40 kg/m³) keeps noise down to 65–68 dB at 7 m.

Ready for extreme environments

Cold-region kit: engine jacket water heater, fuel heater and automatic louver system for Siberia and Northern Europe. Coastal kit: C5-M grade anti-corrosion painting for salt-mist islands and offshore sites.

Support that lowers every barrier

Free service wrench & testing meters; a 150-page maintenance manual in 5 languages (CN/EN/ES/FR/RU) with wiring diagrams and 3D disassembly animation; 3D exploded views & anti-counterfeit close-ups for CAD-like inspection; and one-stop customs clearance certificate service.
