Breaking the power gap between mini 30kW and large‑scale 100kW units, the JT‑50KW with 50kW prime + 10% overload (55kW) perfectly matches mixed‑load demands of schools, rural hospitals and agricultural bases. It stably drives lighting, water pumps, air‑conditioning and office equipment simultaneously, avoiding insufficient power of small generators and idle waste of large models, becoming the exclusive power solution for public infrastructure projects.
Different from small‑displacement mini engines prone to heat decay under long‑term mixed loads, the Weichai WP4D66E200 large‑displacement four‑cylinder engine has excellent heat dissipation and load‑bearing capacity. With 340 N·m peak torque, it stably outputs power under long‑term alternating loads of agricultural irrigation pumps and public facility electrical equipment, solving the pain point of unstable power of small generators in long‑run public projects.
The 180L built‑in fuel tank supports 24‑hour non‑stop operation under standard 75% load, fully covering day‑and‑night power needs of remote villages and off‑grid agricultural bases. It eliminates frequent refueling troubles caused by inconvenient fuel transportation in rural areas, realizing unattended all‑day power supply for remote public welfare and agricultural projects.
Verified by Weichai official data, the full‑load fuel consumption is as low as 194‑202 g/kW·h, far below the industry average of same‑power generators. For schools, hospitals and rural facilities with fixed public budgets, this low‑fuel‑consumption design greatly reduces annual operating expenditure, improving project long‑term economic benefits.
Optimized with integrated sound‑absorbing structure, the noise level is strictly controlled at 64‑66dB(A). It fully complies with noise limit standards of school campuses, hospital wards and residential villages, avoiding noise complaints and environmental violations, and can operate safely and continuously in public welfare scenarios with strict environmental requirements.
Equipped with industrial LCD panel and DTC fault diagnosis function, it supports real‑time data monitoring and early warning; matched with standard ATS interface, it realizes automatic power switching during power outage without manual operation. It solves the problem of insufficient professional maintenance personnel in rural public facilities, ensuring stable emergency power supply for key public places such as hospitals and schools.
