150kW Water Cooled Automatic Start Diesel Generator Emergency Standby Power Generator

This rated 150kW (187.5kVA) mobile trailer‑mounted silent diesel generator set delivers reliable emergency standby power. Fitted with water‑cooled industrial diesel engine, full‑copper brushless alternator, integrated silent sound‑proof canopy and heavy‑duty mobile trailer chassis, it adopts 50Hz, 3‑phase 4‑wire power output. With auto‑start function and optional ATS automatic transfer switch, the unit conforms to ISO 8528 international standards. It is widely used for construction sites, municipal engineering, field camps, temporary projects and noise‑sensitive outdoor locations requiring movable backup power.

• Water‑Cooled Industrial Diesel Engine
  4‑stroke water‑cooled turbocharged intercooled industrial engine with sufficient power reserve, low fuel consumption and excellent performance under high‑temperature and dusty outdoor conditions. Standard 24V DC electric auto‑start system ensures fast response when mains power fails.
• 3‑Phase 4‑Wire Full‑Copper Brushless Alternator
  Class H insulation, IP23 protection grade, low voltage waveform distortion. Rated 400/230V 50Hz three‑phase four‑wire output, compatible with mixed three‑phase equipment and single‑phase loads, providing stable clean power to protect motors, lighting and precision devices against voltage fluctuation damage.
• Silent Sound‑Proof Canopy
  Fully sealed rain‑proof, dust‑proof anti‑corrosion steel canopy with multi‑layer high‑density sound‑absorbing cotton and large industrial silencer. Noise ≤74dB(A) @7 m. Optimized independent air‑intake and exhaust duct prevents overheating during long‑time continuous outdoor running.
• Heavy‑Duty Mobile Trailer Chassis
  Two‑wheel heavy‑load towing trailer equipped with leaf‑spring shock absorption, mechanical parking brake and adjustable leveling support legs. Convenient to be towed by engineering vehicles for rapid relocation between different working sites. Anti‑slip mounting base avoids unit displacement under heavy‑load operation.
• Auto‑Start Control & Full Safety Protection
  Intelligent digital controller real‑time displays voltage, current, frequency, coolant temperature, lube oil pressure, rotation speed and running hours. Auto‑start trigger when grid power is lost. Complete protection against overspeed, high water temperature, low oil pressure, overvoltage, undervoltage, overload and short‑circuit, with sound‑light alarm and automatic emergency shutdown. Optional ATS cabinet realizes fully unattended automatic power switching between mains and generator.
• Integrated Base Frame
  Thick channel‑steel welded base with built‑in daily fuel tank. High‑density rubber shock absorbers reduce vibration transmission. Reserved interface for external large‑capacity fuel tank supports long‑hour unattended operation.

• Combined silent canopy and mobile trailer design, meets noise‑limit requirements and enables flexible on‑site transfer for temporary projects.
• 3‑phase 4‑wire rated output adapts various industrial and commercial mixed‑load working conditions.
• Auto‑start function plus optional ATS supports unattended emergency backup power supply.
• Water‑cooled power unit guarantees stable continuous heavy‑load operation for harsh outdoor environments.
• Pre‑assembled complete unit, simple commissioning after transportation, ready for quick deployment.
• Multiple safety protection mechanisms extend unit service life and lower maintenance risks.

Urban municipal construction sites, road engineering, field operation camps, temporary commercial events, mining sites, disaster rescue, remote project locations and other places requiring movable silent emergency standby power.
