200 KW Trailer Generator
The MST 200 kW trailer generator set is a highly integrated mobile diesel power station, developed and manufactured in strict accordance with international standards. It combines a diesel engine, a brushless alternator, a heavy-duty trailer chassis, a control cabinet, and an enclosure into a single unit, specifically designed for applications such as temporary power supply, off-grid power generation, and emergency backup power.
This 200kw trailer mounted generator set delivers a prime power rating of 200kW, suitable for continuous operation with variable loads, and offers a standby power rating of 220kW to meet short-term emergency peak load demands. Designed specifically for frequent relocation, the unit eliminates the need for fixed installation or the construction of a dedicated generator room. Once towed to the site, operators simply connect the output cables to begin power generation, significantly reducing deployment time at remote work sites.
Engine Brands
Available engine brands include Weichai, Yuchai, SDEC, Cummins, and Ricardo. The unit supports 50Hz/60Hz frequencies and 400V/230V three-phase output. The control system supports both manual and automatic operation modes, with optional upgrades available for an Automatic Transfer Switch (ATS) and a load-sharing/synchronization panel for multi-unit parallel operation.
Key Advantages
Highly mobile and rugged trailer chassis
The MST 200 kW trailer generator comes with a heavy‑duty reinforced steel frame, leaf‑spring suspension, mechanical brake assembly, safety chains and parking hand brake. Fitted with a jockey wheel plus stabilizer support legs, the unit stays level even when set up on uneven ground. Multi‑point vibration dampers separate the power assembly from the trailer frame, shielding the engine and key alternator components from damage while travelling over rough, un‑paved road surfaces.
Rainproof, Dustproof, and Corrosion‑Resistant
Trailer type generators mostly serve open‑air worksites including construction zones, mine sites, and disaster‑response or outdoor event locations. This model uses a sealed protective canopy paired with purpose‑built air intake ducting to keep out dust and flying debris. Circuit leakage protection and fully sealed component housing further help lengthen the service life of vital internal parts.
Working ambient temperature spans ‑20°C up to +50°C.
It supports high‑altitude deployment; power derating is required for sites above 1,000 meters elevation.
Anti rust paint is applied to both chassis and canopy, so the unit holds up well in humid, coastal and mining‑site conditions.
Continuous Operation Performance and Fuel Tank Configuration
The base features a built-in, high-capacity integrated fuel tank, enabling ≥8 hours of continuous full-load operation without the need for an external tank.
Measured fuel consumption data:
Full load: Approx. 205–220 g/kWh
75% partial load: Approx. 190–205 g/kWh
Noise Performance and Optional Sound-Attenuating Enclosure
Standard open-type trailer-mounted units produce noise levels of 82–88 dB. MST offer an optional integrated sound-attenuating enclosure upgrade. With the enclosure installed, noise levels are reduced to 72–76 dB, meeting strict noise control requirements for applications such as nighttime urban construction, outdoor events, and projects near residential areas.
Intelligent Monitoring and Expandable Electrical Features
The standard digital controller enables real-time monitoring of voltage, current, frequency, coolant temperature, oil pressure, and operating hours. In the event of faults such as overvoltage, undervoltage, overcurrent, overspeed, low oil pressure, or high temperature, the system triggers an alarm and initiates a protective shutdown to prevent equipment damage.
Manufacturing Capabilities
MST is a China-based generator set manufacturer with over 25 years of industry experience. We handle our own R&D, assembly, and comprehensive unit testing, rather than acting merely as a reseller. Every generator set undergoes no-load and full-load burn-in testing before leaving the factory to ensure compliance with international manufacturing standards.
Export Experience
Our products have been exported to over 110 countries and regions across Asia, Africa, Europe, and Latin America.
Our team provides comprehensive support, covering everything from pre-sales load analysis, customized configurations, and production progress tracking to post-shipment technical guidance. For overseas projects, we can tailor unit specifications-such as voltage, frequency, and protection settings-to meet local market requirements.
FAQ
Q1: What is the difference between the prime power and standby power of this 200 kW trailer generator?
A: The 200 kW figure is the prime power rating, built for long‑run continuous operation under varying loads. Its standby power hits 220 kW, which is reserved solely for short‑term emergency peak loads and cannot sustain round‑the‑clock 24‑hour running.
Q2: Can this trailer‑mounted generator set run continuously for 24 hours a day?
A: It can run 24‑hour non‑stop as long as it works within prime‑power load limits. Stick to scheduled hourly maintenance: replace engine oil and corresponding filter parts every 250 working hours. For high‑dust locations like mines and construction sites, carry out frequent checks and timely replacement of the air filter.
Q3: Can I tow this generator on public highways?
A: The trailer receives factory reinforcement. It works right away for on‑site towing inside construction compounds or factory yards. If you plan to haul it over public roads, you need to follow local traffic rules for heavy‑duty trailers. This covers formal registration, plus ensuring lights and brake systems satisfy your national regulatory standards.
Q4: How long can the built‑in fuel tank support operation at full load?
A: The standard base‑mounted integrated fuel tank delivers no less than 8 hours of runtime under full‑load conditions. For longer unattended running cycles, we can fit larger custom fuel tanks or add ports to hook up external fuel tanks.
Q5: Is a sound‑attenuated enclosure (silent canopy) available as an option for this trailer‑mounted unit?
A: Yes. We supply trailer generators pre‑fitted with sound‑attenuated canopies straight from the factory. Once fitted, noise output drops to 72‑76 dB, well suited for job sites enforcing strict noise limits.
Q6: What after‑sales support does MST provide to overseas buyers?
A: Full operation manuals, spare‑part checklists and factory test reports come with every unit. Our technical team delivers online support worldwide. Spare parts may ship alongside the genset or be sent in separate consignments. Our partner service network spreads across over 110 export countries to deliver local on‑site assistance.
