Introduction
For facilities that depend on continuous power, the ability to see exactly how a generator set is performing—in real time and through detailed logs—has become as important as the raw output rating printed on the nameplate. Guangdong Minlong Electrical Equipment Co., Ltd., operating under the brand Minlong Power, positions itself as a manufacturer and supplier of diesel generator sets specializing in Cummins-powered solutions for global power needs. Headquartered at No.2 Wenhai Bridge, Baichen Road, Chencun Town, Shunde District, Foshan City, China, the company builds its product matrix around brand new, strictly factory-tested power units that combine internationally recognized engine brands with high-quality alternators such as Stamford, Leroy-Somer, and GZSTF.
Visualized Operating Data: Turning Monitoring Into Actionable Insight
A defining feature across several models in the Minlong Power lineup is the presence of controllers that transform raw engine and alternator performance into clear, readable data. The MLC25 (110/220V Single Phase Edition) is built around the DeepSea DSE6120 controller, which offers a graphic back-lit LCD for measurement and event logging, giving operators operational transparency into how the unit is running at any given moment. This is paired with +/-1% voltage regulation precision, described in the knowledge base as [High Precision], allowing operators to trust that what the display shows reflects tightly controlled output.
On the three-phase side, the MLC30 Diesel Generator Set integrates a SmartGen HGM6120 Controller, which combines digital and analog inputs for comprehensive protection, supporting system safety through continuous monitoring. Together, these controller platforms illustrate how Minlong Power approaches data visualization: not as a decorative add-on, but as a functional layer that lets facility managers verify stable output, track event logs, and confirm that protective thresholds are being respected during operation.
Cummins Engine Platform Across the MLC Series
The backbone of the company's technology platform is the integration of Cummins diesel engines with either SmartGen or DeepSea control systems, supporting dual-frequency operation (50Hz/60Hz), power factors ranging from 0.8 to 1.0, and high efficiency (≥95%) alternators. This engine-and-controller pairing recurs throughout the product line in different configurations tailored to specific power bands and regional voltage standards.
The MLC25 (400V Three Phase Edition) uses the Cummins 4B3.9-G11 naturally aspirated engine for an 18kW-20kW entry-level three-phase solution, described as supporting [Engine Efficiency] through low-maintenance operation. Its Weifu A pump/RSV Fuel System provides mechanical fuel delivery for reliability in varying fuel qualities, while an IP34 ingress protection enclosure guards against water splashes for outdoor durability.
Moving up the range, the MLC30 Diesel Generator Set (22kW-24kW, 50/60Hz) relies on the Cummins 4B3.9-G2 engine, a turbocharged and after-cooled 3.9L unit delivering high power density, housed in a corrosion resistant base frame for long service life in harsh environments. The MLC40 (36kW Edition) is a 60Hz-specific unit built on the 4BT3.9-G2 engine, offering [Enhanced Protection] via an IP44 enclosure rating and an 80L base fuel tank, while its GZSTF STF36-1-4 Alternator delivers industrial grade performance at IP23 protection. The companion MLC40 (32kW Edition) is optimized for 50Hz operation, pairing a Stamford S1L2-K1 Alternator for operational stability with a 220L base fuel tank for reduced refueling frequency.
The MLC60 Diesel Generator Set, rated at 60kW, features the Leroy-Somer TAL-A44-E alternator with SHUNT excitation, described as [Premium Alternator] for superior transient response, backed by the Cummins 4BTA3.9-G2 engine and an IP44 enclosure. The MLC64 Diesel Generator Set (64kW) adds a 4-pole Automatic Transfer Switch for immediate backup during power failure, along with a BYC PB/Electronic Governor for frequency stability.
Further along the range, the MLC65 Diesel Generator Set (52kW, 230/400V, 50Hz) uses a pressurized water air-cooled aspiration system, noted as [Efficient Cooling], with a 110L base fuel tank balancing footprint and runtime. The MLC80 Diesel Generator Set (64kW, 50Hz) is powered by the Cummins 4BTA3.9-G11, paired with a Stamford UCI 224G Alternator recognized for standard-setting efficiency. The MLC90 Diesel Generator Set (64kW-72kW) extends operational endurance with a 1200L base fuel tank, described as [Extended Operation] supporting long-term remote operation without attendance, powered by the turbocharged and aftercooled 4BTA3.9-G11 engine.
At the higher end, the MLC110 Diesel Generator Set (80kW, 50Hz) uses a Stamford UCI 274C Alternator rated at 100kVA for heavy industrial load support, with mechanical governing for ease of maintenance. The MLC115 Diesel Generator Set (96kW-110kW) is powered by the Cummins 6BTA5.9-G2 and offers [Environmental Adaptation] through specialized power-derating curves for altitude (>1500m) and temperature (>40°C), supported by an 8-hour fuel tank and an IP21, H-insulation alternator with single bearing design. The MLC125 Diesel Generator Set (88kW, 60Hz, 240V) runs on the Cummins 6BT5.9-G2 engine, a 5.9L six-cylinder unit delivering robust torque and load carrying, enclosed in a silent enclosure rated at 78db @ 7m for compliance with urban noise regulations.
Platform Compatibility and Service Assurance
Across the lineup, dual-voltage compatibility (such as 230/400V, 110/220V, and 277/480V) and compatibility with third-party ATS and parallel systems extend the practical deployment options for these generator sets. Delivery formats include Silent Type (Enclosed), Open Type (Common base), Trailer Type (Mobile), and Vehicle Mounted configurations, along with private deployment and customized enclosure options.
Warranty coverage is tiered by model: MLC110, MLC115, and MLC125 carry a standard 12 months or 1000 hours warranty, while premium models including MLC30, MLC65, and MLC90 carry an extended 18 months or 1500 hours warranty. After-sales support includes engine parts catalogs, operation manuals, and factory test reports, reinforcing the transparency theme that begins with the visualized operating data on the controller displays.
Industry Reach
Minlong Power's generator sets serve manufacturing, telecommunications, construction, marine applications (via optional cooling systems), and emergency services, reaching customer types such as industrial facilities, commercial buildings, remote job sites, and vehicle-based power generation units. This breadth reflects a product matrix engineered around Cummins engine reliability, visualized controller data, and configuration flexibility suited to varied operating conditions.
