The selection process begins by distinguishing between resistive, inductive, and mixed loads.
First, calculate the total rated power of all connected equipment, then convert this figure into kVA capacity based on a power factor of 0.8.
For primary power sources, a power reserve margin of 20% to 30% should be allocated; for backup power sources, a margin of 10% to 15% is recommended.
Furthermore, for impact loads—such as electric motors and compressors—the instantaneous starting power requirements must be specifically factored in and accommodated with additional capacity.
In harsh operating environments—characterized by high altitudes, high temperatures, or excessive dust—an additional 10% power reserve should be added.
Finally, verify the specific voltage specifications (single-phase or three-phase) and frequency requirements (50 Hz or 60 Hz) to prevent undersizing the unit, which could lead to overloading and a shortened service life.

Deutz air-cooled units do not require a radiator or antifreeze; they feature a simple structure, are maintenance-free regarding cooling systems, have a smaller footprint, and offer superior cold-start performance.
They are well-suited for small generator sets (under 150 kW), outdoor environments lacking a water source, and remote regions with low temperatures, offering cost-effective and hassle-free maintenance. Water-cooled models, conversely, boast higher heat dissipation efficiency, greater load stability, and lower noise levels.
They are ideal for medium-to-large generator sets (over 200 kW), industrial applications requiring continuous 24/7 operation, and environments characterized by high temperatures and heavy loads. For residential use, small construction sites, or communication base stations, air-cooled units are the preferred choice; for factories, data centers, and large-scale engineering projects, water-cooled models should be prioritized.

Deutz 60Hz models feature a rated power output that is 15% to 20% higher than their 50Hz counterparts.
Operating at higher rotational speeds, they deliver greater power and are compatible with 120V, 240V, and 480V voltages; these units are predominantly utilized in the North and South American markets, often serving as backup power sources.
Conversely, 50Hz models operate at lower rotational speeds, resulting in reduced engine wear and lower operating noise levels. They provide standard output voltages of 380V and 400V, making them well-suited for domestic markets—as well as Europe, the Middle East, and Africa—and are particularly ideal for long-term, continuous primary power supply applications.
Furthermore, these units support factory-configured dual-frequency switching capabilities to meet the diverse power requirements of multinational projects.

The selection standards for these two applications differ significantly; choosing the wrong configuration can drastically shorten the equipment’s service life.
When serving as a prime power source, the unit is required to operate continuously and uninterruptedly over long periods; therefore, it is recommended to keep the daily load between 70% and 80% and to maintain a power reserve of at least 25% to ensure consistent and stable output.
Conversely, when serving as a standby power source—which is only activated for short durations during power outages—the unit is capable of withstanding 100% full-load operation, and a power reserve of 15% is sufficient.
For standby units, it is recommended to run the generator under no-load conditions for 30 minutes each month and to adhere to a regular maintenance schedule; this prevents aging caused by prolonged inactivity and ensures that the unit is ready to start instantly in an emergency.

The entire range of Deutz generator sets supports automatic parallel operation functionality.
They can be paired with mainstream parallel controllers—such as those from Deep Sea, ComAp, or SmartGen—to enable synchronized grid connection, automatic load sharing, and alternating start-stop sequences across multiple units.
For optimal performance, it is highly recommended to parallel units of the same brand, series, and power output range; this ensures a high degree of compatibility within the control system, facilitates uniform load distribution, and minimizes the risk of circulating currents or overload faults.
Conversely, forcibly paralleling units from different brands or with significant power disparities is not recommended, as this is prone to triggering current imbalances and safety shutdown protections.
This capability makes Deutz generator sets ideally suited for providing clustered power supply solutions in large industrial parks, power stations, and data centers.

Deutz leads the industry in environmental adaptability; standard configurations allow for direct starting at -35°C, while the addition of a preheating device enables stable operation in extreme cold environments down to -45°C.
In high-altitude regions reaching 5,000 meters, thanks to an optimized air intake system, power derating is limited to just 9% for every 1,000-meter increase in elevation—a rate significantly lower than that of other imported brands.
For high-dust environments, the system can be upgraded with a multi-stage air filtration system to prevent clogging.
In high-humidity and salt-mist environments, the units feature anti-corrosion coatings and stainless steel fasteners, combined with an IP55-rated enclosure, ensuring long-term, stable operation in demanding conditions such as mines, deserts, polar regions, and humid coastal areas.

An open-frame Deutz generator set produces a noise level of approximately 80–85 dB at a distance of 7 meters.
With a standard silent enclosure, this can be reduced to 68–75 dB; a custom “super-silent” configuration can lower the level even further, down to 60–65 dB.
These levels fully meet the noise standards required for urban areas, hospitals, residential communities, and schools.
The generator set comes equipped with factory-installed vibration-damping structures, ensuring that its inherent vibration and noise control capabilities are superior to those of comparable models in its class.
We offer customization services for enclosed silent enclosures, generator room soundproofing and noise reduction, and exhaust system silencing modifications.
These solutions are custom-designed to comply with local environmental noise regulations without compromising the unit’s heat dissipation or power generation performance.

For a new unit, the initial maintenance service should be performed after the first 50 hours of operation; this involves replacing the engine oil and oil filter, as well as conducting a comprehensive inspection of the operating conditions.
Under standard operating conditions, the engine oil, oil filter, and diesel filter should be replaced every 300 hours or every 6 months. Every 1,000 hours, the air filter should be replaced, and the battery, fuel injection system, and drive belts should be inspected. Every 3,000 hours, the coolant should be replaced, and the turbocharger and valve clearances should be checked. Finally, every 10,000 hours, a major overhaul should be conducted to thoroughly inspect core components such as the cylinder liners, pistons, and crankshaft. Spare parts are globally interchangeable and easily procurable;
furthermore, the maintenance procedures are standardized, making routine upkeep simple and easy to perform.

Utilizing precision fuel injection technology from Germany, Deutz generator sets demonstrate exceptional fuel efficiency. Within their optimal load range of 70% to 80%, the specific fuel consumption rate is approximately 200–215 g/kWh. When operating at a low load of 50% or at full capacity (100%), fuel consumption rises to 220–235 g/kWh. Compared to domestic generator sets of equivalent power output, Deutz units offer 10% to 15% in fuel savings; furthermore, their long-term operational fuel costs are lower than those of certain other imported brands.
The units are compatible with both national-standard diesel and standard commercial diesel fuels—they are not particular about fuel quality—making them ideally suited for long-term deployment in construction sites, mining areas, and remote regions, thereby effectively reducing operational fuel costs.

Inspect the stainless steel manufacturer’s nameplate affixed to the unit’s body, as well as the engine’s unique serial number; these details can be cross-referenced against the official records within the Deutz verification system.
Verify that the engine block, turbocharger, and fuel injection pump all bear the authentic Deutz manufacturer’s markings, ensuring that no core components have been dismantled, modified, or replaced. Request the factory Certificate of Conformity, the comprehensive unit inspection report, CE certification, and the original manufacturer’s warranty documentation; the technical specifications of a genuine unit should align perfectly with those detailed in the official product manual.
