How to Choose a Prime Power Generator
Dingbo supply professional and honest service.
Heavy-duty applications require heavy-duty power. And, unfortunately, some of the most demanding industrial jobs are isolated from a central electrical grid.
In other instances, the task at hand is so critical that there isn't room for any utility power outages, like a hospital or cold-storage facility.
If you manage such an industrial or critical facility, then you need a constant source of electrical power that only a continous power generator can provide.
Continuous power generators, also known as prime power generators, serve as the primary source of electrical power for a given application and typically have an output ranging between 25 kilowatts and 1 Megawatt. They can run continuously (24/7) at variable and maximum loads to completely replace the utility provider, if necessary.
Prime-rated generators are not to be confused with emergency standby generators, which are meant for emergency power only. Typically, standby generators shouldn't be run for more than 200 hours per year and cannot permanently replace the utility provider. Continuous power generators, on the other hand, can run for an unlimited number of hours when properly maintained.
Prime power diesel and natural gas generators are available. We will discuss the pros and cons of each fuel type in more detail below.
Prime power generators are used as the main power source in a variety of industrial, medical, and heavy commercial applications.
Primary generator uses and applications go beyond the short list above. Any remote or off-grid need is a possibility.
Before making any continuous power generator purchase, you need to determine whether your application falls under the Environmental Protection Agency's (EPA's) Tier 4 regulations.
Tier 4 is designed to reduce emissions, such as nitrogen oxides and particulate matter, from diesel engines. If your application intends to use a diesel generator as its primary power source, then you need a unit that meets Tier 4 requirements.
However, using a natural gas prime power generator is environmentally cleaner and therefore does not fall under Tier 4. But, natural gas generators are
still
subject to their own special EPA compliance guidelines.
It's important to familiarize yourself with the full extent of Tier 4 regulations (diesel) and EPA guidelines (natural gas). Find more information in the EPA's Regulations for Emissions from Heavy Equipment with Diesel Engines.
Installing a prime power generator is an involved process that should be handled by a certified installer that specializes in prime power or industrial applications.
One of the most important aspects of the installation process is being aware of local codes and standards, especially air quality compliance boards. These typically supersede EPA requirements and can be more exacting.
The
South Coast Air Quality Management District
(SCAQMD) in southern California is a good example of a local/regional compliance board that has mandatory requirements governing engine emissions, such as those coming from prime power generators. Anyone installing prime power in that region, or regions with similar regulations, will need to familiarize themselves with those codes.
Because applications are so varied, in most cases your generator will need to be customized and built-to-order. Expect to undertake a thorough sizing and planning process with your manufacturer before anything gets installed.
In some instances, continuous power generators can be used alongside utility power to benefit everyone involved.
For example, the utility provider will supply a user with power up to a certain threshold. Once that threshold is reached (usually during peak usage), the user's generator will provide any supplemental power to make up the difference.
The utility will often pay the user for providing the additional power. It can also work in reverse with the generator running at a fixed output. If demand peaks, the utility provider makes up the power difference.
These load management deals allow the utility to more effectively predict and manage the amount of power supplied across the entire grid. They also minimize the electrical burden on both the utility and end-user while allowing both to meet their power goals.
As mentioned above, there are pros and cons to both diesel and natural gas prime-rated generators. The table below compares the two types.
Diesel Prime Power
Gas Prime Power
Less maintenance/downtime More maintenance/downtime Smaller in size Larger in size Louder Quieter Can be more expensive due to Tier 4 requirements Less expensive; no Tier 4 requirements Diesel must be acquired and stored; not as readily available A gas line provides consistent fuel; can be interrupted in disastersUltimately, your continuous power generator fuel choice should reflect the needs of your application. For example, someone in the fracking business will have access to cheap natural gas. On the other hand, a military base far away from a gas line will obviously need to choose diesel.
Considering the application, along with the equipment/maintenance costs and current fuel prices, will help you make the right choice.
In order to operate continuously at peak performance, prime-rated generators should be on a regular maintenance schedule. You should base this schedule on NFPA 110 standards, manufacturer recommendations, and environmental conditions such as altitude and humidity.
Large companies might have an in-house engineer who can handle maintenance, while smaller ones can hire a local generator contractor. Some manufacturers also offer maintenance services themselves.
Typical maintenance includes:
The most important aspect of maintenance is to have a trained and certified professional doing it consistently. Never skimp on maintenance; otherwise, problems may creep up when you can least afford them.
Ultimately, installing a prime power generator isn't about choice; it's about necessity. If you need continuous, reliable power and don't plan on using the utility, then you need prime power.
Once you recognize this need, you should familiarize yourself with EPA regulations depending on which fuel choice is best for your particular application. Finally, ensure that a licensed professional installs and maintains the generator throughout its life.

A generator is vital for power provision when there are emergencies or to sustain your operations smoothly. It is important to know about the different types of generator options for power needs, budgets, and aspects to consider while purchasing a used generator.
Let&#;s take a look at the many advantages of purchasing a second-hand generator and give you some tips for increasing its efficiency and essential characteristics.
The generator type selection is very important to make it fit your specific needs. There are four main types of generators to choose from:
Portable generators are widely applicable and also have a wide range of applications. They are widely used in mobile workshops. This makes them great choices of portable power for those who need it on the go.
The standby generator is a backup power source for commercial or industrial premises. These generators automatically start when there is a power cut, making for a smooth transition and continuous electricity supply. They form an integral part of the business and also institutional emergency preparedness.
Another important decision that has to be made when choosing a generator is the choice of fuel for it. Different generators operate on different fuel types, each with benefits and concerns. The common fuel options for generators include:
Diesel generators are very reliable and also economical power systems. They are long-lasting and preferred for industrial use. Lower fuel consumption and longer life than other fuels also characterize the characteristics of generators.
Natural gas generators are widely used in standby and continuous power modes. They are directly tied into a natural gas pipe supply that guarantees an uninterrupted fuel source. If operated for a long duration, these generators require very low maintenance.
One of the key steps in selecting an appropriate generator is calculating your power needs. The wattage required for running the essential machines during power outages is defined by the number of devices you want to link to this generator. Here's a step-by-step guide to calculating your power requirements:
List all the industrial machines and devices you deem important during blackouts. This may include lighting, machinery, heating or cooling systems, communication devices, medical equipment, and more.
Get the wattage ratings of every machine on your given list. This data is usually included on the nameplate or user manual. If the wattage is not given, you can search on different websites or ask for help from a supplier.
Total the amount of wattage needed to run all necessary machines to determine the total power needed. This will allow you to determine the minimum wattage that your generator should be capable of generating.
Some machines with electric motors usually need much power during startup. When choosing a generator, consider the starting surge to ensure it meets the initial power demand.
Wait for any future power requirements that you might need to add in the coming time. If you want to increase the electrical load, it is recommended that a generator with enough capacity for both the current and also future needs be selected.
The process of purchasing the generator includes budgeting. Although generators can be purchased at different prices, you must balance cost and quality to get a reliable power solution. Here are some factors to consider when working out your budget:
There is the purchase cost for the generator, including any associated accessories or installation costs. Some other generators and fuel types may have very different initial costs.
Include the operating costs over time, such as fuel usage and repairs. Although some fuels are more cost-effective, the long-term equipment ownership costs should also be considered.
The long-term value of the generator looks good. Look into various facets like fuel efficiency, dependability, and the make of the generators that are reputed to be durable.
The total cost of ownership is calculated by considering the initial and recurring costs. This method ensures that the chosen generator corresponds with your budget while offering huge value overall.
Although purchasing a pre-owned generator can be cheaper, numerous essential factors must be considered to get the value for your money. Here are the key aspects to keep in mind when purchasing a used generator:
The age and the total number of running hours indicate it is in good condition overall. A generator could be as old as several years, but with relatively low total running hours, it might still meet the requirements. However, a younger generator with plenty of hours to run could have undergone severe wear and tear.
Ask about the past repairs and the regular servicing of this particular generator. In contrast, a generator that has been properly maintained and inspected regularly will likely be in very good working condition. On the contrary, a generator plagued with frequent repairs or poor maintenance should be alerted.
A load bank test is a very important element in determining the performance of a used generator under the operating conditions. The test mimics the real working conditions, enabling an evaluation of the generator performance and rated charge. An honest dealer should not hesitate to undertake a load bank test to prove their generator's functionality and capability.
Conduct a complete visual assessment of the generator to ensure no wear and tear, damage, or corrosion. Inspect the external parts, including the engine, alternator, and control panel. A generator in good condition should have minimal physical wear and no visible damage.
Check the generator's wiring and also welds for great quality. Loose or kinked wiring can cause electrical problems, and compromised welds may affect the integrity of the generator's frame. Therefore, the overall integrity of these elements must be ensured to guarantee a safe and reliable generator operation.
Operate the generator and hook up a device or load to make sure it does its job well. The first-person experience of this operational test is vital to determine whether the generator works as it should and if there are any irregularities in the output power or uncommon noises for a normal operation.
Select a reliable supplier known to provide high-quality used generators. Collect the information on consumer opinions, reviews, testimonials, and the supplier's reputation within an industry. A reliable dealer will have better and more accurate information on the history and condition of a generator.
Knowing the previous uses of the generator may give some very valuable information on its wear and tear. However, generators for standby purposes may have endured fewer running hours or much less stress than those used as the primary power sources. Inquire about the generator's past uses to determine whether it is appropriate for your special case.
Although a degree of risk is associated with purchasing a used generator, obtaining a guarantee from the vendor can give you more confidence in your acquisition. Ask about any available warranties or guarantees and ensure you fully understand the terms of use. An established distributor should be willing to guarantee their product's quality and provide insurance that the generator will function properly.
There are several advantages to investing in a used generator, which make it a very attractive option for diverse applications. Here are the key benefits of buying a used generator:
Cost-effectiveness is one of the major benefits associated with buying a second-hand generator. The used generators are much less expensive than the new ones, so companies and individuals on a very tight budget can buy a reliable power source. However, this can be critical to those with limited means or budget restrictions.
Buying a used generator typically entails less delivery time than ordering a new one. Manufacturing and delivery time for the new generators may result in delays in getting a reliable power source. On the other hand, previously used generators are very easily accessible, enabling faster acquisition and implementation. This shortened lead time is critical for emergency cases where a quick power solution must be addressed.
Buying a second-hand generator does not require much paperwork compared to procuring a new one. Some new generator purchases require a lot of paperwork, such as warranties, certifications, and compliance documents. Instead, the paperwork for used generators is usually much less cumbersome, thus facilitating the purchase. This may be very beneficial to the companies and also individuals who want a smooth and easy transaction.
The used generators are kept in good condition and can deliver high reliability and efficiency. Most generators go out of use or are sold after they have been used for their original purpose, and with proper maintenance, they will continuously deliver reliable energy. Picking a previously owned generator with documented regular maintenance and an extensive assessment
There is a certain customization and flexibility in the used generators that are not easy to find with new ones. Since the used generator market is diverse, you can choose a unit that fits your power needs perfectly. This versatility enables you to select a generator with the right capacity, options, and specifications for your particular circumstances. Whether it is a standby generator for an individual business operation or the portable variety needed for your outdoor activity, customers interested in second-hand generators have plenty of options.
To maximize the purchase of a generator for sale and ensure its proper functioning, it is very important that one focuses on regular maintenance while observing the best practices. Here are key tips to enhance the lifespan and efficiency of your used generator:
Even an old generator does well with the proper servicing. First, establish a good maintenance plan and then stick to it religiously. Routine servicing is identifying if the fluid levels are proper, doing electrical components of visual inspection, and ensuring the lubrication. Routine maintenance also prevents possible problems and prolongs the generator's life.
The two essential parts that make the work of a generator smooth are its bearings and bushings. With age, such components become worn out, leading to efficiency loss and breakdowns. It should regularly monitor and replace the bearings and bushings as frequently required to ensure their perfect performance.
The correct fluid levels are very necessary for a functioning generator. Check and regulate the oil, coolant, and fuel levels regularly. Ensure these fluids are at their recommended levels and replaced as required. Lack of fluids can cause the heat
Inspect and replace parts periodically. Bearings and bushings are essential to a generator to ensure the device's proper functioning. Maintaining the following elements in good shape ensures they function well for a long time.
When choosing a generator, look at the other features that improve accessibility, safety, and portability.
Generators can produce the toxic gas carbon monoxide (CO). The automatic CO shutoff feature guarantees a generator's immediate turn-off when high CO concentrations are detected, increasing safety.
A feature of the electric start makes starting a generator easier. This is particularly useful in emergencies; it saves individuals from manually pulling a recoil starter.
The low-oil shutoff feature safeguards the generator's engine, which automatically shuts off if there is too much oil. This prevents the wear and tear of the generator system.
The fuel gauge presents a very efficient method to keep track of the generator's gas level. This function enables you to refuel in advance and avoid unexpected stops.
Look at the noise level of your generator, especially when you intend to use it in near residential environments. Lower decibel-rated generators are quieter and also more appropriate for places where noise is an issue.
Selecting an old generator requires considering several factors, such as the kind of generator with a necessary fuel options ratio and money constraints.
