1. Safely Storing Fuel For Generators

    February 26, 2015 by admin
    Safely Storing Fuel For Generators

    Generators provide power when it is not available from the electrical grid. That means you’ll need an external fuel source stored nearby so you can power up the generator when necessary. Since generator fuel is flammable and can contaminate soil and water there are certain safety concerns surrounding fuel tanks.

    Types Of Fuel Tanks

    Fuel must be stored in specially designed tanks to prevent leakage, spills, and fires. There are three primary types of fuel tanks used with generators:

    •    Sub Base Tanks fit above the ground but below the base of the generator set. They are a good option if you are storing less than 1,000 gallons of fuel on-site.
    •    Underground Storage Tanks are used if more than 1,000 gallons must be stored. These tanks are the most expensive to install and repair, but they also last the longest. The tanks are surrounded by concrete to protect the surrounding area from leaks and spills.
    •    Above Ground Storage Tanks are also used to store more than 1,000 gallons. The biggest concern with above ground tanks is flammability. These tanks must be installed at a minimum distance from facilities to prevent the spread of fire if it breaks out.

    Safety Features

    Several safety features are built into tanks or must be added when the tanks are installed in order to minimize hazards like fire or contamination from spills and leaks. Features include:

    • Double-wall construction.
    • Heavy-gauge, corrosion-protected steel or fiberglass reinforced tanks.
    • Piping and fitting attachments to control fuel supply and return, ventilation, pressure and fuel alarms.
    • Installation at minimum distances from other structures.
    • Dikes built around the tanks to help contain spills and leaks.
    • Protection from the elements for sub-base and aboveground tanks.
    • Protection against ground and water contamination is needed for underground tanks.
    • Approval for installation must be obtained from the State Fire Marshall. This applies to large commercial or industrial generators as well as domestic generators and small business generators.
    • Safety and Fire Codes must be followed during manufacturing and installation of generator fuel tanks.

  2. Portable Vs. Stationary Generators – Which One Do You Need?

    February 23, 2015 by admin
    Portable Vs. Stationary Generators – Which One Do You Need?

    Both portable and stationary generators both provide electrical power to homes and businesses, which keeps things up and running when other power sources are unavailable. But they are two different machines, intended for use in different situations. If you’re in the market for a new or used generator, use this quick reference guide to determine which type of generator will best meet your needs.

    Portable Generators

    While the name implies that these generators can be moved and relocated as need dictates, they are not intended for permanent installation or long-term use, but rather as a standby-by or back-up power source. Portable generators are best used for:

    • Temporary, stand-alone applications.
    • Run times of less than 12 hours.
    • Power requirements of between 500w and 17.5kW.
    • Powering critical appliances in residential situations.
    • Providing power for small applications where there is no access to a local power grid such as construction sites, campgrounds, and farms.

    Portable units are small enough to house in a camper, trailer, or garage when not in use. They provide power via extension cords and should be moved outside before being turned on so that there is plenty of air to cool the engine and keep it well ventilated. They run on many different types of fuels. Depending on the model, they can run on diesel, biodiesel, gasoline, propane, or natural gas.

    Stationary Generators

    Stationary generators are more rugged, durable, and long-lasting than portable generators and provide higher power outputs. Stationary generators are best used:

    • With very high power requirements.
    • When power is needed for more than 12 hours at a time.
    • To maintain critical business or operational systems.
    • To provide site-wide power for businesses, hospitals, factories, and other large-scale commercial operations.

    Unlike portable generators, stationary generators are hard-wired into the main power panel. There is no need for extension cords to get power to critical systems because the generator feeds power directly into the main electrical system. These generators may be started up manually or automatically via an automatic transfer switch (ATS). The ATS signals the generator to start or stop operation, depending on the input received from the power grid/power lines. They run on the same fuel types as portable generators, but require a permanent connection to an on-site fuel tank.

    Choosing A Generator

    You’ll need to examine your power needs to determine whether you should buy a portable or stationary generator. Do not be swayed by price alone. Portable units are less expensive than stationary units, but they also aren’t as powerful or long-running. On the flip side, stationary units can be out of the price range of many smaller businesses.

  3. Biodiesel Fuel and Generators

    February 19, 2015 by admin
    Biodiesel Fuel and Generators

    As the search continues to find alternatives to traditional fossil fuels, biodiesel fuel is garnering attention as a viable option. While this renewable energy source may not be quite ready for widespread commercial use, it has proven to be remarkably effective in certain applications involving diesel generators.

    All About Biodiesel

    Biodiesel fuels are made from various types of vegetable oils. Interestingly, biodiesel fuel was first developed by Rudolf Diesel, the inventor of the diesel engine. Way back in 1895, Diesel saw a need for alternatives to fossil fuels and found a way to use readily available agricultural crops to create fuel.

    There are two ways vegetable oil can be used as fuel:

       Straight vegetable oils can be used if the engines can handle the higher viscosity. Vegetable oil is thicker than conventional diesel so engines must be designed to handle that extra thickness if the oil is unprocessed.

       Oil that has been processed as biodiesel reduces viscosity, making it suitable for conventional diesel engines. Once processed, this fuel can be used as the engine’s primary fuel source.

    Pros And Cons Of Biodiesel

    As with any fuel source, there are pros and cons to using biodiesel.


    • Renewable energy source.
    • Can be made from waste/used vegetable oil.
    • Less polluting emissions than conventional fuels.
    • Better lubricating properties than conventional diesel reduces wear and tear on engines.


    • Low consumer demand means few options exist for using biodiesel.
    • Technical hurdles exist for using biodiesel extensively.
    • Lack of industry standards makes it hard to evaluate fuel performance and processing differences. 
    • Distribution limitations.

    Using Biodiesel Fuel In Generators

    One application where the advantages of using biodiesel fuel tend to outweigh the disadvantages is with diesel power generators. Diesel generators provide reliable off-grid power in areas where there is no power grid and sometimes no easy access to a fossil fuel source. These generators run day and night, putting a lot of strain on the engine. Biodiesel can be safely stored for use in these engines and the heavier viscosity of the fuel can help keep the engine lubricated, reducing maintenance and repair needs. Even generators that provide stand-by power are good candidates for biodiesel. Since standby generators are typically used in developed areas the fact that they are less polluting than traditional diesel generators is a huge benefit.

    Biodiesel fuel is making gains as a viable, sustainable source of fuel. Using the fuel in generators can be cost-effective, promote the biodiesel industry and technology, encourage investment in renewable sources of energy, provide reliable power without the pollution, and help meet the world’s ever-increasing energy demands.

  4. Used Generators are Perfect for Portable Power

    February 11, 2015 by admin
    Used Generators are Perfect for Portable Power

    Used generators are a great choice for dependable, portable power. Mobile generators go where you need them, when you need them. You can find models that run on diesel, propane, or natural gas, offering consumers plenty of options in portable power.

    Where to Use a Portable Generator

    The beauty of portable generators is that they can be used anywhere – at home, at work, at the cabin, or on the road. They are most commonly used for:

    • Backup power. Many businesses buy portable generators for backup or emergency power particularly if they don’t need to keep their entire operation up and running during a power outage. Portable generators are an excellent way to keep a few critical systems going, eliminating the need to buy a larger, more expensive solution.
    • Sites with no electricity. Portable generators are commonly used in field operations or at construction sites that don’t yet have electrical service hooked up. They are used to power lights, AC-powered power tools, heaters, and more.

    Advantages of Used Generators

    Portable used generators have several advantages over new generators, the biggest being cost-savings. Surplus or used generators will always cost less than new generators. They’ll also be readily available. With new generators, you may have to place an order and then wait for them to be built. Buying used avoids this problem.

    Don’t discount used generators simply because they bear the “used” label. Since portable power is often used as backup power, even decades old generators can run like new. Many used generators have very few hours on them, making them seem much newer than they actually are.

    Buy Used Generators At Critical Power Exchange

    At Critical Power Exchange we buy and sell surplus and used generators. After inspection, testing, and necessary repairs are made to the generators, we place them for sale. We have several used generators available right now. Visit our inventory page to find the right generator for your purposes or contact us for helping making a choice.

  5. Backing Up Your Business With Generators From Critical Power Exchange

    February 9, 2015 by admin
    Backing Up Your Business With Generators From Critical Power Exchange

    Business success is dependent on being able to actually do business. If you’re ever in a situation where there is a power failure and your business must be shut down, you are losing money for every minute you’re in the dark. But with a standby generator from Critical Power Exchange, that will never happen.

    How Backup Generators Work

    Backup generators are physically located outside of the business. They typically look just like an outdoor A/C unit and turn on automatically when there is a power failure. Commercial generators usually run on either diesel or natural gas and can be fully powering your business operations within seconds from the time the power fails.

    Backup generators constantly monitor incoming power. When that power dips or disappears entirely, an automatic transfer switch activates the generator. This is important because it means that the generators work during total power failures as well as during temporary power dips, like brownouts. So even if the rest of the grid is suffering, you won’t be.

    What can be Backed Up with a Generator?

    Anything that runs on electricity can be backed up with generators. Commercial units are designed to seamlessly kick-in and support all aspects of the business that rely on power such as lighting, appliances, security systems, HVAC systems, computers and network systems, even gas pumps. This continuity of power is necessary for businesses that have perishables that must be refrigerated but it can be a literal lifesaver for hospitals and medical facilities that must have 100% reliable power no matter what, and most especially in times of distress.

    Find Surplus and Used Generators at Critical Power Exchange

    Even though a back up generator will likely pay for itself the first time you have to use it, the initial purchase price can lead to sticker shock. Used or surplus generators from Critical Power Exchange are a great way to obtain high quality and reliable generators to support your business.

    6 Tips to Use When Researching Used Generators for Sale

    Buying a used generator is a great way to save money and still get a high-quality product with the capacity to handle your power demands. Even so, it’s smart to take the time to do a little research before committing to a purchase. The extra work will more than pay off when you find great used generators for sale at can’t be beat prices.

    Diesel Generators

    6 Tips for Choosing Among Used Generators for Sale

    Check these six things before committing to buy a used generator. This checklist will ensure you’re getting a quality product that is worth the price you’re paying for it.

    • Type of Generator. There are many different kinds of used generators: diesel, propane and natural gas for example. Make sure you’re looking at the type of generator you need (or want). A great deal won’t mean much if you end up buying the wrong type of generator.
    • Age and Usage. Check the hour meter to find out how much runtime the generator has accrued. Ask about its age and history – how and where it was used and what type of maintenance it has had, was it used continuously or was it strictly stand-by? A standby rated generator often has fewer hours on it and has had better maintenance than a continuously run Prime rated generator, however Prime rated generators are built much stronger and have a higher initial cost.
    • Manufacturer and Model Number. Who is the manufacturer? Knowing the name and model number lets you do some independent research into the company and the reliability of the specific model. Look for models that have a long history; they are likely high quality. Big name manufacturers include: Generac, Kohler, and Cummins.
    • Maintenance. More important than the age of used generators is their maintenance history. Ask to see maintenance records to see what type of maintenance it has had, how frequently, and if certified technicians performed the maintenance or not.
    • Consider the Seller. In almost every situation it is best to buy used generators from a respected reseller or dealer than a private seller. Resellers and dealers will have inspected the unit before they purchased it and can tell you more about its history and maintenance.
    • Warranties/Guarantees. You can find used generators that come with warranties or guarantees, particularly if they have been remanufactured. In any case, ask about any warranties and guarantees that may be available.

  7. The Pros and Cons of Used Generators Vs. New

    December 18, 2014 by admin
    The Pros and Cons of Used Generators Vs. New

    If you’re in the market for a generator you’re probably wondering if it should be new or used. On the one hand used generators can save you a lot of money and time but new generators come full priced and lead time. If price and time are not a concern, you’ll need to base your decision on other factors.

    New GeneratorsBlue Star Generator


    •    Warranty. Standard manufacturer warranties range form 1-2 years and are included with every new generator.
    •    New components. Every piece is new. There hasn’t been a previous owner. This provides peace of mind to some buyers.


    •    Costly. You may pay as much as 50% more for new vs. used generators.
    •    Wait time. You may have to wait for the generator to be built, especially for larger models.

    Bottom line: New generators are a great choice for buyers who need or want a warranty, can wait for the generator to become available and can afford to pay full price.

    Used Generators


    •    Low Cost. Rebuilt, remanufactured, or even just really well-maintained used generators are extremely affordable when compared to the cost of buying a new generator.
    •    Available when you need it. Used generators are available when you need them. There’s no waiting for the piece to be built. CPE project managers work with the client to find the right generator for their project right away.


    •    No warranty. You won’t get a warranty with used generators, except in certain cases where the machine has been completely remanufactured.
    •    Previously used. This is the biggest disadvantage to buying used generators. You are taking a chance that the previous owner is being truthful about the generator’s usage and maintenance history.

    Bottom line: Used generators can be just as reliable as new generators without new product prices and without the wait time.

    Buying Used Generators

    If you want to buy used generators, it’s best to work with a reputable reseller or distributor. Companies like Critical Power Exchange use qualified technicians to test and repair used generators before they are made available for sale, that way you know you are getting a product that has been tested and is in good working order.
