Basic Safety Tips For Used Industrial Generators

By | Backup power, Critical Power Products & Services, Generators

Used industrial generators often find new life as standby generators. This is no surprise since diesel generators are some of the longest-lasting engines on the market. But just because they’ve lasted this long doesn’t mean they are automatically safe. There are several safety precautions you’ll need to take to keep your generator operating properly for years to come.

5 Basic Safety Tips For Used Industrial Generators

Safety measures involve installation, operation, and maintenance. The 5 tips below hit on each of these three aspects of generator safety.

  1. Start with an electrician. Before you even buy a used industrial generator, you should have an electrician determine your power needs to make sure you’re getting the right-sized generator.


  1. Don’t forget the basics. Just because this is a big piece of machinery doesn’t mean it requires complex safety practices. Avoid loose clothing and jewelry. Make sure everything is turned off before you start working on it. No smoking around the generator. Tie long hair back or wear a cap. Wear gloves and safety goggles. Keep a first aid kit handy and always work with a partner.


  1. Make time for inspections. You inspected the generator before you bought it, now keep it up. Inspect it again before it is installed and then set a regular inspection schedule to check for loose and missing parts, dents, dings, and other damage and to check fluids and change filters.


  1. Site it properly. Used industrial generators should to be placed outdoors. Ideally, they will be set inside a protective enclosure and on a concrete pad. Outside placement eliminates the risk of dangerous fumes being inhaled while the enclosure and pads help reduce the effects generator noise can have on our hearing. 


  1. Follow the manual. Used industrial generators should come with a manufacturers manual. Use this manual to determine the recommended maintenance, repair, and installation requirements. Not only will this keep the generator in peak operating condition, it will help protect you with warranty (if applicable) and insurance protection if something goes wrong.

How To Buy The Right Used Industrial Generator

By | Generators

Buying a used industrial generator isn’t just about specs and models.

There are a lot of other factors involved in choosing the generators that are right for your company. Here are some ways to avoid any issues during the buying process:

Is Your Retailer And Installer Reputable?

Choosing a vetted, reputable used industrial generator retailer and installer is possibly the most important decision you’ll250 kW Cummins Diesel Generator 3 make in this process. If you can’t trust your retailer, you may end up with the wrong used industrial generator, or you may get stuck with a generator that doesn’t perform the way you need it to.

What Are Your Power Needs?

How much power will you need and what will you be powering? Does your business need or want to power emergency equipment only? Does your business need full power or close to full power to function? Answering these questions will help you to determine how much power you’ll need.

Which Fuels Are Available To You?

Most people don’t think of this, but fuel availability is essential. We’re not just talking about what’s close by, but also what is the most cost effective and stable fuel in the area. Most generators run on either diesel, propane, or natural gas. Depending on where your data center is located will determine what’s most available.

Expert Tip: Just because a type of fuel is close by, doesn’t mean it’s the best to buy. Stability is a huge factor in fueling a generator. Make sure you choose a generator that runs on the most stable fuel available.

A Guide To Maintaining Your Used Industrial Generator

By | Generators

Like any other machine, you can get a lot of use out of your used industrial generator by performing regular maintenance. Now, some maintenance has to be done by professional technicians, but there are some things you can do on your own. Here’s a guide to what you can do and what you should leave to your technician.

Inspect Your Used Industrial Generator

Inspecting your generator and the areas surrounding your generator can avert many preventable problems.

What You Should Do: Visually inspect your used industrial generator.  Look for signs of wear and tear and note them for your service technician. Make sure you keep your generator, the area surrounding your generator, and the protective housing clean and clear of branches and debris. Make sure the vents are clear of debris and dirt.

What Your Technician Should Do: Your technician will also visually inspect your generator, as well as clean any debris you missed. They’ll inspect the muffler, manifold, exhaust pipe along with the entire exhaust system. They should check joints, welds, and connecting gaskets for leaks. If they find any leaks, a technician should be able to tighten gaskets and repair most joints and welds.

Test And Inspect Your Battery

Undercharged or weak starting batteries are the one of the most common reasons for generator failure, so, maintaining your battery is a must.

What You Should Do: It goes without saying that your battery needs to be charged regularly. But, even if a battery is well maintained and charged, lead-acid batteries can deteriorate over time, so they must be changed, so you should check your battery for outward signs of wear. Remember, checking the voltage is not an efficient way to test wear and battery power.

What Your Technician Should Do: Your technician should test your generator under load, which can prevent starting problems. If you see outward signs of deterioration, your technician can investigate and confirm your findings. They can also change your battery if it’s deteriorating or not holding a charge.

Check Your Cooling System

Your cooling system is essential because it keeps the machinery cool enough to operate. Keeping it in good working order can prevent costly wear and damage to your generator’s motor.

What You Should Do: Make sure you have enough coolant and make sure you have the recommended coolant to fluid ratio. Make sure you’re using the soliton that’s recommended by the manufacturer or your technician.

What Your Technician Should Do: Your technician will also check your coolant levels. They’ll be equipped to flush coolant, if they notice any contaminants. As we mentioned earlier, they can also determine if there are any dangerous leaks.

Check Your Fuel

Fuel maintenance is crucial because fuel can be contaminated and degrade over time, especially diesel and gasoline. This can contribute to generator failure and can be quite dangerous.

What You Should Do: Your fuel tank should be equipped with a valve, which allows you to drain any water that’s accumulated. You should also keep the fuel tank full of fresh fuel.

What Your Technician Should Do: Your technician should take a fuel sample from the supply line and from the bottom of the tank. They should extract and visibly inspect samples monthly, especially if your area is prone to blackouts and power outages.

By | Generators

Used industrial generators can save lives and businesses. They can withstand extreme use and extreme weather. However, there are many myths and misconceptions about the care, use and maintenance of used industrial generators. Below we’ve added some much-needed clarification about used industrial generators and debunked some of the major myths.

Debunking The Most Prominent Myths About Used Industrial Generators

125 kW Cummins Natural Gas Generator 4

Generators DO Need Regular Maintenance

Every machine known to man needs some kind of regular maintenance, including used industrial generators. A good game plan is a mix of scheduled maintenance and preventative measures, like battery testing, to keep your used industrial generator in tip-top shape.

Expert Tip: You should run your emergency power system regularly to so you know how well it’s functioning at all times.

Size DOES Matter

You can’t just buy any used generator and call it a day; different sized generators work best for different jobs and circumstances. How many kilowatts is a major factor in determining the right size generator for your needs. Also, motors with compressors use more power than motors without, so factor that into your criteria as well.

You DO Need An Automatic Transfer Switch

Most used industrial generators already come coupled with automatic transfer switches, or ATSs. But, if yours doesn’t have one, it’s a good idea to get one. ATSs will automatically start your generator during an incident or power outage, which could literally save your business.

All Fuel Types Are NOT Created Equal

Fuel type is important to consider when you buy a used industrial generator. Remember that each fuel works differently and they’re availability is different in every area. Also, consider how well an individual fuel works in your climate.

You CANNOT Install A Generator Just Anywhere

The place you choose to install your used industrial generator should be easily accessible. The location should also be high enough to protect against water damage. If you’re installing indoors, you must follow safety precautions. Always make sure you’re in compliance with federal and state safety and installation guidelines.

Prepare For Cold Weather Outages With An Industrial Diesel Generator

By | Emergency Preparedness, Generators

Winter is indeed coming and that can mean cold weather power outages. Unfortunately, whether it’s tree limbs on power lines, a car skidding into a utility pole or ice affecting the connectivity of your infrastructure, you can always expect power outages during snowy, icy weather. Lucky for us, there is a solution. You just need to buy, service and maintain your industrial diesel generator.

A Generator Is A Powerful Tool

A generator is a powerful tool in the fight against power outages. But, an industrial diesel generator isn’t the only weapon you’ll need. Here are some other ways you can combat power outages and triumph over the cold weather outages.

Come Up With A Plan

Regardless of whether they’re caused by human error or weather alone, you know that cold weather outages will happen. Come up with a comprehensive plan to keep your business afloat during an outage. Be as detailed as possible and factor in any scenario you can think of.

Make Sure You Have The Right Tools For The Job

Determine how much power you want your generator to cover, whether you just need emergency power, or your business needs full power. Calculate how much power you need and make sure your generator can handle about 10-20 percent more than that, in case of a dire emergency. A trusted generator retailer can help you to find a generator that fits your business’ needs.

Maintenance And Fuel

You should always have enough fuel to power your business through the worst storm. Ask your county for data on the length of storms and how often they cause outages. Also look for data on how often outages are caused by winter accidents. Estimate how often and how long the outages are, then buy enough fuel to sustain you through that time. Approximate fuel consumption charts can help you to make those calculations. Be aware of laws regulating which ways and how much fuel you can store.Winter Storm

Don’t Suffer Through Another Power Outage Without A Backup Diesel Generator

By | Emergency Preparedness, Generators

You don’t have to be the victim of the next inevitable power outage. Preparing yourself with a backup generator can mean the difference between business as usual for your company or lost revenue.

The next step is finding the right generator for the job. Here are some reasons why a backup diesel generator may be the right generator for you and your business.HiPower on trailer


Most generators run on gasoline, propane, natural gas or diesel. Although any type of emergency generator will offer your home or business temporary power during outages, diesel is a more cost-effective fuel. It offers more power per ounce of fuel than propane, natural gas or gasoline. Diesel is not expensive or difficult to get, either.


Though diesel is flammable, it is less volatile and flammable than other fuels. This may seem insignificant, but most power outages are caused by hurricanes, tropical storms and other damaging weather, which in turn can cause dangerous conditions. Using a highly volatile fuel compounds an already dangerous situation.

Easy To Use:

Its true, backup diesel generators can be a little intimidating for first time buyers. Most backup diesel generators have easy and straightforward maintenance and operation, especially if your generator is professionally installed. You should always follow safety procedures and read all of the literature about your generator.

Reduce Storm Stress! Rent A Standby Generator This Winter

By | Backup power, Emergency Preparedness, Generators

Winter is on its way! And we may all be looking forward to the New Year or the holidays, but businesses have an added stress during this time of year that’s enough to dampen any holiday spirit. Winter brings cheer, but it also brings stressful, damaging winter storm power outages. Storm stress is real and if your business is unprepared for the winter, it just compounds that stress. You can help to eliminate storm stress by preparing for winter storms in the fall, before a disaster happens. One of the best ways to prepare is to have a standby generator on hand. Depending on your need and the size of your business, a long-term rental agreement may be the best option.

Why Rent A Generator Long-Term?

A long-term standby generator rental can help your business reduce downtime. A generator that is in standby mode can deliver power to your business when power infrastructure is down due to winter storms. Depending on the severity of the storm, emergency crews might not even be able to reach your business, let alone help repair and restore power. A standby generator offers emergency power that will keep your business afloat and connected to your cloud or data center. This way, you lose little or no time while your community thaws out and repair crews are sent in.

Calculating Your Storm Window And Gaging Your Fuel Use

Determine your community’s “storm window” by averaging the number of winter storms in the last 3 years and averaging how spread out they are throughout the winter months. Ask your standby generator retailer how much fuel your generator will need for a day, week, or month. Depending on your storm window, keep a supply of fuel to last you through your estimated period, plus at least two extra weeks. This will help you to gage how much fuel you’ll need, and it will give you a buffer if repair crews take longer to repair power lines and other infrastructures.

Critical Power Offers Standby Diesel Generators And Something Even More Important

Critical Power Products and Services offers standby diesel generators and something even more important, peace of mind. Contact us to find out how we can help your business reduce stress and keep the power on this winter.

The Importance Of Generator Enclosures And Other Necessities This Winter

By | Backup power, Generators

Your generator is designed to take care of you during winter storm outages, but you need to do your part to take care of it, too. Generator enclosures literally provide shelter from the storm, and enclosures cut down on the overall wear and tear of your generator. Other necessities, like cooling towers and chillers, can help keep your generator working smoothly all winter long.

What Your Generator Needs To Run Smoothly This Winter:


This isn’t a must-have, but with all of the ice and snow, your generator may seem noisier. A soundproof generator enclosure can help to eliminate some of the noise associated with generators.

Cooling Towers And Chillers

I know what you’re thinking, isn’t it cool and chilly enough in the winter? Actually, we want to keep a generator cool, but we don’t want it to freeze. Chillers and cooling towers are actually warmer than the temperature outside, so they keep generators cool, but not frozen.


Your enclosure may include louvers, dampers or shutters. They offer ambient airflow through the generator engine’s radiator. This helps to naturally eliminate overheating or overcooling.

Louvers can be activated by the generator’s thermostat or coolant levels. Like the classic louver design, they are designed to let air in, but keep snow out.

Snow Hoods

Snow hoods are features on generator enclosures that help to prevent snow from accumulating near the generator itself. Some manufacturers offer snow hood kits, but some come as part of an enclosure package. If you purchase a kit, you may have to relocate the generator’s exhaust, so it’s better to purchase a generator enclosure that includes a snow hood.

Other Precautions To Take50 kW Blue Star Diesel Generator

You may want to consider other precautions when preparing your generator for winter weather. You may want to consider winter fuel additives, to keep your fuel flowing freely. You should also make sure your generator was serviced before the winter begins.

Generator Enclosures Don’t Just Shield Your Generators

Your generator is the one tool that can keep your business afloat this winter. So, by shielding your generator, you’re also shielding your business. Critical Power Products and Services can help find the right generator enclosure and accessories for your area and needs.

Industrial Diesel Generators: Know Your 3R’s When Prepping For Tornado Season

By | Emergency Preparedness, Generators

Thankfully, tornado season is behind us for another year. However, the best time to prepare for tornado season is right after tornado season. States that are in “Tornado Alley” should begin making preparations immediately after the threat of tornado season is over. Checking and servicing your industrial diesel generator and other emergency equipment is a must. 1250 kW Cummins QSX45 Diesel Generators over all

There are three things that need to be done immediately after tornado season is over: Rebuild, review, replenish. We like to call them “The 3 R’s.”

Prepare For Tornados With The 3 R’s


If the foundation for any of your buildings or equipment is damaged, you need to rebuild them to be structurally sound again. If that’s not possible, you may need a new location. This also includes any housing around your industrial diesel generator or any other data equipment housing. If your buildings or equipment have superficial damage, like missing shingles or seals, you need to repair them.


Everything that was not damaged needs to be checked to ensure it’s still in working order. This is especially important even if you haven’t been hit. Simply because you’ll want to test to make sure your industrial diesel generator and other equipment works, especially if it’s been sitting for a while.


Now is a good time to replenish any supplies you lost or used, while tornado season is fresh in your mind. You may want to replenish generator fuel and other items that you need to survive or evacuate the next tornado.

Expert Tip: Use a fuel usage chart to help calculate how much fuel you might need during an outage.Cummins Diesel Generator

Things To Keep In Mind For The Next Tornado Season

Even Small Tornados Can Be Dangerous. Just because they can’t take down a building, they can take down electrical lines, which can cause fires and other types of damage.

Tornados Come In Clusters. It’s true, there are rarely singular tornados. Count on at least two to four touching down at a stretch. Make sure to evacuate, if necessary, before the first tornado hits.

Don’t Forget The Aftermath. Unless you’ve been severely hit, the worst part of the tornado is the aftermath. This is why it’s crucial to have enough fuel and a tested industrial diesel generator because you don’t know how long you’ll be without power.

Critical Power Can Help Your Business Get Ready For Tornado Season
