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.

As Renewables Flood the Grid, Opportunity Knocks For Building Management

As Renewables Flood the Grid, Opportunity Knocks For Building Management

When we talk about adding renewable energy to the U.S. power supply, there is often a lot of talk about getting that power from the supply source (the solar farm or wind turbines, etc.) to the local power grid. There is less talk of what happens once that power hits the grid and how buildings may be able to adapt to the influx of power from renewable sources.

Can site managers capitalize on renewable energy inputs to optimize energy consumption?

Capitalizing On Peak and Off-Peak Demand and Availability

Building technologies are changing at a fast pace. The rise of smart systems has made it possible for site managers to control buildings from afar, but what if such systems could be taken further and tweaked to optimize a site’s energy resources?

It’s not a new concept, but what is new is how building managers are using those technologies in response to changes in the power grid, specifically, power that comes from renewable sources. The biggest change comes in the way we think about buildings. Instead of managing demand to fulfill the load requirements of buildings and still conserve energy, building managers are now starting to think about how they can adapt to grids with high amounts of renewable energy or even sites that have on-site renewable power sources.

Renewable energy often operates in spurts, with different days or times of day generating more power than others. As opposed to peak shaving, some sites are planning their peak operating times around these times of peak renewables generation. The idea is that by utilizing renewable power when it is at peak production, sites will realize cost savings.

It’s similar to the concept of running your most power-heavy equipment at off-peak times to benefit from off-peak rates. The trick is figuring out when renewable energy will peak and aligning your demand around those times.

Pricing Plans Are Key

Pinpointing when and how to run peak loads at times of high renewable inputs requires understanding a site’s energy data and consumption patterns as well as knowing when different energy sources are available and shifting site operations appropriately.

There are three pieces of information that can help you gauge when it’s a good time to capitalize on renewable inputs:

Forecast load for buildings.

Weather forecasts.

Time of day pricing estimates.

Time of day pricing is critical to this form of energy management to work. Without it, there are no peak and off-peak pricing differences; you’ll pay the same rate no matter what time of day it is and regardless of how strong the sun is shining down at the solar farm.


It’s possible that as the U.S. energy grid adapts to add more renewables, energy providers will adapt their pricing structures as well to include more time of day pricing options. When that happens, there will be incredible potential for site managers to benefit from systems that automatically adjust a building’s energy consumption, and boost overall efficiency.

When It Comes To Commercial Diesel Generators, The Best Defense Is A Good Offense

By | Critical Power Products & Services, Generators

Remember that old saying, the best defense is a good offense? The same is true for commercial diesel generators. Being prepared when outages hit is crucial for your company’s survival.

Hurricanes, tornadoes, floods or even human error means infrastructure damage, among other damage. In some cases, services are completely destroyed or non-functional once water has receded or the debris is cleared. It may also take days or even weeks for repair and clean-up crews to show up. Depending on the severity, it may not even be safe for them to show up, so count on there being a long wait for infrastructure repair. Arming yourself with a commercial diesel generator is your company’s best defense (and offense) against power outages due to infrastructure damage.

1. Finding The Right Commercial Diesel Generator – There are a couple of factors to consider when you purchase a generator. First, consider the size of your company. Then consider how much and what kind of equipment you’re supporting. Are you supporting data center equipment or are you supporting hospital equipment that is critical to stay on?

2. Here Are Some Other Factors To Consider – Do you want to restore your company to full power, do you want emergency power, or enhanced emergency power with most basic, but some non-basic functions restored? This will determine the size and type of commercial diesel generator you buy.1100 kW CAT Diesel Generator side view

3. Find A Commercial Diesel Generator Retainer You Can Trust – Your next move should be to contact a commercial generator retailer you can trust. They will guide you through the process of buying the right generator to power your business when the infrastructure is down. They’ll make sure to match your business with a generator that offers the right amount of power output, and a bit extra, so your generator can grow with your company.

The Final Countdown: 4 Steps To A Seamless Data Center Demolition

By | Critical Power Products & Services, Equipment Disposal, Hazardous Waste Disposal, Recycle Equipment

Is your company migrating to a cloud? Are you consolidating? Are you relocating or collocating? Either way, you’ll need to start the process of eliminating obsolete and unneeded equipment from your current data center. This begins with an IT asset disposition or ITAD plan. Making an ITAD plan can help you to responsibly dispose of or recycle the data center equipment you don’t need.

Managing Your ITAD Plan

Data center demolition requires a detailed ITAD plan, whether you’re completely overhauling your system, or just consolidating for efficiency. Here are some helpful steps to planning your ITAD strategy.

1. Identify What You Need To Dispose Of And center pic for webiste

Here’s where it’s important to hire a company that offers proper disposal, recycling and data sanitation services. You need to reconfigure and consolidate to maintain efficiency, but you should never sacrifice security to do it.

2. Off-Site Or On-Site Data Wiping?

Your ITAD plan should involve data wiping, but should that data be wiped on-site or off-site? On-site data wiping is more expensive but allows you to oversee the process. Off-site is less costly, however, you cannot oversee the process, but you do receive verification. This decision all depends on how much you trust your data center demolition company and the sensitivity of the information your company stores.

3. Write Your Plan Down

Your ITAD strategy should be written and detailed. It should have a beginning, middle and most importantly, an end. Many times, if you haven’t planned your data center demolition, the process can drag on. This can cost precious time and money.

4. Find A Trusted ITAD Company That Can Take On Your Data Center Demolition

Finding an ITAD company you can trust for your data center demolition is fundamental. Make sure your ITAD company offers environmentally responsible practices, recycling, reselling of refurbished equipment (for you to sell, as well as buy) and a long history of excellent customer service. Remember, communication is key, so if they don’t have good customer service, it can be challenging to communicate your plan or voice your concerns.

This is the second of a two-part series to walk you through the process of selling your used industrial generator. As we mentioned in the first installment, finding a reputable vendor that not only offers excellent customer service but offers an appraisal is key. This will help you to price your used industrial generator. Here are some other tips that can help your vendor appraise your generator, so you can easily price and sell it.

Accurate Information And Description Makes Pricing Easier

It’s often difficult to determine a fair price for your used industrial generator. Many of us have no idea what to charge or how to find comparably priced generators. This is why the appraisal is so critical. In order to get an accurate appraisal, be sure to include these items in the description, either as a photo, written or both.

You Should Include:

  • The Basic Requirements, Including Hose Types, Coupling Types, Maintenance Requirements, And Fuel Tank Requirements
  • The Decibel Level When It’s Running
  • Whether It’s Still Under Warranty
  • The Kilowatts
  • The Maximum Capacity Load
  • The Last Time The Load Bearing Was Tested
  • The Generator’s Brand
  • The Generator’s Age
  • Whether It Has An 1800 Rpm Or 3600 Rpm Motor
  • Whether It Was A Backup Generator Or For Primary Use
  • What Kind Of Fuel Or Fuels It Can Use
  • Whether It Has Liquid Or Air Cooling Systems
  • The Number Of Previous Owners, If There Are Any Other Than You
  • Where You Had It Installed
  • Whether It’s An Outdoor Generator Or An Indoor Generator
  • A List Of Special Features, Like Alarms And Indicators

You should also offer the vendor your repair history. They will often determine if whether to provide it with by request or on the actual listing itself. You should

include the transfer switch and/or electronic panel and whether the installation will be included in the price. Offer your vendor a link to your used industrial generator’s manual. Regardless of whether they post it on the listing, having it on hand for potential customers is a plus. Plus, if you haven’t gotten your generator load tested recently, you should. Many vendors require it for large and expensive generators.

Always Answer Questions Quickly

Many buyers are interested because their business immediately needs a used industrial generator. Whether you’re their first or their hundredth pick; when they ask a question, make sure yours is the first answer they receive, especially if the inquiry has to go through a third-party website, which takes a little more time. Fast responses equal fast sales.

Critical Power’s Guide To Listing Used Industrial Generators Part 1: Getting Started

By | Critical Power Products & Services, Recycle Equipment

Sometimes selling used industrial generators can be just as stressful as buying them. The first thing your company should do is to find a reputable vendor who will allow you to post your generator. You’ll want to use a vendor that explicitly sells generators, coolers, chillers and other equipment. Sites like eBay are too generalized, and sites like Craigslist can be too sketchy. Find a site with a good reputation, reliable customer service, and an online appraisal service. Once you’ve done that, follow these tips to help you get the process of selling your generator started. Then, see the Part 2 of this series. 

Determine When Your Generator Needs To Be Sold

The first question you should always ask when you decide to sell a generator or any piece of equipment is: How much time do we have to sell it? This will determine many, many decisions in the selling process. If you have a limited time to sell, then it’s more important than ever to pair up with a well-connected vendor, like Critical Power. If your used industrial generators are being showcased on an industry leader’s website, you’re more likely to sell faster. They can connect you with the right kinds of buyers and the right types of businesses.

Take Good Photos

It’s true, a picture can speak 1,000 words. This is why most listings without pictures often get skipped over. People get skeptical and apprehensive when they can’t see the product in front of them. Here are some tips on how to take pictures of the generator you want to sell.

Include A Photo Of:

  • The Front
  • The Back (If You Can Take The Photo Safely)
  • The Product Identification Number
  • The Rubber Pads, Trailers Or Skids
  • The Voltage Stamp
  • The Hour Meter
  • The Engine ID Tag
  • The Generator In Its Enclosure
  • The Engine, Close Up
  • The Battery Panel, The Block Panel, Or Transfer Switch
  • The Brand Stamp
  • Any Extras That Come With It, Like Emergency Stop Buttons Or Alarms

Make sure your photos are clear, and all words are legible. Clear photos are honest photos, it means that there are no filters and your generator has nothing to hide.

How Smart Power Distribution Units (PDUs) Help Bitcoin And Cryptocurrency Miners

By | Critical Power Products & Services

Bitcoin was the beginning of cryptocurrency. It was no small feat that the invention of Bitcoin inspired the creation of the wide variety of cryptocurrency available today. In fact, there are over 900 different cryptocurrencies in existence today.

How Is Cryptocurrency Made?

Cryptocurrency is created by a process called “mining,” which isn’t mining in the traditional sense, but its similar in the sense that it is a repetitive process that eventually yields currency. In a nutshell, cryptocurrency miners need to confirm every Bitcoin or alternative coin transaction and add it to a blockchain, which is far different from descending a mine shaft! The blockchain verification is often coupled with difficult mathematical equations that the miner must solve. And, it’s not as easy as it sounds, which is why most of us trade cryptocurrency instead of mining it.

How Can Smart PDUs Help The Mining Process?

Since cryptocurrency mining can be power intensive, it can drive up electricity costs tremendously. Smart power distribution units can help you to monitor connected equipment so you can manage power usage. Monitored or switched PDUs work best in this situation because they can remotely monitor through an Ethernet network. You can even be notified of events through automatic alerts.

Smart PDUs Can Monitor Current Remotely

Smart power distribution units monitor power remotely through a feature called a load meter. Miners can see power usage, data and event logs in real time, which can help you to be a more efficient cryptocurrency miner. 

When your load levels are high a smart power distribution unit sends alerts to prevent downtime and other potentially expensive events. The best part is, you don’t have to be there in person when you’re mining in order to adjust your load.

Using a switched PDU allows you to monitor the amps you transmit through each outlet. Although not remotely, this allows you to switch around your connected equipment. Or, if you’re monitoring remotely, you can shut down unused outlets until you can physically be there to reconfigure them.

Smart PDUs Open Doors For New Cryptocurrency Miners

Smart PDUs allow people who have jobs or other obligations to manage cryptocurrency mining, making it more accessible to more people. Critical Power Products and Services is making smart PDUs more accessible, by offering a wide variety of used PDUs. Contact Critical Power for more information on how smart power distribution unit or smart PDU can help you mine the next big cryptocurrency coin and help you manage your energy use at the same time.

Data Centers 101: An Introduction To The Uninterruptible Power Supply

By | Backup power, Critical Power Products & Services, Uninterrupted Power supply

If your company has a computer system or a data center, meet your new best friend, the uninterruptible power supply. An uninterruptible power supply, what’s that? It is only one of the most essential components of your data center. Also called UPS, it provides essential power during blackouts, brownouts and any weather-related or accident related power outage. An uninterruptible power supply does exactly what the name suggests, offers uninterrupted power to the devices it’s attached to. So, no matter the circumstance, your essential devices will always be running.

What’s In A Name?

The uninterruptible power supply goes by a few different names, which mean essentially the same thing. Common terms that are interchangeable with the term uninterruptible power supply are:

  • Battery Backup
  • Power Backup
  • UPS Backup
  • Uninterruptible Power Source
  • Uninterrupted Power Supply

Most people in the data center and computer industries use the abbreviated version of Uninterruptible Power Supply and just say UPS. They don’t say it like the word “up”, they spell out each letter, like this: “you-pea-ess”.  So when you hear your computer tech or data center tech person say “U-P-S” you’ll know what they’re referring to.

What Do UPS’s Support?

UPS’s support much of the essential equipment that keeps your business alive. Here are some of the many devices your UPS can support:

  • Computers
  • ATM
  • ABM
  • Servers
  • Data Centers
  • VoIP
  • PBX
  • Phone System
  • Other Telecom Equipment
  • Heart Lung Machines
  • Dialysis Machines
  • Other Lifesaving Medical Equipment
  • Cash Registers
  • Debit Machines
  • Other Point Of Sale Equipment

A UPS Keeps The Heart Of Your Business Beating

These are just a few of the many examples of what a UPS can support. Essentially your UPS supports any equipment that cannot lose power, whether it’s sustaining a person’s life, sustaining the security of your computer, or keeping essential lines of communication open. And, UPS’s are everywhere, in hospitals, in supermarkets, in retail businesses, banks, data centers and so much more. If you haven’t noticed them before, you’re sure to notice them now. Imagine them as a pacemaker for essential electronics, when power fails, they kick in to keep the heart of health centers, businesses alive.

Make Cooling Costs And PUE Part Of Your Data Center Decommissioning Decision

By | Critical Power Products & Services, Data Centers

As your company grows, you increase your demands on your current data center. At this point, your equipment becomes less and less efficient. It’s important to calculate your power usage effectiveness ratio (or PUE ratio) and your cooling costs, so you can determine how efficient your data center really is. Calculating

 cooling costs and your PUE ratio can help you make the decision to relocate or begin data center decommissioning, relocation or demolition.

What Is A PUE Ratio?

Power and cooling costs make up nearly one-quarter of a data center’s budget. That can add up to a lot of money annually. This combined with the power usage effectiveness ratio can wreak havoc on your data center budget.

According to government standards, a 1.0 is an ideal and efficient PUE, with a realistic goal of 1.5 or less. When we calculate PUE, we divide Total Facility Energy by the IT Equipment Energy. This should equal one plus the non-IT generated energy over the IT generated energy. If this sounds complicated, you can ask your data center relocation company for help calculating.

Your current data center configuration may have been efficient enough when your company began, but it’s likely that it’s in desperate need of an overhaul. Overworked data center equipment coupled with outdated airflow management can create a higher than recommended PUE and increased cooling costs. This will cost your company excessive amounts of money over the years.

Lowering Your PUE Ratio Can Save Your Company A Lot Of Money

It may not seem like much, but if a data center decommissioning or relocation can lower your PUE ratio by just .25 percent, your company can potentially save millions. One way to reduce your PUE ratio is to move your data center to an area with a naturally cooler climate. This will reduce cooling costs and non-IT generated energy costs because Mother Nature will be doing some of the cooling for you. Also relocating to a less urban area with lower energy prices can help. And, of course, updating to high-density modules with more efficient airflow is a must.

A Reputable Company That Offers Data Center Decommissioning And Relocation Is Key

Critical Power Products and Services offers the full life cycle of data center decommissioning and relocation services. They understand how data center decommissioning can lower your PUE, saving your company in the long run.

Yikes! Wind Turbine Fire Under Investigation, Reinforces Necessity Of Routine Inspections

By | Critical Power Products & Services, Emergency Preparedness, Green

In early June a wind turbine caught fire in Iowa. The fire caused the blades to disconnect and fall to the ground. While the cause of the fire was still unknown at the time of this post, it looks like mechanical failure is to blame. The fire started in the nacelle of the turbine, which is where the generator and equipment is housed.

While we don’t know for sure what caused the fire, if the turbine had undergone recent repairs, or what its inspection schedule looked like, the incident is a stark reminder that routine machinery inspections are a necessary part of doing business.

Head Off Problems Before They Start

Routine inspections and regular maintenance can help prevent large-scale disasters, but just as importantly, they help prevent small problems from becoming big problems. Not only are smaller problems faster and easier to resolve, they’re often cheaper too.

A routine maintenance program will keep you informed of the overall health and performance of your machinery. You will be able to track which pieces are racking up more and more downtime or requiring repairs more frequently. Use this information to help plan out a replacement timeframe and develop your capital equipment budgets.

As you begin to invest more and more time and money into maintaining old equipment, eventually the costs will outweigh the benefits and you will have a solid case for selling old equipment and purchasing new.

Is It Time To Revisit Your Maintenance Plan?

When was the last time your maintenance program was revised? Do you even have a plan in place? Developing an equipment maintenance plan (EMP) takes work at the outset, but once the plan has been developed, it simplifies processes and procedures and reduces your business’ risk exposure.

EMPs don’t have to be complex. At their most basic, EMPs are simple tables that list the piece of equipment and its’ routine maintenance tasks. You’ll also want to include the frequency of each task and if any special tools or considerations are required to perform the task. Special considerations might be whether the unit must be shut down or if it remains running during the task. More complex EMPs include the amount of time spent on each task so you can track how much time you are devoting to maintenance.

Hopefully, you’ll never find yourself in a situation where a piece of equipment catches fire and is destroyed like the wind turbine in Iowa, but if you do, a look back at your maintenance plan can help prove to insurance adjusters that you were doing everything possible to avoid such a catastrophe.
