The Difference Between Reactive, Preventive, and Predictive Maintenance
Asset maintenance is the inescapable part of any factory floor. In 2020, nearly 47% of factories in the US spent between 21% to 40% of their operating budget on maintaining their equipment.
That is quite the money sink.
This is specially made more egregious by the fact that US companies use almost $40 billion in outdated equipment, which is believed to be the leading cause of unplanned downtime.
With that said, it is then no wonder that maintenance is such a hot topic, especially when it comes to the costs, efficiency, and downtimes related to it.
In this article, we’re going to address those questions precisely. In the text below, you’ll find the analysis of the benefits of the three most frequently-used maintenance types, as well as their drawbacks.
Reactive Maintenance – What is It?
Reactive maintenance, also known as corrective maintenance, is the most basic type of upkeep of equipment. It centers around performing corrective work on assets that have already broken down, fixing them, and bringing them up to speed.
The biggest advantage of this kind of maintenance lies in its relatively low operational cost. Considering the machine is fixed only once it breaks down, you only need to pay once, and you only need to suffer downtime once.
However, this is also corrective maintenance’s greatest weakness. See, the idea of fixing machines only once they break hinges on keeping the asset running for as long as possible and generating as much production from it as possible.
Once the machine breaks, however, now you’re faced with unplanned downtime and costs that could easily exceed the revenue generated by the machine, which, in turn, has a majorly negative impact on that asset’s overall ROI.
Be that as it may, reactive maintenance is still essential. The truth of the matter is, that machines break down, sometimes unexpectedly, either due to insufficient maintenance, unskilled labor, or poor design in the first place. When that happens, you will have to shut down production for a while as you address the issue.
Preventive Maintenance – A Step Up?
Naturally, most companies will work hard on properly performing upkeep on their assets to keep them running for longer and to prevent unnecessary downtimes and the costs tied to it. This is why most businesses turn to preventive maintenance.
Preventive maintenance is a set of practices centered around performing regular, periodical maintenance of machines and assets within the factory.
As such, preventive maintenance already trumps reactive maintenance by eliminating unexpected downtimes. Needless to say, you still have to halt production to perform the said maintenance, but predicted downtime is much easier to work with and around than your assets suddenly breaking.
Basically, the goal of preventive maintenance is the preservation of assets in the long run. This is also why such upkeep has a very high ROI, reaching up to 545%, whereas corrective upkeep might even plunge you in the red.
That said, in order to reach that ROI, you also have to sink quite a bit of money and man-hours into it to be effective.
You see, the core of preventive maintenance is regular maintenance. This means that your machines will have to be inspected at certain predetermined intervals, and parts will be swapped out regardless of whether they’ve run their course or are still usable.
This also means that you have to have skilled staff on hand to perform all the necessary diagnostics and part replacement. All this drives up the cost while also increasing downtime due to the necessary taking assets off the production line to have them checked out.
In the end, though, regularly diagnosing and replacing parts still has much higher benefits than running your assets into the ground, then replacing them. As we said, preventive maintenance extends the life of your assets and keeps them running for longer, thus generating higher ROI despite increased planned downtimes.
Predictive Maintenance – The Ultimate Solution?
Predictive maintenance, as its name suggests, centers around predicting failure points and reacting to them before they occur.
As such, predictive maintenance encompasses the advantages of both of the previous types of upkeep in order to create the ultimate maintenance model for your business.
Ultimately, PdM seeks to:
Reduce maintenance costs
Reduce planned and unplanned downtimes
Increase the efficiency of maintenance
Increase asset life span
Increase the overall efficiency of the production line
By not having to devote man-hours and funds to a regular diagnostic cycle, you’re freeing up your staff to do other important things while also having more money at the end of the day to invest in other assets.
Also, because you’re still, technically, performing prescriptive maintenance by predicting failures and addressing them before they happen, you’re still not experiencing the dreaded unplanned downtime or having to replace your assets completely.
So, how does PdM do it?
The core of this methodology is the Industrial Internet of Things (IIoT). IIoT is the concept, developed from IoT (Internet of Things), of having “smart” machines and assets that “talk” to each other and their users and are all integrated into one overarching network.
Twenty, or even ten years ago, this was but a concept. However, with the recent advances in AI technology and machine learning, this concept has slowly become a reality. Now, machines can be connected and can be made to communicate, and they do it via sensors.
These sensors are at the heart of IIoT. They enable the gathering of various types of data that are then transferred over the network into a computer mainframe that analyzes this data, thus, effectively performing diagnostics in real-time.
This data can then be used to, well, make predictions about the possible failures of your machinery. If a parameter is out of predefined bounds, this points to a possible problem, and you can react to it before any major damage occurs.
However, this also has another advantage that the two previous models don’t have – the ability to detect the source of the problem.
You see, with reactive maintenance, you’re just fixing a machine that’s already broken, and with PtM you’re performing regular maintenance of parts. However, both of these models only aim to alleviate the problem, not eliminate it altogether.
Due to the abundance of sensors all communicating with each other and the amount of data they produce, you are able to pinpoint the exact problem in your production line that’s reflecting on certain asset(s) down the line. And, once you address that problem, you’re eliminating all others connected to it.
From all this, it would seem that PdM is the way of the future and is the only maintenance model worth considering. But, in truth, predictive maintenance still has enough kinks in its process that put companies off.
For starters, this is by far the costliest and most complex model to implement. In order to fully appreciate predictive maintenance, you would either have to build your factories from the ground up with PdM in mind or figure out a way to introduce it into your already established infrastructure.
On top of that, you also need specialized, highly-trained help. This help is still hard to find and relatively expensive to hire, which drives the overall costs of implementation further up.
Finally, you have to have specialized software to analyze the specific data tied to your industry or to even your production process. Metal industry software is going to differ from software required for running an automobile plant and so on. You’ll often have to have custom software made by outside experts, which all cost money and time.
In the end, while predictive maintenance seems like a clear winner due to all the benefits it brings, the implementation methods of the concept are still young. However, PdM is truly the way of the future, and, in the coming years, we are very likely to see this concept crop up within an increasing number of companies across the world.
That said, this does not make the other two methods completely obsolete. Reactive maintenance is still the cornerstone of maintenance in general, and the high ROI of PtM, as well as its commonality, still proves to be undeniably attractive to businesses that don’t have the means to create the infrastructure for predictive maintenance.

6 Things You Should Inspect When You Buy a Home
Purchasing a home is an exciting and big investment, but it’s crucial to thoroughly evaluate the house before committing. Any issues that can necessitate excessive repairs in the future might be found by doing a comprehensive check. This post will cover six important things to consider when buying a house.
6 Things You Should Inspect
Given that it supports the whole structure, a home’s foundations are one of its most crucial components. Look for any fractures or movement in the foundation that can point to structural problems. Indicators of foundation issues include dampness or water damage, so watch for them.
Another important part of a house is its roof, which shields the inside from the elements. Look for wear and tear, water damage, and missing or damaged shingles. Check the gutters for obstructions or damage since wet walls or a leaking roof might result from blocked gutters.
Assess the water pressure and look for leaks or corrosion in the pipes. Search for evidence of water damage near toilets, sinks, and showers. Verify that the water heater is in good operation and has received regular maintenance.
Inspect the panelboard for any wear or damage indications. Inspect the area for exposed wires or overloaded circuits. Make sure that all the outlets and switches are working properly.
Make sure the central air conditioner system is in working order by doing an inspection. Look for any dirt or debris in the filtration and ducts, which may indicate a lack of maintenance. Make that the system has received routine maintenance and is the appropriate size for the house.
Check the ceiling, flooring, and walls for any evidence of wear or damage. Check for drooping, water damage, or cracks. Inspect the doors and windows to ensure they are energy-efficient and working properly.
Why It Is Important to Inspect a House Before Buying
Buying a house is a big commitment; a full examination before you buy may save you a lot of trouble and money in the long run. Here are three reasons why you should check a property before purchasing it:
Identify Potential Issues
Any problems concealed or not immediately visible to the untrained eye might be found during a house inspection. Finding possible faults before you purchase might help you bargain for a lower price or keep you from buying a house with serious concerns.
Plan for Future Expenses
By pointing out any sections of the home that need immediate care or may eventually need repairs or replacements, an inspection may help you budget for upcoming costs. With this knowledge, you can plan your budget for house maintenance and repair expenses and avoid any unpleasant surprises after buying the property.
Ensure Safety and Security
By having it inspected, you can ensure a home is secure and safe for you and your family. Any safety risks, such as damaged electrical wiring, shaky construction, or mold that might endanger your and your family’s health and well-being, can be found during a comprehensive examination.
How to Inspect a House
Hire a Professional Inspector
Hiring a qualified inspector is the greatest approach to properly checking a home. A qualified inspector has the knowledge and tools to check every part of the home for any issues. They will examine the roof, the foundation, the plumbing, the HVAC system, and any other areas that could need repair.
Check for Structural Issues
It’s crucial to look for potential structural problems while assessing a home. Check for uneven flooring, cracked walls or foundation, and improperly closing doors. These can indicate a more serious structural issue that needs pricey repairs.
Look for Signs of Water Damage
Significant issues in a property can result from water damage, such as mildew growth and structural damage. Look for evidence of flood damage in the kitchen and bathroom, near doors and windows, and in the basement. Be looking for warped or damaged flooring, musty aromas, and water stains on the walls and ceilings.
In conclusion, checking these six important areas of a house will help you decide on a property wisely. You must employ a professional home inspector to undertake a complete inspection of the house and provide a detailed report on any potential problems. A thorough examination is an investment that may ultimately save you work, money, and hassles.
On Grid or Off Grid Solar System: Which one is better?
Photovoltaic systems are among the most in-demand applications when it comes to lowering carbon emissions and increasing the proportion of renewable energy in the grid. PV panels generate direct current (DC), which must be converted to alternating current (AC) before being connected to the grid and used locally or sent to faraway consumers. With solar inverters, DC may be transformed into AC.
Installing a solar energy system at your home or company but need help deciding between off-grid and on-grid panels? To make the best decision, learning about the fundamental difference between off-grid and on-grid solar systems is important.
What Is Off-Grid and On-Grid Solar Energy?
A solar energy system that is not attached to the utility grid is said to be “off-grid,” whereas a solar energy system that is attached to the utility grid is said to be “on-grid.” How you’re billed, what happens if the power grid goes down, and whether or not you have access to energy all depend on whether you have an off-grid or on-grid system.
The Differences Between Off-Grid and On-Grid Solar Energy
Electricity Access with Off-Grid Solar
Such systems solely rely on the sun’s energy and batteries to power homes or businesses. Without a backup generator, electricity is only available in two instances:
- When the sun is shining, the solar system generates electricity, and
- When electricity previously generated by the solar system is drawn from a storage device, such as batteries.
With energy storage, there will be sufficient electricity during cloudy days, and electricity will be available at night.
In an off-grid system, there is no surplus electricity available beyond what is generated and stored. Therefore, the electricity produced and stored is the only power source for your equipment, and no additional electricity is accessible if needed.
Electricity Access with On-Grid Solar
An on-grid solar system provides continuous access to electricity, regardless of the power output of the solar system or the presence of energy storage devices. However, the availability of electricity is subject to the grid’s uptime. When the solar system is not generating enough electricity to meet the energy demand of devices, machines, or lights, users can draw electricity from the utility grid as a supplement. This guarantees a reliable and uninterrupted source of electricity for all your needs.
Difference #2: What Happens to Excess Production
Excess Production with Off-Grid Solar
The amount of excess electricity your solar system generates depends on the system’s size, energy consumption, and when you use that energy. The management of this excess electricity relies on the type of equipment installed. Typically, off-grid solar systems are designed to produce a surplus of electricity during the daytime, stored in batteries. This stored energy is used when the system is not producing energy, such as at night or during cloudy weather.
Excess Production with On-Grid Solar
Like off-grid solar systems, individuals opt for on-grid solar systems also aim to satisfy their entire energy requirements or at least a significant portion. It’s feasible to attain this objective with on-grid systems as well.
Difference #3: What Happens When the Grid Goes Down
Power Outages with Off-Grid Systems
An off-grid solar system operates autonomously and doesn’t rely on the power grid. Hence, in a severe storm or power outage, your solar system will continue to function seamlessly, and you won’t experience any disruptions or changes in your electricity service.
Power Outages with Grid-Tied Systems
When your solar system is connected to the grid, you have uninterrupted access to electricity as and when required. However, you must also adhere to specific guidelines and regulations. When the grid is down, a grid-tied solar system will not provide electricity unless it has a battery backup.
The choice between off-grid and grid-tied solar systems largely depends on individual circumstances. Although off-grid systems offer complete independence from the utility, they can be comparatively costly. On the other hand, grid-tied systems provide substantial electricity savings and uninterrupted access to the grid, ensuring that you always have the necessary electricity to power your residence or business.
