While it may be tempting to think that all computers are created equal, this simply is not the case. Every computer is built for a specific purpose whether or not it is labeled as such. Industrial grade computers are computers that are designed for industrial applications like manufacturing and oil processing. Industrial grade computers differ from commercial computers in a number of ways that make them more versatile and well suited for industrial use.
Industrial Computer Applications
The biggest difference between an industrial computer and a commercial computer is in their applications. A commercial computer is generally designed for use in an office setting. This allows for commercial computers to be built less ruggedly than industrial grade computers. Commercial computers also have the benefit of working in air conditioned spaces, meaning that they do not have to use advanced cooling systems. Commercial computers also do not have to operate on a 24/7 basis, meaning that they can be built to consume more power.
Each industrial computer is designed to handle situations that a commercial computer simply could not. Take the Rugged Mini E3 by Tangent for instance. With a rugged, shock and vibration rated chassis, the Rugged Mini E3 industrial computer is capable of being used in nearly every industrial setting. In manufacturing, this industrial grade computer’s extreme temperature operating range from -13°F to as hot as 158°F means that it can handle nearly every environment. With an advanced, fanless cooling system, the Rugged Mini E3 is able to operate on a 24/7 basis without needing to be dusted constantly.
Longer Lifetime In Harsher Environments
Because commercial computers are used in the same environments as people, they are able to be built with less stringent guidelines than industrial grade computers. While this may be fine for use in the office, this simply would not do on an oil drilling platform off the coast. Industrial grade computers are built rugged, smart, and to last. With industrial grade computers like the Rugged Mini O from Tangent, there is virtually no worrying about if your computer system will hold up.
The Rugged Mini O industrial computer is built to the toughest specifications possible. With an IP69K fully waterproof enclosure, this industrial grade computer can be used virtually anywhere. A solid state drive allows the Rugged Mini O to operate in areas where vibration and shock would render lesser computers worthless.
Versatile And Customizable
Tangent’s entire lineup of rugged industrial grade computers has the ability to help your industrial facility run longer and more productively. With industrial computers as small as a book to ones as powerful as industrial workstations, there’s an industrial grade computer that will fit your need perfectly.
Despite everything that is happening, many businesses are still open. Essential businesses are the backbone of our nation’s collective public health effort, and supplying them with the equipment they need is crucial to keeping the U.S. afloat. Critical manufacturing, chemical production, and food production have all been deemed essential, and Tangent remains committed to helping these industries that help us all.It is this commitment that drives Tangent to continue to produce high quality industrial grade computers for essential industries and essential businesses.
All-In-One PC: An Industrial Grade Computer For Essential Industries
There are a broad range of industries that fall under the label of critical infrastructure, but they all have something in common: they can benefit from the use of an All-In-One PC. Every All-In-One PC is built with industries like food processing, metal fabrication, and oil processing in mind.
Every All-In-One PC by Tangent is an Industrial Grade Computer. This means that each All-In-One PC can handle the rugged environment of an industrial facility.

There’s no doubt that Industrial PCs are a vital part of every industrial facility. But sometimes, for various reasons, a smaller approach may be preferred. That’s where Mini PCs from Tangent come in. Mini PCs are Industrial PCs that come in small yet powerful form. Rugged Mini PCs are perfect for situations where space is of the utmost concern, but powerful processing power is still required. At Tangent, our lineup of Mini PCs are built for the most demanding applications practiced—whether that’s inside or outside the factory.
High Performance Mini PCs
Embedded control systems don’t have to be tethered to large Industrial PCs. With high performance Rugged Mini PCs from Tangent, embedded control systems can run on a small yet powerful device directly adjacent to the system being controlled. Whether it’s suspension or fluid levels, there’s a Rugged Mini PC from Tangent that can control it. Rugged Mini PCs like the Rugged Mini O from Tangent are IP69K certified waterproof and can withstand temperatures from -4°F – 140°F, making it the perfect controller for nearly every application.
Fanless Mini PCs
Digital Signs are not an industrial endeavor, but nevertheless experience industrial grade conditions. Digital signs posted outside can be exposed to sun damage, dust, and blistering hot summer days. In order to keep these signs running, Tangent has designed Rugged Mini PCs like the Rugged Mini L2 to be fanless, thus making them perfect for digital signage. Without fans, there is no risk of dust buildup in the Rugged Mini PCs, allowing it to withstand all the rigors of outdoor life without constant maintenance.
Interactive Kiosks can face similar problems when exposed in the elements. Even more so when these Kiosks offer the user a touchscreen interface. In order to keep these Kiosks from quickly being worn out by daily use, employing Mini PCs from Tangent is crucial. Mini PCs like the Rugged Mini Tank ensures that your kiosk, quite literally, will be built like a tank.

With Mini Industrial PCs from tangent, there is nothing that can’t be done with industrial efficiency.
When it comes to the needs of industrial facilities, no two sets of needs are alike. Every type of facility— from factories, to oil processing plants, and even refrigerated facilities—has its own unique set of problems requiring unique solutions. Tangent is highly aware of this, and has designed multiple industrial computers to meet the needs of many facilities. Our feature packed industrial computers are custom designed for nearly every environment, guaranteeing there are multiple Tangent industrial computers to meet the demands of your facility.
Flexible Mounting Options
Not every facility has the square footage to accommodate multiple office spaces, but this shouldn’t mean that you have to sacrifice your workstations altogether. Industrial computers from Tangent like the F15 industrial grade computer are built for just such instances. With flexible VESA 75/100 and M8 Heavy-duty screws mounting options, the F15 industrial grade computer is capable of being placed nearly anywhere. The F15 industrial grade computer is an all-in-one PC that does not require a mouse or keyboard, meaning that it also does not require a large desk. Simply mount the F15 anywhere—even on a forklift—and “anywhere” can become an industrial workstation.
Military Grade Hardware
While other manufacturers claim to have “military grade” industrial computers, Tangent has actually gone through the accreditation process for its line of qualifying industrial grade computers. Industrial computers like the Rugged Mini Tank industrial computer meet MIL-STD-810F shock standards. This makes this industrial grade computer the perfect fit for industrial areas where vibrations and drops are a fact of life. The Rugged Mini Tank lives up to its name, and can withstand military levels of punishment while operating as though it was sitting in a coffee shop.
Advanced Cooling Systems
It is true that not every industrial facility’s needs are the same, but one thing holds true across the board: industrial facilities require industrial computers with specialized cooling systems. Traditional fan based cooling systems used by commercial computers assume that the location they are used in will have an air filter to remove dust and other contaminants. It goes without saying that this is not the case in industrial facilities. Tangent has created a passive cooling system for its lineup of industrial grade computers that not only cool them off, but allow them an extreme resistance to temperatures.
Industrial computers like the Rugged Mini C from Tangent can withstand temperatures from -40° – 185°F. This extreme range of operating temperatures makes the Rugged Mini C ideal for facilities where temperatures are either ice cold or beating hot.
Feature Packed And Factory Ready
Industrial grade computers from Tangent are custom designed to meet the needs of every industrial facility. Whether your facility lacks space, requires military grade hardware, or even has extreme temperatures, Tangent has created an industrial computer that will be the perfect fit.
As the U.S. industrial sector continues to expand, factories are looking for new ways to beat the competition in terms of efficiency and productivity. This may mean that creating multiple shifts and transitioning your facility to operate around the clock is in your factory’s future. But even if your workers can operate in three separate shifts, their equipment cannot. Making sure that the equipment your workers use can withstand 24/7 use is crucial to maximizing your facility’s productivity and efficiency.
Industrial Computers Built For 24/7 Use
Industrial computers are computers custom-designed to operate in factories, oil rigs, and every other industrial facility currently in use. Unlike commercial grade computers, industrial computers are able to withstand the temperatures and environments of the industrial sector with ease. But not all industrial computers are built equal. Industrial computers are seldom designed to operate on a 24/7 schedule—unless they are designed by Tangent. Tangent designs all of their industrial computers to be able to withstand a 24/7 use cycle with ease. Here’s how:
All-In-One PC Housing
In order to maintain a 24/7 use cycle, industrial computers need to be designed accordingly. One way to accomplish this is design the industrial computer as an all-in-one PC. All-in-one PCs are industrial computers that are similar to tablets in that the entire PC is contained behind the screen. All-in-one PCs like the S Series from Tangent make full use of this technology in their design. The S Series, when equipped with a solid state drive, features no moving parts whatsoever. In addition to its touchscreen, this means that the S Series rarely requires maintenance, making it perfect for 24/7 use.
Extreme Temperature Resistance
A 24/7 use cycle means that an industrial computer must be able to withstand wide ranges of temperatures. From chilly nights to scorching days, the F15 all-in-one PC from Tangent can do just that. Able to withstand temperatures ranging from -4 – 140°F, this all-in-one PC is ready for any environment. Even when used on an oil processing facility under the desert sun, the F15 will run as though it was positioned in an air conditioned office.

When making a new network for your facility, there are many things to consider. Should you invest in smart factory infrastructure entirely? How many networks should your factory have? How many switches and routers do you need? While these are some of the most pressing questions, the question of the actual computers that will comprise the network should not be overlooked. While traditional computers rely on switches to create a network across multiple computers, there are other options that can be more effective. Industrial computers from Tangent can create networks via switches or simply by being connected to one another, allowing for more choices in your network building process.
Industrial Computers Are Perfect For Complex Systems
Complex networks require advanced infrastructure, and industrial computers from Tangent are more than advanced enough to be the building blocks for your factory’s network. Tangent’s lineup of rugged computers are built for the factory setting. These rugged computers can withstand temperatures from -40°F to 185°F with ease, making them perfect for nearly any facility.
In addition to this wide operating temperature range, rugged computers from Tangent are specially designed for every industrial need, including the creation of complex networks. Every rugged computer from tangent has, at minimum, two Ethernet ports. This allows Tangent’s rugged computers to connect to two networks at once, allowing for the daisy chaining of rugged computers.
More Ethernet Ports: More Networks
While it is common to see the use of centralized networks in most facilities, the use of decentralized networks is not to be ignored. Decentralized networks differ from centralized networks in that instead of every computer being connected to one network, computers are networked to each other directly. This has distinct advantages in certain situations, namely that a large bandwidth use by one computer does not slow the whole network down.
One way to accomplish a decentralized network is with industrial computers from Tangent. Rugged computers like the Rugged Mini FX come standard with four separate Ethernet ports. With four Ethernet pots, this rugged computer can connect to four separate networks. This means that it can potentially connect to four other industrial computers, which are all in turn connected to three other computers, and so on. Or, the Rugged Mini FX can connect to three industrial computers and a separate, centralized network. The possibilities with multiple Ethernet ports are endless.
If four Ethernet ports are not enough for your complex system needs, then the Rugged Mini C from Tangent is the way to go. This industrial computer has a whopping six Ethernet ports. This nearly absurd amount of Ethernet ports allows the Rugged Mini C to potentially connect to six separate networks. With an optional solid state drive, this industrial computer can make the most out of its six Ethernet ports.
Complex Systems Don’t Have To Be A Complex Headache
With industrial computers from Tangent, creating complex systems doesn’t have to be a chore. Industrial computers can help you create complex networks that are ready to help your facility transition into a smart factory.
While some industrial spaces restrict the amount of dust circulating throughout the facility, the matter of the fact is that most industrial facilities harbor dust and other pollutants. While workers can easily avoid this dust, their industrial computers may not be as lucky. Typical industrial computers require outside air be brought into the case in order to cool off the delicate central processing units (CPUs), normally via a fan based cooling system. Without proper cooling, CPUs can overheat, rendering the entire industrial computer useless.
However, the very same system that preserves the integrity of the CPU can actually cause long term harm as well. Fan based cooling systems excel in environments where air is filtered on a regular basis, such as in offices or at home, but falter when used in dusty environments. CPUs are cooled when their fans pass cool air through what is known as a heat sink, which appears as a metal comb elongated so that it’s teeth are inches wide. Typically, heat transfers from the CPU to the teeth of the heat sink, where cool air circulated by the fan removes the heat from the heat sink to the outside of the case.
In a dusty environment, the air brought in by the industrial computer’s fan slowly builds up along the channels between the heat sink’s teeth. Overtime, the heatsink’s channels begin to be impassable to fresh air, and the heatsink has no way of expelling heat. The heatsink continuously heats up, and eventually the excess heat begins damaging the CPU.
Fanless Computers: Working Where Others Can’t
Fanless computers are an elegant solution to this conundrum, circulating no air throughout the body of the industrial computer. Without a fan, no dust builds up in the industrial computer and it remains functional even in the dustiest of environments. Fanless computers function in the same way traditional industrial computers operate, except that they feature a passive cooling system.
This passive cooling system is just as, if not more, reliable than fan based cooling systems without opening up the industrial computer to the dusty environment it exists in. The industrial PC fanless solution solves one of the biggest problems for industrial computers, opening them up to a wider range of use.
Industrial PC Fanless Solution: Rugged Mini E3
Without a fan, the Rugged Mini E3 from Tangent makes full use of the industrial PC fanless solution. Capable of working environments where temperatures can reach up to a scorching 158°F, the Rugged Mini E3 is one fanless computer that proves fans are not necessary to maintain proper cooling.

With such a wide variety of high performance industrial computers, there is sure to be one that solves a problem in your facility. High performance industrial PCs from Tangent are purpose built to serve workers in every field when traditional commercial grade computers simply will not do.
When shopping for new industrial PCs, there are many important factors to consider. CPU age and clock speed, hard drive space, and availability of I/O ports are all crucial considerations to make when deciding on the equipment that will keep your facility running in the years to come. But one critical, and usually overlooked, aspect of industrial PCs to consider when purchasing a new setup is the amount of random access memory (RAM) they contain.
What Is RAM In An Industrial PC?
When we think of an Industrial PC, we like to imagine one tower that does everything itself. But this is actually not the case, and even in the smallest microcontrollers different components make up the larger computer. RAM serves a secondary storage for your computer alongside your hard drive, but has a specific task. Instead of saving data such as programs and files on a long term basis, RAM is actually empty when the computer is not in use. When you use a program, such as autoCAD, Premiere Pro, or even SOLIDWORKS, on your industrial PC the program is copied from the hard drive to the RAM. Hard drives have a certain amount of data they can transfer around the Industrial PC every second, and RAM has a much higher rate of data transfer; Therefore RAM allows for programs, files, and data in use to be easily accessed by the industrial PC for immediate use.
How Much RAM Do I Need In My Industrial PC?
While everyone’s industrial PC needs vary, a good rule of thumb when looking at RAM is: The more, the better. There simply is no real drawbacks to having as much RAM as possible, as more RAM allows more programs, files, and data to be in use at once on your Industrial PC. However, there is a minimum amount of RAM for many programs that should be beared in mind. For instance, SOLIDWORKS requires a minimum of 16 gigabytes (gb) of RAM to function and 32 gb to work optimally. The Rugged Mini E3 from Tangent can be configured to both a 16 gb and 32 gb amount of RAM, enabling this industrial PC to function as a standalone SOLIDWORKS workstation or general use station. Every program should have a minimum system requirements section listed on its software page which will tell you how much RAM is needed for the program.
Why Should My Industrial PC Have More Ram Than It Needs?
As technology progresses, the file sizes of programs are getting bigger, and require more computing power to handle. SOLIDWORKS now recommends the use of solid state drives over hard drives due to their significantly faster data transfer speeds. Having more RAM than is required for programs is an easy way to future-proof your industrial PC purchase. In the short run, a larger pool of RAM allows your industrial PC to multitask, running multiple industrial software at once. In the long run, your industrial PC will still be able to handle the new, updated industrial software without needing an upgrade itself.
RAM In Industrial PCs
Whether you put the maximum or minimum amount of RAM in your industrial PCs, it is important to understand what RAM does and make an informed decision on the matter. Tangent industrial PCs have a wide range of RAM options, from 4gb up to 32 gb, allowing you to make the best decision possible for your facility.
