Enclosures, what's inside them and a few serious circumstances

You may be looking that this is about landowners (see enclosure in Wikipedia) in medieval times. No.

We will be talking about enclosures, in different dimensions, those that covers and protects business and public safety interests, and specifically, the equipment they use and run to serve their customers and the society, respectively. Interdependent relationships among the living and the materials they create must be factored in, everything we do, as our bottom line, and a multi-generational sustainability program. Of course, we need not only enclosure and professional people, we have to bring everyone, to design such good sustainability initiative, beyond that green technology. We must start somewhere else, do the right thing we can without compromise. Rack the brain, extend abilities and coordination further, and never settle on short-term reward. We should do better, this is possible now.

Careful, though, dilettantes, technology averse, aesthetics and nature trail people call enclosures, utility boxes. Depending on how and where it was constructed, their mere presence may endlessly annoy them, may even bring lawsuits against those who erected them, with or without permit from the government.  

What can be found inside are digital and analog devices, or computers, general purpose servers, workstations, cloud, very focused high performance compute, artificial intelligence, and those that are limited in form and function including Internet-of-Things. We must also include electronics, electrical modules or power distribution units, telecommunications' circuits and base stations, and even mechanical as well as robotics components. All of these are only going to increase.

Enclosures also make up most of the growing deployment of edge data centers which, in a very special circumstances, are positioned and located external of offices and buildings, in harsh environment.

Like for instance, visible to public are the legacy infrastructure of Plain Old Telephone System. They were the first few that used enclosures, and they are still around from where they were before. Some nations have strict regulations and laws for safety of communications infrastructure which makes, if not mandates, providers to really have to used enclosures that helps deliver the upkeep of physical security requirement. Now we are seeing different types and sizes of enclosures as they house not only devices but variants of circuits and terminations of interconnected glands, wires and cables.

Enclosures with the above materials are installed, DIN rail shifted/slid, screwed, wired, bound, seated and stuck to utility poles, walls, on top of concretes, pavements and they house the build of, and help extend, connections where services, like for instance electricity and internet, should be brought to, usually homes, offices and industrial complexes. All used and done with their correct mechanisms. Speaking of industrial and manufacturing settings, the regular fixtures of heating, ventilation and air-conditioning are also housed in enclosures which, an unsuspecting eye or anyone without any idea at all, could simply imagine a wall and exhaust are over there. 

As you can see in the homepage, the material build in an enclosure is important for different requirements of installations.

Enclosure use cases

Universal enclosures suited to outdoors, underground, critical, severe, hazardous and risk zones, can even be designed to withstand bombs, for embedded electrical, power, batteries, thermal, water distribution, electronic, telecommunication and computing facilities

Enclosures for servers, data/command center, collocation from rack, blade (often called sheet metal, chassis, vendors' stanch construct) and custom-made installations

Enclosures for supervisory control and data acquisition (SCADA), industrial automation and control, smart meters and home devices, climate control, heating, ventilation, air conditioners (HVAC) and thermoelectric coolers

Enclosures for food and beverage processing plants including but not limited to healthy, safety and hygienic requirements

Enclosures for art, craft, creative, museum archives and exhibits
