Hot, Cold, Wet or Dusty? How Planning for the Environment Can Help You Deploy a Successful Network at the Edge
August 05, 2021
Does it snow, rain, rust or get really hot or cold? Sounds like a Broadway show tune, right?!
Whether you sing it or say it out loud, it’s an equally important question to ask and answer if you’re planning to deploy a successful network at the edge, where all the elements above and then some offer just a few logistical challenges and considerations.
And as you can likely imagine, a standard IT enclosure simply won’t be able to provide the appropriate levels of equipment protection you’ll need in more harsh indoor and/or outdoor environments. Conversely, an industrial enclosure specifically designed to withstand the elements can and will provide the primary protection of sensitive equipment in these nontraditional spaces.
But, what’s the real difference between industrial enclosures and standard IT enclosures anyway?
The main difference between the two enclosure types is that industrial enclosures are completely sealed to prevent ingress of dust and/or liquid.
Pro Tip: When it comes seals that offer the highest levels of equipment protection, look for a seal that is created using formed-in-place foam gasket technology. A robotic process applies this type of seal, and it is much more durable and reliable than adhesive-backed foam tape.
When you understand your environment(s), and are ready to select an enclosure, it will be important, prior to selection, to also understand NEMA and UL ratings, additional types and ratings meant to detail important differences in material build, type, location and more that all further help ensure you’ll select the appropriate enclosure for any nontraditional environment.
NEMA vs. UL
In the United States, the National Electrical Manufacturers Association (NEMA) identifies 16 types of enclosures for nonhazardous locations, each providing a different level of protection against dust and liquid penetration, in its “NEMA Standard 250 Enclosures for Electrical Equipment (1,000 V Maximum).”
Likewise, Underwriters Laboratories (UL®) has a similar system in “UL 50 Enclosures for Electrical Equipment, Non-Environmental Considerations; UL 50 Enclosures for Electrical Equipment, Environmental Considerations; and UL508A Standard for Industrial Control Panels.”
So, really, what’s the difference?
The difference between NEMA Type and UL Type is that manufacturers can self-certify NEMA Type enclosures, but UL Type enclosure performance is verified by UL through a series of design review and performance testing.
Explore the chart below for guidance on NEMA Type ratings for enclosures used in indoor and outdoor nonhazardous applications.
What to look for when evaluating industrial enclosures
When you’re ready to specify an enclosure, you’ll want to key in on vendors who can provide the following capabilities:
- Third-party certification: This helps verifies a manufacturer's claims are valid and keeps them honest
- Robust construction: Look for fully-welded, steel construction
- Precision: Robotically-applied, continuous foam gaskets
- Configurability: Multiple styles and sizes, covering a wide range of applications
- Customization: On-demand modifications (size, openings, color, accessories and more)
- Personalization: Modified to blend or match surroundings
