Industrial enclosures for computers, printers, and electronics come in a variety of colors, sizes, and materials. When searching for the best fitting enclosure for a specific environment, it is paramount to consider what material the enclosure will be fabricated out of and how it will perform under severe conditions. A buyer or end user should also analyze the enclosure’s NEMA rating because it will determine if the enclosure can withstand harsh circumstances, such as dust, dirt, grease, oil, hose directed fluids and corrosive materials.

3 Strong and Reliable Materials

Carbon/Mild Steel
Heavy-duty mild steel (low carbon steel) is commonly used for NEMA 12 and NEMA 4 computer, printer, and rack mount enclosures. The website, Fractory, describes the versatility of mild steel, “Due to its excellent properties, mild steel has become an in-demand material in various industries. It has unparalleled weldability and machinability, which has led to an exponential increase in its usage…. It is the most common type of metal used around us.” Most mild steel enclosures are produced from hot or cold rolled steel. Mild steel enclosures can be deployed both indoors and outdoors but will not withstand corrosive environments. A powder coated finish will improve the overall durability and longevity of an enclosure constructed out of mild steel.

Stainless Steel
Stainless steel computer, monitor, and printer enclosures are popular for corrosive industrial environments (pharmaceutical, food, and beverage industry). Type 304 stainless steel is the industry standard for NEMA 4X enclosures. However, Type 316 stainless steel may be desirable for its higher grade, which includes 10% nickel. Nickel provides increased corrosion resistance to chlorides and other commonly used harsh chemicals in washdown atmospheres. Super Steel Fabrication, out of Eugene, Oregon, breaks down the real advantage of stainless steel, “Stainless steel is a low carbon steel that must have a minimum of 10% chromium. The addition of chromium to the steel causes the formation of a chromium-oxide film which gives stainless steel its unique properties such as its resistance to corrosion and its ability to heal itself when in the presence of oxygen.” The one downside — stainless steel can cost upwards of 2-3 times as much as mild steel enclosures.

Non-Metallic
A non-metallic material is commonly used in junction boxes or electrical style enclosures. These enclosures are easily modified on job sites and weigh far less than carbon/mild and stainless steel enclosures. Non-metallic enclosures made of fiberglass are commonly used in various sectors of industry. According to Structural Fiberglass, Inc. in Bedford, Pennsylvania, fiberglass has many advantages, including: high impact strength, non-conducive, low maintenance, easy to assemble, corrosion resistant, chemical resistant, and fire resistant. It is often a more cost-effective solution compared to stainless steel enclosures in corrosive environments.

When deciding what enclosure will work best in a specific environment, one other important consideration is weight. Depending on the application, a lightweight enclosure may be preferable when mounting to a pole, ceiling, or wall. For example, an object that weighs around 2 pounds when made of aluminum can weigh 6.5 pounds if fabricated from steel.

The overall material of the enclosure should be one of the first factors to consider when finding a new enclosure solution. There are many design factors that arise when determining the type of enclosure material that is best for a project.

Once the enclosure material is decided upon, everything else should fall into place.

4 important factors to consider for the perfect solution:

1. Environment  

Knowing about the overall installation environment is critical to choosing the right enclosure. If the enclosure will be installed near water, dust, dirt, grease, or any type of contaminants, be familiar with the NEMA (or IP) rating that will provide the appropriate level of protection. Excessive heat is also an area of concern. Internal components need to have ample room to ‘breathe’ inside of an electrical enclosure.

2. Electronics

Make a list of the internal components that will be installed on the inside of the enclosure. Understand the amount of heat (wattage) the electronics will produce, as well as the required minimum and maximum operating temperatures. It is important to know if the selected enclosure will be able to dissipate the heat load. Thermal management should be considered for most environments, as proper airflow is vital to keeping electronics ‘cooled down.’ For a recommendation, ask an enclosure specialist to provide a thermal management worksheet. Based on the data provided, a recommendation can be made for cooling and/or heating the enclosure.

3. Accessibility

Will you need to access different sides of the enclosure to reach components? For instance, will there be enough space to reach a pertinent wire? Consider how cables or conduit will enter/exit the enclosure and be mindful of the maintenance personnel that will service the electrical enclosure. If the electronics are placed too close together, a routine procedure can turn into an arduous task. Always account for the proper amount of internal space – this will provide room for the proper airflow and access for a technician’s hands. Also, be aware of any obstacles that will reside on the sides, front, top, bottom, or back of the electrical enclosure. This information is also helpful in determining the swing or span of the door.

4. Room to Grow

The smallest or least expensive electrical enclosure is not always the best solution. Although space equates to a lower cost, consider the long-term sustainability and reliability of the equipment. Electronics are ever changing. Does the enclosure provide room to grow?  Do not choose a size that provides just enough space to house the current list of electronics. Consider any potential future components that may need to be installed. Remember, if the enclosure is not an adequate size to install a control, the entire system will need to be replaced later. It is never an easy task to change out an enclosure once the components have been installed, so make sure it is correct on the initial installation!

Consider all options for deploying enclosures at your factory or manufacturing facility. Obviously, before installation, weigh all pros and cons. It cannot be stressed enough: homework and research, at the beginning, will greatly decrease the need to replace or repair electronics down the road. Find a solution that will protect and secure your valuable equipment. In turn, purchasing a “cheap” or substandard enclosure can mean downtime and lost money!
