Pure and Pressurization for Electrical Enclosures Defined

Purge and pressurisation in electrical enclosures enables the companies to house an electrical equipment in hazardous or extreme environments. In line with this, before control units will powered up the electrical equipment, there are flushes of hazardous gas and dust. These are usually coming from the motor housing, cabinet, or enclosures and they are flushed with clean air. It is important to note that the electrical equipments housed inside the enclosures does not need for any certifications or approvals. 

Most of the time, companies use compressed air for purging. The rate of flow and the longevity of the process depends on the volume of the enclosures as well as national & international standards should be applied. There are handful of companies that purge with nitrogen air, though one can use any inert gases but nitrogen is the most widely used.

The enclosures for purging and pressurisation usually have doors for efficient equipment maintenance. There are also windows for easy instrument readings. Most of the operations can control the equipment through operating push-buttons and switches located outside the enclosure. It is important to note that all of the components installed on the external of the enclosure are possibly surrounded by hazardous dust and other gases. The said components should be classified, certified, and approved to be safe.

The techniques used in pressurizing and purging electrical enclosures used to house electrical apparatus are designed to keep ingress of flammable atmosphere from happening. By definition, purging is a widely-accepted concept process for protection from explosion. Purging is accepted world-wide in terms of European standards, NFPA, or IEC. It is straightforward and easy to adopt and comprehend. Protection from explosion is achieved by keeping any possible source of ignition – such as thermal or electrical – from atmosphere that may contain any explosive gases. The apparatus that has a possible ignition is installed inside the enclosure. Then, the enclosure is now pressurised to a positive pressure equivalent to atmospheric pressure. Usually, a measure of 0.5mbar is all that is required.

If the positive atmospheric pressure is maintained inside the enclosure, no gas nor any dust will be able to enter or ingress the enclosure. It is safe to say that through this process, the equipment inside the enclosure will not have any exposure to potentially explosive gas that may be present in the environment. However, it is important to note that there is a possible gas mixture that have entered the electrical enclosure before the positive pressure is applied. To make sure that this is prevented from happening, a flushing out of the existing content in the enclosure is required (such as air, or nitrogen). This process is also meant to make sure that all the area inside the enclosure only contains the purging gas. This process usually takes 5 and 10 volume changes before the purging is finally considered done. However in Europe, the minimum purge standard is set to five air changes while in North America it is set as 10 air changes. The purging of internal dusts still has not been considered to be possible.

Different Types of Custom Metal Enclosures for Electrical Equipments

Any company who needs custom electrical enclosures for their equipments can be provided by any enclosure manufacturing company. They just have to be specific with the design that they want to achieve. This also includes the type of steel material they would like to have, such as – aluminum, stainless and carbon steel. Lead times may also vary so a good communication about what is needed to be achieved is important.

Also, there is an option for an enclosure to be customised – via silkscreen or engraving. In addition to this, a clear understanding of the NEMA or IP rating needed for the specific enclosure will be helpful in communicating to a certain manufacturing company of the enclosures needed to be designed.

There are several type of customisation a company can choose from: wall mount, free-standing, floor mount, JIC and through. It is important to note that the size for these enclosures are not limited, they can be built according to the needed size for the electrical equipment. One of the most common one is the free-standing portable enclosures.

In regards to the parts of the electrical enclosure, a company can request for an adjustable swing door assembly. This provides an extra space for the inside and the outside for the enclosure for the specific electrical equipment. This will allow the company to easily assemble the electrical equipment inside the enclosure. Doors can made of solid metal, a feature window, and cutouts or mounting holes. Different applications call for different customisation needs. There are also clamps, latches, turn handles, and lock options if you would like an added security for your electrical enclosure. For other seal options, there are strips, die-cut, and bulb extrusion. This enables the enclosure to protect your electrical equipment inside. Communication is the key, let your manufacturer know of what other types of features that you would need.

The other feature that you can add is pem studs and nuts. It can be placed on the back panel of the enclosure of wherever you need them for an efficient installation. There will be no need to drill or tap mounting holes and this will also save your company resources and time. Additionally, there can also be gland plates that can be placed through custom cuts and holes. This can be placed on either side or top/bottom part part of the electrical enclosure.

Different customisation for different applications are needed. Some of the companies manufacture electrical enclosure for different industries, such as: fire protection, food and beverage, water treatment, power generation, communication/telecom companies, transportation, chemical, wastewater management, petrochemical, and oil and gas. One should note however that there are companies that only specialises for specific types of industries. Message the manufacturing companies to know more.

Lastly, do not forget to be specific about the different protection you need for your electrical enclosures. Most of the common protection enclosures can have are: corrosion-resistant, water and dust ingress, hose-water resistance. There are also submersible enclosures for marine offshore companies.

What are Different Accessories Being Used for Server Racks?

Cage Nuts

Cage nuts are primarily being utilized for the server racks that comes with square mounting holes. This very useful hardware will give you the provision to quickly change the threads interchangeably while never having some of the stripped tapped holes being seen on the server rack. The cage nuts can come in variety of multiple sizes, but there are three most common types being used today. These are the 10-32 Cage nuts, 12-24 Cage nuts, and as an M6 Cage nut.

The type of cage nut will greatly depend on the type of equipment you are mounting; one would easily choose the specific type of cage nut in order for them to match the equipment they are using. The only disadvantage to some of the cage nuts is that it can be really difficult when they install or remove them. However, the cage nut removal tool removes this problem.

Filler Panel and Blanking Panel

These two have different names but they almost have the same meaning. Let me explain the major differences between the two, the filler panels or the flat sheets of metal has that “fill” empty “U” spaces located on the server rack. The important thing about these panels are they are effective in assisting the airflow very efficiently and they are managing the prevention of exhaust air being released from warming the cooler air. This entire process contributes in helping of cooling the server rack more efficiently. The filler and also the blanking panels became one of the best yet cost effective methods of decreasing the energy costs.

“U” Space/Rack Unit

The single rack unit or “U” space is almost equivalent to 1.750 inches or 44.45 millimeters worth of space. This one “U” worth of space has the inclusion of three holes that comes with the mounting of the hardware unto the server rack or wall mount. When you are deciding on which server size that you would greatly need, most of the engineers will probably consider the number of “U” spaces initially before doing a research on which type of server rack they should purchase.

What is the Main Difference Between Server Cabinet and a Network Cabinet?

The server cabinet, which is also commonly called as an enclosed server rack, has a removable rear and front doors. The side panels and the adjustable vertical mounting rails are also included. The rack server cabinet that is being used in standard data center has a height of of 42U or 73.5 inches high. For the majority of server racks, these cabinets consist of 24 inches in width and they are 36 inches deep. Recently, the server cabinets have been popular across companies that has data centers and also server rooms.

A network cabinet is generally being used for several routers, switches, fiber patch panels as well as equipment being used for networking. For the majority of cases, the network cabinet is shallower compared to its server cabinet. They are generally less than 31 inches when it comes to deep measurement. There are times that it consists of a glass or it has a strong plastic front door. There is more to this also. The network cabinet commonly does not have perforated enclosures.

These type of cabinets are more popular because of the following primary reasons:

  1. Added security – compared to the insecure rack, the server rack cabinet gives added protection. The cabinets can be easily locked to avoid other visitors or unauthorized people to gain access to the equipment.
  2. Protection for Cables – together with the door and other side panels, the cables inside the server rack cabinet has much more less access compared to the outside air. This now helps in preservation of the cables in order to decrease the risk of cable damage because of some contaminants.
  3. Better filtration of air – the server cabinets can also be utilized by engineers to be able to provide a wide variety of air segregation or filtration strategies. For example, this can be used when there is a cold or hot aisle containment and cabinet-level type of containment.

With this in mind, there also comes some great disadvantages:

  1. High Price – unlike to the server rack, this cabinet is greatly more expensive.
  2. Cannot be accessed easily – because of some physical restrictions for this cabinet, it usually takes more time to do a manual operation or even do system maintenance of the equipment being housed inside the cabinet.

When a design engineer is building a data center, in deciding what type of server rack or cabinet to be used – and even network rack & cabinet – to use should be the top priority. The right one should be able to meet some of the installation demands and it can help you to greatly improve the power protection needed, including the cooling, cable management, and also the physical security.

What is the Best Rack Design that can Work Best for Your Engineering Project?

The majority of the server rack enclosure manufacturers will allow you to be able to select across several options, so that the server rack for your engineering project can meet the specific requirements where it will be installed (depending on the environment.) There are common areas where the engineer should be able to select options from.

  1. Shelving: the majority of the manufacturers can offer numerous options for your server rack shelves. This include some of adjustable or fixed server shelves that comes with four-point mounting. It also includes some keyboard shelves that has 2-point mounting. It is slightly vented, very durable, and has cantilever shelves. They also have media shelves. The project engineer should be able to effectively choose a server rack wit the depth of 6 inches that is lesser than the overall depth of the server rack. Once you have a server rack that is 30-inch deep cabinet, you should be able to effectively choose a shelf with a depth of 24 inches.
  2. Top and Side Panels: these panels are designed to give equipment protection from the foreign materials. The feature options that are included are the perforated slots for added ventilation, grommet holes designed to accommodate the supplementary cable management pathways, and there is also an option to mount the exhaust fans. The existing side panels gives security and they are most often available in wide variety of choices: solid fixed, solid removable, and solid that has vents included.
  3. Mounting rails: these are the most commonly used racks that comes with two different sets of mounting rails. In addition to this, the additional rail sets can be bought in order for it to accommodate the different depths in order to start rack loading. The majority of the manufacturers will allow the usage of these from either Universal Mounting Rails or EIA standard rails.
  4. Universal rails: they will be able to support the 19” EIA width rackmount including the networking equipment, and almost all of the server equipment. The EIA standard mounting rails will be able to support the 19” EIA width rackmount and also the additional networking equipment to be able to support the other manufacturers’ rack mounting equipment.

In addition to tis, whether the rails consist of square or tapped holes, the majority of the mounting rails should be able to comply with the ANSI/EIA-310-D standard (1992). The majority of the manufacturers of server rack recommends to purchase racks with rails that has square holes and cage nuts. Today, most of the off-the-shelf rack models are being used for rails that has square holes.

Do You Know that Having an Improved Graphics Department Would Mean Arriving at Better Choices for Your Company?

There are companies that does not mind improving their graphics department. It is akin to a car without a gas. However, there are companies that chose to be always better when it comes to this certain department. I helped them come with a better final product because of the skill set the graphics department will bring to the company. What’s more interesting is that the details the company wants to have for their enclosure can be greatly illustrated by a well-taken cared of graphics department.

Like this example. When it comes to designing enclosures, the process cannot be as simple as just adding more ink to the printing of text on the enclosure. There are specific equipment that needs to have the assurance that a second hit is already applied on the right location on the enclosure. Just a millimeter half off and the text will already have a very shadowy effect. This actually beats the purpose and it will now have a shadowy effect or appearance.

With this in mind, companies require the extensive training of some of their design engineers and their printing technicians to make sure that the precision of printing and design is achieved whenever there is an engineering project. Throughout each and every piece of product being manufactured, the precision should always be assured. Regardless if the production runs on one piece or even thousands of units.

There are specific pieces of some of the electronics equipment that are initially required to properly invest on part of the company. The expenditure of additional equipment should be a no-brainer for the companies that produces quality enclosure. The improvement of their production equipment would mean that they will get a higher right precision and they can get consistent high results during every production of the product. They can also make sure that they can reduce variables that can account for some of the printing errors they can encounter.

For example, there is a specially designed printing lab designed to maintain different atmospheric variables such as humidity and temperature. Also including the dust saturation that can put the production of the enclosures at great risk. Also, it should be noted that in making sure that top quality is prioritized, the equipment that are being used and the processes should maintain a perfect balance.

Companies choose to make this kind of difference to their graphics department to make sure that they only deliver the best product and services to their customers. But not risking the customers’ satisfaction. These companies are confident with their prices together with the right level of precision and                   quality while offering the best prices in the market.

How to Determine and Pinpoint the Exact Dimensions for Plastic Electronics Enclosures?

We recently just moved and re-arranged the furniture in our living room. My dog’s own crate has always been placed in the corner of our living room. Along wit some of our new furniture, there was no longer a room available for my dog’s crate. So we have to identify or look for another space for the crate. Since my dog is a medium sized Labrador, the crate is super huge.

To be able to move this into a new space or location, we have to run our creativity. We have to find a space spacious enough to fit the crate so that it can crate up and be installed on the wall. This in return, reminded me of the video game, Tetries.

I was being reminded of this fact while I was talking with a customer just the other day. The customers often call to our company because they want to ask for help in selecting the right enclosure. This person was particularly looking for a “a CD ROM sized enclosure”. When I told the customer that I would be more than happy to find something similar to that size range, the customer told me that it is just what he exactly needs as per dimension wise.

The customer then was really hoping to produce a product that would be able to slide into the same area like the optional CD ROM available in the computer. In order to fit that exact space, the customer need the right dimensions. This is too large and it would not eventually fit, and too small that it will not hold very stable.

As we have recently discovered, this problem presents several difficulties on a very few levels. While the majority of the manufacturing companies will shape the enclosures with several type of ranges to be able to offer the best choice available to the customers. However, it is nearly impossible to be able to find the exact match for the dimensions within a different product line.

There are companies that offers wide range of sizes and different styles of electronic enclosures. Several of their enclosures are mostly rectangular in shape, but majority of them have the same ratio of length that ranges form width to height. We just recently found out that the most used size range is 2 x 3 inches, and in line with this there are several options that exists within the 1/2” range. While each of them consist of a very deffierent depth.

This is to be able to give you the best and with the most options possible to help in finding out the most perfect enclosure for the companies’ needs.

How to Stack the PCB in Some of the Plastic Electronic Enclosures?

Do you know where the cabinet in your kitchen place where the food containers are usually kept? You need to have these spaces for the food leftovers but with all the different sizes, depths, colors and it can lead to the chaotic space in the kitchen. And the kitchen space has all the covers for these spaces. What you should do with them?

With this in mind, I have finally discussed about my own kitchen and I have finally cleaned up my kitchen area. I have found out that if I will be able to stack all of the plastic enclosures together – together with the slide covers being neatly placed next to the bowls – then, it will be no longer a chaotic mess. Now, I can finally breath when I once open the door.

I finally got the idea on how to stack these different containers from a recent customer email sent to an enclosure company. The customer has liked the size of one of their enclosure, but the engineering project he has been working on required 2 PCBs. These 2 boards were being utilized to control different engineering operations. The final question is: will he be able to stack the 2 boards within the DC-45 without causing any issues?

The company told the customer that this will not present any pressing issues. Providing that he is currently using spacers between these two boards that can allow the air between the boards. There would be plenty of room to stack the boards of them. The spacers would function as the support to be able to mount the PCBs together.

Because this enclosure that the customer requests set only one mounting bosses on the base, and none in the cover. The customers have to use an additional method to secure the second board. There should not be any bosses for the top of the board that can be mounted to.

In using the spacers, the project engineer would not need the bosses available for the second board. The spacers will also allow for air movement around the boards in order to prevent the overheating of the two PCB boards.

An additional way for this to happen is to have a machine countersunk in the holes in the cover and be able to use the separate stand-offs to properly secure the board. This specific method is a similar way that we can use to move the location of the position of the mounting bosses for the customers.
