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 is the Latest News About the Green Movement?

I am fully aware as an individual of the responsibility I have in taking care of the environment. This means that I should shift and maintain my lifestyle that supports the environment. This entails choosing the right products to use and supporting organic farming. However, this is easier said than done. There are a lot of things that are needed to be done end because of it, this process should be taken in a step by step matter.

Also I try to incorporate this in my everyday lifestyle. This means that I am doing my best to recycle all the plastics from the packaging of the products, etc. I should always turn off the water when I am brushing my teeth. I remembered the thought of “every little piece” counts when it comes to doing the 3R’s of cleaning the garbage.

In light with today’s industrial companies – also including the individuals – we should be all vigilant in doing the country’s effort in the conservation and the protection of our environmental resources. They are not there forever and we should be taking care of them for the next generation. In terms of upgrading to a very good efficient lighting installed in our offices and warehouses, is the best way to reduce the energy consumption of the company while contributing to the efficient energy plan of the country. This is while we do the improvement for the work environment.

There are companies now that has started the retrofitting of their lighting installed in their offices and warehouses. This retrofit process carefully replaces the majority of the components within a lighting system that has equipment counterparts to be able to utilize energy more efficiently.

With this in mind, according to statistical data from the Energy Information Administration, the majority of the electricity being used in the Untied States comes from the consumption of businesses to operate the buildings. Because of this huge consumption of electricity in United States, it is estimated that this process has caused the increase in CO2 emissions up by 38%.

The companies now should start thinking and developing ways how they can promote the efficient usage of electricity because this will have a great impact on the environment. Companies should start devising ways how they can reduce their carbon footprint. Ligting Retrofits will effectively calculate how much of the electricity will be saved and the amount of emission reduction that will happen from the lighting upgrade.


Do you Need Large Enclosures for Huge Engineering Electronics Projects?

Whoever said that big things are always the better things, this saying is obviously will not work when it comes to electronic enclosures industry. Companies believe that good things can come in really big packages – especially on electronics enclosure. The largest size of electronics enclosures shows that there is enough interior space that comes with a very strong and durable exterior that is just perfect for catering your heavy-duty project requirements.

With this in mind, let us start with a company’s electronics enclosure product that is readily available with or without the surface mounting flanges. The electronics enclosure box comes with the 10 x 6 x 3 inches and is readily available in colors black or gray. The optional smooth area that comes with it is very ideal when displaying some of the graphic overlays. The enclosure can come with its standard 8 PCB mounting bosses that is found on the base. The covers of its screws also has the brass inserts for a smoother and more efficient use.

There are also some sizes that is just perfect requirement for some for of weather proofing of enclosures. Some of this also belongs to the companies’ NEMA-rated enclosures family. For guidelines, here are the dimensions you and a company can use.

  • 10.43 x 7.28 x 3.74 inches
  • 10.43 x 7.28 x 3.74 inches
  • 9.45 x 6.30 x 3.60 inches
  • 11.81 x 9.05” x 3.40 inches
  • 14.12 x 7.84 x 5.96 inches

These specifications come with specific sizes that comes in IP ratings IP65 of IEC 529. They also come with some electronics enclosure standard that has both brass-threaded PCB mounting bosses and some shorter plastic bosses. They can also come with stainless steel crews that is being threaded inside the brass inserts to efficiently cover on/cover off some of the applications.

This electronics enclosure assembly also includes some of base, silicone gasket, cover, and 6 enclosures’ screws. There are electronics enclosure that is being molded using a dark gray ABS plastic whilst there are electronics enclosure series that are currently being molded just by using a UV stabilized light gray polycarbonate. This makes them a very good choice for some of the outdoor applications of the customers.


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.


Managing Harsh Elements from Extreme Environments by Utilizing the Proper NEMA Cabinet

If you ever think that you are the toughest man, well think again! If you utilize server racks, they might be even tougher. However, not in the best way. A harshful environment can potentially bring severe damage in your server racks and other technological equipment if they are not being protected efficiently and properly. Extreme environments could potentially include some areas that has falling dirt, outdoor areas, dusty areas, as well as unfinished construction of warehouses.

In able to properly withstand these unideal environemtns to give efficient protection for your equipment, you probably need a NEMA rated server rack cabinet. These NEMA cabinets are initially designed to prvent dust, airborne particles, as well as dirt and other possible contaminants from totally damaging your valuable equipment. With this in mind, consider utilization of the following NEMA rated enclosures for harsh environments for each.

NEMA 12 Electronics Enclosure for Protection from Dust and Airborne Contaminants

These enclosure cabinets are originally made from steel and they are the most commonly used enclosure in environments like production facilities, factory floors, manufacturing fields, unfinished construction of warehouses, and many more. You can use NEMA 12 electronics enclosure in places where there are more dust particles floating around the air more than usual. These server cabinets have a gasketing system on all of its sides and doors and it leaves no room for contaminants to get inside of the enclosure. The normal cabinets also have existing vent patterns around the doors and its sides. While the NEMA 12 enclosures does not have these.

NEMA 3R Electronics Enclosure for Protection from Harmful Elements found in Outdoor Environments

These electronics enclosure can be utilized in both indoors and outdoors, but they are most commonly used for outdoor applications. The NEMA 3R cabinets can give protection for your equipment from solid object ingress brought by dust, dirt, and other particles floating in the air. NEMA 3R is similar to NEMA 12 in most of ways but NEMA 3R was also designed to give protection from other harmful environmental elements such as rain, ice, snow, and sleet.

These enclosure cabinets are primarily built using aluminum and they are mostly used for telecome applications. These applications involve the utilization of Wi-Fi, wireless/broadhband sites, fiber optics, and some trailer applications. The installati of fans or aircondiitoning units are beneficial for this type of enclosure. Especially if your equipment creates a certain amount of heat. The heaters are also widely available when the cabinet is going to be utilized in a very cold environment. The cold temperature can exceed the cold threshold which in return will be very damaging to the equipment as equivalent to too much heat exposure. The NEMA 3R enclosure can be wall mounted, pole-mounted or even pad-mounted (or freestanding.)

NEMA 4 or 4X for Protection from Possible Corrosion Formation or Hose Directed Water

The NEMA 4 and 4X are very in a large variety of ways. Both of these enclosures effectively address the major concerns of a NEMA 12 enclosure as well as the 3R enclosure. These enclosures can also give protection for your equipment against hose directed water. The NEMA 4X can also give you a specific protection from possible corrosion because it is entirely made from stainless steel. The NEMA 4 and 4X are going to be utilized for the same applications where the NEMA 3R is also used. NEMA 4 and 4X are very popular when they are used for traffic enclosures.


What are Automatic Temperature Controllers? The Product Spotlight!

Just last year, my beloved dad gave me an electric smoker. Being a BBQ fanatic his gift is a very wonderful thing to me. It really worked great during my BBQ parties! I was able to cook ribs, pork tenderloin, sausage-stuffed hot peppers. Including some pork brisket! And unlike going to our local restaurant, I already have plenty of leftovers to enjoy for days. Now, you can too!

The Digital Power & Motion was able to create an automated temperature controller for the charcoal fired barbecue cookers just by using one of our plastic electronics enclosures.
