When an enclosure air conditioner on one of your electrical enclosures fails, you need to act quickly before the panel overheats. But what do you do when you cannot find or contact the original enclosure air conditioner supplier or, if you can, they are unable to supply a replacement quickly? What if the technology […]
No one needs to be told how much time, effort and of course money accompanies the systems needed to keep a business running smoothly. Ensuring that pricey electrical equipment, servers and security systems that drive production remain operational is no longer a secondary task. It is a critical business function, and even a matter […]
Although electrical enclosure fans are simple devices, there are safety risks that should be considered during their installation and use. Here, the most significant risks are highlighted and split into three sections: Installation Operation Maintenance When dealing with electrical enclosure fans, safe practices are critical to ensure the safety of personnel and to make […]
In industrial facilities, electronic equipment is frequently used for motor control and most machines are PLC controlled. This use of electronic equipment has increased electrical enclosure heat loads because of the high heat dissipation characteristics of electronic equipment. At the same time, electronic equipment is susceptible to malfunction if allowed to get too hot, […]
There are a variety of plant conditions that can warrant the use of enclosure air conditioners to keep your electrical equipment running well. When an air conditioner is used in conjunction with a properly sealed electrical enclosure, the closed loop cooling system can mitigate many issues.
Thyristors and other solid state devices in variable frequency drives generate a significant amount of heat. These devices are mounted on heat sinks and use a chimney effect to draw cooler air from the bottom of the enclosure and discharge the hot air from the top. The amount of heat is directly related to […]
When working with expensive electrical components in areas with extreme temperatures, having electrical enclosures that will protect your equipment from dust and dirt is important, but even more important is having cooling systems in place to keep the equipment at the proper temperature. High ambient temperatures can wreak havoc on electrical equipment that is […]
It’s important that your electrical cabinet cooling system complies with relevant safety standards. Units purchased for use in the USA should comply with UL and NFPA standards and those for other regions and countries with appropriate national standards. Additionally, US employers are required to comply with the General Duty Clause of the OSHA Act […]
Years ago the use of electrical components made a move from “handy gadget” to “critical equipment.” Computer servers, hard drives, displays and controls all serve as the nerve center to many industries like telecommunications, transportation, manufacturing and elevator controls, just to name a few. And while many forces can wreak havoc on these systems, […]
Enclosure air conditioners for use in the U.S. or Canada are required to meet certain safety standards. Although legal requirements governing the use of electrical equipment appear complex, certain compliance requirements are clear and universally applicable for electrical enclosure cooling equipment. The following seven compliance tips will help you ensure that your enclosure cooling […]
If you want to extend the life of expensive electrical equipment and keep it running efficiently for years to come, you need to consider thermal management solutions that are reliable. As you know, thermal management is becoming more and more critical as many components and control panels have higher heat loads than in the […]
High power components can be divided into two groups, those that are electro-mechanical and those that are electronic. These devices are expected to handle a significant amount of power and generate a lot of heat. Typical applications where components generate high temperatures include motion control and downhole drilling. The heat generation of electronic components […]
Your electrical equipment needs to be sheltered from harsh environments and extreme conditions. Electrical enclosures do a great job of keeping the electronics shielded from contaminants, such as dirt or moisture. But what about the heat produced by the equipment themselves? Choosing the right cabinet cooling system will help decrease unplanned maintenance by keeping […]
When Is the Ambient Temperature Too Hot to Rely on Air to Air Heat Exchangers for Enclosure Cooling?
When you are looking for an efficient method for enclosure cooling, a heat exchanger is a good solution for a few different reasons. Not only is a heat exchanger energy efficient, but it allows you to maintain a completely closed loop enclosure cooling solution. The way a heat exchanger operates is by employing a […]
When you require enclosure cooling for your sensitive electronic equipment, dealing with the outdoor elements can complicate things slightly. Without the constant ambient environment present as in most indoor facilities or the shelter provided by the building to shield the enclosure from precipitation and other outdoor elements, the enclosure can be subjected to much more […]
The use of electrical equipment has revolutionized the electrical industry by reducing costs and making sophisticated electrical control systems practical. Examples include variable frequency drives, PLCs, and electrically controlled circuit breakers.
If you are a project or maintenance engineer needing to purchase enclosure cooling systems, it is important that you spend time preparing a detailed specification before initiating an inquiry. This relatively simple task will ensure you get a cooling system that will meet your needs with appropriate approvals. Here are some tips for writing […]
The pervasive use of electronics in control systems requires not only technical maintenance of functionality and software, but it raises the priority of temperature control inside electrical enclosures to the top of your to-do list.
Understanding the NEC Hazardous Location Option: Class 1, Div 2, Groups A, B, C, and D, for Enclosure Cooling Systems
Electrical control panels, working in busy industrial applications, serve as the nerve center for many businesses. They are a critical piece of equipment that can ring up some expensive downtime if they are not monitored, maintained and cooled properly. Most of the enclosures that house electrical control panels find themselves in hot and dusty areas, […]
Depending on who you might speak with, more than 100,000 new materials have been developed over the last 50 years. If the task facing you involves material selection for electrical components working in an industrial application, that job could be complicated to say the least.
Electrical components in an environment containing chemical vapors and dusts are subject to corrosion, and as a result equipment malfunction or failure is more prone to happen. Even gold and silver plated connectors and contacts are affected as porosity allows contaminants, especially in high relative humidity conditions, to attack the underlying metals.
The market for custom cabinet or enclosure air conditioners is growing as applications become more unique, such as pole mounted heavily loaded electrical cabinets, mobile equipment, and electrical control panels in dusty areas with intense solar radiation.
Unlike a residential cooling system, an enclosure air conditioner must accommodate special situations. The sometimes harsh environments where electrical enclosures are located make it necessary to ensure that the air conditioner protects the components inside beyond just cooling the cabinet. Some examples include:
Enclosure cooling systems are used for a broad range of applications in many types of industries. While every use of an enclosure air conditioner is important, some require unfailing reliability. When this is the case, certain solutions are used to ensure constant operation, including back-up power supplies and other redundant systems that prevent failure […]
