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 is well understood but it is easy to overlook the fact that electro-mechanical devices also generate substantial amounts of heat, especially as they get older.

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 past. That heat needs to be dissipated properly and efficiently in order to maintain a reliable electrical system. When planning your next project, consider these thermal management solutions in your industrial electrical design plans:
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. Continue reading →
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 even when one component stops working.
When an enclosure air conditioner is located outdoors or in an environment that is not temperature controlled, it usually has to work harder in the summer months to maintain the desired internal temperature. Because it will be running more frequently than usual, it will need more regular maintenance to ensure proper operation.
Electrical enclosures are generally designed to allow cooling by natural ventilation, supplemented sometimes by forced ventilation. This usually works well, but there are situations when overheating of electrical panels occurs due to internal heat load, environmental, ventilation, and air flow capacity constraints.
When selecting a temperature control solution for electrical enclosures in applications such as telecommunications, water treatment plants, manufacturing plants, or industrial complexes, several factors must be considered. These factors will determine whether a filtered fan system or closed loop enclosure air conditioner is the best choice for protecting the electrical equipment from damage.
Managing enclosure heat gain needs to be a part of everyday business operations, as failure to do so may cause electrical components to overheat, resulting in equipment downtime and lost productivity. Manufacturers suggest maintaining enclosure temperature of 104°F (40°C) or less is acceptable. Ideally enclosure air temperatures should be maintained closer to 95°F (35°C) since localized temperatures surrounding the electrical components can often be higher. Continue reading →
Electrical cabinet cooling systems are designed to maintain internal electrical enclosure temperatures so as to ensure electrical equipment inside the enclosure remains below maximum design temperatures. Research shows the life expectancy of electrical equipment is halved for every 18 ºF increase in temperature. So, it’s imperative to provide cabinet cooling systems for electrical enclosures subject to high heat loads, especially those enclosures situated in locations where natural cooling is ineffective or exposed to dust and chemical pollution. In order to reduce running costs and to ensure proper cooling, high efficiency cooling systems should be used.
