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 of public and employee safety. Continue reading →
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, the chief enemy is not a hacker or the weather, it is heat. Without question, installing the right enclosure air conditioners will add years to the lives of your systems and increase reliability. Enclosures are made to protect and secure the components they house, but without proper cooling, the lifespans of those components will be limited and security won’t mean much.
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 →
Condensation forms naturally when the internal temperature inside an electrical enclosure reaches the dew point and which, if not dealt with, may cause many problems. These issues include the possibility of corrosion, equipment damage, and the risk of electric shock. Also, in electrical enclosures fitted with enclosure air conditioners, water collects on the evaporator coils and has to be removed. Continue reading →
The selection of a weatherproof electrical enclosure needs to be made with care because the definition of weatherproof under article 100 of the National Electrical Code requires that exposure to weather must not affect the operation of the enclosure. Such a definition requires further interpretation when considering enclosures and cooling systems to be installed in locations exposed to harsh weather. There are significant differences in weather conditions between coastal marine locations, wet tropical environments, deserts, and cold climates.
Temperature control is a crucial element in the design of enclosures for electrical equipment. Since manufacturers design electrical equipment to work within a specific temperature range, the heat they dissipate during normal operation has to be removed to avoid damaging equipment. High temperature directly affects the reliability and life of electrical equipment. Manufacturers claim that a 10 °C increase of temperature above the maximum allowable temperature cuts device lifespan in half. The consequences are increased downtime, frequent maintenance cycles and a high expenditure. These are some commonly used temperature control solutions employed in the industry: Continue reading →
“Ambient temperature” is a term you will hear often when researching electrical enclosure cooling systems. But what exactly does it mean? In simple terms, it’s the temperature of the air surrounding an electrical enclosure. As a concept it’s relatively simple, but determining the ambient temperature is not always as easy as it first appears.
The selection of the right size enclosure air conditioner should be based on a careful assessment of the total heat load, ambient temperature variation, and the required enclosure temperature. If the air conditioner is larger than required, energy usage will increase and the unit will cycle excessively. Conversely, an air conditioner that’s too small will run continuously and not control the temperature properly. A number of factors need to be considered when choosing an air conditioner. Here is how to select an enclosure air conditioner with the right cooling capacity:
The temperature of equipment in electrical enclosures must be controlled to avoid the risk of equipment failure due to overheating. In most cases, some form of enclosure temperature control is needed.
These seven tips can help you assess your temperature control systems. Although enclosures dissipate heat, the total heat load in many instances exceeds the rate at which this heat can be dissipated, and the internal enclosure temperature may exceed the maximum temperature limits of the equipment.
