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.
Electrical equipment such as VFDs, contactors, and PLCs generate heat through power losses. This same equipment can lose efficiency, operate erratically, or even fail prematurely due to excess temperatures, resulting in reduced productivity, customer dissatisfaction, and lost revenue.
Excess heat can cause electrical components, such as PLCs, VFDs, and power supplies, to lose efficiency and reliability, and may even cause them to fail early. In an industrial setting, these components are housed in protective enclosures, which trap waste heat and raise the temperature of the enclosure air above their maximum allowable temperature.
When you are selecting an enclosure air conditioning supplier, you’ll want to make sure the supplier is capable, competent, and that their equipment meets your requirements. So, before placing an order, spend a little time evaluating potential suppliers to make sure you select one that will deliver the quality you need. Continue reading →
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:
Mechanical and electrical equipment used in water and wastewater treatment systems include a range of pumps, blowers, motors, meters, and sensors for critical operations. Electrical controls for this equipment must be protected from hazards such as corrosive vapors, cleaning fluids, chemical reagents, and contaminated water, as well as environmental dust and dirt, particulates from treatment chemicals, and inclement weather.
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.
Designing an enclosure cooling system for a water treatment plant is different than for most other industrial settings. The environment in and around the plant is far more likely to have high humidity, and to be exposed to the corrosive liquids and vapors from the harsh chemical reagents required to sterilize the infrastructure from viruses, bacteria and other toxins present in the wastewater stream.
Choosing the right enclosure air conditioner involves more than just selecting a unit with adequate capacity. It’s important to consider the energy efficiency of the air conditioner as well as its long term reliability.
For many projects, a buyer will insist on several bids from vendors before placing orders. This is a valid requirement but, unless care is taken when selecting enclosure air conditioners, products selected may not meet operational requirements because the comparison process doesn’t take into account aspects other than the initial price.
