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.

Although many electrical enclosures are naturally ventilated, there are a number of sound technical reasons for using sealed electrical enclosures. These include keeping components clean, dry, and preventing ingress of corrosive materials and dust. However, modern electrical and electronic equipment generates a significant amount of heat that must be removed from the enclosure, and sealed electrical enclosures cannot rely on traditional ventilation or fans for cooling. Thus, closed loop cooling is needed to ensure internal temperatures are maintained at safe levels. Continue reading →
The widespread adoption of enclosure air conditioners to keep electrical enclosures cool has enhanced enclosure reliability and allowed the use of sensitive equipment in harsh locations. Further, the availability ofonline tools for selecting air conditioners has made it easier for enclosure cooling designers to choose the right air conditioners for their applications. But sometimes solutions are not that obvious and outside help is required. Here are seven enclosure air conditioner questions that, perhaps, you should have asked.
When selecting an enclosure air conditioner, it’s important to make adequate allowance for the effect temperature has on the cooling capacity performance of the unit. As the ambient temperature increases, the BTU/H capacity of an air conditioner decreases. This phenomenon, depending upon the design characteristics of the unit, is affected by the choice of refrigerant, compressor design, and the type of expansion device used. It also depends on the climatic and environmental conditions on site along with any special requirements that may exist.
Air conditioners are typically required when the enclosure’s heat load is over 300 Watts and in extreme ambient temperature conditions.Enclosure air conditioners are capable of working with high solar heat gains, in poorly ventilated areas and even in highly polluted areas. However, there may be constraints that prevent the use of a conventional side-mounted air conditioner. A top-mount air conditioner’s design makes it suitable for various applications. They have been used in applications such as automotive assembly systems, material handling systems and military applications. There are specific scenarios that demand the use of top-mount air conditioners as opposed to side-mounted air conditioners.
Once you’ve purchased the correctly sized enclosure air conditioner, there are a few preliminary steps involved before mounting your new equipment.
The AC unit will be shipped separately from the enclosure, along with its instructional manual. This packet will contain specifics about mounting, transporting and servicing the unit, which will help you maintain its optimal performance and safety.
Before you begin, you’ll need to conduct preliminary testing on the AC unit.
Cabinet air conditioners can have a tremendous impact on the performance, efficiency and overall lifespan of the electrical equipment inside your enclosure. In addition, efficient air conditioning can save energy and decrease utility bills for your electrical equipment. Enclosure cooling is commonly an afterthought in design but integrating the right air conditioner in your enclosure can prove to be an asset for your business. Different factors need to be considered before choosing a cabinet air conditioner for industrial applications. Continue reading →
When designing an electrical enclosure for one of your customers, it is important to ensure that the air conditioner you select is compatible with the system. Multiple factors must be taken into consideration to do this properly. Working closely with both your customer and your enclosure air conditioner supplier is the best way to ensure that the cooling system is properly sized, suitable for the surrounding environment, and fits within the space allotted.
Enclosure air conditioners are necessary to remove the heat produced by your electrical equipment and to keep it running at an optimum temperature range for maximum efficiency and performance. Your decision on a specific model should factor in its operating voltage so that it is compatible with the supply voltage at your facility. Enclosure air conditioners are available for use with all common supply voltages and frequencies.
There are some inherent properties of supply voltages that you need to understand to make a more informed decision about the enclosure air conditioner model that would fit your requirements. Continue reading →
Waste water treatment plants process and purify industrial and domestic waste water so that it is safe to discharge into water courses. As such, these plants must operate reliably at all times as any equipment failure could lead to the discharge of untreated waste into water channels, causing damage to the environment and leading to punitive action.
