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 the equipment in proper operating conditions. Continue reading →
To the outsider, the food and beverage industry operates in a benign and clean environment. Although this assumption is largely true, it requires that facilities are rigorously cleaned and high standards of hygiene maintained. Cleaning processes include the use of chemical disinfectants and washdowns to prevent pathogens accumulating on any surface. Since the introduction of the Food Safety Management Act, the FDA Code of Federal Regulations Title 21, Part 110 was updated and requires that equipment in manufacturing and food handling areas is constructed so it can be kept in a clean condition, even if it doesn’t come into direct contact with food.
Almost everyone involved in the maintenance of electrical enclosures has, at one time or another, faced problems with overheated electrical enclosures. In most instances, the obvious solution was to install or upgrade the cabinet cooling fan only to find that it didn’t work too well.
Cabinet cooling systems are carefully designed and manufactured using high quality components offering maximum life expectancies. In order to ensure continuous trouble free operation, the system should be periodically maintained making certain the cooling system is working properly.
When you purchase an electrical enclosure to house your equipment and keep it safe, you’re investing in the longevity of all of the electrical components. Electrical equipment can produce substantial heat, so also adding a cabinet cooling system to the purchase can keep your unplanned maintenance needs to a bare minimum. Having the proper operating temperature reduces overall system fatigue and keeps your equipment at peak condition. Continue reading →
Provided the conditions are right, the lowest cost method of cooling an enclosure is to use filtered fans. The reasons are simple: fans are cheap, cost very little to run, and are capable of moving a significant amount of air. Furthermore, there is not a lot that can go wrong with them. The basic requirements for the successful use of fans include: Continue reading →
The most common reason for reduced efficiency, malfunctioning and failure of electrical equipment is
high temperature. Electrical equipment such as variable speed drives and PLCs are designed to work within a particular temperature range. It is reported by Schneider that a 10°C increase in temperature could halve the life of the equipment. Therefore, it is imperative that the enclosure that houses the electrical equipment be designed with thermal management solutions in mind. A small investment in temperature control solutions could result in increased uptime and lower maintenance issues, improved efficiency of equipment and an increase in overall productivity for your business.

Reliable operation of electrical equipment in an enclosure is dependent on its operating temperature. This in turn depends on the heat load of the electrical equipment and method of cooling adopted. In many instances, natural or fan-assisted ventilation is used. This is only viable if three conditions simultaneously exist. These are:
Low heat load
A moderate ambient temperature
If any of these requirements can’t be met, enclosure cooling that relies on using ambient air won’t work and enclosure air conditioning is required. Continue reading →
Although cabinet cooling systems are robust and reliable, their efficacy depends upon their correct design, selection and installation. It is essential that cooling solutions are properly sized to the heat load and environmental considerations are taken into account. Unfortunately, this is not always the case, especially when equipment is replaced or upgraded by personnel with limited enclosure cooling expertise. Here are seven common mistakes that we come across.
