How a Cabinet Cooling Fan Can Cut Project Costs

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:

Conduct Preliminary Testing Before Mounting an Enclosure Air Conditioner

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.

The Importance of Comparing Cooling Capacity Performance when Selecting Enclosure Air Conditioners

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.

Steps to Take When Inspecting a Thermal Edge Unit

Thermal Edge supplies three different types of enclosure cooling equipment:

Filtered fan packages

Air-to-air heat exchangers

Enclosure air conditioners

In order to ensure proper operation, these devices should be inspected periodically. Here are ten simple steps to take to check that your cooling equipment is working correctly. These checks should be carried out by someone who is competent to work inside electrical enclosures. Refer to equipment manuals as necessary, and keep a record of findings for future reference.

6 Enclosure Cooling Considerations for Large Electrical Machines

A large machine includes any machinery that is physically large, complex, and operates as a standalone machine or integrated into a production line. Examples include cement kilns, paper making machines, heavy presses, and manufacturing machinery.

To ensure reliable operation, electrical control equipment must be protected so that the operating environment complies with manufacturers' specifications for temperature and humidity. It's also essential that equipment is kept clean and free of contamination. There are several  cooling options can be used to meet both of these requirements.

How to Avoid Expensive Design Changes with Enclosure Air Conditioners

From time to time, electrical enclosure designers find themselves in a bind because of constraints that limit their options when designing or upgrading enclosures. Typical issues include space limitations, excessive heat load, poor ventilation, dust and dirt, and high ambient temperatures. Solutions that entail the relocation of the electrical enclosure, moving adjacent equipment to create space, or installing a larger enclosure frequently turn out to be expensive, impracticable, or involve significant disruption.

A possible solution is the installation of an enclosure air conditioner. Here are some scenarios where this might be the best alternative.

Selecting a Weatherproof Electrical Enclosure & Cooling System

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.

Why You Need More than Just a Cabinet Cooling Fan for Electrical Drives

It is generally acknowledged that both AC and DC electrical drives operate at very high efficiencies (≥95% for AC and ≥98% for DC). However, even these high efficiencies leave losses manifested as heat dissipation from these drives. Along with the many pros and cons for the two drives, the type of enclosure required is often a major factor in making a final choice. For both AC and DC drives, the heat generated makes it important to carefully consider the sizing of enclosures utilized, as well as how those enclosures are ventilated and/or cooled.

5 Precautions to Take when Enclosure Cooling System Is Subject to Vibration

Electrical enclosure air conditioners installed in locations subject to vibration may fail unless special precautions are taken to prevent failure. These locations may include steel structures supporting heavy equipment, marine environments, and off-road equipment. Fortunately, it's possible to mitigate the effects of vibration on enclosure air conditioners. Here are five steps that we, at Thermal Edge, take to proof our enclosure air conditioners subject to vibration.
