Type 4X Shallow Electrical Enclosure Cooled Economically

By Bruce K Kreeley
Director of Sales , Engineering & Quality Assurance at Kooltronic, Inc.
A major food processing plant came to us with a cooling requirement for a wash-down application on a very shallow stainless steel electrical enclosure housing multiple small horsepower drives. The drives needed to be kept below 104F (40C) for reliable operation. Rigorous cleaning and disinfection of the electrical enclosure exterior via power wash-down is required on a routine basis. They were expecting to utilize an enclosure air conditioner for this purpose, but their enclosure was only 8 inches deep precluding the use of most air conditioners.

Our recommendation was to circulate the room air from the facility through the enclosure using Kooltronic NEMA Type 4X Stainless Steel Filter Fan(s) and Filter Grilles. http://hubs.ly/H05V1pl0 The filter fans and grilles would be placed on the door, the filter fans located near the top of the door. The filter grille would be located lower on the door. The cool room air flows over the heat producing drives, the waste heat discharged near the top of the enclosure.

This economical approach allows a shallow enclosure to be used minimizing the complexity of the cooling solution. One last energy saving tip is to add a thermostat to cycle the fans off when the enclosure temperature is cool enough.

The Sources of Heat in your Electrical Enclosure
By Larry Quirk - Regional Sales Manager -
Consider contributing sources that will adversely affect equipment. Whether you have a panel, enclosure or kiosk, the primary source of heat production is from the working components. For example, nearly all of the power used in electric devices is converted into heat This internal heat load is one source that will cause the enclosure temperature to rise to an unacceptable level. To help estimate heat generation, a good sizing program will assist you.

What are your biggest concerns of heat in your enclosure and how do you address their negative effects?

How can you best remove the heat from your enclosure?

By Ralph Hale, Regional Sales Manager

There are several ways to successfully manage unwanted heat. However, let’s first identify the sources. This heat can be a result of working components inside and equipment outside the enclosure; hot ambient air and solar gain. So, based on the conditions, a fan, blower, heat exchanger or air conditioner may be required. A sizing program can help guide you in selecting the best option for your application. If you plan ahead and consider all the factors that may have a negative effect on your equipment, costly field retrofits and downtime can be avoided.
