Heat Exchanger, Fan or Air Conditioner: Which Enclosure Cooling Method Is Best for Your Application?

When deciding which cooling method to use for your electrical enclosure, there are a few options to consider. Among air conditioners, filtered fans, and heat exchangers, there are intrinsic differences which can keep your equipment cool and operating properly if the right cooling method is chosen. If not, the electrical components can be exposed to elevated temperatures or adverse conditions, or the cooling system will be inefficient during cooling operations.

Cooling Options for a Sealed Electrical Enclosure

Although industrial electronic components are generally robust and well designed, they are sensitive to contamination, moisture, and excessive temperature. They need to be kept cool, dry, and free of dust, debris, and corrosive chemicals. These requirements are to a certain extent in conflict because good ventilation is generally required for cooling, but protection from dirt and contamination requires a sealed enclosure.

Differences Between UL & cUL Requirements for Electrical Enclosure Cooling Systems

UL stands for Underwriters Laboratories in the United States, and the initials UL represent their mark of approval. UL has laboratories in several other countries, and in Canada their mark of approval is cUL.

Underwriters Laboratories belongs to a group of nationally recognized testing laboratories; organizations that are accepted by authorities having jurisdiction (AHJs) in terms of the US National Electrical Code to certify equipment as meeting certain specifications. In simple terms, the UL label in the USA and cUL label in Canada on electrical products indicate that the products have been designed, built, and tested to be in accordance with safety standards for those respective countries by Underwriter Laboratories.

Air Conditioner Options to Consider for Telecom Electrical Enclosures

Keeping your electrical enclosures cool is absolutely essential in the telecom industry. Heat is produced not just from the electrical equipment inside the enclosure, but also develops from solar radiation. A reliable and efficient air conditioner to keep your outdoor electrical enclosures at ideal operating temperatures does not have to be unbearably expensive or difficult to maintain.
