Cooling Electrical Enclosures Without Condensation

Cooling Electrical Enclosures Without Condensation

April 22, 2025


Keeping electrical cabinets cool prevents waste heat from damaging the electrical equipment. Traditionally, this has been achieved with various methods, the most common of which were air conditioning and compressed air-cooling units. However, with today’s high-powered and high-performance technology, such solutions require massive energy consumption and, in some cases, can create additional problems, such as condensation, that can damage the equipment. Fortunately, Noren’s heat exchanger technology makes it possible to cool electrical enclosures without condensation or other forms of contamination and without consuming excessive amounts of energy.

How Condensation Forms in an Enclosure
Condensation forms when warm, humid air comes into contact with a significantly cooler surface. The moisture in the warm air changes from gas to liquid when it cools, forming drops of condensation. In air-conditioned electrical enclosures, heated air can condense on the surfaces of the cooled enclosure, and the condensation can gradually erode and damage sensitive electrical components.

How to Keep Cool Without Condensation
Unlike air conditioning or compressed air, the air within a Noren heat exchanger is not forcibly chilled through compression or with an additional refrigerant. On the contrary, our green energy heat exchangers harness energy-efficient solutions, such as natural and forced convection, to keep the internal atmosphere of the enclosure just above the ambient temperature outside. Ambient heat exchangers also operate within a closed-loop system, so condensation and air contamination from outside never reach the equipment inside the enclosure.

Customized Ways to Cool Electrical Enclosures More Efficiently
Condensation is one of many potential pitfalls of relying on air conditioning units to cool your electrical enclosures continuously. Fortunately, our ambient and below-ambient cooling units can address most of them.
