Common misconceptions about Heat Exchangers

January 19, 2026


Most common questions
Often, the questions that arise with the Heat Exchanger are related to its cooling power; most people think it has lower cooling power than other available technologies for cooling electrical cabinets. Can't be more wrong. Heat Exchangers have a greater cooling capacity than many other equipment used for cabinet cooling. The best part is that they don't require a large space or a huge amount of energy to operate.

Cooling capacity
We can find air-to-air and air-to-water heat exchangers. Air-to-water units provide the best cooling capacity. At Noren, we have air-to-water units with a cooling capacity of up to 16,680 watts. Each unit is customized to the electrical cabinet where it will operate, taking into account the dimensions, cooling capacity, and mounting location of the electrical panel.

Advantages
Heat Exchangers provide higher protection against humidity than an air conditioner. AC can allow undesired humidity to ingress into the electrical panel, since it can lower the temperature below the dew point when not correctly dimensioned. No maintenance is required; the units don't need experienced personnel or specialized tooling for installation.
