Overheating is one of the leading causes of premature equipment failure inside electrical enclosures. Choosing the right cooling solution helps protect critical components, improve reliability, and reduce costly downtime. Pfannenberg offers enclosure cooling solutions designed to keep your systems operating at optimal temperatures.
The Hidden Risk Inside Your Enclosure
Electrical enclosures are home to some of your most important equipment. PLCs, drives, power supplies, relays, and other components all generate heat during operation. As temperatures rise, so does the risk of unexpected failures.
Excessive heat can cause:
Reduced component lifespan
Unexpected downtime
Nuisance faults and shutdowns
Increased maintenance costs
Decreased system reliability
While many facilities focus on the equipment inside the enclosure, proper thermal management is often overlooked.
Not Every Enclosure Needs the Same Cooling Solution
One of the most common mistakes is assuming all enclosures require the same cooling method. The right solution depends on factors such as enclosure size, heat load, ambient temperature, and environmental conditions.
Filterfans®
Filterfans® are a cost-effective solution when the surrounding air is cooler than the desired enclosure temperature. They help remove excess heat while maintaining airflow throughout the enclosure.
Cooling Units
When ambient temperatures exceed the desired internal enclosure temperature, cooling units actively remove heat and maintain a controlled environment for sensitive electronics.
Air-to-Air Heat Exchangers
Heat exchangers are ideal for applications where contaminants, dust, or moisture must remain outside the enclosure while still allowing heat to dissipate.

Pfannenberg cooling solutions help maintain optimal enclosure temperatures, protecting sensitive electronics from overheating and unplanned downtime.
Whether your application requires a Filterfan®, cooling unit, or heat exchanger, selecting the right solution is critical to maintaining equipment reliability and extending component life.
Why Proper Sizing Matters
An undersized cooling solution may struggle to remove enough heat, resulting in elevated temperatures and reduced equipment life.
An oversized solution can increase energy consumption and operating costs without providing additional benefits.
To properly size an enclosure cooling system, factors such as the following must be considered:
Enclosure dimensions
Internal heat load
Ambient temperature
Desired enclosure temperature
Environmental conditions
Selecting the right cooling solution from the start helps maximize efficiency and avoid future problems.
