Critical Thermal Management Solutions for Maximum Uptime and Efficiency

cooling technology for electrical enclosures

For more than 60 years, Pfannenberg strives to satisfy the increasing demands of modern industries to protect electrical enclosures through innovative and safe process cooling. With proper enclosure climate control, you can improve the longevity of critical electronics.
To ensure that sensitive electronics maintain their rated life expectancy and that they function reliably, proper regulation of the enclosure climate is necessary. Electronics are typically most efficient in an environment where the humidity is low and the temperature is approximately 95°F. As the temperature in an enclosure rises it can have a lasting effect on the electronics. Tests have shown that an increase in temperature of as little as 18°F shortens the life expectancy of electrical components by more than 50%.

Proper thermal management is necessary. This prevents critical temperature fluctuations, avoids overheating and protects against the formation of condensate. It is essentially the backbone of your entire production process, prolonging the life of your electronics and protecting your investment.

Filter Fans to Optimize Airflow

Pfannenberg Filter fans are the choice for forced convective cooling to circulate and cool airPfannenberg filter fans in cabinets. With low energy consumption, unrivaled airflow, and up to 300% longer lifetime than competitors, filter fans offer safe and economical cooling of your electrical enclosures.
  • Reduced energy consumption
  • NEMA type protection
  • Patented tool-less four corner fastening system

Cooling Units - Thermal Protection for Critical Electronics

Pfannenberg cooling units operate on the principle of the Carnot cycle. This means that the cooling unit functions
as a heat pump that “pumps” the thermal energy transferred from the electronic cabinet (heat dissipated from the
components) up to a higher level of temperature (the ambient temperature can reach levels as high as + 55 °C). The air
inside the enclosure is cooled down by the evaporator and at the same time dehumidified.

Air/Water Heat Exchangers Provide Efficient Cooling Even in the Worst Conditions

When ambient temperatures are high or the atmosphere is oily and dusty, Pfannenberg Air/Water Heat Exchangers provide safe cooling. Ideal areas of use for air/water heat exchangers are wherever machines or production processes are cooled by tempered water and water is already provided.
Air/Water Heat Exchangers use a water source to remove the heat from the electrical cabinet.The heat from the enclosure is transferred to fluid and the heated fluid is then piped away adding no heat to the ambient environment.

How do you know if an Air/Water Heat Exchangers is the right product for your application?
  •  If there is a chilled water supply readily available at the enclosure.
  •  If the environment has extreme conditions like extremely high ambient, extremely dirty or caustic, that make other systems not applicable.
