Thermal Management | Signaling Technology
Pfannenberg is a renowned leader in thermal management and signaling technology, providing energy-efficient, durable, and service-oriented products for over 50 years across various industries worldwide.
Pfannenberg offers a range of signaling devices for industrial applications, including flashing lights, sounders, and signal towers, designed for reliability and safety.
- Filterfans: Economical solutions for environments where ambient temperature is lower than required, creating slight overpressure to assist natural convection.
- Air/Air Heat Exchangers: Suitable for harsh conditions, separating external and internal air circuits to protect against dust and fluids.
- Cooling Units: Used when ambient air is contaminated or insufficient for cooling.
- Air/Water Heat Exchangers: Ideal for high IP class requirements or when thermal energy cannot be dispersed to surroundings.
Combining air/water heat exchangers with chillers enhances cooling efficiency. Using filterfans with thermostats can lead to energy savings and extended service life.
Features include a patented fastening system for easy installation, optimized airflow, and optional thermostats for energy efficiency, offering protection up to IP 55.
Pfannenberg provides comprehensive cooling services supported by an international network.

THERMAL MANAGEMENT OF ELECTRICAL ENCLOSURES: Determine the correct air conditioning products When can Filterfans be used? If the ambient temperature is always lower than the temperature required in the electrical enclosure, then filterfans represent an economical solution for thermal management of electrical enclosures. Important for the use of Filterfans Use filterfans to force the surrounding air into the electrical enclosure, so that a slight overpressure builds up inside the enclosure. The surrounding air enters the electrical cabinet exclusively via the filterfan, which ensures that it is...
