Pfannenberg air-air heat exchangers

Using ambient air for the thermal management of electrical enclosures is the most economical and energy-efficient method of cooling. However, in many applications the ambient air can be contaminated by dust, liquid or gases. This means the components inside the enclosure can become defective or damaged if contact occurs with contaminants in the environment. The use of a filter fan is therefore no longer possible under these conditions.

The Pfannenberg air-air heat exchangers are designed to be a solution for these environmental conditions. Due to careful design, a complete separation of the internal and external airflow is made possible. The interior of the enclosure is hermetically separated from the atmosphere, meaning harmful dust and fluids can’t cause any damage to the sensitive electrical components inside.

Because of the sealed nature of the heat exchangers, no maintenance schedule is necessary, saving on costly service contracts or maintenance shutdowns. Installation can be handled by a single service technician in as little as 3 min due to the design of the fastening system, providing significant savings on labour costs.

An integrated thermostat looks after the running costs by ensuring the heat exchanger is only operational when cooling is required.
