Frequently Asked Questions
When should I choose a Filterfan rather than a cooling unit
Use Filterfans where the ambient air is cooler than the target enclosure temperature and airborne contamination is manageable. Choose a cooling unit for high ambient conditions, dusty areas or where you need closed loop cooling.
How do I size Pfannenberg cooling or ventilation for my panel
Estimate the heat load from devices, add a safety margin, then select a Filterfan or cooling unit that provides sufficient heat removal at your ambient conditions. Share a parts list and we can recommend a model.
Why add a heater inside an enclosure
Heaters prevent condensation and maintain minimum temperatures to protect electronics during cold starts or in humid sites. Pair with a thermostat or hygrostat for control.
What setpoints are typical for thermostats and hygrostats
Common settings are around 35 to 40 percent RH for hygrostats and 5 to 10 degrees Celsius above the expected minimum for thermostat control. Adjust for site and component limits.
