Pfannenberg thermal management for control panels and machines: PF filterfans from 17 to 560 CFM, enclosure air conditioners for NEMA 12, 3R and 4X cabinets, PWS air to water heat exchangers from 2,218 to 34,121 Btu/h, and EB and CCE packaged chillers from 2.4 to 44.4 kW. Applied Control is the Pfannenberg manufacturers representative.
Pick the method by the air outside the panel. If it is cooler and clean, a filterfan moves the heat out. If it is hot, dirty or oily, keep the cabinet sealed with an air conditioner or an air to water heat exchanger. Start with the enclosure heat load calculator: panel size, internal watts and ambient give you the BTU/hr to remove. Send that number, or the Hoffman or Rittal part you run today, and the quote comes back the same business day.
