Pfannenberg introduces Series PFH enclosure heater

April 10, 2015 - Pfannenberg introduces Series PFH enclosure heater to help maintain clean and dry conditions within electrical enclosures, control cabinets, consoles, and kiosks.

 Series PFH measures 3.5 x 5.6 x 5.0 inches, and are offered in a range of heating capacities from 200 to 1200 Watts. The PTC (positive temperature coefficient) heating elements provide fast heating and are self-regulating to promote safety. PTC heating elements automatically limit current draw and output wattage as temperature rises.

Additional features include the following:

  • ABS touch-safe housing verified to UL 94V-O
  • Internal air-circulating fan
  • Choice of a built-in single-point thermostat, variable thermostat, or no thermostat (for operation with a remote thermostat or hygrostat)
  • Spring clamp terminal connections for ease of wiring
  • Surface mounting or DIN rail mounting capability
  • 115 or 230 VAC operation
  • UL Recognized

Typical applications for the PFH compact fan heater include the following:

  • Traffic Signal Control Boxes
  • Automated Teller Machines (As)
  • Information and Payment Kiosks
  • Outdoor Electrical Power Enclosures
  • Switch Gear and Control Panels
  • Control Valve Housings
  • Clothing Lockers
  • CCTV Surveillance Cameras
  • Wind and Solar Power Systems
  • Electrical and Electronic Control Systems
  • Wireless and Broadband Telecommunications Systems
  • Parking and Access Control Systems
  • Freeze Protection


It’s vital to ensure proper and optimal functionality and to avoid costly failures of both the equipment within the enclosure and the processes for which they manage. As ambient temperatures decrease and the dew point is reached, humidity in the air will condense onto surfaces and components within the enclosure causing moisture, corrosion, and short-circuiting problems. Additionally, frost will develop as temperatures reach the freezing point – wreaking havoc on switchgear and other sensitive mechanisms. The heat generated by electrical controls within an enclosure is often adequate to ward off moisture, however, during de-energized shut down situations, this inherent convection is lost and supplementary heat becomes necessary. Enclosure heaters are widely used to keep interior temperatures above the dew point and eliminate the potential for condensation as well as to keep sensitive items such as valves, ticket printers, and HMI displays warm enough for proper functionality.
