Purchase now: Pfannenberg 17050610030 FLH 400 Fan Heater
Purchase now: Atlantech Drives provides you the Pfannenberg 17050610030 (Model: FLH 400), a high-capacity 400 Watt Fan Heater designed to provide active climate protection in large electrical enclosures. Unlike passive radiant heaters, the FLH 400 utilizes a high-quality axial fan to circulate heated air throughout the cabinet (approx. 50 m³/h). This forced convection is critical for eliminating «cold pockets» in the corners of the enclosure where condensation typically forms, leading to corrosion and short circuits in sensitive automation equipment.
Technical Specifications and Performance
The 17050610030 operates at 230 V AC (50/60 Hz) and delivers a powerful 400W heating output. It is housed in a touch-safe plastic casing (UL 94 V-0) that protects maintenance personnel from accidental burns. The unit is designed for continuous operation and features a robust terminal block connection. Because it does not have an integrated thermostat, it offers the flexibility to be controlled by an external precision hygrostat (like the FLZ 610) or a twin thermostat (FLZ 540) for exact dew point management.

Expert Installation Advice: External Control Logic
Since this specific part number does not include an onboard thermostat, Expert Tip: Always wire it in series with a Pfannenberg FLZ 510 or similar thermostat. Set the thermostat to approximately +10°C. This ensures the heater only runs when the temperature approaches the dew point, saving energy. If humidity is your primary concern (e.g., outdoor water treatment plants), wire it in parallel with a hygrostat set to 60% RH to trigger the heater regardless of temperature.
Frequently Asked Questions (FAQs)
Q: What is the clearance required?
A: Due to the 400W output, ensure at least 100mm clearance above (exhaust) and 50mm below (intake) to prevent the unit from overheating its own thermal cutout.
Q: Is the fan always on?
A: In the standard wiring configuration, the fan and heating element turn on/off simultaneously when the external controller calls for heat.
