Purchase now: Pfannenberg 17050615030 FLH 400 Fan Heater (115V)
Purchase now: Atlantech Drives provides you the Pfannenberg 17050615030 (Model: FLH 400), a powerful 400 Watt Fan Heater specifically wound for 115 V AC power sources. This active thermal management unit is designed to prevent condensation and maintain minimum operating temperatures in large electrical enclosures, particularly for the North American market or facilities utilizing 110-120V control voltage. By keeping the internal temperature above the dew point, the FLH 400 effectively eliminates the risk of corrosion and leakage current that can destroy sensitive PLCs and drives.
Technical Specifications and Active Heating
Unlike passive radiant heaters, the FLH 400 integrates a high-quality axial fan that circulates air at approximately 50 m³/h. This forced convection is critical for larger cabinets where stagnant air pockets can lead to localized freezing. The unit distributes the 400W of heat energy evenly, ensuring a uniform temperature profile.

Expert Installation Advice: External Thermostat Logic
This heater operates as a «slave» unit (no internal thermostat). Expert Tip: For maximum efficiency, wire it in series with a Pfannenberg FLZ 510 Thermostat (Red Dial) set to +10°C. If you are in a high-humidity environment (e.g., wastewater treatment), consider wiring it in parallel with an FLZ 610 Hygrostat. This ensures the heater turns on if humidity spikes (>60% RH), even if the temperature is relatively warm, providing double protection against condensation.
Frequently Asked Questions (FAQs)
Q: Can I connect this to 230V?
A: No! This is the 115V version. Connecting it to a European 230V grid will cause immediate catastrophic failure of the heating element and fan motor. Always verify the voltage label.
Q: What is the required clearance?
A: Due to the high heat output (400W), maintain at least 100mm clearance above the air outlet and 50mm below the intake to prevent overheating.
