Purchase now: Atlantech Drives provides you the Pfannenberg 17030610030 (Model: PFH 300), a high-performance 300 Watt Fan Heater from the advanced PFH series. Designed for space-constrained industrial enclosures, the PFH 300 offers a superior power-to-size ratio compared to older heater models. Operating at 230 V AC, it utilizes a PTC (Positive Temperature Coefficient) heating element combined with a high-velocity axial fan to protect your electronics from low temperatures and dangerous condensation buildup.
Technical Specifications and Compact Efficiency
The PFH 300 is distinct from the FLH series due to its more compact footprint, making it ideal for densely populated control panels where DIN rail space is at a premium. The integrated fan delivers an airflow of approximately 50 m³/h, ensuring rapid heat distribution. The touch-safe plastic housing (UL 94 V-0) prevents accidental burns to maintenance personnel and allows for closer mounting to other components compared to open-element heaters.

Expert Installation Advice: External Control Required
This model is a «continuous operation» or «slave» heater, meaning it does **not** have an integrated thermostat. Expert Tip: To achieve energy efficiency and precise dew point control, you must wire this unit in series with a Pfannenberg FLZ 510 Thermostat (Red Dial) or an FLZ 610 Hygrostat. This setup ensures the heater only runs when necessary (e.g., below 10°C), extending the life of the fan motor.
Frequently Asked Questions (FAQs)
Q: What is the difference between PFH and FLH heaters?
A: The PFH series is more compact and typically features a more modern, streamlined housing design optimized for vertical airflow in tight spaces.
Q: Can I mount it near the cable ducts?
A: Maintain at least 100mm clearance above the hot air outlet to prevent melting of PVC wire ducts or cable insulation.
