Purchase now: Pfannenberg 17020610030 FLH 250 Fan Heater (230V)
Purchase now: Atlantech Drives provides you the Pfannenberg 17020610030 (Model: FLH 250), the industry-standard 250 Watt Fan Heater for 230 V AC applications. In environments with fluctuating temperatures, the dew point inside an enclosure can be reached quickly, causing condensation to form on copper busbars and electronics. The FLH 250 prevents this by maintaining a stable temperature slightly above ambient, ensuring high system availability and safety.
High Efficiency and Compact Design
The FLH 250 combines a heating element with a durable axial fan (approx. 50 m³/h airflow). This forced circulation is far superior to static heating because it homogenizes the temperature profile inside the cabinet. The unit is designed for DIN Rail mounting, making it easy to snap into existing control panels during retrofits. The spring-clamp or screw terminals allow for secure, vibration-resistant wiring.

Maintenance Expert Tips: Thermostat Integration
This unit is designed to be controlled externally. Expert Tip: Wire it in series with a Pfannenberg FLZ 510 Thermostat (NC contact) or an FLZ 610 Hygrostat. Do not rely on the machine’s main PLC to control the heater, as the heater needs to function even when the machine is powered down (e.g., over the weekend) to prevent condensation. A dedicated live circuit with a thermostat is the best practice.
Frequently Asked Questions (FAQs)
Q: What is the lifespan of the fan?
A: Pfannenberg uses high-quality ball bearing fans rated for ~40,000 hours at 40°C. Since the heater only runs intermittently (controlled by thermostat), it typically lasts for 10+ years.
Q: Can I touch the heater while it’s on?
A: The housing is «touch-safe» plastic, but the air outlet grille gets hot. Caution should still be exercised during maintenance.
