Purchase now: Atlantech Drives provides you the Pfannenberg 17025310007 (Model: FLH-T 250), a high-efficiency 250 Watt Fan Heater with an integrated thermostat. In industrial environments with fluctuating temperatures, condensation is the silent killer of electronics. The FLH-T 250 is engineered to prevent the formation of condensation inside electrical enclosures by maintaining a stable temperature above the dew point. Unlike passive convection heaters, this unit utilizes a powerful fan to distribute warm air evenly throughout the cabinet, eliminating dangerous «cold spots» where moisture could collect on sensitive busbars or drive terminals.
Technical Specifications and Integrated Control
The 17025310007 operates at 230 V AC (50/60 Hz) and delivers 250W of heating power. Its distinguishing feature is the built-in fixed-point thermostat, which automatically regulates the heater’s operation. This «smart» control not only saves energy by running the heater only when necessary but also simplifies installation by eliminating the need for external wiring to a separate hygrostat or thermostat controller.

Expert Installation Advice: Optimal Positioning
To get the most out of the FLH-T 250, placement is key. Expert Tip: Always install fan heaters at the bottom of the enclosure. Heat rises naturally, and the fan will accelerate this convection. Ensure there is at least 100mm of clearance below the intake and above the exhaust to prevent the unit from short-cycling (overheating itself before heating the cabinet volume). Never point the hot air discharge directly at plastic wire ducts or temperature-sensitive components like batteries.
Frequently Asked Questions (FAQs)
Q: What is the starting current?
A: Fan heaters have a lower inrush current compared to PTC heaters, but you should still calculate the circuit breaker based on the fan motor’s startup load combined with the resistive element.
Q: Can this replace a generic strip heater?
A: Yes, and it is far superior. A 250W fan heater heats the cabinet volume much faster and more uniformly than a 250W passive strip heater, which only heats the air immediately around it.
