Purchase now: Pfannenberg 17025015107 FLH 250 Heater (115V)
Purchase now: Atlantech Drives provides you the Pfannenberg 17025015107 (Model: FLH 250), a robust 250 Watt Fan Heater specifically wound for 115 V AC power systems (common in USA, Canada, and specialized control circuits). Moisture is the enemy of electrical components. The FLH 250 provides active, forced-air heating to keep the internal cabinet temperature above the dew point, preventing the formation of condensation that leads to corrosion, leakage current, and short circuits in sensitive equipment.
Technical Specifications and Forced Convection
Unlike passive convection heaters (strip heaters), the FLH 250 features an integrated high-quality axial fan. This fan circulates air at approximately 50 m³/h, ensuring that the 250W of thermal energy is distributed evenly throughout the enclosure volume. This eliminates «cold corners» where moisture could accumulate. The unit is housed in a touch-safe plastic casing (UL 94 V-0), protecting maintenance personnel from burns during operation.

Expert Installation Advice: Preventing «Heat Short-Circuits»
Because this heater has a fan, placement is critical. Expert Tip: Ensure there is at least 100mm of clearance above the hot air outlet and 50mm below the air intake. Never mount a temperature-sensitive device (like a PLC CPU or battery backup) directly in the hot air plume. Also, verify that the 115V supply is correct; connecting this unit to 230V will destroy the element immediately.
Frequently Asked Questions (FAQs)
Q: Does this unit have a thermostat?
A: This specific part number is usually a «slave» heater. It should be controlled by an external Pfannenberg FLZ 510 Thermostat or FLZ 610 Hygrostat to save energy and provide precise control.
Q: Can I mount it horizontally?
A: Vertical mounting is required to support the natural convection of heat and to prevent internal overheating of the fan motor.
