The Pfannenberg FLH250 enclosure heater is designed to prevent condensation and temperature-related issues inside electrical enclosures. It delivers a steady 250 W heat output using a 230 V AC supply, helping keep internal components dry and operating within a safe temperature range. This heater is typically used in control panels, switch cabinets, and automation enclosures where moisture and cold conditions can cause failures over time.
The FLH250 works by gently warming the air inside an enclosure. This reduces humidity and stops condensation from forming on sensitive electrical and electronic parts.
With dimensions of 183.5 × 85 × 104 mm, the heater fits easily inside standard enclosures without taking up unnecessary space. It is usually mounted on a DIN rail, making installation straightforward during panel assembly or retrofitting.
It is especially useful in environments where temperature drops or humidity levels fluctuate.
