Reliable Heating for Electrical Control Cabinets

Radiant enclosure heaters such as the Pfannenberg FLH 030 help maintain suitable internal cabinet conditions when electrical equipment is exposed to low ambient temperatures or changing humidity. By raising the internal enclosure temperature, the heater helps reduce the likelihood of condensation forming on sensitive electrical and electronic components and therefore helps protect equipment against moisture-related corrosion.

The FLH series is designed for industrial thermal management and is commonly used together with a thermostat or hygrostat where automatic temperature or humidity control is required. Its robust fanless construction, compact dimensions and DIN-rail mounting system make the FLH 030 particularly suitable for dependable heating in machinery, automation and electrical control systems.

Typical Applications

• Electrical control cabinets and switchgear enclosures.
• Industrial automation control panels.
• PLC and electronic equipment cabinets.
• Machinery and production equipment enclosures.
• Small electrical and instrumentation cabinets.
• Installations requiring protection against condensation and excessive humidity.
