Pfannenberg Thermostat

Thermostats are used as temperature controllers to manage filter fans or cabinet heaters. They are designed as open/close and changeover switches. In combination with cabinet heaters, they can ensure, especially in outdoor applications, that the cabinet is 'artificially' dehumidified in addition to temperature control. This means that the temperature is maintained above the dew point to prevent water from condensing out of the air, which could lead to short circuits due to condensation. The combination with filter fans offers additional savings in energy, materials, and time, resulting in a better environmental balance and increased safety in the production process through reduced energy consumption and improved efficiency of the filter fans.

The series of twin thermostats combines two thermostats in all combinations for complex switching tasks.

FLZ510 as a changeover switch with snap action:

• Suitable for controlling fans and heaters
• Switching temperature differential 1K
• Switching point tolerance +/-3K
• Adjustable range 20°C to 80°C

Thermostats for every application:

• FLZ510: Changeover switch with snap action
• FLZ520: Normally open switch with snap action (suitable for controlling heaters)
• FLZ530: Normally closed switch with snap action (suitable for controlling fans)
• FLZ541: Normally open and normally closed switch with snap action in one housing
• FLZ542: Two normally open switches with snap action in one housing
• FLZ543: Two normally closed switches with snap action in one housing

The advantages of the series at a glance:

• Suitable for all applications in the industry
• No influence from electromagnetic radiation, as a mechanically switching contact is installed
• Extends the service life of heaters and fans
• Optimized energy consumption for heaters and filter fans
• Easy mounting on DIN rails
• Electrical connection via screw terminals
• IP 20 protection for installation inside the cabinet
• Approvals: cURus, EAC.
