1. Pfannenberg Thermostat FLZ 510 0...+60C
Thermostats are used as temperature controllers for managing filter fans or cabinet heaters. They are available as normally open/normally closed and changeover types. When combined 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 a snap contact, is suitable for controlling fans and heaters. The switching temperature difference is 1 K, the switching point tolerance is +/- 3 K, and the setting range is from 20 °C to 80 °C.
Thermostats for every application:
- FLZ510: Changeover switch with snap contact
- FLZ520: Normally open with snap contact (suitable for controlling heaters)
- FLZ530: Normally closed with snap contact (suitable for controlling fans)
- FLZ541: Normally open and normally closed with snap contact in one housing
- FLZ542: Two normally open with snap contact in one housing
- FLZ543: Two normally closed with snap contact 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 used
- 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.

2. Pfannenberg Control cabinet thermostat
The FLZ twin thermostats series integrates three independently switching thermostats. They are designed as normally open/normally closed, normally open/normally open, and normally closed/normally closed. Unlike thermostats with changeover contacts, connected devices can be switched in different temperature ranges.

3. Pfannenberg HYGROSTAT THERMOSTAT 40-90% (FLZ 610)
Hygrostats control control cabinet heaters or filter fans regarding the exceeding of a set relative humidity. This keeps the relative humidity above the dew point and prevents water from condensing on electrical components as well as corrosion on unprotected metal sheets. An electronic combination device combines a thermostat and a hygrostat in one housing.
The advantages of the series at a glance:
- FLZ600: mechanical changeover switch with snap contact
- FLZ610: electronic combination device hygrostat/thermostat
- Humidity control for all applications in industry
- Especially suitable for environments with high humidity
- Protection against condensation before it occurs
- Easy mounting on DIN rails
- Electrical connection via screw terminals
- Approvals: cURus, EAC FLZ 610 HYGR. 230 AC 40-90% rF.
