FLZ 510 – FLZ 530 - Pfannenberg

Thermostats

The FLZ series of thermostats consists of three versions. They are available with N.C. / N.O. and changeover contacts. In combination with control cabinet heaters, they control temperature inside the control cabinet. In combination with filterfans, they provide additional savings on energy, materials and time and, hence, provide a better environmental balance. All in all, this results in greater reliability of the production process, reduced energy consumption due to need-based use and an improvement in the efficiency of the controlled heaters and filterfans
