The FLZ series of thermostats consists of three-versions. They are available with NC/ NO and changeover contacts. In combination with control cabinet heaters, they control temperature inside the control cabinet. In combination with filter fans, 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 filter fans.
