K-FST1 Frost thermostat

-10 - +12°C

Art. no.: 2636

Frost protection thermostat

Especially suited to ensure the protection of hot water coil heating systems against freezing. The frost protection thermostat models are equipped with two switching outputs that provide the option to act on the system already in advance of the attaining of the corresponding danger point. All devices are fail-safe and dispose of a lead-sealable set value setting facility. In each case, the capillary tubes are active over their entire length.. Capillar length: 6.0 M. capillar is active on the whole length. The device responds if the adjusted scale value is attained over a length of approx. 30 cm 60 cm respectively. Specially suited for the measuring of temperatures in non-aggressive gases. The bracing of the capillary tubes in front of the coil heating system can be realised by means of installation clips.
