THERMASREG ®
The mechanical frost protection thermostat ⁄ frost monitor THERMASREG
or with mechanical locking and manual reset, is available with capillaries in lengths of 0.6 m, 1.8 m, 3 m, 6 m, or 12 m. This frost protection monitor
is used for air- and water-side temperature monitoring at heat exchangers, water circulation systems, and heating registers to prevent freezing up
and to avoid frost damages, e. g. in ventilation and air conditioning ducts. All devices are self-secure with sensor breakage detection. In case of
damage to the capillary tube – membrane system, the relay automatically switches to heating function. THERMASREG
monitoring liquids. The sensor tube can be installed inside an immersion sleeve. Mounting clamps MK - 05 -K are included in the delivery.
