RTKSA-204.300

The RTKSA frost protection regulators have been specially developed for air or water-side frost protection of hot water heating coils and heat exchangers in ventilation, heating or air conditioning systems. The capillaries are active along their entire length. The device responds when the minimum response length of the capillary (40 cm) reaches the set scale value. In the event of a sensor break, contact 1-2 is permanently open and contact 1-4 is permanently closed. Unlocking is no longer possible. Note: Mounting clamps, thermowells and protective coils are not included in the scope of delivery and must be ordered separately. Air-side application: For frost protection of heating registers, the capillary is clamped in front of the heating register to be protected with mounting clamps. The JZ-05/6M (metal) or JZ-05/6 K (plastic) mounting clamps must be used for this purpose.
