JTF-2
Frost protection thermostat, capillary length 6m, external setting, external resetting
For securing hot water heating coils against freezing. The unit is intrinsically safe and has a sealable setpoint adjustment.
For measuring the temperature of non-aggressive gases. When fixing the capillary tube, mounting brackets JZ-05 / 6 M (metal) or JZ-05 / 6 K (plastic) should be used upstream of the heating coil. The capillary tube is active along its entire length. The device reacts when approx. 30 cm of the capillary tube reaches the adjusted scale value. Mounting brackets, immersion sleeves and protective coils are not included in the delivery and must be ordered separately.
