JTF-3 W
Frost protection thermostat, capillary length 1.8m, internal setting
For securing hot water heating coils against freezing. The unit is intrinsically safe and has a sealable setpoint adjustment.
Protective coil SW-200-12 must be used for measuring the temperature of non-aggressive gases in the duct; immersion sleeve TH-140 must be used to measure temperatures in non-aggressive fluids; in aggressive fluids, immersion sleeve NTH-140 must be used. Mounting brackets, immersion sleeves and protective coils are not included in the delivery and must be ordered separately.
