Frost thermostat, 1.8 m capillary, IP65, hysteresis 1.5K, STW, internal setting, external reset | RTKSA-204.020<\/p>\n
The RTKSA frost protection controllers are specially developed for air-side or water-side frost protection of heating coils and heat exchangers in ventilation, heating or air conditioning systems. If the Sensor breaks, contact 1 \u2013 2 is permanently open and contact 1 \u2013 4 is permanently closed.<\/p>\n
Mounting brackets, immersion sleeves and protection coils are not included in the delivery and must be ordered separately. Air-side application: The SWK-2-xxx protection coils can be used to measure the temperature of non-aggressive gases in the duct. Water-side application: For temperature measurement in non-aggressive liquids, the immersion sleeves THK-2-xxx can be used, and in aggressive liquids, the immersion sleeves NTHK-2-xxx can be used.<\/p>\n
