ESBE series CTF150 is a flue gas thermostat, consisting of a temperature probe connected to a switch unit. The switch unit can be used to control the electricity supply to a circulation pump or load unit with an integrated circulation pump.


The thermostat switch can easily be set to any target temperature between 20°C and 240°C by turning the setting knob. If needed, the temperature range can be limited by changing the position of pegs inside the housing of the switch unit.


The temperature probe can be mounted either directly on the outside of the flue gas pipe, or inside the pipe using the immersion pocket series CTF851. The switch unit is prepared for easy wall mounting. The temperature probe is connected to the switch unit by a 1500 mm line.
